## The airworthiness directive

47-41-07 BELL: (Was Mandatory Note 19 of AD-1H-2.) Applies to All Models of 47B Series, Through Serial Number 60.

Compliance required at next 25-hour inspection.

Steps should be taken to prevent the possibility of the lateral cyclic control bungee spring jumper from jamming the controls, in the event of a failure of the bungee spring, by falling down and becoming wedged against the tubular fuselage structure. Such action may be accomplished by riveting Bell P/N 47-725-034-5 to the lateral bungee jumper, with two AN 470-AD3-5 rivets spaced laterally 3/16 inch apart, in such a position that it will straddle the lower rod end of the vertical control rod emanating from bellcrank 47-725-016-1.

This alteration is covered in detail by Bell Service Bulletin 47C34 dated July 16, 1947.
