Plain English Summary

3/10 complexity

Requires Airbus A319/A320/A321 aircraft (those without Mod 28909 or without SB A320-27-1130 embodied) to have the autopilot-mode engagement/disengagement lever modified per Airbus SB A320-27-1130 (Revision 1). Operators must complete the modification by 30 June 2002. CASA issued the AD after reports that a jamming disengagement lever could leave artificial feel in AP mode and cause stiff rudder pedals, reducing control on approach and landing. The compliance cost, parts and downtime fall to aircraft operators who must follow the manufacturer’s instructions (Requirement; Compliance).

AD/A320/99

Amdt 2

Rudder Pedals 3/2001

Applicability: All Model A319, A320 or A321 aircraft without Airbus Industrie Modification 28909 installed at production or Airbus Industrie Service Bulletin (SB) A320-27-1130 or SB A320-27-1130 Revision 1 in-service.

Requirement: Modify the AP-Mode engagement/disengagement lever in accordance with Airbus Industrie SB A320-27-1130 or SB A320-27-1130 Revision 1.

Note: DGAC AD 2000-372-151(B) refers.

Compliance: Before 30 June 2002, unless already accomplished.

This amendment becomes effective on 22 March 2001.

Background: The manufacturer received several reports of cases of stiff rudder pedals which could reduce aircraft control during approach and landing phases, with a risk of the aircraft leaving the runway. The rudder pedal stiffness was found to be due to artificial feel being in autopilot mode while the autopilot is disengaged; caused by jamming of the artificial feel AP-Mode disengagement lever.

Amendment 1 introduced another modification as new cases of stiff rudder pedals were reported after embodiment of the previously required modification.

Amendment 2 is issued to introduce Revision 1 of the Requirement document which clarifies the Accomplishment Instructions.

The original issue of this Directive became effective on 17 June 1999.

Amendment 1 of this Airworthiness Directive became effective on 2 November 2000.
