I have recently had to try and track down a MMEL for a C172.
Ended up talking to a nice chap at the CAA who said that they don't produce MMEL's for under 5700kg.
After talking to one of the inspector of paperwork blokes he told me to copy the FAR for SEP and hack out the bits that we don't have.
IO540-C4D5D i am welll aware of students who write everything down. And I don't bollock them for it.
There are things going on tech all the time.
Fuel pumps
Vac pumps
Mags
Alternators
If the Authorities got hold of a log book where none of these items went tech ever they would be a bit suprised.
But schools being schools will want to postpone them getting fixed until the next check.
I have as proberly most instructors have run with a knackard vac pump but the plane is only used dual or by an experenced pilot who knows the score in VFR.
But there are some things which should go in, all of which effect flight safety.
Compass
Dead mag
tyre creep
alt.
leaking fuel tank
Etc if you don't log these type of items and an accident occurs and you were the last to fly it, your in for a day in court as well.
The view i was putting across was if you have complained repeatedly about about an important instrument and there not doing anything about it log it.
