Learned something interesting today about Williams. A friend was looking at marrying a lousy airframe Sierra Stallion (with good motors) with a lousy motor Stallion with a good airframe. However, after contacting Williams, the program does not transfer with the motors so all that equity is lost.

Williams is the worst.

I picked up my Mustang today after getting my engine reinstalled. Pratt delivered it to my maintenance facility November 23, but I wasn’t able to get there until November 29 due to holiday travel. The reinstall went smoothly, and everything is working well. The rental engine is on its way back to Pratt.

The cause of failure was the #3 bearing. The bearing cage was fractured in multiple pieces and had seized the compressor section, which explains what I encountered inflight. All associated parts were carefully examined and replaced. No stone left unturned. They also completed all items of the hot section inspection, since it was within 200 hours of the HSI.

Pratt was very thorough and methodical. I have no complaints. I also appreciated the use of a complimentary rental engine throughout this process. I put 68 hours on it. Glad to have everything completed.

Question!

When you rent an engine is the rental rate by the hour or by the calendar number of days you have the engine?

You put 68 hours on the rental engine in how many days? Seems like you are flying a bit <grin>.

answer:

You pay your usual hourly program rate for the “rental” engine. So it costs you nothing additional.

Engine failure in a jet at altitude should be a non-event.......Get a cup of coffee and count to 10. The only emergency would be self induced .. IMO

Tim, you couldn’t be more correct. The engine failure at altitude was a non-event. Simply a schedule disruption.

Tom, Pratt has a schedule for the rental engine, which has a per hour charge with a monthly minimum. I had the rental engine four months. However, I don’t recall the rates, since I wasn’t paying for it. Allen is correct in that you continue to pay your program charges, even though you’re using their engine.

I think I may need to delete the scheduled rental engine
Glad the entire process worked as it should.

Tom, I’m responsible for it until it gets back to Pratt. Should be another day or two. I’ll let you know.
