PLACARDING INSTRUCTIONS

Each inoperative item must be placarded to inform and remind the crewmembers and maintenance personnel of
the deferred equipment condition. The crewmember (flight or maintenance) accomplishing the deferral of an
inoperative item or system is responsible for ensuring the placard is installed in accordance with these
instructions.

Any time an inoperative item is deferred on the Aircraft Discrepancy Log Sheet an INOP placard will be installed
by following these steps:

1. Record the ATA number of the deferred item on an INOP sticker. An example of the sticker appears as
follows:

2. Place the INOP placard adjacent to the control or indicator for the item deferred.
3. If the exact copy of this is not available, use a similar substitute, as long as it clearly states what the item is

in-operative.

NOTE: Due to the complexity of some controls/indications, some systems will require more than one placard.

4. In the event there is no control or indication for the deferred item, a placard will be installed on the
instrument panel in plain view of both pilots.

5. If an Inoperative item affects RVSM capability, a RVSM placard will be installed in plain view of the pilot to
read “NO RVSM”.

Some deferral items require specific language be inserted on the INOP placard, this language will be found in the
“Maintenance & Placarding Procedures” column of the specific MEL item. When an item is deferred that contains
specific placarding procedures, it is the responsibility of the crewmember accomplishing the deferral to insert this
language in addition to the instructions above.

Deferred items will be identified in the front of the MEL in a clear plastic case on the MEL Deferral Card.
Instructions for completing the card are adjacent to the card in the plastic containing in front of the MEL. Once the
deferred item is cleared, the card will be discarded.

FLEET MEL POLICY

A Fleet MEL will be implemented when Dumont Aircraft Charter, LLC. obtains more than one aircraft of the same
make and model to their certificate. The Fleet MEL will address which aircraft are included in the manual on both
the front cover of the MEL as well as on Page 1-1. Any differences in equipment between the aircraft included in
the fleet MEL will be noted in Column 1 of the MEL, directly under the System & Sequence Number. When all
aircraft have the same number of any equipment installed, no notation of tail number will be listed in Column 1 of
the MEL.

A Fleet MEL will receive a numbered revision when any new aircraft of the applicable type is added to the
certificate. Regular numbered revisions will also be applied to a Fleet MEL whenever a revision to the Master
Minimum Equipment List is issued by the FAA.

DEFINITIONS

2. Administrative Control Item (ACI). An ACI is listed by the aircraft operator in the MEL for tracking
and informational purposes. As an example, ACI may be used to track ETOPS accomplishment of
required APU cold-soak, or in-flight verification starts. An ACI may be added to an aircraft operator’s
MEL by approval of the POI provided no relief is granted, or provided conditions and limitations are
contained in an approved document (e.g., Structural Repair Manual (SRM) or Airworthiness
Directive (AD)). If relief other than that granted by an approved document is sought for an ACI, a request
must be submitted to the Administrator. If the request results in review and approval by the FOEB, the
item becomes an MMEL item rather than an ACI.

3. ATA System Page. The ATA system page is divided into four (4) columns and contains: item and
repair category; number installed; number required for dispatch; and remarks or exceptions. Standard
ATA categories are used. Items are numbered sequentially.

A. Item. This column depicts the equipment, system, component, or function listed in the “Item”
column.

B. Repair Category. See definition #24.

C. Number Installed. This column depicts the number (quantity) of instrument and equipment items
normally installed in the aircraft. This number represents the aircraft configuration considered in
developing this MMEL. Should the number be a variable (e.g., fleet configuration differences, cockpit
lighting items, cabin lighting items, cargo restraint components) a number is not required and the “-”
symbol is used.

D. Number Required for Dispatch. This column depicts the minimum number (quantity) of
instrument and equipment items required for operation provided the conditions specified in the “Remarks
or Exceptions” column are met. Where the MMEL shows a variable number required for dispatch, the
MEL must reflect the actual number required for dispatch or an alternate means of configuration control
approved by the Administrator.

E. Remarks or Exceptions. This column may include a statement(s) either prohibiting or
permitting operation with a specific number of instrument and equipment items inoperative, provisos
(conditions and limitations) for such operation, and appropriate notes.

