I hear what you say but the last annual/ARC renewal was over £3k for me. Compare that with Rod1's celebrated £300 Permit renewal..... My ex-CAMO did not allow me to 'assist' in the Annual so no scope for savings there
Similarly, the prop that came to replace the broken one was the 'certified' one, £461 more than the identical 'uncertified' one to include the notorious Form 1.
I questioned that, but was told that the uncertified one was only for Permit aircraft - nothing about a privately-operated exemption
