 |

I am considering re-pitching the prop on my RV9. If I do, this changes the "approved engine-prop" combination approved by the FAA when the plane was certified. Do I now have to fly off 40 hours of test time with this new engine - prop combination?

Your Operation Limitations will specify what to do. If they have the more recent wording, it will require going back into Phase 1 for 5 or so hours after a major alteration. Some very old ones required a reinspection by the Feds and they specified the test time. You have to go my the wording of your own Ops Limitations. If too onerous I suppose you could try to get them changed. I haven't heard of an Amateur Built doing that but the Exhibition types have done it.

Kim, It depends on your operating
limitations. Experimental aircraft
licensed after about 1997 had
Different wording. You will probably
Be able to place it back in phase two,
fly off 5 hours and sign it off, but
check the operating limitations to
be sure.

Holy smokes man! An RV isn't certified! Its just an alteration at most with a log book notation.

Kim,
Experimental aircraft are NOT certified. If you repitch your prop to be compliant with your airworthiness certificate, I believe all you have to do is enter the change in your log book, and do a 5 hr 'flyoff'. Check with your local EAA Tech Adviser to be sure.

I remember when I got my plane's airworthy certificate, if the engine-prop combination was one that was recognized within certain perameters I only had to fly off 20 hours. Others I know with different combinations that had to fly off 40 hours. If I were to switch to a non- "certified" engine I would have to "start over" and fly off the 40 hours as if I just started. I am just curious if changing the prop put me in the same situation.

Kim,
Call the duty officer at the FSDO and ask him if he thinks a repitch is a major mod. My guess is that he'll say yes. He might not, though, especially if you can show him evidence that others are flying with your proposed pitch. It's worth a try.
If you've got recent oplims, it probably says that, when you make a major modification, you must notify the FSDO and get their concurrence with your test flight area and fly off 5 hours - then make a logbook entry to that effect. The aircraft can then be returned to phase 2. The FSDO will want their notification in writing. Just write them a letter describing what you are doing and take two copies of it with you to your appointment with the inspector at his office. Describe your test flight area in detail. If you intend to use the same test area as your original phase 1, and why not, you should still describe it in detail in your letter. You have to call for an appointment. They won't open the door if you haven't called ahead.
If you have early oplims, you can get an update to the current set. I did it and I'm not even the original builder. They wanted me to prove that I was still in compliance with the requirements for passenger warning placard and experimental signage. I humored them with a couple of pictures. They made me jump through some hoops and shit, but they had to give them up in the end. The fun really began when they told me that I couldn't fly an experimental at my home airport (and 3 others in their area). I told them they were way off base and called in the EAA who explained to them that they were way off base and, after a week or so of dragging their feet, they caved.
Pax,

Yes, it is no more difficult getting your operational limitation changed than filling out the paper work. I had my older operating limitations modified to accommodate the 5 hour major modification change. Previously, I had to get an inspection after each major mod (which with an alternative engine involved a few), so I got with the local FDSO and had the paperwork amended – which did require one more inspection. But, since then I re-enter Phase 1, fly off the 5 hours in test mode, record any changes to basic flight parameters of the aircraft and certify in the log book that it’s safe to return to regular operation.
IF you do not have this written into your operational limitations (or have an FAA/DAR inspection) and have an accident after making a “Major Mod” you insurance company will likely deny any claim - as you have failed to comply with FAA regulations, etc.
