Cessna 500 (Citation) Series Aeroplanes

AD/CESSNA 500/10 Throttle Control Lock - Modification 10/2008

Requirement:

CANCELLED.

This AD is cancelled on 25 September 2008.

Background:

This unique Australian AD, raised in 1975 against Cessna Citation Service Bulletin (SB) No. SB 73-3, required replacement of aluminium rivet with a steel rivet in the throttle lock slide to prevent inadvertent movement of the throttle to the cut-off position.

Compliance was within 100 hours TIS after 31 January 1975.

As all affected aircraft would have been modified by now, this AD is considered to be no longer required.

Delegate of the Civil Aviation Safety Authority
