Any ideas of the aircraft type or owner. “Twin” was mentioned

[FlySigi]

I hope it wasn't those guys. I talked to them here in Penticton last Saturday after they parked the Navajo for the night

navajo's are front and center in the advertising for the company, that does not mean at all that it has to be a navajo... but they seem to advertise having 2 of them and have no other aircraft in the promotional stuff...

Yes sources are saying it was.

[anofly]

looks like a possible survey run, then a run to calgary? flightaware....
respectfully, and condolences...
fly safe folks...

That sucks. They did surveys out of Penticton, went back to Calgary today and supposed to come back to Penticton in a few days to continue with the surveys

The last return on Flightradar24 shows 13,100 ft, vertical speed -8,500 ft/min.

My condolences to the friends and families.

And ground speed 16 knots. There were a lot of speed and altitude fluctuations over the last five or so minutes. There were also a lot of nasty storms building over the Rockies at that time.

I knew the pilot of this aircraft. He was just at the beginning of his career, and will be missed by many. RIP

Now is not the time, but a discussion on the risks of being in the back seat of a survey aircraft needs to be had.

[CpnCrunch]

Not where they were:



Only one small storm 20nm away. Certainly there was convective activity, but enough to bring down a Navajo when there was nothing at all on the weather radar?

What were the winds aloft, Cpn?

Maybe some standing wave.

I don't know what the winds were, and it's certainly a possibility that there was some kind of mountain wave. The GFA is showing some upper level troughs moving through. I was just pointing out that they didn't plough through a thunderstorm.

[Diadem]

Disregard.

What was his experience level?

My apologies, I made a mistake. My pilot friend was killed in a plane crash in BC the same day. I heard about this plane going down and shortly after heard about his death, but it was a different flight in which he was a passenger. Still a tragedy, but please disregard my reference to the pilot of this particular flight.

C-FNCI, a Piper PA-31 Navajo aircraft operated by Aries Aviation Services, was conducting an IFR flight from Penticton, BC to Calgary/Springbank, AB (CYBW) with one pilot and one survey technician on board. At 1935 MDT while descending through 14 000 feet ASL, approximately 37 nm Southwest of CYBW, the pilot indicated that there was a problem. There were no further transmissions received. The aircraft impacted terrain in the approximate area of Rae’s Glacier in Kananaskis Country. Both occupants were fatally injured.

Final report

[pelmet]

Kind of a strange accident. Any theories on why the engine lost power at that moment?

What about the oxygen system, it sounds very inconvenient and I didn't quite understand how it works.

[jakeandelwood]

I'm a little behind but how did the investigators know all the engine parameters leading up to the accident? Did it have one of those data recording engine monitors? I'll bet he wished he had another pilot in the cockpit with him to help out.

The report states the aircraft was equipped with a JPI edm, as well as the video recording system which was partly able to see the engine instruments.

The o2 system is simply a tank with a mask. Put mask on, open valve. By the way I read the report I took it to read that he wasn’t wearing the mask the entirety of the time. It does state that the mask type he was using did not have a integral mike.

[jakeandelwood]

I see, that info from the engine monitor must be gold to the investigators

[pelmet]

The bottom line is a mishandling of an engine power loss. The reason for the power loss is unknown. Hypoxia may have been at least partly responsible for the mishandling.

[Roar]

To me the Manifold Pressure trace looks a lot like an out of rig throttle quadrant, as he was reducing MP he got to a point around 24” they were both matched up nicely then as he reduced more the right starts to reduce quicker than the left, at about 18” gets them matched up again for a second then for some reason adds power to the left to 22” and reduces the right to 16” stays stabilized for 50 seconds or so then some increases in the left until cloud break, both throttles get chopped to idle (are matched up from 12” and below, power comes back up on both engines rapidly and matched to the end of recording at 16”. This seems to me to show a split throttle lever from 24”-12” on power reduction maybe that coupled with hypoxia confused him, he fixated on that problem and lost SA.
Just my initial thoughts reading that report.

[Capt. Underpants]

To me the issues with engine power are nothing more than a symptom of the hypoxia. His cognitive ability was impaired to the point he couldn’t see what was happening.
