## The airworthiness directive

46-36-02 PIPER: (Was Mandatory Note 3 of AD-780-3.) Applies to PA-12 Aircraft Serial Numbers 12-1 to 12-207, Inclusive.

Compliance required prior to November 1, 1946.

Several instances have been reported of loosening of the cap screws attaching the air scoop to the carburetor on these aircraft, thus creating a hazard. These cap screws should be removed and drilled for safety wire. They should then be reinserted and safety wire installed.

(Piper Service Bulletin No. 90 dated July 17, 1946, covers this same subject.)
