(REMARKS OR EXCEPTION)

Column 1 : System and sequence numbers - Item

Identifies the system by ATA classification and the item. It indicates the equipment, systems, components

for which dispatch conditions apply. An “_{if installed}” annotation indicates that the listed item is not

applicable to all models or configurations. It does not imply that the aircraft may be operated, in

accordance with the MMEL, with the item removed, unless clearly indicated in the associated REMARKS or CONDITIONS column (5) of the MMEL.

Column 2 : Rectification interval

For each applicable item, the rectification interval column indicates the rectification interval category. Each category is defined according to the following JAR-MMEL/MEL definitions:

Category A

No standard time interval is specified, however, items in this category shall be repaired in accordance with the conditions stated in REMARKS OR CONDITIONS (5) of the MMEL. (i) Where a time period is specified in calendar days it shall start at 00:01 on the calendar day following the day of discovery.

(ii) Where a time period is specified in number of flight or flight hours, it shall start at the beginning of the next flight that follows the discovery.

- Category B

Items in this category shall be repaired within three (3) consecutive calendar days, excluding the

day of discovery. For example, if it was recorded at 10 a.m. on January 26th, the three-day interval

begins at midnight on January 26th, and ends at midnight the January 29th.

- Category C

Items in this category shall be repaired within ten (10) consecutive calendar days (240 hours), excluding the day of discovery.

- Category D

Items in this category shall be repaired within one hundred and twenty (120) consecutive calendar days, excluding the day of discovery.

- Dash symbol “-”

A dash symbol may appear in Column 2, associated with the annotation “As required by National Authorities” in Column 5, to indicate that the rectification interval category is not known, because it depends on national regulations.

“Repair Interval Extension” If, in an exceptional case, a repair category B or C item can not be

accomplished within the given repair interval, UNI AIRWAYS is authorized to give one time extension

under the accepted procedure in GMM 4.14 by CAA. Otherwise shall get the permission of the extension

from CAA. The permission of extension has to be documented in the Aircraft Technical Log Book with the

permission form. UNI AIRWAYS is not authorized to extend A and D items in the MEL. Misuse of the MEL

extension authority may result in UNI AIRWAYS OpSpecs being amended by removing the authority for

UNI AIRWAYS to use the MEL extension authority and/or use an MEL.

Column 3 : Number installed

Shows the number of installed components, it matches with the type-certificated configuration of the aircraft.

- Dash “-” indicates a variable quantity installed on the aircraft.

Column 4 : Number required for dispatch

Shows the minimum quantity of components which must be operative for a MMEL dispatch, under the conditions listed in Column 5 (if any).

- Dash “-” indicates a variable quantity, minimal required for the dispatchability of the aircraft.

Column 5 : Remarks or exceptions

Gives remarks or conditions linked to a MMEL dispatch. It indicates the suitable conditions and limitations in the form of placard, maintenance procedures, operational procedures and dispatch conditions as necessary to ensure that an acceptable level of safety is maintained.

- Asterisk “*” in column 5 requires inoperative components to be clearly placarded in the cockpit. - Operational and Maintenance Procedures:

An inoperative equipment may refer to an operational (o) and/or maintenance procedure (m) in the

Dispatch Deviation Guide (DDG), to ensure an acceptable level of safety.

It is the operator’s responsibility to ensure that all the (o) and/or (m) refer to an appropriate operational and/or maintenance procedure, or to a procedure established by the operator and accepted by the National Authority. Then the operator must ensure that these procedures are appropriately applied.

Both (o) and (m) identifiers used singularly or in conjunction with each other, require that appropriate procedures be established, published and complied with if flight is accomplished with the item inoperative.

Task mark (o) in column 5 identifies an operational procedure when operating with the associated

inoperative item. Operational procedures may require crew actions, limitations, performance penalties or crew awareness information to be taken into account.

These procedures are normally carried out by qualified flight or cabin crew, but may be accomplished by other qualified, approved personnel. However the flight crew must always be informed of the applicable operational procedure prior to each flight under associated MMEL item.

