APPLICABILITY:

AIRBUS INDUSTRIE all model aircraft (300, 310, 300-600, 300-600ST, 319, 320, 321, 330, 340) equipped with powered cockpit seats manufactured by SOGERMA with :

- Part Number (P/N) TAAI2-13PE00-01, TAAI2-13PE01-01, TAAI2-33PE00-01, TAAI2-33PE01-01 for Captain seats, and

- P/N TAAI2-13CE00-01, TAAI2-13CE01-01, TAAI2-33CE00-01, TAAI2-33CE01-01 for First Officer seats

and fitted with P/N 4136290003 LABINAL actuator.

Note 1: The involved seats have serial number below S/N 657.

Note 2: Such equipped seats are identified by a label close to the identification plate with "Seat equipped with "LABINAL" actuator" printed on it and without any P/N indication.

REASONS:

Operators reported some uncommanded horizontal movement of cockpit seat adjustment during flight. Investigation revealed that these events were due to broken LABINAL actuator electrical brake.

If left uncorrected, this failure can lead to untimely seat movement or loss of the seats brake function (seat becoming "free").

ACTIONS:

The following measures are rendered mandatory from the effective date of this Airworthiness Directive (AD).

Within six months from the effective date of this AD, remove P/N 4136290003 LABINAL actuators and replace them by P/N 4136290004 or 4136290005 LABINAL actuators or P/N 6147-6 AVIAC actuators in accordance with SOGERMA Service Bulletin TAAI2-25-402 at Revision 1 of dated December 27, 2000.
