Beech A100

Cracked Elevator Trailing Edge Splines

Transport Canada has received several Service Difficulty Reports describing cracking of the elevator trailing edge spline (P/N 115-610010-125). The first cracked spline was detected during an unrelated repair. Subsequent inspection by the operator revealed 10 trailing edge splines were cracked as well.

Most of the cracks extended from the rivet hole to the trailing edge of the spline and completely cracked through the spline. The cracks forward of the rivet are exposed on disassembly.

Cracks in the paint on the trailing edge are common, however, further investigation is required to determine if there is a crack.

Transport Canada recommends that owners and maintainers be vigilant while inspecting the elevator trailing edge splines for cracks on Beech A100.
