E&B Accident 24 Sept 2019


Recommended Posts

"At some point during the flight, the main rotors became deformed. Although indications of fatigue were present post-occurrence, the extent to which this fatigue contributed to the deformation could not be determined.

In the last moments of the flight, likely as a result of the deformed blades, the main rotor rpm decreased to a point that could not sustain autorotational flight, and the helicopter fell vertically and impacted the ground."

 

There were a lot of other things going on, probably could have overcome them... But not when carbon blade are "deformed"

Forgetting the pre-incident fatigue, it seems that the blades could be deforming during autorotation. Van Horn's test machine crashed during max gross auto testing - then this one has an engine failure (presumably due to the incorrect fuel setup), and it's found the blades deformed at some time during the flight.

Man, I cannot believe that this happened....  🤥😉

"The investigation determined that the pilot was not forthcoming with his CAMEs about conditions that were being followed by his family physician. In addition, the pilot’s family physician did not report the pilot’s conditions to TC, which contributed to TC’s incomplete understanding of the pilot’s health. If pilots do not declare all health issues to TC CAMEs and/or if pilots’ family physicians do not report medical conditions that are likely to constitute an aviation hazard, as required, TC may not be able to accurately assess the medical fitness of pilots, resulting in an increased risk that pilots will operate with diagnosed medical conditions that could affect flight safety."

I think the most notable aspect is the deceased pilot lived on Vancouver Island and had a family physician.
