AD/DHC-6/1 Upper Rudder Fairing Modification Cancelled (Cth)

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/DHC-6/1.

DHC-6 (Twin Otter) Series Aeroplanes

AD/DHC-6/1 Upper Rudder Fairing - Modification 12/2008

Requirement:

CANCELLED.

This AD is cancelled on 20 November 2008.

Background:

This AD was raised in 1967 against De Havilland Canada Modification Bulletin MB 6/1013, requiring removal of the upper rudder fairing to preclude the possibility of the rudder control lever becoming fouled due to a damaged or distorted upper rudder fairing.  Compliance was required before 1 September 1971.

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