An aircraft engine cowling comprises a first cowling portion and a second cowling portion moveable relative to each other. A cowling latch secures the first cowling portion and the second cowling portion in a closed position. The aircraft engine cowling further comprises a deflection limiter band and a deflection limiter latch moveable between an engaged state and a disengaged state for the deflection limiter band. An interlock mechanism prevents disengagement of the cowling latch while the deflection limiter latch is in the engaged state. The interlock mechanism includes a lock element moveable between a first position that prevents disengagement of the cowling latch and a second position that enables disengagement of the cowling latch. The interlock mechanism also includes an indicator paddle movable to contact the deflection limiter latch. A linkage assembly coordinates movement of the lock element with movement of the indicator paddle.
