Quite agree, Bertie - provided there is proper supervision. In Canada, the pilot does the 30 hour inspections on AS 350s and the 25s on 206s, including greasing the heads, etc, aside from being authorised to remove batteries, change bulbs, etc.
Can't see why it can't be done in UK myself, especially as the CAA seem to want the lesser qualified engineer to do the work on the aircraft anyway, with the more qualified one supervising. Myself, I would rather it be the other way round!
