During the aircraft acceptance check for aircraft CH148805, avionics technicians inspected the #1 Power Distribution Unit as per the Fleet Work Instructions. Terminal wire lugs T1, T2 & T3 were found unsecured. A Foreign Object Damage (FOD) check was carried out and all missing hardware for T1 lug was located just below in its cover panel. The preventive measures recommend a publication amendment, and a design change to prevent the nuts at the terminal connections from backing off when subjected to vibrations.

The aircrew were tasked as part of Operation REASSURANCE to conduct a routine surface reconnaissance mission in the Ionian Sea followed by flight deck evolutions for aircrew proficiency upon recovery to HMCS Fredericton. During this final complex manoeuvring turn to close with the ship, the aircraft did not respond as the crew would have anticipated. This event occurred at a low altitude, was unrecoverable and the aircraft entered a high energy descent and impacted the water astern the ship. The aircraft was destroyed and all six occupants were fatally injured.