F. Provisos. Provisos are indicated by a number or a lower case letter in “Remarks or
Exceptions”. Provisos are conditions or limitations that must be complied with for operation with the
listed instrument or equipment item inoperative.

G. Notes. Notes provide additional information for crewmember or maintenance consideration.
Notes are used to identify applicable material, which is intended to assist with compliance, but do not
relieve the aircraft operator of the responsibility for compliance with all applicable requirements.
Additional notes may be amended, deleted, or added to the MEL by the aircraft operator, as
appropriate. Notes are not a part of the provisos.

H. Vertical Bar (change bar). A vertical bar indicates a change, addition, or deletion in the
adjacent text for the current revision of that page only. All change bars applicable to the previous
revision of the MMEL are removed prior to the release of the next revision.

4. Airplane Flight Manual (AFM), Rotorcraft Flight Manual (RFM). The FAA-approved AFM/RFM
is the document approved by the responsible FAA Aircraft Certification Office (ACO) during type
certification. The approved flight manual for the specific aircraft is listed on the applicable Type
Certificate Data Sheet (TCDS). The approved flight manual is the source document for operational

Sundance Aviation MINIMUM EQUIPMENT LIST

AIRCRAFT FAA MMEL Revision REVISION NO. DATE PAGE NO.

HS-125 Fleet Rev 8d Original 08/20/2016 1-5

limitations and performance parameters for an aircraft. The term “approved flight manual” can apply to
either an AFM or an RFM. The FAA requires an approved flight manual for aircraft type certification.

5. As Required by 14 CFR. When the MMEL states, “As Required by 14 CFR,” the listed instrument
or equipment item is subject to certain provisions (restrictive or permissive) expressed in the 14 CFR
operating rules. The number of items required by 14 CFR must be operative. When the listed item is
not required by 14 CFR, it may be inoperative for the time specified by repair category. The term
“14 CFR” has replaced “FAR” as the current reference to Federal Regulations pertaining to aviation.
However, many, if not most, MMELs still contain the acronym “FAR”; therefore, this acronym is
acceptable and retained in PL-25 and this definition.

6. Code of Federal Regulations (CFR) and Federal Aviation Regulations (FAR). CFR, the
current term, and FAR both refer to the applicable portions of the Federal Aviation Act and
Code of Federal Regulations.

7. Considered Inoperative. The phrase, “Considered Inoperative”, as used in the provisos,
means that an instrument and equipment item must be treated for dispatch, taxi and flight
purposes as though it were inoperative. The item will not be used or operated until the original
deferred item is repaired. Additional actions include: documenting the item on the dispatch
release (if applicable), placarding, and complying with all remarks, exceptions, and related
MMEL provisions, including any (M) and (O) procedures and observing the repair category.

8. Continuing Authorization – Single Extension. An aircraft operator who has the authorization to
use an FAA-approved MEL may also have the authority to use a continuing authorization to approve a
single (one-time) extension to the repair interval for category B or C items in accordance with
Operations Specification D095. Continuing Authorization – Single Extension is not authorized for repair
category A and D items.

9. Dash (-). Indicates a variable number (quantity) of the instrument and equipment items may be
installed or required for dispatch. This is common when a fleet MEL is used since aircraft of the same
make and model may have differing numbers of specific instrument and/or equipment items installed.

10. Day of Discovery. This is the calendar-day an equipment/instrument malfunction was recorded in
the aircraft maintenance record/logbook. This day is excluded from the calendar-days or flight-days
specified in the MMEL for the repair interval of an inoperative instrument and/or equipment item. This
provision is applicable to all MMEL items; i.e., categories A, B, C, and D.

11. Deactivated and/or Secured. When the MMEL refers to an instrument and/or equipment item as
deactivated and/or secured, the specified component must be put into an acceptable condition for safe
flight. An acceptable method of deactivating and/or securing will be established by the aircraft operator.

12. Deleted. "Deleted" in the remarks column after a sequence item indicates that the item was
previously listed but is now required to be operative if installed in the aircraft.

13. Extended Range Operations (ER). ER refers to extended range operations (ETOPS) of an
airplane with operational approval to conduct ETOPS in accordance with the applicable regulations.

