ELSA prop change
Just when I thought I was confused enough about what defines a major alteration, and what to do if one is made, I found the following paragraph in an advisory circular.
(This subject of this advisory circular is certification of light sport repairmen. It includes the statement in bold below:)
Major Alterations. If the aircraft is issued an ELSA certificate, a non-certificated person may perform additional maintenance, preventive maintenance, or alterations on the aircraft. If a non-certificated person performs a major alteration, as defined by § 1.1
(e.g., changing the engine to another model that increases the original engine horsepower by
10 percent or more), he or she must make a maintenance record entry and a new FAA
Form 8130-6, Application for U.S. Airworthiness Certificate, and send it to the FAA Aircraft Registration Branch (AFS-750). A new FAA Form 8130-6 is required because he or she has modified the aircraft and it is no longer the same aircraft as identified on the original FAA
Form 8130-6 in the aircraft’s file. A Designated Airworthiness Representative (DAR) or FAA aviation safety inspector (ASI) will review the change(s) and issue new operating limitations for the aircraft. The issued operating limitations may require the aircraft to be put in a flight test area for a certain number of hours until the owner/operator has flight tested the new alteration and the aircraft is proven to be safe to operate within its design envelope. When the flight-testing is complete, the test pilot should sign the aircraft off as safe-to-fly in accordance with its operating limitations. (See Appendix 1, Figure 2, Sample of a Major Alteration Entry for an Experimental Light-Sport Aircraft (ELSA)).
My opinion is that if one considers the prop change to be a major repair, one should notify the FSDO and the FSDO may require some flight testing.
This circular’s statement that one has to fill out a new 8130-6 blows my mind.
Appreciate your thoughts.
