Also, note in the last log entry (from 2015) that they replaced the hobbs meter, which may explain why it seems like it hasn't flown.
Yes, that tripped me up, the first go 'round. Then I back checked the hobbs and I think the 850 hour engine is actually more like 1050 hrs.
Still, a lot of new "Software" (hoses, uppolstery, switches), lots of instrument OH's I found one reference to removing/replacing a skin panel for corrosion. Also, some sort of fuselage structural repair to an area similar to Glenns 680FP (Sta: 125 to 140). This one has had a few spar inspections.
My feeling is that the engine Overhauls were done locally, possibly on the field in Las Vegas. I didnt' sift through the OH parts list; but that should be done. Also look closer at WHO physically did the OH.
"I" can OH an engine, but its been nearly 30 years and I'd have to do a couple of my own for practice, before Id commit to flying behind one. I'd insist that a real engine builder look over my torques/specs the whole time. Its not magic, but it is tedious work following the specifications.
