EASA AD 2023-0206: Master Minimum Equipment List — Amendment

What to do

Operators of Airbus A330 and A340 aircraft must implement the MMEL update within 30 days of the directive's effective date if their aircraft have the specified Airbus modifications installed. For aircraft without these modifications, they may be upgraded to comply by installing the modification and then applying the MMEL update before the next flight. The applicable Minimum Equipment Lists must be amended and operations conducted in accordance with the updated MMEL.

Summary

EASA Airworthiness Directive 2023-0206 is an amendment addressing the Master Minimum Equipment List (MMEL) for Airbus A330 and A340 aeroplanes. It applies to multiple variants of these aircraft and mandates updates to the MMEL related to fuel quantity indication items. The directive ensures continued airworthiness by requiring operators to comply with revised MMEL provisions.

What changed

This amendment introduces an update to the Airbus A330/A340 MMEL, specifically revising items related to inner, outer, trim, center, and RCT fuel quantity indications on the FUEL SD page. It prohibits Required Navigation Performance - Authorization Required (RNP-AR) operations when certain MMEL items are in effect and requires operators to amend their Minimum Equipment Lists accordingly. The update applies differently to aircraft with or without specific Airbus modifications installed.

Why it matters

This directive addresses a safety issue where dispatching aircraft under certain MMEL fuel quantity indication items can cause temporary loss of Flight Director and Auto Throttle functions, potentially affecting flight path control during critical phases. For operators and maintenance teams, compliance ensures safe navigation capabilities and adherence to regulatory requirements. It also impacts operational planning by restricting RNP-AR operations under specified conditions.
