Summary
A vessel-transit near miss involved a 3.6 kg crane limit switch falling 6.5 m onto the deck without injury. The flash discusses inadequate plate design, unbalanced forces and deficient maintenance arrangements. Actions address redesign and more frequent inspection, while lessons highlight access difficulties and potentially misleading functional test results.
