Abstract: An airplane door sill protector is provided. The sill protector is used to fit to a sill and fuselage of an airplane to prevent damage to the fuselage. The sill protector includes an elongated body having a base joined with a lip that forms a channel to receive the fuselage of the airplane door. A first and second curved section are positioned at opposing ends of the elongated body, such that each curved section arches away from a longitudinal axis and can accommodate a curved exterior edge of the airplane fuselage. The curved sections correspond to the curve of the fuselage and, in some embodiments, are extendable to fit openings of various sizes.

Abstract: A protective cover for protecting aircraft engines is disclosed, the protective cover comprising a generally circular cross-section, a circumference, an outer side, and an inner side; said circumference being defined by a frame element having generally circular ring shape formed by a rod unit; said frame element comprising a plurality of attaching mechanisms being dispersed around said ring shaped frame, and being sized and configured to releasably attach said protective cover to an engine; said generally circular cross-section comprising one or more fabric layers contained in said ring shaped frame element. The protective cover is easily installed due to its attaching mechanisms and its breathable and durability protects the engine from damage.
