PREAMBLE 1. GENERAL
1.1 The PCAA Rules 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 interest 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/DGAC or the Regulatory Body of
the country of origin of the subject aircraft, with participation by the aviation industry, to improve aircraft utilization and thereby provide more convenient and economic air transportation for the
public. This approved MMEL will include those items of equipment related to Airworthiness and operating regulations and other items
of equipment which the regulatory body 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’s MEL, which takes 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 DG PCAA. An operator’s MEL may differ in format
from the MMEL, but cannot be less restrictive than the MMEL. Based on the respective aircraft configuration, the operator will develops its own MEL and submit the same to DG PCAA for
approval together with the MMEL of the aircraft type. The individual operator’s MEL, when approved and authorized, permits operation
of the aircraft with inoperative equipment covered by the MEL. 1.2 Equipment not required by the operation being conducted and
equipment in excess of PCAA requirements are included in the MEL with appropriate conditions and limitations. The exposure to
additional failures during continued operation with an operative system or component must also be considered in determining that
an acceptable level of safety is being maintained. The MEL must not deviate from the Aircraft Flight Manual Limitations, Emergency Procedures or with Airworthiness Directives. It is important to
remember that all equipments 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.
Minimum Equipment List
JUN/2020
Page 2 of 9 Operations Engineering
1.3 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 / Technical Log. The item is then either
repaired or may be deferred as per the MEL. 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.
1.4 When these requirements are met, an Airworthiness Release, Aircraft Maintenance Record/Logbook entry, or other approved
documentation is issued. 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.
1.5 Dispatch/Release of airplane with more than one item unserviceable is not allowed if a simultaneous change in operating
procedure for more than one major aircraft system would be necessary e.g. faults which require a change in electrical system operation and in hydraulic system operation would not be
simultaneously permissible. Dispatch/Release of airplane with more than one part missing from any one system is not allowed unless
specifically indicated in DDG/DDPG/CDL. Parts from different systems may be missing simultaneously, unless otherwise specified provided the limitation imposed by para 1.4 is not violated.
WHENEVER DOUBT EXISTS TO DISPATCH OR NOT, contact Chief Pilot Technical (Operations) and Chief Engineer Quality Assurance
or their representatives for advice on telephone at Karachi. 1.6 WHEN USING THE MEL, COMPLIANCE WITH THE STATED INTENT
OF THE PREAMBLE, DEFINITIONS, THE CONDITIONS AND LIMITATIONS SPECIFIED IN THE MEL IS REQUIRED. Definitions of
various symbols, abbreviations etc. used in the MEL format is to be in line (with required approved alterations) with the Definitions as given in the FAA / DGAC – Master Minimum Equipment List copy of
which is attached as Annexure-1 to this Preamble.