When flight situation occurs the operational procedures must always be applied under the associated item (unless its periodicity of application is clearly specified in Column 5)

Maintenance Procedures

Task mark (m) in column 5 identifies a maintenance procedure.These procedures are normally carried

out by maintenance personnel, but some elementary maintenance tasks may be accomplished by crew members or other qualified, approved personnel. Flight crew can accomplish some of these elementary (m) procedures but it remains the responsibility of the operator and under its national authority approval.

However it is recommended that maintenance personnel accomplish procedures that require specialized knowledge, skills, or the use of tools and test equipment. The maintenance procedures must always be performed one time before the flight under the associated item and, if applicable, must be repeated at the interval specified in the Column5

- Different exceptions may be required for dispatch. They will be separated by “- OR -“ and identified by (1), (2), (3) in column 1.

References

- Another source of information must be reviewed and associated restrictions, and/or procedures must be applied (e.g. “Refer to AFM…”).

- Another ATA chapter of the MMEL must be reviewed, in order to determine the applicable item. The repair interval category the most restrictive must be applied.

- References are introduced to assist the Operator in complying with MMEL requirements. However, as

indicated in the PREAMBLE, the Operator is still responsible for determining the applicable

interrelationships and associated requirements. 2. DEFINITIONS

- Inoperative: any time a system and/or component malfunctions to the extent that it does not accomplish its intended purpose and/or is not consistently functioning within its designed operating limit(s) or tolerance(s).

- Considered Inoperative: must be treated as “inoperative”. Therefore the “considered inoperative” MMEL item must also be recorded in the Technical log and the associated dispatch exceptions must be applied, in addition to any applicable (o) and (m) procedure. The shorter rectification interval, between the initial inoperative item and the “considered inoperative” item, should be applied. - Day of discovery: The calendar day that the failure has been recorded in the aircraft maintenance record/logbook.

- As required by regulation: The listed item must comply with applicable operational regulation. Operators may refer to the ATC regulation, and/or some local (airport) regulation.

- ETOPS: refers to operation according to ”Extended Range operations of twin engine airplanes” requirements.

Refer to the appropriate customised AFM.

- Extended overwater flight: Refer to Annex 3 of the European Council Regulation n°3922/91, §1.830 - Flight: is defined as the period of time that begins the moment at which an aircraft begins to move by its own means in preparation for take off, continues during take off and the applicable flight phases, and ends when the aircraft lands and comes to a complete stop in its parking area.

- Ferry Flight: non-revenue flight with necessary flight crewmember to conduct a ferry flight. - Calendar days: Some MMEL items are assigned a time interval in “days” in REMARKS OR CONDITIONS column 5. “Days” must be considered as “calendar days”, not including the calendar day that the failure was recorded.

- VMC flight conditions: atmospheric environment allows the flight to proceed under the Visual Meteorological Conditions applicable to the flight.

- Icing conditions: Visible moisture in any form is present, and OAT on ground and for take off is at or below 5° or when TAT in flight is at or below 7° . Refer to the AFM 2-06.

- Cargo configuration: refers to cargo operations when aircraft is operated with an ATR cargo installation. In case of STC (Supplemental Type Certificate) installation, operator shall adapt its MEL with STC supplement.

(14)

ATR 72-600 MEL

DATE : SEP 15, 2012 REVISION:0.0 PAGE: 2-01-4 - Inflammable or Combustible material: material that can catch fire and burn. Where loading of

inflammable or combustible material is prohibited, no material may be loaded except the following: cargo handling equipment, flyaway kits (excluding e.g. cans of hydraulic fluid, cleaning solvents, batteries, chemical generators, etc) and in-flight service material (return catering-only closed catering trolleys/boxes, no newspaper, no alcohol or duty free goods).

