First article preproduction flight testing was conducted in Mesa, Arizona ( elevation 1387 feet) between 6 August and 29 August 1984. Twenty test flights were conducted for a total of 32.2 hours (22.1 hours productive). Level flight performance and handling qualities tests were conducted to verify that the production aircraft characteristics are the same as those of prototype YAH-64 as tested in Airworthiness and Flight Characteristics (Part 3) tests. The level flight performance and handling qualities of the production aircraft were not significantly different from those of the prototype. Additionally, the performance data presented in the operator's manual is a good representation of the production aircraft performance. One enhancing characteristic was found (the automatic contingency power feature of the T700-GE-701 engine). Two deficiencies were identified (the false indication of engine failures which was previously reported and the poor engine/airframe response characteristics which was previously reported as a shortcoming). Four shortcomings of the prototype aircraft have been corrected in the production aircraft while 13 remain. Additionally, 13 new shortcomings were found. (Author)