14. Excess Items. Excess items are those instrument and equipment items that have been installed
that are redundant to the requirements of the 14 CFR.

15. Flight Day. A flight-day is a 24-hour period (from midnight to midnight) either universal coordinated
time (UTC) or local time, as established by the aircraft operator, during which at least one flight is
initiated for the affected aircraft.

Sundance Aviation MINIMUM EQUIPMENT LIST

AIRCRAFT FAA MMEL Revision REVISION NO. DATE PAGE NO.

HS-125 Fleet Rev 8d Original 08/20/2016 1-6

16. Heavy Maintenance Visit (HMV). HMV is a scheduled C-check/D-check or airworthiness
maintenance program inspection where the aircraft is scheduled to be out of service for 4 or more
days.

17. Icing Conditions. An atmospheric environment that may cause ice to form on the aircraft
(structural) or in the engine(s) (induction).

18. Inoperative. A system and/or component malfunction to the extent that it does not accomplish its
intended purpose and/or is not consistently functioning normally within its approved operating limit(s)
and/or tolerance(s).

19. Inoperative Components of an Inoperative System. Inoperative instrument and equipment
items, which are components of a system that is inoperative, are usually considered components
directly associated with and having no other function than to support that system (warning/caution
systems associated with the inoperative system must be operative unless relief is specifically
authorized per the MMEL).

20. Is Not Used. The phrase “Is Not Used” in the provisos, remarks or exceptions for an MMEL
instrument or equipment item may specify that another item in the MMEL “is not used”. In such cases,
crewmembers must not activate, actuate, or otherwise utilize that item under normal operations. It is
not necessary for aircraft operators to accomplish the (M) procedure(s) associated with the item.
However, operational requirements must be complied with, and an additional placard must be affixed,
to the extent practical, adjacent to the control or indicator for the item that is not used. This informs
crewmembers that an instrument or equipment item is not to be used under normal operations.

21. Nonessential Equipment and Furnishings (NEF). NEFs are those items installed on the aircraft
as part of the original type certification (TC), STC, engineering order, or other form of alteration that
have no effect on the safe operation of flight and would not be required by the applicable certification
rules or operational rules. They are those items that, if inoperative, damaged, or missing, have no
effect on the aircraft’s ability to be operated safely under all operational conditions. NEF items are not
instrument and equipment items already identified in the MEL or CDL of the applicable aircraft. They
do not include instrument and equipment items that are functionally required to meet the certification
rule or for compliance with any operational rule.

22. Operative. An operative system and/or component will accomplish its intended purpose and is
consistently functioning normally within its design operating limit(s) and tolerance(s). When an MMEL
item specifies that an item of equipment must be operative, it does not mean that it’s operational status
must be verified; it’s to be considered operative unless reported or known to be malfunctioning. When
an MMEL item specifies that an item of equipment must be verified operative, it means that it must be
checked and confirmed operative at the interval(s) specified for that MMEL item. When an MMEL item
specifies that an item of equipment must be verified but no interval is specified, verification is required
only at the time of deferral.

Other terminology sometimes used interchangeably with “operative” within the MMEL is “operates
normally”, "fully operative", and "considered operative”. The aircraft operator's MEL may incorporate
standardized terminology of the aircraft operator’s choice to specify that an item of equipment must be
operative, provided the aircraft operator's MEL definitions indicate that the selected "operative"
terminology means that the required item of equipment will accomplish its intended purpose and is
consistently functioning normally within its design operating limit(s) and tolerance(s).

23. Placarding. Each inoperative instrument or equipment item must be placarded to inform and
remind the crewmembers and maintenance personnel of the item condition. To the extent practical,
placards should be located adjacent to the control or indicator for the item affected; however, unless
otherwise specified (i.e. AFM), placard wording and location will be determined by the aircraft operator.

AIRCRAFT FAA MMEL Revision REVISION NO. DATE PAGE NO.

