AIRWORTHINESS DIRECTIVE

Cessna 310 Series Aeroplanes

AD/CESSNA 310/11 Landing Gear Torque Tubes - Inspection 5/2008

Requirement:	CANCELLED.
This AD is cancelled on 8 May 2008.
Background:	This unique Australian airworthiness directive (AD), issued in 1962, required a repeat inspection every 100 hours time in service to check for cracking of the torque tube until replaced in accordance with Cessna Service Letter 62-76 rather than a State of Design AD.  This AD was applicable to 310C, 310D and 310F models and a search of the defect reporting system of these models found that no cracking of torque tubes had been reported since 1981.  It is therefore considered that the unsafe condition no longer exists.
