>We'll all be interested to hear what they find.      

 

Went to see David Atkins yesterday. He continues to be a good person and business to deal with. He took the time amidst the chaos to have the engine completely torn down and inspected piece by piece as it was disassembled – while I was there. It all looked pretty good until the front housing E-shaft bearing. There was definitely some abnormal wear there and some scuff marks on the E-shaft. There was also some wear on the center bearing but just on the forward 1/10th of an inch. He’s going to replace the bearing and rebuild the engine and then check the oil pressure.

 

He suggested I look for any source of chips or anything coming from the PSRU. Something caused that front bearing to get worn way too quickly and he suspects there may be a problem with the PSRU since we didn’t find anything in the engine that looked like it was shedding metal.

 

I’ll try to get up to the hangar in the next couple of days to retrieve the RD-1B and bring it home for disassembly and inspection.

 

ThanxAll,

Joe Hull
