AD/CJ610/6 Stage 2 Turbine Wheels 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/CJ610/6.

General Electric Turbine Engines - CJ610 Series

AD/CJ610/6 Stage 2 Turbine Wheels 8/2009

Requirement:

CANCELLED.

This AD is cancelled on 30 July 2009.

Background:

This unique Australian AD raised in1985 against General Electric Service Bulletin (SB) SB (CJ610) 72-143, or AD/GE-T/42, required removal from service of a small number of Stage 2 turbine wheels that may have had imperfect contours in the forward rabbet radius that could have limited the life of the wheel.

Compliance was forthwith.

This AD has been sufficiently promulgated for the affected turbine wheels to have been identified and removed from service by now; therefore this AD is considered to be no longer required.
