Summary
During a routine operational test, a crewed vessel lifeboat fell into the water after its aft suspension chain broke and the overloaded forward hook pulled out of the GRP deck. The exact chain failure cause remained uncertain; brittle failure aggravated by corrosion pitting was considered most probable. Suitable heat treatment is recommended.
