Identification and Analysis of Army Helicopter Reliability and Maintainability Problems and Deficiencies. Volume I. Introduction, Analysis, and Summary

The report presents the results of a study and analysis of reliability and maintainability problems encountered by the Army's current generation of utility, attack, training, observation, and cargo helicopters. Problem identification is based on an extensive series of interviews with personnel who have had long experience in operating, supporting, and maintaining these helicopters in Vietnam, in CONUS training bases, and in other missions and deployments. Problem validation, expansion, and quantification are based on a large volume of publications and statistical data describing various aspects of reliability and maintainability problems identified. A STANDARD FORMAT PROVIDES A DESCRIPTION OF EACH PROBLEM, ITS CAUSE, ITS DURATION, AND ITS IMPACT ON SAFETY, MAINTENANCE WORKLOAD, AND AIRCRAFT AVAILABILITY. Mission and deployment effects on each maintainability and reliability problem are specified, and remedial actions taken or in process to correct the problems are described. Problems are grouped by helicopter type and within each type by functional group. See also Volume 2, AD901457.
