Hello POA, I am currently on the hunt for a Piper Warrior II. This will be my first airplane purchase. I am looking at one right now and have some questions about it regarding the engine compressions (I haven't seen it in person, I'm going there this weekend). TSMOH = 821 2016 compressions = 76 76 74 76 2019 compressions = 76 70 74 62 Between these two annuals the plane only flew 7 hours. (I'm assuming it went out of annual for couple years. I'm just going off some photos of log entries the seller has sent me at the moment). Since the annual in 2019, the plane has flown 13 hours. My questions are: Should I be worried? What could happen that would make compressions change this much in only 7 hours of tach time? What, if anything, can be done to improve compression? If worst case scenario would require a cylinder head replacement, what should I expect cost wise for that? Thanks for your input!
