AIRWORTHINESS DIRECTIVE
The following airworthiness directive (AD) may be applicable to an aircraft which our records indicate is registered in your name. ADs are issued pursuant to Canadian
Aviation Regulation (CAR) 521 Division X. Pursuant to CAR 605.84 and the further details of CAR Standard 625, Appendix H, the continuing airworthiness of a Canadian
registered aircraft is contingent upon compliance with all applicable ADs. Failure to comply with the requirements of an AD may invalidate the flight authorization of the aircraft.
Alternative means of compliance shall be applied for in accordance with CAR 605.84 and the above-referenced Standard.
This AD has been issued by the Continuing Airworthiness Division (AARDG), National Aircraft Certification Branch, Transport Canada, Ottawa, telephone 613 952-4357.
Number:
CF- 2011-20
Subject:
Power Lever Assembly – Fouling of the United Kingdom Civil Aviation Authority
Flight Idle Gate
Effective:
28 July 2011
Applicability:
Bombardier Inc. DHC-8 Aeroplane Models 102, 103, 106, 201, 202, 301, 311, 314 and
315 Serial Numbers 021 through 661 that have a United Kingdom Civil Aviation
Authority (U.K. CAA) Flight Idle Gate option Bombardier (de Havilland) Customer
Request CR873SO8112, CR873CH00003 or CR873CH00005 installed.
Compliance:
As indicated below, unless already accomplished.
Background:
An operator of a DHC-8 aeroplane retrofitted with the U.K. CAA Flight Idle Gate option
has reported that both power lever assemblies (PLA) jammed at the flight idle position
when the aeroplane was ready for take-off. Post event inspection revealed the flight idle
gates were jammed in the raised position with their vertical stop face wedged against the
protruding shop head of a rivet located on the underside of the center console cover
assembly. This fouling condition may prevent the pilot from selecting a PLA position
forward of FLT IDLE from a previously selected position aft of FLT IDLE, which can result
in the inability to advance the PLA to achieve take-off power. Inability to achieve take-off
power can prevent the aeroplane to perform a go around manoeuvre post touchdown,
which may result in an unsafe condition.
Bombardier has issued Service Bulletin (SB) 8-76-31 to replace six existing rivets (each
with a protruding shop head) on the center console cover assembly to eliminate potential
fouling condition of the PLA assembly. This directive mandates the incorporation of
SB 8-76-31.
Corrective
Actions:
Within 2000 hours air time or 24 months after the effective date of this directive,
whichever occurs first, identify and replace the six affected rivets on the center console
cover assembly (part number (P/N) 87610180) and complete all required actions in
accordance with Bombardier SB 8-76-31 dated 03 February 2011, or later revisions
approved by the Chief, Continuing Airworthiness, Transport Canada.

For the Minister of Transport, Infrastructure and Communities
