Cessna 550 (Citation II) Series Aeroplanes

AD/CESSNA 550/7 Anti-Skid Control Box - Modification 12/2009

Requirement:

CANCELLED.

This AD is cancelled on 19 November 2009.

Background:

This AD, raised in1984 against Cessna Citation Service Letter (SL) 550-32-5 Rev. 1, required a modification to avoid  the possibility of reduced brake pressure at temperatures above 38 degrees C.  Compliance was required before 30 June 1984.

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