The overall number of civil aviation accidents declined significantly between 2012 and 2013, according to NTSB data published earlier this month. However, bucking this trend were Part 135 operations, for which the number of accidents doubled during the same period.
Safety of emergency medical services flights
The U.S. helicopter safety team (USHST) last week said the current accident rate of 3.94 accidents per 100,000 flight hours, measured over the first seven months of this year, represents a 51-percent decline compared with the 2001-2005 baseline determined by the International Helicopter Safety Team, the group’s parent organization. These numbers represent a 22-percent reduction compared with the 5.06 rate posted for 2009 alone and a 12-percent reduction from the 4.46 rate posted for 2012.
The number of U.S. helicopter accidents dropped 17 percent during the first six months of this year compared with the same period last year, according to data from the United States Helicopter Safety Team (USHST). From January through the end of June this year, there were 62 civil helicopter accidents compared with 75 during the same period last year. During the first six months of this year, nine helicopter accidents resulted in 15 fatalities, compared with 18 fatal accidents that resulted in 41 fatalities during last year’s first half.
The U.S. Helicopter Safety Team warned rotorcraft pilots to be extra cautious while flying next month because July typically sees more fatal accidents than any other month of the year, usually three or four accidents, representing approximately 13 percent of the annual total. The industry normally records approximately 20 fatal accidents during the rest of the year. The helicopter safety team believes the reasons for these July accidents vary, although the following three primary causes appear to stand out: collisions with wires or trees, mechanical problems and poor weather.
As part of its ongoing mission to reduce accidents, the United States Helicopter Safety Team (USHST) analyzed, by state, data from U.S. civil helicopter accidents that occurred between 2008 and 2013.
The National Transportation Safety Board on May 13 released the findings of its Special Investigation Report on the safety of agricultural aircraft operations, which can involve flying as low as 10 feet above the ground. That kind of flying presents risks from ground-based obstacles with scant room for error.
Fourteen years of accident data from the International Helicopter Safety Team (IHST) reveal that U.S. civil helicopter accidents have decreased by approximately 25 percent since the IHST was established in 2006, with an average annual drop in accidents of around 2 percent.
Metro Aviation announced Mark Breton will be joining the MRO as director of maintenance in late March or early April. He has more than 25 years in the aviation industry, with a strong background in aircraft maintenance, helicopter EMS operations and project management. Breton spent most of his career in Texas, but most recently served as the v-p and director of maintenance for Air Medical Resource Group in Salt Lake City, Utah.
Troubled by an increase in the number of helicopter accidents in the last several years, the FAA has launched the Rotorcraft Safety Initiative (RSI), an effort to curb helicopter fatal accidents.
From Oct. 1, 2012 to Sept. 30, 2013, the U.S. helicopter industry experienced 38 fatal helicopter crashes, a 100-percent increase over the same period in 2011-2012. These accidents resulted in 76 fatalities, 95 percent more than the same period the year before and the highest number of fatal accidents since 1994.
Fresh pressure is being placed on the FAA to revise and finalize its 2010 notice of proposed rulemaking (NPRM) that would mandate the installation of helicopter terrain avoidance and warning systems (HTAWS) and radar altimeters on all U.S. emergency medical service (EMS) helicopters. The NPRM drew a firestorm of criticism from affected stakeholders for favoring high-cost solutions over less expensive, and some argued, more effective safety technology such as night-vision goggles (NVGs).
