## The airworthiness directive

56-02-01 AERO COMMANDER: Applies to Model 560A Aircraft, Serial Numbers 231 Through 269.

Compliance required by April 1, 1956.

Due to loss of an augmenter tube in flight, new type support clamps are required at the aft end of the augmenter tubes and at nacelle frames 148.75 and 158.75. Also, new support clips bolted through the augmenter tube at the aft end are required. Parts will be furnished by Aero Design and the rework is described in Aero Commander Service Bulletin No. 31.

This supersedes CAA telegram of December 5, 1955, which required immediate inspection and installation of a 10-32 machine screw through the bell mouth and augmenter tube.
