As I understand the regulations the aircraft has to be maintained IAW the aircraft maintenance manual.this is the starting point and AD's are in addition to the MM requirements
Which when the MM is outdated and the TC holder doesn't want to update, it doesn't help.
I put this question the the TC holder about the AA5 MM " A UK CAA inspector has picked up on the fact that the AA5 Maintenance Manual recommends replacement of mags at 800 hrs. You and I know that it probably refers to the old Slick 4050/4051's but as recommendations in the manuals are at the present time being taken as gospel by EASA can you confirm that the recommendation does not apply to present day 4370/4371 mags."
The reply I got back was "I ran your request by our Legal Department and was told that it was not advisable to authorize any action that was contrary to the Maintenance Manual. We would need to make the change to magneto inspection and replacement at the next revision of the manual and I’m not sure when that will occur. I wish I could be of better assistance with your request but that’s the way it is with liability issues."
