AD 61-14-02

61-14-02 BELL: Amdt. 300 Part 507 Federal Register July 1, 1961. Applies to All Models 47J, 47J-2, 47G-3, and 47G-2A Helicopters With Float Gear Kit No. 47-706-661 installed.

Compliance required as indicated.

Several cases of failures have been reported of the forward cross tube failing near the left attaching point (cross tube to centerframe) through drilled holes which have been welded closed and filed smooth.

To remove defective tubes and preclude the possibility of float cross tube No. 47-512-111-9 failing during landing, the following one-time inspection is required:

(a) Within the next 10 hours' time in service after the effective date, remove paint from around the P/N 47-512-111-9 cross tube for an area approximately 2 inches on each side of the stop plates, P/N 47-500-024-1 and visually inspect for any indication of welded holes in this area.

(b) If no evidence of welds is found, prime and repaint as necessary.

(c) If any indication of a weldexists, replace the cross tube with an FAA approved part within the next 5 hours' time in service following the above inspection.

(Bell Service Bulletin No. 132 dated May 23, 1961 covers this subject.)

This directive effective July 12, 1961.
