Condition Inspection Logbook entries?

Steve,
It depends on when your operating limitations were issued. You are locked in to those. The current op limits allow you to change engine (as long as you don't change to or from reciprocating to turbo-prop) with a simple logbook entry. You must notify the local FSDO to get concurrence for your flight test area. Your operating limitations should give you details on what is necessary.

Mel,
I guess I am not sure what you mean by "operating limitations". Are you referring to Phase I, Phase II limitations? I guess what I am getting at is, do you have to go through Phase I flyoff again with the new engine? It sounds like your post is telling me there is a new Phase I period of flyoff for the new engine that the FSDO will require. Is this the case?

I am inquiring on this as I replaced an old engine with a new engine (same make, model, type, HP, etc. as the old engine) in my current experimental airplane I am flying now. So, if the engine is an identical replacement with a new from the factory engine is there a new Phase I flyoff I will have to perform?

If you replaced with identical engine; ie same model, same hp, etc. then you just need a logbook entry. If anything else changes, you must follow your op limits. When were your operating limitations issued? Your operating limitations must be in the aircraft at all times. Look at your 8130-7 (airworthiness certificate). It states that "Operating Limitations Dated xx/xx/xxxx are a part of this certificate". Airworthiness Certificate is not valid without the operating limitations.

The Airworthiness Certificate was issued in Sept '04. I will examine it this evening when I get out to the airport. I did replace the engine with an identical one. It is really a long block replacement as I kept the carbs, exhaust, starter, etc. and just replaced the engine itself. I have made the log book entry already but did not know if I needed to notify the FAA or flyoff any Phase I time again. Thanks for the information.

Let's say, in a few years, you were to sell me your engine. I would want the engine logbook(s) but not your AC logs. So it seems common sensical to record in both/separate logbooks. I'm clueless on the legalities, but then again common sense and "justice" don't always live in harmony.
