At 2110 eastern time, a Cessna T210N was ditched into Peconic Bay, near Hampton Bays, Long Island. The pilot and the four passengers suffered minor injuries and a dog was killed. The pilot said he departed East Hampton Airport and climbed to 2,000 feet, en route to La Guardia Airport, when the autopilot disengaged and the engine began to lose power. The airplane came to rest in approximately 8 feet of water, about 150 yards off shore. The airplane was recovered and, after several attempts, the engine ran at various power settings without interruption. No pre-ditching mechanical deficiencies were noted.
