摘要: Abstract A helicopter in a commercial flight was substantially damaged during hard landing following loss of engine power at Northwest region Brazil. The pilot and passengers reported no injuries. Initial investigations pointed out absence any damages by foreign objects. accident due to the failure blade from compressor section. Failure analysis 4th stage disk showed that failed fatigue which started corrosion pits.
