A locking plate (160) for restricting rotation of a fastener (140) connecting a first component (124) of a gas turbine engine (20) and a second component (122) of a gas turbine engine (20) includes a base (162) having a planar surface (164) receivable in overlapping arrangement with a head (150) of the fastener (140). A locking portion (166) extends from the base (162). Engagement between the locking portion (166) and the first component (124) restricts rotation of the locking portion (166). A key (168) extends from the base (162) and is connectable to the fastener (140) such that the fastener (140) is not rotatable relative to the key (168) when the locking portion (166) has engaged the first component (122).
