No person may operate an aircraft to which an Airworthiness Directive applies,
except in accordance with the requirements of that Airworthiness Directive,
unless otherwise agreed with the Authority of the State of Registry.
Corresponding foreign Airworthiness Directive(s):
Not applicable
Airworthiness Directive(s) replaced:
None
Person in charge of airworthiness:
AIRBUS SAS
Type certificate(s) No. 180
TCDS No 180
Type(s):
A320 aircraft
ATA chapter:
27
Subject:
Flight controls - ELAC 1 computer
1. EFFECTIVITY:
AIRBUS A320 all certified models, all manufactured serial numbers, except aircraft that have received
AIRBUS modification 33317 in production or AIRBUS Service Bulletin A320-27-1149 in service.
2. REASONS:
During investigations on A320, a critical flight phase has been evidenced.
In the case the aircraft is under MMEL with ELAC 1 (Elevator and Aileron Computer) inoperative or
ELAC 1 PITCH FAULT cautions displayed, the loss of SEC 1 (Spoiler and Elevator Computer) in descent
when speed brakes are deflected will lead to:
- the automatic retraction of speed brakes 3 and 4,
- the loss of the double hydraulic pressurisation on elevators.
In manual mode and at high speed, the retraction of speed brakes 3 and 4 from their full extended position
will induce a pitch down effect that cannot be counteracted by the elevator controlled by a single actuator.
The aircraft pitches down and accelerates.
For this reason, this Airworthiness Directive (AD) renders mandatory an operational limitation.
3. MANDATORY ACTIONS AND COMPLIANCE TIMES:
From the effective date of this AD, apply the following:
Insert in the Minimum Equipment List (MEL) of the aircraft, the Temporary Revision (TR) TR
No 01-27/01H issue 01 of the Master Minimum Equipment List (MMEL) A318/A319/A320/A321 that
introduces the operational limitation “Above FL 200, the use of speed brakes lever is limited to its half
position” when the aircraft is under MMEL ELAC 1, and apply this procedure.
