58-17-01 BELL: Applies to All 47J Helicopters.
Compliance required as indicated.
To preclude the possibility of failure of the 47-110-287-9 counterweight bracket assembly, the service life of this part has been established at 200 hours. All 47-110-287-9 bracket assemblies which have accumulated 200 hours or more of service must be replaced no later than August 31, 1958, and every 200 hours of service thereafter.
This replacement consists of the removal of the two 47-110-287-9 main rotor counterweight bracket assemblies and the installation of new counterweight bracket assemblies. Change and replace bracket assemblies in accordance with applicable instructions contained in the Maintenance and Overhaul Instruction Handbook.
(Bell's Service Bulletin No. 127 SB dated July 14, 1958, covers this same subject.)
