AD/LTS/3 Power Turbine Governor Functional Check/Replacement 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/LTS/3.

AlliedSignal (Lycoming) Turbine Engines - LTS 101 Series

AD/LTS/3 Power Turbine Governor - Functional Check/Replacement 9/2009

Requirement:

CANCELLED.

This AD is cancelled on 27 August 2009.

Background:

This unique Australian AD originally raised in 1985 and again in 1986 against Lycoming Service Bulletin (SB) No. LTS 101C-73-20-0058 Rev. 1 paragraphs 2, 3 and 4, or AD/LYC-T/25, required an evaluation of some power turbine governors to verify performance.

Compliance was:  Within 100 hours TIS after 31 May 1985 or on installation of affected engine/power turbine governor, or prior to issue of Australian certificate of airworthiness.

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