Airbus A320 MEL Items - AviationHunt

Minimum Equipment List (MEL)

The Minimum Equipment List (MEL) is based on the Master Minimum Equipment List (MMEL). The MEL may differ in format from the MMEL, but will not be less restrictive than the MMEL. The MEL shall not deviate from any applicable Airworthiness Directive or any other Mandatory Requirement.

MEL Sections

A320 Aircraft MEL has four sections:

How to Use (HOW) : This section contains general information and describes the organization of the manual.
MEL Entries (ME) : This section lists all the ECAM alerts and indicates the associated MEL item (if any) to apply for dispatching the aircraft.
MEL Items (MI) : This section is approved by the EASA and lists all the MEL items with the associated dispatch conditions.
MEL Operational Procedures (MO) : This section gives the operational procedures that are associated with the MEL items.

Note: The MEL Maintenance Procedures are published in the AMM.

The A320 Family aircraft is equipped with the Electronic Centralized Aircraft Monitoring (ECAM) which provides different levels of aircraft systems monitoring messages:

ECAM warning
ECAM advisor
ECAM caution
ECAM memo

ECAM warning and ECAM caution messages are listed in the “MEL Entries” section. ECAM advisory and ECAM memo messages are not listed in the “MEL Entries”.

MEL Entries (ME) section lists all the ECAM alerts and indicates the associated MEL item (if any) to apply for dispatching the aircraft. This section is a user-friendly entry point for the flight crew and the maintenance personnel when an ECAM alert reports a system failure.
