On the topic of seat pans sliding forward, I just looked at mine and there 
appears to be no way for the seat pans to slide forward on their outboard 
sides, due to the presence of the load transfer pads.  My seat pans are 
trimmed fairly close to the pads, so the seat pans can't slide forward more 
than 1/8 inch, if that far, unless the seat pan were to ride up vertically 
about 1 inch and scoot OVER the load transfer pad.

On the inboard side there's nothing to preclude the seat pan from sliding 
forward.  However, the seat pan would have to rotate around the load transfer 
pad for the inner edge to slide forward, and it looks like the console would 
keep it from rotating.  Thus it would jam up on the console at the aft, 
inboard edge, slightly cattywampus.

Still, it happened to Lorn Olsen, and I suppose it could happen again.

My current plan is to bond a 90 degree 3-BID flange onto the bottom of the 
seat pan, which would capture on the aft edge of the upper spar cap if the 
seat pan started to slide forward.  The flange would have to be long enough 
to engage the spar cap if the seat pan were merely laid on top of the 3-BID 
flange (as happened to Lorn).  The flange would not run full length -- just 
an inch or two at the inboard and outboard edges of the seat pan.  Note that 
this will not keep you from incorrectly installing the seat pan, but it will 
keep the pan from sliding forward if you do.

I haven't yet mocked it up to verify that this will work, but it seems like a 
simple retrofit, and suitable even for completed Lancairs.
