47-32-08 BELL: (Was Mandatory Note 8 of AD-1H-1.) Applies to Models 47B and 47B3 Serial Numbers 2 Through 5, 7 Through 11, 13 Through 17, 19 Through 25, 27 Through 78.
Compliance required not later than 25 hours operation after September 15, 1947.
The stabilizer bar dampers should be inspected for the presence of an "AL" stamped on one of the attachment lugs. If such a marking does not appear, thoroughly inspect visually for leakage or other defects and replace if necessary with P/N A12141 (Houds) (stamped "AL"). A cracking or failing of the phenolic abutments has been reported, wherein the subject dampers have been rendered ineffective, thus affecting the flight characteristics of the helicopter.
(Bell Service Bulletin 47C47 covers this same subject.)
