Thanks for the reassurance that any reputable maintenance organisation will be able to deal with the Mooney...although if there are any that currently maintain several planes I would like to know....Cambridge sounds like one...
Well of course, that is if you can find any......reputable ones that is.
If you get a Mooney, or any other complex type, ensure it is maintained under the Manufacturers Maintenance Schedule, found in the Manufacturers Maintenance Handbook.
It will save you endless grief, thousands of pounds/euros, and should save you falling out with your chosen Maintenance co.
A lot of them have not one clue about properly maintaining some of these types.
From the tired voice of experience.
Good luck
