Plain English Summary

3/10 complexity

Requires Airbus A319/A320/A321 operators to modify the parking-brake system in accordance with Airbus Service Bulletin A320-32-1201 Rev 1 (or later), except aircraft with Airbus Mod 30062 or that already embody the SB. CASA (the delegate) sets a compliance deadline (no later than 31 March 2009). Operators/owners must arrange and pay for the modification and any downtime. The change aims to prevent loss of parking-brake braking that, if not corrected or if crew procedures are not followed, can lead to runway excursions.

AD/A320/165 Parking Brake 1/2005

Applicability: All Airbus A319, A320 and A321 aeroplanes except those that have Airbus Mod 30062 incorporated during production or Airbus Service Bulletin (SB) A320-32-1201 Rev 1 incorporated in service.

Requirement: Modify the park brake system in accordance with the accomplishment instructions given in Airbus SB A320-32-1201 Rev 1 or later approved revision.

Note: DGAC AD F-2004-137 and EASA Approval 2004-10839 refer.

Compliance: No later than 31 March 2009.

This Airworthiness Directive becomes effective on 20 January 2005.

Background: Airbus reported that an operator experienced a loss of parking brake whilst at the holding point of the runway awaiting take-off. This lead to a runway excursion.

Analysis showed that, as per design, when the parking brake is selected, braking through the pedals is inhibited. A FCOM procedure recommends that in the case of park brake loss the parking brake handle is immediately released to restore braking to the pedals. If this procedure is not followed a situation could develop that would have hazardous consequences. This Directive mandates the modification of the park brake system to prevent such an occurrence.
