This engine > has 1.6 hours on it since rebuild (which admittedly was 10 years ago). I take it that you bought the engine 10 years ago and are now just finishing your project? (Finally saw DAR comment at end) Why are you doing a conditional inspection now? I'm missing something here so my comments may not be accurate. If just using it as a checklist instead of a true conditional inspection ..... just look at the items. > The rebuilder checked the compression. Seems to run good. Do I > really need to check the compression? Most definitely yes. All kinds of things happen to degrade an engine and compression test .... especially after 10 years sitting and just after a major rebuild. The test isn't difficult and other than oil pressure is the only real indicator of the engines health. Sitting this long .... especially if the engine wasn't pickled ..... I'd be worried about rust on the cam and the cam followers .... this will destroy both if not cleaned up .... which means tearing the engine down. If it's in a really dry climate you might have dodged this bullet. My advice is to pull a cylinder just to make sure. Time invested here may save you big bucks in the near future and the parts are cheap. > Engine mount bolt torque.

It's called a manometer. Simple to make and use. Your EAA chapter might just have one ..... and the expertise to use it. > Isn't that what the first flight or high speed taxi is supposed to > check?

There is no benefit from a high speed taxi test (IMHO) and just invites the opportunity for Murphy to stick his nose in it.

Is there a FAR that > says a GPS cannot be used during a BFR or IPC? I don't know that answer. My examiner didn't care about my AWM. But just to make your guy comfortable, take out the AWM and use a chart and a compass. You might get a copy of the handbook that tells the examiner what you're required to demonstrate as part of the BFR. There's probably one for IPC, but I don't know for sure. That book (BFR) says one hour of ground and one hour of flight ..... and my guy won't accept any less time, even though he's my passenger a lot. He goes by the book!

Every one I know wouldnt do an anual without it. I installed a 170 hr engine three yrs ago, replacing my 2280 hr 320, it ran ok, but #3 only tested 60 over 80. They were Superiors, and I had that cyl OH. The other 3 were in mid 70's. Charlie H ________________________________ Message 8 _____________________________________ Time: 06:04:10 AM PST US From: Kelly McMullen Subject: Re: RV-List: Handheld GPS during BFR/ IPC Guidance for both flight review and IPC are contained in the practical test standards booklet (PTS). You have to be prepared to demonstrate satisfactorily anything in the PTS for your highest rating. Most CFIs are going to look that you operate within safe parameters and that you never give them doubt about safe completion of the flight. Our EAA chapter has started offering a 3-4 hour ground school for BFR, that most local instructors accept in lieu of their personal time. Lengthy, yes. How many have kept up with all the reg changes since you got your certificate? How many attend any safety seminars? On-line courses with AOPA or FAA?
