Bell Helicopter 212, 412 Series8 May 2008JOINT AVIATION AUTHORITIESMASTER MINIMUM EQUIPMENT LISTExport Classification: C, ECCN 9E991JOINT AVIATION AUTHORITIES212, 412 SERIES Master Minimum Equipment List (MMEL)PREAMBLEThe following is applicable for authorized certificate holders operating under Authorities OperatingRequirements (JAR-OPS). The JAR require that all equipment installed on an aircraft in compliance with theAirworthiness Standards and the Operational Requirements must be operative. However, the requirements alsopermit the publication of a Minimum Equipment List (MEL) where compliance with certain equipmentrequirements is not necessary in the interest of safety under all operating conditions. Experience has shown thatwith the various levels of redundancy designed into aircraft, operation of every system installed or componentmay not be necessary when the remaining operative equipment can provide an acceptable level of safety.The Master Minimum Equipment List (MMEL) is developed by the Type Certificate Holder and recommendedfor approval by the OEB to the JAA Member Authorities to improve aircraft utilization and thereby providemore convenient and economic air transportation for the public. The JAA MMEL includes those items ofequipment related to airworthiness and Operational Requirements and other items of equipment which JAAfinds may be inoperative and yet maintain an acceptable level of safety by appropriate conditions andlimitations; it does not contain obviously required items such as rotor blades, stabilizer and engines.The MMEL Is the basis for development of individual operator’s MELs which take into consideration theoperator’s particular aircraft equipment configuration and operational conditions. An operator’s MEL maydiffer in format from the MMEL, but cannot be less restrictive than the MMEL. The individual operator’sMEL, when approved permits operation of the aircraft with inoperative equipment.Equipment not required by the operation being conducted and equipment in excess of EASA requirements areincluded in the MEL with appropriate conditions and limitations. The ME must not deviate from AirworthinessDirectives or any other Mandatory Requirement. It is important to remember that all equipment related to theairworthiness and the Operational Requirements of the aircraft not listed on the MMEL must be operative.Suitable conditions and limitations in the form of placards, maintenance procedures, crew operating proceduresand other restrictions as necessary are specified in the MEL to ensure that an acceptable level of safety ismaintained.The MEL is intended to permit operation with inoperative items of equipment for a period of time untilrectification’s can be accomplished. It is important that rectifications be accomplished at the earliestopportunity. In order to maintain an acceptable level of safety and reliability the MMEL establishes limitationon the duration of and conditions for operation with inoperative equipment. The MEL provides for release ofthe 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 AircraftMaintenance Record/Logbook as prescribed by JAR. The item is then either rectified or may be deferred perthe MEL or other approval means acceptable to the competent Authority prior to further operation. MELconditions and limitation do not relieve the operator from determining that the aircraft is in a condition for safeoperation with items of equipment inoperative.When these requirements are met, an Airworthiness1Release, Aircraft Maintenance Record/Logbook entry,Use or disclosure of data contained on this sheet is subject to the restriction on the title page of this document.

Bell Helicopter 212, 412 Series8 May 2008JOINT AVIATION AUTHORITIESMASTER MINIMUM EQUIPMENT LISTExport Classification: C, ECCN 9E991or other approved documentation is issued as prescribed by JAR. Such documentation is required prior tooperation with any item of equipment inoperative.Operators are responsible for exercising the necessary operational control to ensure that an acceptable level ofsafety is maintained. The exposure to additional failures during continued operation with inoperative system orcomponents must also be considered. Wherever possible account has been taken in this MMEL of multipleinoperative items. However, it is unlikely that all possible combinations of this nature have been accounted for.Therefore, when operating with multiple inoperative items, the inter-relationships between those items and theeffect on aircraft operation and crew workload must be considered.Operators are to establish a controlled and sound rectification program including the parts, personnel, facilities,procedures and schedules to ensure timely rectification. This program should identify the actions required forMaintenance discrepancy messages.WHEN USING THE MEL, COMPLIANCE WITH THE STATED INTENT OF THE PREAMBLE,DEFINITIONS AND THE CONDITIONS AND LIMITATIONS SPECIFIED IN THE MEL IS REQUIRED.2Use or disclosure of data contained on this sheet is subject to the restriction on the title page of this document.

Bell Helicopter 212, 412 Series8 May 2008JOINT AVIATION AUTHORITIESMASTER MINIMUM EQUIPMENT LISTExport Classification: C, ECCN 9E991DEFINITIONS AND EXPLANATORY NOTESThe definition(s) presented here are additional to any which are otherwise applicable:System Definitions.1) In this list, the items of equipment are classified in systems according to the ATA 100 specification.Individual items within a given ATA classification are numbered sequentially.2) "Item" (Column 1) means the equipment, system, component, or function listed in the "Item" column.3) “(if installed)”: Indicates the listed item of equipment is not applicable to all models or configurations. Itdoes not imply that the aircraft may be operated in accordance with this MMEL with the item removed.4) Items annotated in UPPER CASE letters indicate the precise flight deck legend used.5)“Rectification Intervals” (column 2): the following definitions are used throughout this document:Category A. Items in this category shall be rectified in accordance with the conditions stated in theRemarks column (5) of the MMEL.Category B. Items in this category shall be repaired within three (3) consecutive calendar days (72hours); excluding the day the malfunction was recorded in the aircraft maintenance record/logbook. Forexample, if it were recorded at 10 a.m. on January 26th, the three day interval would begin at midnightthe 26th and end at midnight the 29th.Category C. Items in this category shall be repaired within ten (10) consecutive calendar days (240hours); excluding the day the malfunction was recorded in the aircraft maintenance record/logbook. Forexample, if it were recorded at 10 a.m. on January 26th, the 10 day interval would begin at midnight the26th and end at midnight February 5th.Category D. Items in this category shall be repaired within one hundred and twenty (120) consecutivecalendar days (2880 hours); excluding the day the malfunction was recorded in the aircraft maintenancelog and/or record.6) "Number Installed" (Column 3) is the number (quantity) of items normally installed in the aircraft.
