Kingsley - thanks for your message. I thought about that , but I 
think I'd need clearance from an inspector to proceed with that.

I'd only get about 1mm or less by doing that - they're pretty close 
to the screw heads already, although any extra clearance would be 
welcome.

All the CM flanges around the seat area (and the ply thigh-support 
ribs) mate with brown foam areas on the lower fuselage moulding - it 
covers all the central bottom area of the lower moulding (see the 
pictures attached to the first posting). The only CM bottom flanges 
NOT resting on foam are the outboard and rear edges of the seat pan, 
although the one at the port side is wide enough to catch the foam at 
its inboard edge.

Yes - see above.

Yes. But the module doesn't lower into that position naturally; only 
if pressure is applied at the back of the seat pan does the CM 
distort to allow that flange to contact the plain glass area of the 
fuselage floor.

>Hope I have made SOME sense Rowland

Yes, I think we are on the same wavelength, but I'm still a bit puzzled.

Rowland
