AD/F27/34 Pitot Static System 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/F27/34.

Fokker F27 Series Aeroplanes

AD/F27/34 Pitot Static System - Modification 11/2009

Requirement:

CANCELLED.

This AD is cancelled on 22 October 2009.

Background:

This unique Australian AD raised in 1967 against Fokker Service Bulletin (SB) N-7 required modifications to improve drainage of the pitot-static system.

Compliance not stated.  However, manufacturer recommended compliance and Netherlands RLD required modification at first inspection equivalent to Check 5 of the F27 Inspection Guide, but no later than 1 January 1962.

This AD has been sufficiently promulgated for the affected aircraft to have been modified by now; therefore this AD is considered to be no longer required.
