D2/2011L/S2 Amendation of the Airbus OEB

Justification of the recommendation

The aircraft manufacturer's Operations Engineering Bulletin (OEB) contains flight crew procedures for a bleed air system fault if one or both systems fail. It contains the instructions for reducing stress to the single operative system by means of actions prior to the departure as well as those for the procedure during an in-flight failure.

Recommendation

The Safety Investigation Authority, Finland recommends that the EASA oblige Airbus S.A.S. to amend the OEB in a manner that clearly segregates the procedures for prior to the flight and during the flight. Additionally Airbus S.A.S. needs to assure that all the appropriate actions included in the OEB are in line with QRH.
