Abstract:
Part 5 of the AH-1G helicopter Phase B test was conducted at Yuma Proving Ground, Yuma, Arizona, from 6 through 9 February 1968 by the US Army Aviation Test Activity, Edwards Air Force Base, California. The test consisted of firing the XM-28 chin turret, with one 7.62 millimeter automatic gun M-134 and one 40 millimeter grenade launcher XM-129 to determine the weapons systems effect on the stability and control characteristics of the helicopter. No safety of flight restrictions resulted from firing this system within the flight envelope. Correction of four deficiencies is mandatory to provide acceptable mission effectiveness and safety. These deficiencies are the inadequate forward visibility from the pilots cockpit due to the N-9A gunsight installation, the lack of a fire warning system, the lack of a standby generator for IFR flight, and link jam malfunctions of the minigun during symmetrical pull-out maneuvers. Fifteen shortcomings, for which correction is desirable, limit mission effectiveness. The reliability of the weapons system was questionable and service type testing should be conducted prior to system acceptance. Correction of the deficiencies is mandatory and should be tested prior to deployment. Shortcomings, for which correction is desirable, should be corrected on a high priority basis.
