47-32-04 BELL: (Was Mandatory Note 4 of AD-1H-1.) Applies Only to Model 47B Serial Numbers 2 Through 6, 10 Through 17, and 20 Through 22.
Compliance required not later than next 25-hour inspection after September 15, 1947.
Placard the antitorque rotor blades, "Do Not Use for Handling Helicopter," to warn ground personnel against using the antitorque rotor blades as handholds when hand-maneuvering the rotorcraft on the ground. Mishandling of these blades may cause unseen damage to them, which, in turn, may result in failure of the blades in flight. The stainless steel leading edge should be inspected carefully, particularly near the root, for cracking.
(Bell Service Bulletin 47C16 dated March 25, 1947, covers this same subject.)
