Mike any preliminary thoughts on oil pressure? In a little bit over 450 hours I have had one loss of oil pressure it was due to the remote oil filter assembly accessory plate warped causing air lock..... I was fortunate to shut it off and I did a total overhaul to verify everything’s was fine this was about 18 years ago. Oil sampling and compressions all good.

I liked the firewall tearing off. Fyi, when the canard ripped off it took the header tank with it and cracked the main tank so I had a total fuel spillage.
No fire for 3 reasons. 1) had been gliding for a while and engine was off and cool. 2) landed on grass. 3) electrical design that I had not planned on. A large cable came up to the starter solenoid and was high up on the firewall, engine side. That wire stayed hot, so not great. Then I ran all the aircraft systems from a smaller hot wire that ran to a plug under the instrument panel. That plug separated in the crash basically shutting down everything.
That turned out to be a good idea.
Mike Dwyer Q200
Never met Mike, but have seen all his YouTube videos, and I too am very glad he came out of this OK.
I had similar thoughts about the canard and also the firewall. I’m expecting to receive my unbuilt kit in July and wonder if this can be treated as a learning opportunity for new builders such as myself.
I have several safety concerns about the crashworthyness as designed. I have planned to look at a ‘false floor’ to provide a flat area for the pedals and potentially conceal plumbing, wiring etc. I also feel that the attachment of the firewall bulkhead to the fuselage seems a little ‘minimal’; this crash possibly indicates that may be true. My major concern are the fuel tanks/system. Very fortunately there appears to have been no fuel spillage in this case, but from my research it appears many were not so fortunate.
Obviously a major accident is never going to have a good result; my concern is the minor accidents that have potential to have a very bad result, but could possibly be mitigated with better design or manufacturing.
Is there a case for a ‘lessons learned’ discussion?
Again, very happy Mike survived this accident and feel badly for the loss of his aircraft.
