Abstract: An improved latch with preload indicator for securing together a pair of hinged cowlings surrounding an aircraft engine. The latch comprises a hook which engages a keeper attached to one of the cowlings, a handle attached to the other cowling and mounted with the hook along a common pivot, and a hook-handle spreader spring with a free end that moves relative to and extends through the handle to provide indication of latch preload. The visual indication of the preload eliminates the need for maintenance personnel to measure the handle closing force during installation, rigging or maintenance of the cowlings.

Abstract: An automatic deflector for deflecting hot exhaust air from a bleed air exhaust port of a jet engine compressor. The deflector deflecting the hot air into the engine's fan duct when the engine is in a thrust reversal mode. The deflector prevents hot air from contacting and damaging the fan duct wall opposite the air exhaust port.

Abstract: A latch signal for mounting inside an engine cowling structure. The signal indicating when an internal latch is inadvertently left unlatched when the cowlings are closed. Further, the signal prevents adjacent cowlings from closing until the internal latch is properly secured.

Abstract: An improved latch for securing together a pair of hinged cowlings surrounding an aircraft engine. The latch is characterized by having a safety lock for engaging a hook when the latch is in a locked or latched position and also for engaging the hook when the hook has been disengaged from a latch keeper thereby allowing the operator of the latch to engage and disengage the cowlings using only one hand.

Abstract: An improved latch for aligning and securing together a pair of hinged cowlings surrounding an aircraft engine. The latch not only holds the cowlings together during thrust and reverse thrust loads, but also absorbs shear loads placed thereon by the aircraft.
