Canadaπs Transportation Safety Board (TSB) issued its final report February 9 on the fatal 2009 accident of a Cougar Helicopters Sikorsky S-92A off Newfoundland that killed 17.

The UK Ministry of Defence and Department for Transport (DfT) last week canceled the SAR-H search-and-rescue helicopter program after Soteria, the preferred bidder, acknowledged some employee misconduct. The Royal Bank of Scotland has left the Soteria consortium, which now regroups operator CHC, training and aircraft equipment specialist Thales and helicopter manufacturer Sikorsky.
Canadaπs Transportation Safety Board (TSB) yesterday issued its final report on the fatal accident of a Cougar Helicopters Sikorsky S-92A off Newfoundland that killed 17 on March 12, 2009. The helicopter crashed while attempting to ditch after its main gearbox lubrication system failed due to two cracked oil filter bowl mounting studs.
U.S. and European civil aviation authorities have issued new airworthiness directives (ADs) for the inspection and possible repair or replacement of the Sikorsky S-92A’s main gearbox. The updated ADs build on 2009 directives and mandate action on a new gearbox design that was supposed to solve the problem, at least temporarily.
Final assembly of the first production Sikorsky S-76D medium twin has begun in Coatesville, Pa., the helicopter manufacturer announced this week. Czech-based Aero Vodochody delivered the helicopter’s fuselage on November 19–a one-month delay, according to a schedule released in June. The fully assembled fuselage arrived with all electric and cockpit systems having passed acceptance tests, Sikorsky said.
Two years ago a speedboat opened fire on a Bell 412 as it departed an oil platform. A mechanic found a bullet hole in a main rotor blade after the helicopter returned to base. The passengers and crew had no idea they had been hit.
It was just another day in Nigeria.
PZL-Mielec has flown the second Sikorsky S-70i “international” helicopter. It is the first to fly in Poland, where two more units are in final assembly. The Polish company previously shipped major subassemblies for the first S-70i to the U.S., where initial flight tests were completed at Sikorsky’s West Palm Beach, Fla. facility last month.
The 117-strong fleet of Sikorsky S-92s has surpassed 250,000 flight hours. The medium twin entered service in 2004 and offshore operations have accounted for 90 percent of the air time since. The U.S. manufacturer claims mission reliability stands at 94 percent, while the fleet leader has logged 9,000 hours with Bristow. Eight offshore oil and gas transport companies fly 75 of the in-service S-92s.
Canada’s Transportation Safety Board has completed its draft report of the March 2009 fatal crash of a Cougar Helicopters Sikorsky S-92A off Newfoundland that killed 17. The final report likely will be released next year.
