A Russian-built Kamov KA-32 helicopter made a crash landing in British Columbia Sunday, August 4. Jen Norie of VIH Aviation Group confirmed that one of their helicopters was conducting water dropping operations on a wildfire near Bella Colla, British Columbia using an external bucket when the aircraft developed an engine problem. The ship made a hard landing on uneven terrain collapsing at least one landing gear, which caused the aircraft to tip over about 30 degrees. The twin overhead counter-rotating main rotors struck the ground, which of course destroyed them.
Thankfully the two pilots walked away with no injuries, so in that sense it was a “good landing”. There were no passengers on board.
Ms. Norie said the company has been operating KA-32s since the mid-1990s, accumulating over 46,000 flight hours without a major incident, until Sunday.
A two-hectare slash fire in Powell River is now under control, and it offered a good opportunity for the Hawaii Mars to show off the important role it can play in firefighting – an essential step given that the province has announced it will not use the bomber next fire season.
Alberni Valley resources played a big part in containing the blaze. Both the Martin Mars \water bomber and Thunderbird fire unit headed out to fight the Powell River fire on Tuesday.
“It was excellent for us,” said Wayne Coulson, CEO of the Coulson group, which owns the water bomber. “We did about four loads and whacked it out with a couple of other machines, and it was a quick one.”
According to Coastal Fire Centre fire information officer Marg Drysdale, the fire was three kilometres northeast of Powell River and the resources that took care of it were three initial attack crews, two officers and half a unit crew, which were the Thunderbirds.
“And then they brought in air tankers, including the Martin Mars,” Drysdale said. “And it knocked the fire down really well.” The fire was reported at 1: 55 p.m. and the Mars bomber began its action in Powell River at 5: 05 p.m., before finishing at 6: 16 p.m. after dropping four loads.
The Transportation Safety Board (TSB) of Canada has released a report on the crash of a firefighting helicopter that occurred about 20 nautical miles northwest of Lillooet, British Columbia July 29, 2010. Two pilots were on board dropping water on the Jade fire — both of them were hospitalized with injuries. The helicopter was on contract to the B.C. Fire Service by TransWest Helicopters, based in Chilliwack.
The helicopter lost power due to a fuel flow problem. Below are some excerpts from the report:
As the helicopter slowed and started to descend past a ridgeline into the creek valley, the engine lost power. The pilot-in-command, seated in the left-hand seat, immediately turned the helicopter left to climb back over the ridgeline to get to a clearing, released the water bucket and the 130-foot long-line from the belly hook, and descended toward an open area to land. The helicopter touched down hard on uneven, sloping terrain, and pitched over the nose. When the advancing main-rotor blade contacted the ground, the airframe was in a near-vertical, nose-down attitude, which then rotated the fuselage, causing it to land on the left side. A small post-crash fire ignited. The pilot-in-command sustained a concussion and was rendered unconscious. The copilot escaped with minor injuries and dragged the pilot-in-command from the wreckage. The pilot-in-command regained consciousness a few minutes later. The helicopter was substantially damaged. The 406-megahertz emergency locator transmitter was activated, but its antenna fitting fractured; as a result, the search and rescue satellite network did not receive a signal.
Findings as to causes and contributing factors
The engine fuel control unit was contaminated with metallic debris that likely disrupted fuel flow and caused the engine to lose power.
The nature and slope of the terrain in the touchdown area caused the helicopter to roll over during the emergency landing.
