AIRBUS INDUSTRIE
A310 and A300-600 Aircraft
1. APPLICABILITY:
AIRBUS INDUSTRIE A310 and A300-600 aircraft, all certified models and all serial numbers, except for :
- aircraft on which AIRBUS INDUSTRIE serial modification No.11874 has been embodied, or,
-aircraft on which AIRBUS INDUSTRIE Service Bulletin A310-27-2087 or A300-27-6042 has been embodied.
2. REASON :
In order to prevent any interference between the 408VU panel and the rudder trim control knob, which could prevent the self-recentering of the switch to the neutral position when released, thus causing a rudder movement up to the maximum trim deflection, and which could lead to critical flight situations, the application of AIRBUS INDUSTRIE modification No. 11662 (Service Bulletin A310-27-2084 or A300-27-6037) was rendered mandatory by Airworthiness Directive 97-111-219(B).
However, cases of insufficient clearance between the 408VU panel and the rudder trim control knob have been observed on aircraft which had already been modified according to the instructions of AIRBUS INDUSTRIE Service Bulletin A310-27-2084 or A300-27-6037.
3. ACTIONS:
Before October 30, 1999, replace the rudder trim control knob in accordance with the instructions of AIRBUS INDUSTRIE Service Bulletin A310-27-2087 or A300-27-6042.
