I was flying into La Guardia on Air Canada and I saw a Bonanza rolling out
with the engine stopped. By total coincidence, exiting the plane, I got a
call from that pilot's instructor who'd briefed the pilot on this X/C. He
said that there was a known problem with that plane and, I think, said that
it was not an uncommon problem with that type of plane. Odd thing,
coincidence.

My fuel-injected, turbo-normalized Bonanza had a newly rebuilt engine
installed last February. Upon completion of the work, I took the aircraft
up for the proper first flight break-in. When I landed, the engine quit
just as I touched down (low idle) on the runway.

I was able to restart and taxied back to talk to the mechanic. He adjusted
the low-idle mixture so I took the aircraft up for the second flight
break-in. Again, upon landing the engine quit.

Suspecting something else now, the mechanic ran the aircraft on the ground
and was able to duplicate the problem. He then suspected the fuel pump so
he took it off and sent it back to the company who supplied it to the
engine rebuilder for inspection. The fuel pump inspectors discovered metal
shavings inside the fuel pump that were cutting off fuel flow at low idle.
That opened up an entire finger pointing session. Nice...

The source of the shavings was never identified but it was concluded that
somehow they were introduced when the engine was on the test cell.
