CL-415 encounters problem on Newfoundland lake

(Originally published at 1:12 pm MDT, July 4, 2013)

Reports are preliminary and a little vague at this point, but a CL-415 air tanker had a problem during or shortly after it was scooping water on a lake in western Newfoundland Wednesday. Both pilots are OK but were being checked out in a hospital as a precaution. The Newfoundland and Labrador’s Department of Transportation and Works confirmed that they were notified about the incident at about 3:30 p.m. that the aircraft had a problem while scooping water at Moosehead Lake near the town of Wabush.

The CBC reported that the Bombardier CL-415 lost power shortly after picking up the water and the pilot and co-pilot managed to turn the aircraft around and land safely on the lake. They got out and stood on the wing until they were rescued.

CTV News quotes Bruce Mullen of the Transportation Safety Board’s Atlantic region office as saying, “When the aircraft was riding along the surface of the water, picking up water, it appears that something went amiss and the aircraft had an incident and impacted the water.” He didn’t know the extent of the damage to the plane but it was still floating on the surface of the lake, he said.

A spokesman for the Department of Transportation and Works said it was working on a plan to retrieve the Bombardier 415 water bomber from Moosehead Lake. He said it is not known how long that process might take.

Report released on 2010 crash of helicopter in B.C.

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

  1. The engine fuel control unit was contaminated with metallic debris that likely disrupted fuel flow and caused the engine to lose power.
  2. The nature and slope of the terrain in the touchdown area caused the helicopter to roll over during the emergency landing.
