Hello,
I am looking for advice on an RV-7A that I am seriously considering buying.
During due diligence I found a couple of log book entries that are concerning and would appreciate any advice from the Van's community.
Background:
- RV7A completed in 2007
- basic VFR panel
- IO-360-B1B 180 HP parallel valve (zero timed by lycoming in 1971, TOH in 1985 @ 1000 hrs SMOH, field overhaul in 2003 @1800 hrs SMOH)
- Hartzell hc-c2yr-1b (overhauled in 2003, re-sealed in 2018, prior history unknown)
Entry 1 - Mid 2018 "Metal found" : "Metal contamination found in suction screen, consulted with xxxx local engine shop and determined that metal contamination was not sufficient for removal from service" re-fly 20 hours and re-check.
I telephoned the mechanic - though he could not remember all details, said the metal was non-ferrous and small quantity and only present in the oil screen - filter was clean.
I imagine that xxx local engine shop was following guidance from Lycoming service instruction 1492D (section 8.b. "10-20" pieces)
https://www.lycoming.com/sites/default/files/Piston Pin Plug Wear Inspection.pdf
The mechanic believed, based on log book evidence, that this may have been the first time the oil screen had been checked since the field overhaul in 2003.
No further metal contamination has been found since this entry - about 200 hours flown (much of it x/c) ,several oil changes, and 2 conditionals.
Entry #2 - 1985 during top overhaul: "converted engine from io-360-b1a to io-360-b1b by removing simmonds fuel system and installing bendix fuel system" Any red flags with this?
Appreciate any insight you may have on these entries.
I am concerned about the engine safety/reliability and future resale value.
Thank you,
Reed
