Schweizer (Grumman) G-164 (Ag-Cat) Series Aeroplanes

AD/G164/6 Carburettor Air Duct - Modification 8/2009

Requirement:

CANCELLED.

This AD is cancelled on 30 July 2009.

Background:

This unique Australian AD  raised in1966 against Grumman G164 Service Bulletin (SB) No. 37 required a modification to the carburettor air duct to preclude the possibility of excess gasoline draining into the accessory cowl and creating a fire or explosion.

Compliance was forthwith.

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.
