Seems to me this type of occurrence does throw a damper on the idea of "a cheap to buy jet and fly it until" something like this happens. Is this event the end of that plane and if so did the investment pencil out?

Is this event the end of that plane and if so did the investment pencil out? :shrug: All planes are risks, financial and otherwise. This is true be it a J-3 Cub or a 747. A 501SP could be a $300K airplane, so not much risked. If the engine failure was contained, limited to the engine nacelle, then buying a used engine and some repair work and this plane is back in the air, say for $200K maybe. If the plane is totaled, then sell the engine on the other side and part it out. You get something. I would be curious whether the insurance comes into play. Is this an "accident"? Mike C.

Insurance is going to pay to replace the cowling which is about $10K with my parts. The engine was worth about $45K. Labor is about $10K.
Not a financial catastrophe.

Agreed but 5 reported cases in the millions of 500/501 hours is a pretty low probability. All reported cases occurred during take-off spool up.
Any idea how many cycles on that engine? Greater than 5000?

The engine is a goner, no doubt. Time to buy a used engine. Mike C. How does that blade exit area line up with the pressure vessel of the 501? Kevin

Or to be more specific, the engine rotor zone is behind the pressure bulkhead. But there is cabin pressure plumbing back there, like an air cycle machine and the bleed air ducting, so you can get a depressurization event when an engine grenades and cuts through things in that region.

Mike If I'm understanding, the owner is making a claim for only $10K. Is it worth it; won't his go up a TON for making a claim? The old engine was worth $45K...can the replacement engine be had for that?

When I sold the airplane (so maybe add 300 hrs/cycles to these) :
Airframe 8796.9 Landings 7888
TT Eng 1 8597.9 Cycles 7726
TT Eng 2 8574.9 Cycles 7713
The left impeller had 5737 cycles on it with 668 remaining until getting thrown away.
The impeller AD inspection was accomplished at 6965 cycles

I highly doubt the owner is making a claim. I'm just speculating what insurance would pay for. Replace "is" with "would" in my original statement.
