Summary:

In a previous report (GAO/NSIAD-90-294, Sept. 28, 1990), GAO found that the fully-mission-capable rates for the Apache helicopter fell short of the Army's peacetime goal of 70 percent and decreased as Apache battalions accumulated flying hours. This report addresses the current status of the Army's efforts through August 1991 to improve the reliability of seven hardware components as well as to improve the Apache's maintenance capabilities. Although some progress has been made in resolving key problems, the improved components have not fully demonstrated their reliability. In addition, structural cracking in the tail boom has emerged as a potentially catastrophic problem as the aircraft accumulate flying hours, and the FM antenna reception problem has degraded the Apache's communication performance.
