IMCA informs about an incident where a starboard wing searchlight fell into the sea, and provides lessons learned.
The incident
The starboard wing searchlight became detached from its mounting bracket in heavy weather, and fell directly into the sea, snapping the secondary tether that was in place.
Probable cause
The secondary tether was jury rigged out of a whip-check designed to contain a parting airline; it was not designed to take any loads.
