CF188762 Hornet - From the Investigator
Report / February 15, 2021 / Project number: CF188762 - E Category
Location: Bagotville, Québec
Date: 9 November 2020
Status: Investigation Ongoing
On 9 November 2020, a CF188’s ejection seat waist restraints were found disconnected after shutdown from an aborted mission.
The occurrence started during an active air defence scramble at dusk. While strapping in and simultaneously starting the aircraft the pilot noticed that the leg restraint lines were not attached to the aircraft ejection seat after clipping a D-ring into one ankle garter.
As no aviation life support equipment (ALSE) technicians were available, a non-qualified technician (non-ALSE) reattached the leg restraint lines to the ejection seat. The pilot then noticed the D-ring still attached to the ankle garter. The non-qualified technician had to disconnect the leg lines using the Manual Override handle in order to properly re-route the D-ring before reconnecting them to the ejection seat.
Once all technicians were clear of the aircraft, the pilot restarted the aircraft while continuing to strap in and then taxied to hold short of the active runway, where the mission was subsequently cancelled. Upon shutdown it was discovered by ALSE technicians that the lap belts were also disconnected at the quick release end, meaning the pilot was not properly secured in the seat.
There were no injuries or damage sustained in this occurrence.
The investigation is focused primarily on procedures and training standards for both technicians and pilots, as well as Human Factors.
