Kondair operated G-AVKZ PA23 Aztec for some years late '70s to the '80s. They lost a Trislander which crashed on approach to Schipol and nearly lost another when en-route EGSS over the North Sea, the pilot fell asleep and to quote the report " He was awoken by a bump, caused by the undercarriage that had struck the sea. He climbed back to 1000 feet and made a check for external damage. The right landing gear was missing. The aircraft landed at Stansted with little damage".
