Defect Trend Analysis of MI-172 Helicopters through Maintenance History

Abstract

MI-172 helicopters are a variant of MI-17/171 helicopters. These helicopters were inducted in the organization, which was originally designed and tuned to the MI-17/171 series helicopters. Since the induction was not premeditated, it resulted in diverse problems that have accumulated over a period of 3 years. This chapter focuses on the defect trend analysis and identification of root causes of the accumulated problems. Technical and flying data is collected from the user Squadron and analyzed by statistical tools. The chapter is helpful in eradicating the existing problems and suggesting pragmatic solutions for an overall improvement of the maintenance setup.
