NTSB says a plane that came to rest on one engine suffered a broken pin inside the landing gear

A broken pin might have caused a landing gear failure that left an Alaska Airlines jet resting on one of its engines last month. The National Transportation Safety Board said in a preliminary report Monday that after the pin broke, the landing gear punched through the top of the left wing. The incident happened as the Alaska Airlines jet was landing at John Wayne Airport in Santa Ana, California, on Aug. 20. The flight happened during Tropical Storm Hilary, and the pilots talked about needing to make a firm landing. But the NTSB says the touchdown force appears to have been within the airline's limits for the Boeing 737 jet.
