The airworthiness directive
48-19-01 BELL: Applies to All Models 47B, 47B3, and 47D Helicopters.
Compliance required by June 15, 1948.
To provide continuous oil submersion of stabilizer bar damper replenishing valves, the dampers should be rotated 30 degrees down from their present position. This is accomplished by replacing the existing damper support frames, 47-140-132-1, with redesigned frames, 47-140- 013.
(Bell Service Bulletin 64 covers this subject.)
