The airworthiness directive
49-34-02 BELL: Applies to All Model 47D1 Helicopters.
Compliance required as soon as possible but not later than September 2, 1949, and daily thereafter.
As a result of several fatigue failures of the attaching clamps on the ventral fin and at the attaching bolt holes of the fixed tab, these parts should be visually inspected daily until a permanent fix is available. If cracks are detected, either in the AN 735 clamps, the ventral fin, or the fixed tab, the effected part should be replaced prior to the next flight.
(Bell Service Bulletin No. 70 covers the same subject.)
