Abstract
A system for protection of at least one aircraft door sill, including a rigid panel having shape and dimensions configured to cover and to protect the sill at least partially having an attachment face oriented toward the sill of the aircraft and configured to come to rest on the latter and a step face oriented in the direction away from the attachment face. The panel includes, on one transverse side, at least one cavity forming a housing and, on the other side, an arrangement for removably fixing to the sill. The protection system equally includes at least one bar having a shape at least partially complementary to the cavity to assure the nesting thereof. In this way the panel protects the sill and can easily be replaced: the sill is provided with a rapidly interchangeable protection system.
