AD/AA-1/4 Fuel Tank Contents Manometer Vent Lines - Modification 6/2009

Requirement:	CANCELLED.
This AD is cancelled on 4 June 2009.
Background:	This AD, issued in 1972, required inspection of each fuel tank contents manometer vent line to ensure the vent line is not kinked.  The AD compliance was before the issue of a Certificate of Airworthiness.  As all aircraft would have been inspected, the AD is no longer required.
