"A:SPOILERS LEFT POSITION,Percent" Problem

[c0nnex]

Reproducible with all current Versions of P3D. Vanilla installation without any plugins/addons.

As soon as "A:SPOILERS LEFT POSITION,Percent" is added to a Datadefinition, and the loaded aircraft has no spoilers (e.g. Beech King Air 350) , the aircraft will fall through the ground as soon as it leaves the runway.
(Does not happen with FSX/FSX:SE)
