47-32-13 BELL: (Was Mandatory Note 13 of AD-1H-1.) Applies to Models 47B and 47B3 Helicopters.
Compliance required at the next 100-hour teardown inspection.
Additional strength in the antitorque rotor control system has been found desirable as a result of service experience. This may be accomplished by replacing the aluminum alloy rivets in the tail rotor pitch adjustment rod assembly with steel rivets.
(Bell Service Bulletin 47C44 dated June 16, 1947, also covers this same subject.)
