Plain English Summary

3/10 complexity

This Airworthiness Directive requires installation of elevator surface dampers on all BAe 146 and Avro 146‑RJ series aircraft, carried out to BAE Systems Mandatory Service Bulletin 27-169-01692A Revision 1. Operators or their maintenance organisations must complete the work during the next ‘C’ check or the first maintenance period exceeding three consecutive days after 3 October 2002, and no later than 31 January 2004 (Requirement; Compliance). It creates a mandatory maintenance obligation, associated downtime and direct cost for aircraft operators.

Amdt 1

Elevator Surface Flight Damper 10/2002

Applicability: All BAe 146 Series aircraft.

All Avro 146-RJ Series aircraft.

Requirement: Action in accordance with BAE Systems Mandatory Service Bulletin 27-169-01692A Revision 1.

Compliance: During the next ‘C’ check or maintenance period which is planned to exceed 3 consecutive calendar days after 3 October 2002, whichever occurs first; but not later than 31 January 2004.

This Amendment becomes effective on 3 October 2002.

Background: During certain atmospheric conditions, elevator stability can be reduced by the formation of ice on the elevator servo tab. This can result in a phenomenon known as ‘pitch oscillation’. Elevator surface dampers address this by providing additional damping directly to the elevator, thus suppressing the oscillation. This Directive requires installation of elevator surface dampers.

Amendment 1 is issued in response to a revision of the Requirement document, which deleted reference to dependant modifications and changed the compliance time.

The original issue of this Airworthiness Directive became effective on 13 June 2002.
