2010 HELICOPTER SAFETY ADVISORY CONFERENCE (HSAC) GULF OF MEXICO
OFFSHORE HELICOPTER OPERATIONS AND SAFETY REVIEW
HSAC Members: March 1, 2011
Please find attached the Helicopter Safety Advisory Conference (HSAC) "2010 Gulf of Mexico (GoM) Offshore Helicopter Operations and Safety Review". The membership support and response from 12 helicopter operators for this review is not only appreciated, but vital in establishing a meaningful report.2010 was the first year since HSAC began keeping statistics in 1984 that the GoM has recorded zero accidents. There was also a slight decline in overall flying activity to the lowest levels recorded which may have in part been attributed to the oil spill event and the reduction in deep water activity.The average number of accidents per year in the GoM since 1984 has been 11.7 per year with the last 10 years averaging 7 per year, with 0* for 2010. The 2010 GoM oil industry helicopter accident rate per 100,000 flight hours was 0.00 with a total of 0 accidents compared to a 27-year annual average accident rate of 1.66. The fatal accident rate per 100,000 flight hours during 2010 was 0.00 with no fatal accidents compared to a 27-year average of 0.52.*Note - There were three (3) ditchings in 2010 -> 2 due to loss of power and 1 due to tail rotor malfunction that were not recorded as accidents. Had these been classified as accidents by the NTSB, the accident rate would have been 0.90 per 100k hours and 0.32 per 100k flights.In the last 5 years, there have been 23 accidents of which 4 were fatal (17%), resulting in 18 fatalities and 14 injuries. The leading causes, not all inclusive, of the accidents since 1999 have been:
- 19 engine related,
- 15 loss of control or improper procedures,
- 15 helideck obstacle strikes,
- 10 controlled flight into terrain, and
- 11 other technical failures.
HSAC has published a number of Recommended Practices to address these issues and they can be reviewed at www.HSAC.org. We are optimistic that by widely and openly sharing this information with all operators and other oil industry groups that additional safety initiatives may be developed and implemented to further reduce accidents and incidents with an ultimate goal of zero events.
