“experienced an engine issue.”

Is it me or don’t both of those props as though they are in fine and not feathered?

Weird pictures me thinks…

Pause the video and blow it up where there is the more or less head on shot, right side does appear to be in feather, but it is difficult to be sure because of the angle. Top blade looks feathered, the other two are hard to see clearly.

No it was a Navajo.

There is video circulating on Facebook, both props are full fine and mix rich.

“experienced an engine issue.”

Too much air in the tanks, or too much jet a?

According to the report they just left the YAV airport, should not be air in the tanks, no excuse for that. Where they landed is maybe 10 minutes flying time, that would also be a long time for Jet A to show it effects, will be interesting to find out what happened here.

Good job to the crew, whatever the cause.

Video I saw was same (Prop and mixture control full forward), as well they had lots of fuel in the tanks as you could see that in same video. Props were around 1500 RPM according to the tach, and visibly turning in the video. But there's definitely one engine with what appeared to be very low MP and the other maybe around ambient?

Video is clear, but hard to decipher numbers and the L &R on those two-for-one gauges.

Is there an engine driven hyd pump on the Navajo? Maybe not feathered for gear extension with a highway where performance was under control. I also thought Jet A... it wouldn't be the first time.

But good job at end of the day.

Not if they just switched tanks at that point for example. Unlikely, but still theoretically possible if only a couple of tanks were contaminated.

word on the street is this was an engine failure along with an inability to feather and maintain altitude. If so, hero cookie to the pilot.

Heard a similar variation today with the note that on those engines the window in which you are able to feather the props after an engine failure is apparently relatively small. Not sure if that's true, but something to think about.

From TSB.....

C-GEOL, a Piper PA-31-350 operated by Red Sucker Lake Air Services, was conducting a flight from Winnipeg/St. Andrews Airport (CYAV), MB, to Red Sucker Lake Airport (CYRS), MB, with 1 pilot and 6 passengers on board. While en route, the aircraft experienced a right-engine failure (AVCO Lycoming LTIO-540-J2BD). The pilot completed the shutdown procedure; however, the right-propeller did not feather and the aircraft was unable to maintain altitude. The pilot subsequently landed safely on Manitoba Road 304. There were no injuries. There was no reported aircraft damage. RCMP responded to the site.

.....It would be interesting to know if there was a mechanical issue with the prop.....or significant delay in feathering, which can result in an inability to feather.

Possible if it wasn’t windmilling when he pulled the prop lever, the centrifugal component was not there but not really sure why the nitrogen charge didn’t work, maybe not up to the required charge. I’m sure this will get looked at. The nice thing is the other propeller is in tact, so they will be able to see if it’s a maintenance issue.

“The Lycoming Connection: The Navajo uses constant-speed, fully-feathering Hartzell propellers paired with Lycoming engines. When the propeller feathering valve in the cockpit is activated, it dumps governor oil pressure, allowing centrifugal counterweights and nitrogen-charged cylinders to drive the blades into the feather position.”
