A couple of good points were made in relation to draining the fuel tanks and although I am no expert, I want to be clear on what was reported to me by the FBO just this morning as to what measures were taken during the fuel draining.
1. The bucket was plastic, but according to the chief of maintenance the bucket and the aircraft were grounded utilizing 2 grounds (one to the airframe and one to ground). I mentioned the concerns noted here on the board and he stated that they had a grounding strap designed to insure the plastic bucket was fully grounded. I have no idea what it would look like and did not ask for an example, but he was absolutely confident that the bucket was properly grounded, and from what the fire marshall has stated, he is probably right.
2. The defueling was done inside, with one hangar door open to ventilate. He mentioned that if he were looking for one specific area that he would do differently it would be to have both doors open for better ventilation. Why? See below:
3. The fire started, not in the draining fuel, but in the vapors. In fact, the original fire ball was under the fuselage on the ground away from the draining fuel. It then spread and caught the draining fuel and that was all she wrote. The current thinking at the FBO is that better ventilation (or, of course doing it outside) might have prevented the fire.
4. The source of the spark is the largest unknown at the moment. The leader in the clubhouse is, believe it or not, the creeper that the mechanic was on or the mechanic himself. It was a fairly dry day and static electricity is the current culprit du jour. Infinity is currently testing ways to insure the creepers are grounded as well.
Keep in mind that this is not a "mom and pop" shop but a Mooney, Cirrus and Cessna service center and to put it in perspective, my airplane was the cheapest in the hangar (dollar-wise, of course) by 100Ks of dollars. They certainly have done great work for me (with the exception of burning my airplane to the ground) including pre-buy, avionics and maintenance and treated me more like a turbine owner than a mid-70s piston driver. That is not to excuse what happened here, but to emphasize the fact that if a shop like this can have issues draining fuel from airplanes, your local mechanic can as well. Heck, I changed my home airport to be close to them and paid a premium to have them do my maintenance!
Interestingly, I am still considering them for my maintenance for any aircraft that I might purchase. In my mind I realize that having my airplane destroyed while in their care should require the "death penalty" for future business. But they treated me so well and their support before the incident (and, notably after the incident) was fantastic that I am still not ready to leap away from them yet. This is a dilema that I will work through over the next couple of weeks. As a note, they have offered to be my buyers agent to look for a new airplane and to do a pre-buy on any options (graitis) I might find. Good business sense on their end? Probably. But I appreciate the gesture none the less.
Thanks for everyone's notes of sympathy for my loss. But, as I tell my kids, a setback is really an opportunity as long as you keep positive. It has been a tought 2010 so far; I was laid off in January and my airplane burned to the ground in March. But I formed my own company and now make more than I did while working and I'm sure I will end up with a real nice J model (the 252 thing is probably stretching it) at the end of this. Just another opportunity to improve my lot.
