Lead Transportation Safety Board investigator Mike Cunningham told news media today that a preliminary review of evidence collected of the Cougar S-92 crash suggests the aircraft experienced a major problem at about 800 feet above sea level.
"There was something that happened very suddenly and abruptly after the aircraft got down to 800 feet and levelled out," Cunningham said. "After that the helicopter went into the water and it was a fairly significant rate of descent, which resulted in a pretty bad impact with the water. That's why we have the extent of damage to the wreckage that we have."
This is generally consistent with information available to date, including a log of indicated air speed and altitude for the flight.
Cunningham is quoted in other news media (link above to CBC) as saying it appears the aircraft struck the water nose first. This is based on an assessment of the damage to the recovered portions of the aircraft. The cockpit portion is reportedly heavily damaged. There is also a suggestion from some of the comments that while the main portion of the fuselage is in one piece, it is damaged considerably as well. This may have hindered the passengers from escaping.
These comments today – which are based on a preliminary examination of evidence – suggest strongly that the aircraft inverted immediately on or very quickly after impact. This would explain a number of details including the apparent absence of signals from personal electronic locator beacons worn by each of the 18 souls on the aircraft. The locators do not work underwater.
In an initial news conference (either the first or second) the search and rescue spokesperson reported that aircraft on the scene had reported beacons from the aircraft itself (it is equipped with three) and from the two bodies of two people observed in the water by the first aircraft on the scene.
Both were recovered by the first search and rescue helicopter on the scene. The Canada-Newfoundland and Labrador Offshore Petroleum Board mandates that offshore operators (oil companies) keep one helicopter within 30 minutes of St. John’s to provide search and rescue coverage. Contrary to some media reports, this meets the recommendation of the Ocean Ranger Royal commission.
The cost of the helicopter operations - including the search and rescue service provided to meet the Ocean Ranger commission recommendations - is borne entirely by the oil companies operating offshore, including the provincial government’s oil company which has an interest in White Rose and which will have an interest in Hebron, once it is built. Canadian Press reported last week that the operators have tried to shift the search and rescue cost entirely to the federal government.
Misinformation on both safety and search and rescue issues has fuelled a frenzy of media speculation and political opportunism (two links) since the crash last week.
This misinformation persists despite information from many sources, including some apparently knowledgeable comments on CBC’s website that the current issue immersion suit was developed and improved in part from testing offshore Nova Scotia and Newfoundland and Labrador.