HS-125 Fleet Rev 8d Original 08/20/2016 1-7

24. Repair Category. All users of an MEL approved under parts 91K, 121, 125, 129, 135, and 142
must effect repairs of inoperative instrument and equipment items, deferred in accordance with the
MEL, at or prior to the repair times established by the following letter designators. Part 91 MEL users
(D095/D195 LOAs) are not required to comply with the repair categories, but will comply with any
provisos defining a repair interval (flights, flight legs, cycles, hours, etc):

A. Repair Category A. This category item must be repaired within the time interval specified in
the “Remarks or Exceptions” column of the aircraft operator’s approved MEL. For time intervals
specified in “calendar days” or “flight days”, the day the malfunction was recorded in the aircraft
maintenance record/logbook is excluded. For all other time intervals (i.e., flights, flight legs, cycles,
hors, etc.), repair tracking begins at the point when the malfunction is deferred in accordance with the
operator’s approved MEL.

B. Repair Category B. This category item must be repaired within 3 consecutive calendar-days
(72 hours) excluding the day the malfunction was recorded in the aircraft maintenance record/logbook.
For example, if it were recorded at 10 a.m. on January 26th, the 3-day interval would begin at midnight
the 26th and end at midnight the 29th.

C. Repair Category C. This category item must be repaired within 10 consecutive calendar-days
(240 hours) excluding the day the malfunction was recorded in the aircraft maintenance record/logbook.
For example, if it were recorded at 10 a.m. on January 26th, the 10-day interval would begin at midnight
the 26th and end at midnight February 5th.

D. Repair Category D. This category item must be repaired within 120 consecutive calendar-days
(2880 hours) excluding the day the malfunction was recorded in the aircraft maintenance
record/logbook.

25. Takeoff. Takeoff is the act of beginning a flight in which an aircraft is accelerated from a state of
rest to that of flight. For the purposes of MEL relief, this translates to the point at which the pilot
physically begins to apply power to initiate the takeoff from the runway or takeoff surface.

26. Triple Asterisk (***). Indicates an item which is not required by regulation but which may have
been installed on some models of aircraft covered by this MMEL. This item may be included on the
aircraft operator’s MEL after the approving office has determined that the item has been installed on
one or more of the aircraft operator’s aircraft. The symbol, however, must not be carried forward into
the aircraft operator’s MEL. It should be noted that neither this policy nor the use of this symbol
provides authority to install or remove an item from an aircraft.

27. Visible Moisture. An atmospheric environment containing water, in any form, that can be
seen in natural or artificial light; for example, clouds, fog, rain, sleet, hail, or snow.

28. Visual Flight Rules (VFR). VFR is as defined in 14 CFR Part 91. This precludes a pilot from filing
an Instrument Flight Rules (IFR) flight plan.

29. Visual Meteorological Conditions (VMC). VMC means the atmospheric environment is such that
would allow a flight to proceed under the visual flight rules applicable to the flight. This does not
preclude operating under Instrument Flight Rules.

30. (M). This symbol indicates a requirement for a specific maintenance procedure which must be
accomplished prior to operation with the listed item inoperative. Normally, these procedures are
accomplished by maintenance personnel; however, other personnel may be qualified and authorized to
perform certain functions. Procedures requiring specialized knowledge or skill, or requiring the use of
tools or test equipment, should be accomplished by maintenance personnel. The satisfactory
accomplishment of all maintenance procedures, regardless of who performs them, is the responsibility

Sundance Aviation MINIMUM EQUIPMENT LIST

AIRCRAFT FAA MMEL Revision REVISION NO. DATE PAGE NO.

HS-125 Fleet Rev 8d Original 08/20/2016 1-8

of the aircraft operator. Appropriate procedures are required to be produced as part of the aircraft
operator’s manual or MEL.

31. (O). This symbol indicates a requirement for a specific operations procedure which must be
accomplished in planning for and/or operating with the listed item inoperative. Normally, these
procedures are accomplished by the flightcrew; however, other personnel may be qualified and
authorized to perform certain functions. The satisfactory accomplishment of all procedures, regardless
of who performs them, is the responsibility of the aircraft operator. Appropriate procedures are required
to be produced as a part of the aircraft operator’s manual or MEL.

