Perry,
I picked up on the same item, at the end of the report.
One doesn't get galling of the rotor bearing surfaces from lack of apex seal lubrication. Plus, the oil pump itself exhibited galling. Sounds like he lost his oil pressure.
If he'd only be flying 1.25 min., that pretty much limits it down to a leak somewhere in the path to~from the oil cooler.
If y'all have any doubts about the security of your oil path, now's a good time to make certain that nothing can easily come loose.

If Ken Welter is still on this list, he can fill you in. Basically the pilot was warned by Ken in advance of his first flight, that if his engine quit, he would enter an un-recoverable stall because his cg was incorrect. The high thrust line of the Coot was a factor. I don't know the details that caused his engine to quit running, but it was not due to the missing metering pump, as the NTSB report suggests.
