## The airworthiness directive

62-11-01 GENERAL ELECTRIC: Amdt. 434 Part 507 Federal Register May 3, 1962. Applies to All CJ805-3, -3A, and -3B Engines Equipped With GE P/N 105R684P5 or 105R684P6 Thrust Reverser Actuating Pumps.

Compliance required at next engine overhaul.

Instances of thrust reverser pump failure have occurred causing the reverser to be inoperative and resulting in asymmetric power conditions upon application of reverse thrust during the aircraft landing roll. To correct this unsafe condition replace reverser pumps GE P/N's 105R684P5 and 105R684P6 with GE P/N 105R684P10 reverser pump, or modify the reverser pumps to conform to the P/N 105R684P10 by reducing the width of the pump drive gears and enlarging the size of the pump shaft oil seal vent in accordance with GE Service Bulletins Nos. (3B)78-1 and (3)78-16. Pumps so modified shall be reidentified as P/N 105R684P10.

This directive effective June 4, 1962.
