Summary
Investigates a lifeboat launch accident aboard RRS Sir David Attenborough that caused minor injuries to three crew. The report examines an interlock that failed to reset, likely corrosion-induced piston-rod seizure, omitted checks and maintenance, incomplete davit installation, and shortcomings in operating procedures and crew familiarisation.
