Abstract

One failed aeroengine fitted on an aircraft which met with an accident was forwarded to National Aerospace Laboratories, Bangalore, for analyzing the cause of failure. Investigation revealed that connecting rod No.2 had failed by fatigue at the big end leading to breakage of the crank case. This had disrupted the lubrication supply leading to damages on all the crank pins. The primary reason for fatigue crack initiation in the connecting rod No.2 appears to be lubrication failure.
