The fuselage may have become warped upward or downward, thus giving the tail-plane an incorrect angle of incidence.
Two of them got between my gun and our tail-plane, so that they were safe from my fire.
Look for distortion of leading edges, main and rear spars, trailing edges, tail-plane and controlling surfaces.
He was eventually killed through the breaking of the tail-plane of his machine in descending at a flying meeting at Bournemouth.
Sometimes applied to the "tail-boom" framework connecting the tail-plane with the main lifting surface.
Stabilizer—A surface, such as fin or tail-plane, designed to give an aeroplane inherent stability.
The tail-plane may be mounted upon the fuselage at a wrong angle of incidence, in which case it must be corrected.
tail-plane—A horizontal stabilizing surface mounted at some distance behind the main lifting surface.
Now line up the centre part of the main-plane with the tail-plane.
Fuselage—That part of an aeroplane containing the pilot, and to which is fixed the tail-plane.
