AIRBUS INDUSTRIE

A310 aircraft

Slat and flap power control units - Life limit of the Pressure-Off Brakes (POBs) (ATA 27)

APPLICABILITY:

AIRBUS INDUSTRIE A310 aircraft, all certified models and all serial numbers.

REASONS:

In the context of the program aiming at controlling life limited equipment, AIRBUS INDUSTRIE found that some Pressure-Off Brakes (POBs) installed on the Power Control Units (PCUs) of the slats and flaps have been operated beyond the allowable life limit of 12,000 flights.

It is thus necessary to remove all POBs which might have exceeded this limit.

ACTIONS:

Within 16 months following the effective date of this Airworthiness Directive, unless already accomplished, check the serial number of the POBs installed on the Power Control Units (PCUs) of the slats and flaps (positions 1 and 2), remove and replace any POB operated beyond the allowable life limit, in accordance with the instructions of AIRBUS INDUSTRIE Service Bulletin A310-27-2096.

(any later approved revision of this SB is acceptable).
