It might require a prop inspection, but I’d like to see the data behind that requirement. If you think about it, there are many asymmetric loads within a reciprocating engine. Think about the asymmetric loads on a piston pin given the piston is reversing direction every 180°. It’s pretty amazing to consider how much pressure it takes to disrupt the hydrodynamic plane. I think the motor mounts are toast. I’d be curious to see how the firewall fared. this is a long video, but it’s very well done and conveys a lot of information that most of us don’t think about in terms of the physics of multi cylinder, reciprocating engines.

That’s weird. I’m pretty sure mine is all metal. Same components but not plastic. The of flapper in my passenger butterfly valve is half missing but other than that the system has been very durable, especially given the high temps it endures. At the max heat setting, my system puts out near 200° at the center vent.. cannot imagine plastic withstanding those kind of output temps for any period of time but apparently it does.

Very sorry to learn of Andrew’s passing. I enjoyed his wit and sensor humor as well as the images he shared of many beautiful flying destinations. He will be missed. RIP.

You’re kind of making my point. It’s likely not the power, it’s the heat.

Is it that they’re always going to be hot at 90%? I would have little concern running my NA cylinders at 90% for extended periods.

I think it’s a longshot as well, but should be ruled out.. I think the easiest way to check is to just put a bit of rotational force on one of the stop brackets and see if it moves. Seems unlikely that break-in oil would have an effect on the governor. I’ve run all different types of weight oil in mine without a problem. Is the problem duplicatable on the ground?

Don’t judge my safety wire too harshly. It’s super tight in there.

I’m wondering if the governor is rotating in the housing. The PCU 1000 like most governors can be “clocked” within the housing to accommodate a multitude of prop cable mounting positions. It’s conceivable that if the governor was not properly tightened down or has become loose, it is moving slightly..

The trends I’m quoting are per 100,000hrs. You can quibble with the methodology but it’s the best we have.

Pilots have really not broken much new ground in terms of how they bend airplanes. GA accident rates are generally trending down.

Well, I might agree with you if I thought that the retractable gear and prop had anything to do with this mishap. I’ve landed my plan on ice many times it’s just that there’s always been asphalt underneath.

Looks to me like he was trying to make a short field landing and ran out of energy just before the threshold.

Thanks for the feedback folks. And just to be clear, I have not nor have I ever set any plane afire. My question was driven by a trend I’ve seen recently of winter time engine fires from over priming and poor fuel atomization. Be careful out there.

They have a fairly extensive collection of used parts. I’ve purchased parts by mail from them. They recently relocated. I’ve never had work done there but I’ve never heard anything negative.

Look forward to speaking next week. Just so we’re clear on working “perfectly”.
