Federal Aviation Administration Data Parameters • The following data includes only “workingtype” (turbine-powered) helicopters regardless of what rule the helicopter was operating under at the time of the accident. – NO reports of “training-type” helicopters (reports involving R-22, R-44, etc.) are included. • The data sources included NTSB accident reports and NPTRS record reviews for all accidents, incidents and occurrences. – NOTE: no VDRP reports were reviewed. Federal Aviation Administration Trend Identified • • • • • 2007 – 8 of 103 accidents = 7.7% 2008 – 10 of 83 accidents = 12% 2009 – 6 of 78 accidents = 7.6% 2010 – 13 of 68 accidents = 19.1% 2011 – 7 of 108 accidents = 6.4% Federal Aviation Administration Summarized Data • 2007 – 2011: 440 reported rotorcraft accidents and incidents occurred in the US. – Of the 440 reports, 10% (44 total) were caused by maintenance errors. • These accidents resulted in 13 fatalities, 10 serious injuries and 21 minor injuries. Federal Aviation Administration Maintenance Actions • The maintenance action that preceded most of these accidents was engine changes. – Over 25% (12 accidents) occurred following engine changes Federal Aviation Administration Specific Maintenance Errors • 9 instances of failure to properly torque lines/fittings. – Causing 12 fatalities, 6 serious injuries and 7 minor injuries • 12 instances of failure to properly safety component hardware – Causing 9 minor injuries • 12 instances of failure to accomplish a proper inspection Federal Aviation Administration Failure to properly secure/inspect Federal Aviation Administration December 7, 2011 Inadequate maintenance of the helicopter, including (1) the improper reuse of a degraded self-locking nut, (2) the improper or lack of installation of a split pin, and (3) inadequate post maintenance inspections Contributing to the improper or lack of installation of the split pin was the mechanic’s fatigue and the lack of clearly delineated maintenance task steps to follow. Contributing to the inadequate pos tmaintenance inspection was the inspector’s fatigue and the lack of clearly delineated inspection steps to follow. Federal Aviation Administration 26 Failure to Properly Torque Federal Aviation Administration July 28, 2010 • The helicopter experienced a complete loss of power and crashed. The accident flight was the first full flight following an abbreviated post maintenance check flight after significant engine work. It was determined the contract mechanic did not properly install the fuel inlet union during reassembly of the engine. Federal Aviation Administration Failure to properly torque Federal Aviation Administration November 1, 2009 • The pilot lost power and autorotated into the water. 36.7 hours prior to the accident, the turbine module had been replaced. The cause was determined to be maintenance personnel’s failure to correctly torque the Pc line following that engine maintenance. Federal Aviation Administration Failure to inspect and Torque, Reuse of worn components Federal Aviation Administration March 8, 2007 • The cause of the accident was maintenance personnel failed to properly torque the flight control servo lower attachment clevis and reinstall a functioning lock washer. This resulted in a flight control disconnect and complete loss of control of the helicopter. Federal Aviation Administration Failure to Properly Inspect Federal Aviation Administration July 28, 2010 • Just prior to liftoff, the helicopter began to shake violently and came apart. Examination of the wreckage found a 2 ft. outboard section of the MRB had separated. The cause was determined to be inadequate maintenance inspections of the MRB inertia screw holes which resulted in failure due to fatigue. Federal Aviation Administration The Current State of Affairs • Current regulations that pertained to most of these accidents did not require RII inspections following maintenance to critical components. • SHOULD THEY?? Federal Aviation Administration What can we do? • Awareness is not only crucial for the maintenance crews but also for the flight crews. • Communicate: you are the front line of defense • FAA Dr. Bob Johnson mx human factors www.faa.gov/.../AMT_Handbook_Addendum_Human_Factor s.pdf • The Agency currently has a national goal to reduce the number of GA accidents… WHAT CAN WE DO NOW??
