EC 130 crashes into house Collingwood Ontario
See attached news report, not sure the journalist is very accurate where they state “It’s believed a gust of wind pushed the aircraft into the house” perhaps this needs to be added to the thread on Jet Blast regarding journalism blunders!
Anyway see attached news report and ASN Wiki details and draw your own conclusions! https://barrie.ctvnews.ca/helicopter...home-1.6603083 https://aviation-safety.net/wikibase/346897 |
Looks like the pad is on the north side of the house (out of view to the right), open on three sides to the water. Must have been quite the gust.

Here is the summary for that case: https://aviation-safety.net/wikibase/182668 From the location description and TV footage of the EC130 accident, it is straightforward to work out the property, see below. The "V" shows likely 'pad' location and "X" being about where the helicopter came to rest (though aerial view may be out of date, with less trees now?): https://cimg9.ibsrv.net/gimg/pprune....9964cc848a.jpg |

don't forget the "propeller" going clack-clack-clack... :ouch: I hope he had the required permits from the municipality for tree cutting and residential modifications. ( In this case not exactly a “construction project.) In any case I feel sorry for him. |
CCW2 in the CFS says nothing about tree clearing on arr/dep routes!! :ok:

The DQ-IBT was actually a classic case of "dynamic rollover" just not lateral as usually occurs.
Tailwind, forward C of G (7 pax?), and part of the aircraft in contact with the ground i.e. skid toes, exceed the cyclic pitch range available for those conditions = result. |

Tailwind, forward C of G (7 pax?), and part of the aircraft in contact with the ground i.e. skid toes, exceed the cyclic pitch range available for those conditions = result. The aircraft might be in the forward part of the envelope, but from the footage prior to the set down, the aircraft is level and that tell me it was within c of g when it is able to maintain that attitude in fairly strong tailwind. 2 of the pax was kids aged 6 and 9. Landing in tailwind with your tail over a concrete structure as shown, the wind will hit the wall and push up on the horizontal stab, lifting the tail. Combined with the fairly rough set down and reflex jerk on the collective from the pilot, you run out of aft cyclic, ideas, luck and space. If there had been no palm trees or other obstacles in the way, it would not have ended like it did. |

There is extended footage of the accident including lead up on YouTube which I wasn't able to link here but Google "AS350B3 accident Fiji" to watch it. There is also an account of the accident here, including discussion of gusts: https://www.stuff.co.nz/world/south-...n-board-escape Considering the gusting, pilot set down well. Initially on front of skids. Perhaps there would have been a slight bounce when it settled on back of skids but that seems to be exactly when a gust hit given the reaction of the helicopter. Returning to the Canadian EC130 crash. TV footage suggests there may also have been a retaining wall on sea side of the landing area. So perhaps circumstances were similar. Of course it depends on strength and direction of wind and orientation of helicopter in that case. |
