49-27-02 PIPER: Applies to Model PA-12, Serial Numbers 12-1 and up, and Model PA- 14, Serial Numbers 14-1 Through 14-193.
To be accomplished not later than October 1, 1949.
Several aileron (and flap on Model PA-14) aluminum bellcrank castings (P/N 40092) have been found with cracks across the ears of the forked end. These cracks are believed caused by excessive tightening of the bolt which attaches the push rod to the casting. Inspect the forked end of these bellcrank castings and replace those found cracked.
(Piper Service Bulletin No. 109, dated November 9, 1948, covers this same subject.)
