HELICOPTER SAFETY ADVISORY CONFERENCE (HSAC) GULF OF MEXICO OFFSHORE HELICOPTER OPERATIONS AND SAFETY REVIEW
Gentlemen: April 18, 2001
Please find attached the Helicopter Safety Advisory Conference (HSAC) "2000 Gulf of Mexico Offshore Helicopter Operations and Safety Review". The membership support and response from 21 helicopter operators for this review is not only appreciated, but vital in establishing a meaningful report. Continued support is encouraged for the future.
The 2000 Gulf of Mexico oil industry helicopter accident rates per 100,000 hours was 2.04 with 9 accidents (all single engine) compared to the 16-year average of 6.9 accidents. The U.S. accident rates per 100,000 hours for all commercial helicopter operations was 3.76 and the fatal rate was 0.70, while the HSAC rates were 2.04 and 0.68 respectively. There were 3 fatal accidents with 3 fatalities (one caused by flight into water at night, one engine failure with apparent inability to maintain rotor RPM, and one remaining cause unknown).
In the last 4 years there have been 27 accidents resulting in 5 fatal accidents (18% fatal) with 6 fatalities. The leading causes of accidents have been 6 engine related (22%), 5 (18%) flight into terrain, water or obstacles, and 5 (18%) tail rotor malfunction with 5 accidents each (18%). Technical faults have accounted for 11 (40%) of these accidents. We are optimistic that by sharing this information with all operators and other oil industry group's safety initiatives may be developed to reduce accidents.
