REFLECTOR: Accident report - SQ2000

[Robin Ream]

    That was a pretty sobering read Al, but the seat problem is ubiquitous in small aircraft.  Some companies have done some pretty good research into survivability issues regarding seating, but I've seen little published about improvements even though some companies claim to have made them.  As far as our aircraft are concerned, I've seen worse seats in Cessna's because I had one collapse on me in the hangar one day, but that's certainly no endorsement either.  It would be very nice to see something more occupant friendly and safety conscious if the weight penalty was permissible, so anything you come up with would be welcome news throughout the flying community.

  Some of you may have seen this on other venues.  This is not happy reading but I post it here because of one factor that relates to our airplanes - the seats.



  You can skip the rest of the report, but note that the lack of seatback support is cited as a cause in the pilots death.  The seat is essentially the same as the Velocity.  From the first time I saw the Velocity seats I was very concerned that is provides very little support against strong forces vertically or from the rear.  Once the back support breaks there is no longer a restraint system.



  And speaking of restraint system, I also pressed the factory years ago for some test of the 5/16" bolt threaded into ¼" aluminum block as an adequate seat belt attachment; particularly for the inboard side of the front seat.



  The analysis of the 4 canardians who examined the wreckage of Paul Conner's aircraft is now available at:
