Abstract: An aircraft assembly includes a keeper, a latch and a lock. The latch includes a handle and a hook structure operatively coupled to the handle. The hook structure is engaged with the keeper when the handle is in a closed position. The hook structure is disengaged from the keeper when the handle is in an open position. The lock includes a catch, a lever and a spring. The lever is configured to rotate about an axis between a locked position and an unlocked position. The lever is aligned with the catch locking the handle in the closed position when the lever is in the locked position. The lever is misaligned from the catch unlocking the handle from the closed position when the lever is in the unlocked position. The spring biases the lever axially along the axis in a direction towards the handle.

Abstract: A nacelle for a gas turbine engine includes a fixed nacelle portion, a cowl panel, and a latch assembly. The fixed nacelle portion extends circumferentially about an axial centerline. The cowl panel is axially adjacent the fixed nacelle portion. The cowl panel is moveable relative to the fixed nacelle portion between an open position and a closed position. The latch assembly includes a first latch portion and a second latch portion. The first latch portion is mounted to the cowl panel. The first latch portion includes a pin configured for translation along a pin axis between an extended pin position and a retracted pin position. The second latch portion is mounted to the fixed nacelle portion. The second latch portion includes a pin guide. The pin guide is configured to receive and engage the pin with the pin in the extended position and the cowl panel in the closed position.

Abstract: A latch mechanism is provided that includes a latch housing, latch keeper, and a latch hook adjustment assembly. The latch hook adjustment assembly includes a latch frame, latch handle, hook member, bearing block, a nut, and a spring member. The latch frame has a front wall, an interior wall, and a forward cavity. The hook member has a partially threaded shaft. The bearing block has a flange, indexing features, and a bore. The flange has opposing first and second side surfaces. The indexing features project outwardly from the second side surface and are disposed adjacent the bore. The nut has first and second axial end surfaces, a threaded nut bore, and index cavities disposed in the first axial end surface adjacent the nut bore. The bearing block, nut, and spring member are disposed in the forward cavity. The latch hook adjustment assembly is disposable in engaged and disengaged configurations.

Abstract: A nacelle may comprise an inlet and a fan cowl aft of the inlet. The fan cowl may include a fan cowl panel configured to rotate between an open position and a closed position. The nacelle may further comprise a securement retainer including a first portion coupled to an interior surface of the fan cowl panel and a second portion coupled to an aft inlet flange of the inlet. The first portion of the securement retainer may be configured to engage the second portion.
