I appreciate that comment. I should have indicated that any aircraft that received an individual sign-off from the FSDO may be compliant. I would insure that any such sign-off still holds, as the FAA has recently refused to accept some "local" approvals (witness Alaskan Mods, etc.) and severly restricted the local FSDO's from new approvals. I do hope that someone can find documentation that permits retention of the aerobatic certification. I probably would not convert mine (an A150M, I wanted the 6" larger rudder), but if ever I sold it, I would be able to state that it was convertible to the 150 engine. Perhaps a member can find the permitting language in their documentation.
