Witmo,
We're MOSTLY on the same page, but the "catch all" phrases - stuff like careless and reckless, and in this case "supervision" can be, and have been exploited negatively or interpreted too far to punish those who actually did nothing wrong just because some insurance money might be available. That, and it's easy to assign responsibility (where it might be better off shared) out of sympathy or because one party is no longer available to answer questions.
Student pilots start out with a goal - to solo and become a pilot - and they should be recognize that there are consequences to failure just like those of us who are CFI's accept consequences. I started off as a student pilot having literally watched three 19 year olds stall and spin a Cessna 172 into the ground that had just taken off - probably not too different from this kid, except that they had fuel and the engine was running, they were just too aggressive - "hot dogging."
This thread's accident would not result in any improvement if all we end up doing is calling it "pilot error" totally PIC's fault, when in reality something might be learned from it especially if there might be some systemic fault in the training program he was enrolled in. If there was a training deficiency or required supervision was not given, the school or instructor deserve whatever heat they get.
I think I made it clear above that after reading the brief, I think there's a good chance that the school / instructor lose the case. The flip side is that some stuff "shouldn't" need to be documented in "minute" detail. I'm fairly certain that most instructors I've ever met - even stupid, rookie, and sloppy ones, are generally going to teach some things about checklist usage, fuel, etc... right from the start these days. If they have any kind of curriculum, syllabus, etc, it is GOING to be there. That and the fact that it was a Tomahawk school make it even more likely in my book that the student HAD been trained to some degree or another in fuel. No, this accident is not a good reason to require all flight training to be in aircraft with only a "both" switch, or some "failsafe" fuel deal as is talked about in the lawsuit, and I think that is what is annoying so many here. The student had to have been overconfident to some degree, careless, to some degree, and entirely too "trusting" of the aircraft to not be more concerned about the fuel. That's just odd. I think the case is likely frivolous, but I think they'll likely win the case with an uneducated jury. The discovery process would be interesting to read if it actually did turn up something really tangible showing that they were excessively lax in fuel training. Personally, I find the language of the case to be over the top with all of the emphasis on safe aircraft and such - as it is readily demonstrable that even "safely" maintained aircraft have mechanical failures, or dumb pilots from time to time and in today's instant digital society you'd pretty much have to live under a rock to not hear about an airplane crash.
I can't see how supervising a student's every preflight could possibly make flying less safe. Supervision doesn't have to be handholding. Many CFIs I've been around let the student preflight but still check the most important items for themselves, gas on board and caps secured, oil, control locks removed, fuel shutoff valve, etc. It's not a lack of trust but realization that having additional eyes decreases the chance of missing something critical. Flying F-111s, if we weren't pressed for time prior to launch, both my crewmate and I did the walk around separately. I trusted him and he trusted me but it was better when we both backed up each other.
I think a lot of instructors do that out of self preservation instinct since they are technically "PIC" on the flight and are responsible to have checked those items personally as PIC. It's not just a supervision responsibility. If you aren't on board the flight though, it is NOT your personal legal PIC responsibility anymore - by 91.103 it is the solo pilot's responsibility.
I will say that personally checking a student's gas on a solo flight is probably going to be something CFI's are going to have to think about doing maybe as a result of this case, but again, students SHOULD be competent to do so themselves by the time they are solo. It isn't rocket science and it's not hard to teach.
The other question of course is what constitutes "supervision" - and a lot of that is probably very open to interpretation. I would generally have been comfortable prior to this, to know the student's plan, the expected weather, duration of flight, when to expect him back, and to have just seen that the student was following his checklist and had completed it prior to departure if I knew that student had been taught how to use the checklist. Supervision obviously cannot mean "in cockpit," so there are reasonable limits to what should be expected of the CFI even in this case. The final failure wasn't the fuel, it was the stall / spin which is what is more embarrassing about the crash, except that rated pilots who have passed checkrides still do that, too.
