Why do I need to overhaul or renew all my ancillaries at engine overhaul time?
I had magnetos overhauled 40 hours before my engine overhaul, yet I had to do them again, at a cost of about £1000. I put a replacement starter motor on last year but I had to have a replacement or overhaul. I've just bought a new alternator where there was nothing wrong with the old one, and they are easy to change on my particular aircraft.
Why do some maintenance organisations insist that it's CAA/EASA rules that seatbelts on Cessnas must be replaced every 10 years? A friend of mine had his seatbelts replaced under this rule, than 10 years later had to have them done again...all of them...despite having never carried anyone in the back of his aeroplane. He had to throw out and replace the brand new unused seatbelts.
Why the insistence of having magnetos overhauled every four years, or vacuum pumps and so on?
Why do these and other things have calendar lives independent of how many hours they have been used for?
