NTSB

“The pilot departed from a private airstrip and overflew his property,” states the NTSB’s aviation investigation final report, which does not mention Bloomquist by name.

Eliott Simpson, a senior aviation accident investigator for the NTSB, said the aircraft was flying in “very poor weather conditions.”

An investigation is under way and a probable cause of the crash will be determined in the NTSB's final report in 12 to 24 months' time.

A preliminary report from the National Transportation Safety Board, or NTSB, found that two electrical blackouts disabled equipment ahead of the incident, and noted that the ship lost power twice in the 10 hours leading up to the crash.

Peter Gautier, in a July letter to the NTSB, wrote that it had been “dilgently working” on a notice of a proposed rule making with “all due haste” on safety management systems.
