 |
|
Wasn't there an accident with a friction fit stick? I think Van's recommends a bolt and nut through the passenger stick, just in case a right seat pilot tries to take over during a hard landing and the bounce causes the stick to come away in his/her hand.
My vote for the best location for the extinguisher is just forward of the fuel valve, on the tunnel cover. To me, the best location is wherever you find it most reachable, especially at the moment you're most likely to need it. I figured it was much more important to be able to get to it in flight, so behind either of the seats was a no-no if I'm also trying to control the aircraft. It also depends on the size! Mine's one of those small halon jobbies! Regulations here in Canada stipulate a metal bracket rather than plastic.

Oh, and never make the pilot's stick friction-fit

Seriously, there is a failure mode here that I had not considered: stick pops up and out of socket for some very strange reason, remains captive by the stick boot, end falls down into the stick cut-out in the seat pan, restricting movement of the push tubes, pilot holds pressure in a panic preventing the pinched passenger stick from being extricated. Lots of things have to go wrong here to make this happen. But I have always been paranoid about small objects like cameras or water bottles being dropped into the control stick cut-out. Even with the boot and the stick in place, it's a potential control blockage/jam. Be very careful how you and your passenger handle loose objects in your laps in flight.
