The United States Army Aviation Engineering Flight Activity conducted an airworthiness evaluation of the OV-1D (Mohawk) airplane modified with a HOT BRICK III infrared countermeasure device from 11 to 22 February 1974 at Fort Rucker, Alabama, and from 17 July to 7 August 1974 at Edwards Air Force Base, California. During the test program 20 productive hours were flown. Structural and handling qualities tests were conducted, with emphasis placed on the low-speed high gross weight regime. Structural testing was limited to flutter tests of the wing store that contained the 150-gallon fuel drop tank modified with the HOT BRICK III device, the wing at the HOT BRICK III store station, and the right wing tip. Handling qualities tests included a stall investigation, determination of control margins with high asymmetric loads, single-engine minimum trim and control airspeeds, and static lateral-directional stability. Other tests included takeoff performance and an airspeed system calibration. A large discrepancy existed between the takeoff performance data presented in the operator's manual and that obtained with the test aircraft.
