A latch arrangement may comprise a latch bolt configured to rotate about a pivot, and a shear pin coupled to the latch bolt. A counterbore may receive the shear pin whereby lateral loads may be transferred between a door panel and a frame.

A high visibility panel latch may comprise a latch handle coupled to a latch mechanism, wherein the latch handle comprises a visibility feature. The visibility features may comprise a portion of at least a first face and a second face of the latch handle. The visibility features may comprise a painted channel.

A locking system for locking a cowl to a fixed structure including first and second parts, the first part including a first hook moveable on the cowl and a first shaft fixed to the fixed structure in which the first hook is moveable between locked and unlocked positions, in which the second part includes a handle actuateable between closed and open positions, a second hook and a second shaft fixed to the fixed structure or to another cowl symmetric with the cowl, in which the second hook is moveable between locked and unlocked positions and in which the second hook is mounted where passage of the handle from the closed to open positions causes the second hook to pass from the locked into the unlocked position and vice versa, and in which the locking system also includes a transmission system to move the first hook from the locked into the unlocked position when the handle passes from the closed into the open position, and vice versa.

An aircraft nacelle is disclosed and includes a first fan cowl and a second fan cowl. An opening is defined in an exterior surface of the first fan cowl. The aircraft nacelle also includes a blade, a latch mechanism, an arm, and a linkage assembly operably connecting the arm to the blade. The blade is moveable along between a stowed position and a deployed position. The latch mechanism is moveable between a latched position an unlatched position where a portion of the latch mechanism obstructs a path of movement of the blade. The arm is unable to move from an extended position where a portion of the arm extends through the opening in the exterior surface of the aircraft nacelle into a retracted position within an interior volume of the aircraft nacelle when the blade is in the deployed position and the latch mechanism is in the unlatched position.

A latch includes a handle, a hook, a first link, and a second link. The hook is rotatably mounted to the handle at a first rotational axis. The hook includes a hook body. The hook body includes a first lateral portion and a second lateral portion. The first lateral portion is laterally spaced from the second lateral portion. The first link is laterally between the first lateral portion and the second lateral portion. The first link is rotatably mounted to the first lateral portion and the second lateral portion at the first rotational axis. The second link is laterally between the first lateral portion and the second lateral portion. The second link is rotatably mounted to the first link at a second rotational axis. The second link is configured for translation relative to the first lateral portion and the second lateral portion.

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.

An aircraft cowl arrangement may comprise a first half, and a second half rotatable between an open position and a closed position, a first seal coupled to the first half, a second seal coupled to the second half, and a latch arrangement for preventing relative movement between the first half and the second half. The latch arrangement may comprise a tie rod comprising a first end coupled to the first half, a second end, and a frame having an opening for receiving the second end of the tie rod, a latch handle rotatably mounted to the frame, and a hook operably coupled to the latch handle, wherein the latch handle is configured to move between a first position wherein the hook is engaged with the second end of the tie rod and a second position wherein the hook is disengaged from the second end of the tie rod.

A latch mechanism includes a hook-handle assembly coupled to a first panel and a clevis coupled to a second panel. The hook-handle assembly engages the clevis to secure the first panel relative to the second panel.

A latch mechanism is disclosed. In various embodiments, the latch mechanism includes a T-bolt body and a T-bolt comprising a longitudinal rod extending in a longitudinal direction from the T-bolt body and a transverse rod disposed at an end of the longitudinal rod. A safety keeper defining a load slot may be configured to receive the transverse rod whereby the T-bolt is configured to secure the T-bolt body with respect to the safety keeper.

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.
