Abstract
A sensor includes a clevis insert for reception within a first bore of a clevis. The clevis insert is configured to accommodate a latch pin. A strain sensing element is operatively associated with the clevis insert for detecting mechanical strain imparted to the clevis insert when a force acts on the clevis insert through the pin. The invention also provides a method of retrofitting a cowl latch assembly.