32. Electronic Fault Alerting System. New generation aircraft display system fault indications to the
flight crew by use of computerized display systems. Aircraft manufacturers incorporate individual
design philosophies when determining the data that is represented. The following are customized
definitions (specific to each manufacturer) to help determine the level of messages affecting the
aircraft's dispatch status.

Preamble
(Effective 6/14/89)

The following is applicable for authorized certificate holders operating under Title 14 Code of Federal
Regulations (14 CFR) Parts 121, 125, 129, 135: 14 CFR require that all equipment installed on an
aircraft in compliance with the Airworthiness Standards and the Operating Rules must be operative.
However, the Rules also permit the publication of a Minimum Equipment List (MEL) where compliance
with certain equipment requirements is not necessary in the interests of safety under all operating
conditions. Experience has shown that with the various levels of redundancy designed into aircraft,
operation of every system or installed component may not be necessary when the remaining operative
equipment can provide an acceptable level of safety.

A Master Minimum Equipment List (MMEL) is developed by the FAA, with participation by the aviation
industry, to improve aircraft utilization and thereby provide more convenient and economic air
transportation for the public. The FAA approved MMEL includes those items of equipment related to
airworthiness and operating regulations and other items of equipment which the Administrator finds
may be inoperative and yet maintain an acceptable level of safety by appropriate conditions and
limitations; it does not contain obviously required items such as wings, flaps, and rudders. The MMEL
is the basis for development of individual operator MELs which take into consideration the operator's
particular aircraft equipment configuration and operational conditions. Operator MELs, for
administrative control, may include items not contained in the MMEL; however, relief for administrative
control items must be approved by the Administrator. An operator's MEL may differ in format from the
MMEL, but cannot be less restrictive than the MMEL. The individual operator's MEL, when approved
and authorized, permits operation of the aircraft with inoperative equipment. Equipment not required by
the operation being conducted and equipment in excess of 14 CFR requirements are included in the
MEL with appropriate conditions and limitations. The MEL must not deviate from the Aircraft Flight
Manual Limitations, Emergency Procedures or with Airworthiness Directives. It is important to
remember that all equipment related to the airworthiness and the operating regulations of the aircraft
not listed on the MMEL must be operative.

Suitable conditions and limitations in the form of placards, maintenance procedures, crew operating
procedures and other restrictions as necessary are specified in the MEL to ensure that an acceptable
level of safety is maintained.

The MEL is intended to permit operation with inoperative items of equipment for a period of time until
repairs can be accomplished. It is important that repairs be accomplished at the earliest opportunity. In
order to maintain an acceptable level of safety and reliability the MMEL establishes limitations on the
duration of and conditions for operation with inoperative equipment.

The MEL provides for release of the aircraft for flight with inoperative equipment. When an item of
equipment is discovered to be inoperative, it is reported by making an entry in the Aircraft Maintenance
Record/Logbook as prescribed by 14 CFR. The item is then either repaired or may be deferred per the
MEL or other approved means acceptable to the Administrator prior to further operation. MEL
conditions and limitations, do not relieve the operator from determining that the aircraft is in condition
for safe operation with items of equipment inoperative. When these requirements are met, an
Airworthiness Release, Aircraft Maintenance Record/Logbook entry, or other approved documentation
is issued as prescribed by 14 CFR. Such documentation is required prior to operation with any item of
equipment inoperative.

AIRCRAFT FAA MMEL Revision REVISION NO. DATE PAGE NO.

HS-125 Fleet Rev 8d Original 08/20/2016 1-10

Operators are responsible for exercising the necessary operational control to ensure that an acceptable
level of safety is maintained. When operating with multiple inoperative items, the interrelationships
between those items and the effect on aircraft operation and crew workload will be considered.
Operators are to establish a controlled and sound repair program including the parts, personnel,
facilities,
procedures and schedules to ensure timely repair.

WHEN USING THE MEL, COMPLIANCE WITH THE STATED INTENT OF THE PREAMBLE,
DEFINITIONS, AND THE CONDITIONS AND LIMITATIONS SPECIFIED IN THE MEL IS REQUIRED.

Each Flight Operations Evaluation Board (FOEB) Chairman should apply this Policy to affected MMELs
through the normal FOEB process.
