摘要：

A helicopter in a commercial flight was substantially damaged during a hard landing following a loss of engine power at Northwest region of Brazil. The pilot and passengers reported no injuries. Initial investigations pointed out absence of any damages by foreign objects. The accident was due to the failure of a blade from compressor section. Failure analysis of 4th stage disk showed that the blade failed due to fatigue which started from corrosion pits. (C) 2007 Elsevier Ltd. All rights reserved.
