Learjet 31, 35, 36

0

The FAA is proposing the adoption of a new AD applicable to certain Learjet Model 31, 31A, 35, 35A (C-21A), 36, and 36A airplanes. This proposal would require modification of the drag angles of the fuselage and engine pylons to gain access to the shear webs of the forward engine beams; repetitive inspections of the shear webs of the forward engine beams for cracks; follow-on actions; and modification/repair of the shear webs of the forward engine beams, as necessary, which would terminate the repetitive inspections. The FA claims this action is necessary to prevent significant structural damage to the engine pylons, possible separation of the engines from the fuselage, and consequent reduced controllability of the airplane. All comments must be received by Dec. 29, 2003.
