Ad/Dart/5 - Reduction Gear Oil Seal - Cancelled (Cth)

AIRWORTHINESS DIRECTIVE

On the effective date specified below, and for the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive AD/DART/5.

Rolls Royce Turbine Engines - Dart Series

AD/DART/5 Reduction Gear Oil Seal 10/2009

Requirement:

CANCELLED.

This AD is cancelled on 24 September 2009.

Background:

This unique Australian AD originally raised in 1969 and again in 1987 against Rolls Royce Service Bulletin (SB) Da 72-360 Rev. 1 required a modification by introduction of an additional seal in the course pitch oil access drilling.

Compliance was:  As detailed in the requirement document, which was during next shop visit.

This AD has been sufficiently promulgated for the affected engines to have been modified by now; therefore this AD is considered to be no longer required.
