47-32-05 BELL: (Was Mandatory Note 5 of AD-1H-1.) Applies to Model 47B.

Compliance required before next flight.

Remove the main rotor mast spinner assembly from all Model 47B helicopters, in order that the possibility of its jamming the mast control tubes, in the event it becomes loose during flight, is eliminated.
