AD/CESSNA 337/26 Oxygen Indicator Lights - Modification 5/2008

Requirement:	CANCELLED.
This AD is cancelled on 8 May 2008.
Background:	This unique Australian AD, issued in 1981, required the installation of a press test system in the oxygen indicator circuits so that the indicator light can be tested prior to each flight.  The regulatory requirements for checking the oxygen equipment prior to each flight are contained in CAO 20.4 and therefore separate regulatory AD action is not considered necessary.
