AIRWORTHINESS DIRECTIVE

On the effective date specified below, and for the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive AD/SWSA226/5.

Fairchild (Swearingen) SA226 and SA227 Series Aeroplanes

AD/SWSA226/5 Wing Centre Section Improved
Venting - Modification 6/2009

Requirement:

CANCELLED.

This AD is cancelled on 4 June 2009.

Background:

This AD, raised in 1972 against Swearingen Service Bulletin (SB) SB 57-30-3021, required installation of vents and vent holes to improve the wing centre section venting.  Compliance was required within 100 hours TIS or 3 months, whichever occurred first, after 31 July 1972.

As all affected aircraft would have been modified long ago, this AD is no longer required.