CAT 2 Automatic approach: The required equipment are listed in the AFM 7-01.03

-Airplane Flight Manual (AFM) is the document required for type certification and approved by the responsible EASA Aircraft Certification Office. The EASA approved AFM for the specific aircraft is listed on the applicable Type Certificate Data Sheet.

-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.

-Flight Day means a 24 hour period (from midnight to midnight) either Universal Coordinated Time (UCT) or

local time, as established by the operator, during which at least one flight is initiated for the affected aircraft.

-Icing Conditions means an atmospheric environment that may cause ice to form on the aircraft or in the

engine(s).

-NOTE provides the useful information for crewmember / dispatcher / maintenance consideration.

Notes are used to identify applicable material which is intended to assist with compliance, but do not

relieve the operator of the responsibility for compliance with all applicable requirements. Notes are not

a part of the provisos.

"OPERATIONS NOTE" provides additional reminder for the crew/dispatcher.

"MAINTENANCE NOTE" provides additional reminder for the maintenance.

-Inoperative components of an inoperative system: Inoperative items which are components of a

system which 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).

-Deactivated and "Secured" means that the specified component must be put into an acceptable

condition for safe flight. An acceptable method of securing or deactivating will be established by the

operator.

-Considered inoperative means that the item of equipment must be treated as inoperative. For example,

MEL 36-11-03B states that Both Air Conditioning System is considered inoperative and therefore MEL

21-51-01B must be applied. Therefore, the Considered inoperative item must also be entered and the

associated dispatch conditions must be applied, including the respective O and M procedures if any. The

shorter rectification interval between the initial inoperative item and the “considered inoperative”

should be applied.

-Is not used in the provisos, remarks or exceptions for an MEL item may specify that another item

relieved in the MEL “is not used.” In such cases, crewmembers should not activate, actuate, or otherwise

utilize that component or system under normal operations. It is not necessary for the operators to

accomplish the (M) procedures associated with the item. However, operational requirements must be

(15)

ATR 72-600 MEL

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 to inform crewmembers that a component or system is not to

be used under normal operations.

-Inoperative means 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) or

tolerance(s).

-Visual Flight Rules (VFR) is as defined in FAR Part 91. This precludes a pilot from filing an Instrument

Flight Rules (IFR) flight plan.

-Visual Meteorological Conditions (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.

-Visible Moisture means 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.

-Day of Discovery is the calendar day an equipment/instrument malfunction was recorded in the aircraft

maintenance log and or record. This day is excluded from the calendar days or flight days specified by the

MMEL for the repair of an inoperative item of equipment. This provision is applicable to all MMEL items,

i.e., categories "A, B, C, and D".

-"" Single pointer index symbol in the column 1 indicates when MEL is initiating, FCD must be

informed by maintenance as early as possible but no later than dispatch.

-"" Double pointer index symbol in the column 1 indicates

1. When MEL is initiating, FCD must be informed by maintenance as early as possible

but no later than dispatch

2. Whatever MEL is initiating or existing, station manager or relative station department

must be informed by station maintenance as early as possible but no later than

dispatch.

-Each MEL item may provide more than one set of proviso. If more than one proviso is presented, only

one set of proviso can be chosen to configure the airplane for dispatch.

3. PREAMBLE

The following is applicable for authorized certificate holders operating under Federal Aviation

Regulations (FAR) Parts 121, 125, 129, 135: The FAR require that all equipment installed on an aircraft in

compliance with the Airworthiness Standard and the Operating Rules must be operative. However, the

Rulers 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

EASA, with participation by the aviation industry, to improve aircraft utilization and thereby provide

more convenient and economic air transportation for the public. The EASA 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 of

equipment 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 item 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 FAR 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 report by making an entry in the Aircraft Maintenance Record/Logbook as prescribed by

FAR. 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

(17)

ATR 72-600 MEL

When these requirements are met, an Airworthiness Release, Aircraft Maintenance Record/Logbook

entry, or other approved documentation is issued as prescribed by FAR. Such documentation is required

prior to operation with any item of equipment inoperative.

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.
