No idea!!
If you want to make a difference you can make a point of sharing some of your knowledge with the relaively inexperinced pilots you come in contact with.
If ther e is a decowled aircraft in the hangar invite them over and point out some of the "good" bits, trace the magneto leads and discover which mag fires which plugs, look at the vac pump and explain how they usually fail, identify the leads coming off the alternator.......I could go on and on
The responsibility for improving the working knowledge of new pilots lies with US! Sure instructors/flying schools may be letting the side down but then again in this dollar driven world they dont get paid for doing guided tours of an aircrafts guts.
If we all made a point of increasing a less experinced pilots understanding, I think that we would rapidly see a change overall.
