New! Flap Trailing Edge Stiffener for Cessna Aircraft
New streamline shape reduces stress cracks and improves appearance
FAA-PMA! Logbook entry only
McFarlane's stiffener does not deform the skins.
Original stiffener deforms the skins, resulting in crack inducing stress in the corrugations and around the rivet heads.
New improved fit to reduce skin stress
The new McFarlane stiffeners are accurately shaped to the same angle that the top and bottom skins come together to completely eliminate the bending stress due to riveting the skins together. This prevents stress concentrations in the skin corrugations and near the rivets, making cracks less likely.
Our new design smoothly transitions from the skin surface to a blunt trailing edge. It maintains the flap's natural airfoil shape by eliminating the unsightly bulb and resultant drag found on common trailing edge stiffeners.
