Not a good year for Navajos. Plane is registered to Airborne Energy Solutions. Knew the guy who used to own it, but he passed on a few years back.

Anyone notice the WestJet ad on the C train in the background? Really didn’t have to go much farther but it is good to know WestJet had his back.

Engines don’t look like they were running on landing. Hope this isn’t another pilot running the aux tanks dry. We already had that idiot who landed a Navajo on a busy street.

FOOOOOOOORRRRRRREEEEE!

The golf course’s staff were the first on the scene to assist the pilot. Wingfield staff will be working to clean up the hole, but any significant damage appears to have been avoided with the plane mostly affecting a sand bunker.

Thank god!

Almost a HO IN ONE

How is it that he hit one more fairway than I did today

I’m no expert but that right one looks like it was running, left not so much.

[Gear Jerker]

Wingfield is in pretty rough shape to begin with. Maybe they just leave the plane in the bunker and introduce it as a new super hazard!

And somehow they doubled their prices without ever improving the course. I agree they should leave the plane...it'll make the course more attractive.

Right hand prop looks feathered.

[‘Bob’]

Doesn’t mean anything. The blades want to go to feather with no oil pressure and the latches can break or not latch if they aren’t on the low pitch stop.

Both look like windmilling at impact.

The following is for educational purposes and has no facts or even educated guessing asscociated:

Before facts get out I'd like someone with an investigating background to jump in to see if we, the unwashed masses who may or may'nt have flying experience, can get anything right. It looks like the RH prop was feathered yet the twisting motion that dislodged the engine from mount suggests it was running. The LH looks like it was producing little-no power but was not feathered. Is this a case of confirmation bias on my part where one has been predisposed to assume pilot error(shutting down the wrong engine) or more likely the fact one can seldom tell the truth from a few pictures?

I am not really interested in the airframes final result but more the human factors that got it there and the assumptions we make as aviators when faced with limited information and how we reach those conclusions.

Apparently Mayday declared 6 miles final; engine failure. Second engine failed at 4 miles.

Both engines failed within minutes of each other? What are the odds!??!

This unwashed human thinks wee bit too much air in the tanks.

[twinpratts]

Bad fuel, or bad fuel management, maybe

From the article.

According to the fire department, the aircraft left the Calgary airport two hours before the incident occurred.
“It took off from Calgary YYC and did appear to be potentially on its way back to YYC,” Stahl said.

Yeah, that was pure sarcasm on my part. Of course there is an extremely remote possibility would be a selector error or failure, not common on the ho but anything's possible.

Oh, I got it, but I’m unwashed.

A selector failure on both engines? If I recall correctly the selectors are separate per engine, no?

C-FZHG, a privately registered Piper PA-31 Navajo operated by Airborne Energy Solutions Inc.
was conducting a round robin instrument flight rules flight from Calgary International Airport
(CYYC), AB, to Hinton/Entrance Aerodrome (CEE4), AB, and back to CYYC with only the pilot on
board. The plan was to conduct the flight without refueling in CEE4. Prior to departure from CEE4,
the pilot determined there was sufficient fuel for the return flight to CYYC. While in cruise, with the
left engine being supplied by the left outboard tank, the pilot observed the left engine fuel pressure
start to fluctuate, and the engine operation became erratic. The pilot then selected the left engine
to run on the left inboard fuel tank. Concerned about the fuel quantity in the left-wing fuel tanks, the
pilot elected to cross feed the left engine from the right-side fuel system. During the final approach
into CYYC the right engine stopped running. The pilot secured the right engine, feathered the
propeller, declared a Mayday with ATS and elected to continue the approach. Two to three minutes
later, the left engine stopped operating, and the pilot proceeded to perform a forced approach onto
a golf course located directly south of the approach end for Runway 35R. The aircraft came to a
rest approximately 1/2 nm south of the threshold for Runway 35R. The pilot received minor injuries;
however, the aircraft was substantially damaged. There was no post-accident fire. CYYC aircraft
rescue and firefighting, the CYYC airport authority and the Calgary Police Services attended the
scene.

On site post-accident examination of the aircraft found the left-hand fuel selector in the outboard
position, the right-hand fuel selector in the off position and the cross-feed valve in the off (normal)
position. The aircraft was subsequently removed from the golf course and transported to a secure
location for further investigation. The investigation found that there was no fuel remaining in the left
inboard, left outboard and left nacelle fuel tanks. The right nacelle tank was empty, however
approximately 24 USG were recovered from the right inboard, and approximately 29 USG were
recovered from the right outboard fuel tanks.

Case closed. In case some one is wondering, thats the wrong position for the selectors if you wanted both engines to feed from the right side. Side note, the fuel in the outboard tank suggests the pilot either wasnt aware of how to manage the navajo fuel system or was careless. Generally you run the mains down enough to transfer the nacelle tanks into them, run in cruise on outboards so you always have fuel remaining in the inboards for take off and landing as the AFM recomends.

Thanks,

Any more details on fuel management would be appreciated.

I really can't tell if you're being sarcastic or not.
