Method for repair of a gas turbine engine part metallic doubler and repaired part

摘要

A method and system of repairing an engine part having a cracked metal skin (42) bonded to a honeycomb core (44) includes removing a portion of the honeycomb that corresponds to a cracked portion of the metal skin. A crack in the metal skin originates from an edge of the engine part. A portion of the honeycomb is removed to form a slot in the honeycomb beginning at the edge of the part. A doubler (98) is inserted into the slot in the honeycomb and is attached to an underside of the metal skin to form a lap joint between the doubler and the metal skin. In one embodiment, the portion of the metal skin that includes the crack remains. In an alternative embodiment, the cracked portion of the metal skin is removed and a metal patch (102) is attached to the doubler such that the patch replaces the removed metal skin.
