EN48,
Whilst I think it is good to have such info passed on, I think that Student pilots will still be able to fly solo, its just that the test must be carried out by a fully qualified Pilot, who in the most cases I could think of would be the Flight Training Establishments Fi or Cfi who would be a qualified and experienced pilot.
One thing also should be kept in mind and that is the preservatiion of ones own safety, many people who want to fly know a little about what could mechanically go wrong, but equally there are many who would not know how to conduct the " Knock or Tap test" to hear the subtle change of tone that could indicate any form of delam.
For I think the FAA have taken a bold step in putting out this AD, the thing is how will the RHC react to it will they be brave and make it world wide or will they as they seem to now and as in the past keep quiet and say Nowt,... except to blame the Pilot!!
