Cessna 120/140/170 Replacement Cowl Latches
The cowl latches (4 per aircraft) installed on Cessna 120, 140, 140A, 170, 170A and the 1952 version of the 170B was a trunk latch type device consisting of a two component catch assemble riveted to the upper cowl door and an eight component latch assembly riveted to the lower section. Security of closure depended upon a very slightly over center toggle action and a spring clip that retained the handle. As the components wore and spring tension deteriorated, owners and maintenance personnel have sometimes added tabs drilled for safety pins or simply drilled holes in the handle for the inclusion of sheet metal screws to keep the handle in place. Replacement assemblies are available at over $260 per latch....
That is over $1000 per airplane!
The replacement latch we offer consists of a three component upper latch and a two component receptacle for the lower cowl utilizing a standard Camloc fastener. It installs in the cowling in the same openings as the original, using the same rivet holes. Should someone later, in the interest of retaining authenticity, wish to reinstall the original style latch, he may do so by simply removing the rivets and replacing the latch assembly. No modification of the cowl proper is required.
The replacement latch is available with either a 'wing' type fastener, a Phillips head fastener, or a Slotted head fastener.
