The NTSB's narrative final · quoted from the NTSB record

During cruise flight, about 6,000 feet, the pilot radioed '. . . I seem to have an engine problem, I am about facing and uh looking at Weymouth Airport right now. I'm not declaring an emergency at this moment, but I do need to about face.' The controller advised the pilot that a nearby airport was closed. The pilot elected to proceed to another airport. The pilot radioed that the engine's oil pressure and temperature were '. . . in the right zone . . . .'; he later radioed 'We have no power. I have oil on the windshield.' The airplane was unable to glide to the airport. The pilot then ditched along the shore line.
