57-19-02 SIKORSKY: Applies to all Model S-58 Helicopters.
Compliance required as soon as possible but not later than October 30, 1957.
To avoid the possibility of slippage in S-58 hydromechanical clutch due to adverse tolerance conditions replace S1635-91046-1 rollers with S1635-91065 rollers.
The new rollers are three-thousandths (0.003) larger in diameter and may be identified by their dulite finish.
(Sikorsky telegraphic message SST-1-281 dated September 12, 1957, covers the same subject.)
