What happened
While operating in the cruise phase of flight, the flight crew identified abnormal readings on the left engine, specifically involving high temperatures and fluctuating oil pressure. In response to these indications, the pilot executed a precautionary shutdown of the left engine.
Shortly after the first engine was shut down, the right engine began to fail, preventing the aircraft from maintaining its assigned altitude. Although the crew attempted to restart the left engine, the aircraft continued to lose altitude. The crew subsequently performed a forced landing on a beach, where the aircraft eventually came to rest in approximately five feet of water within the Atlantic Ocean.
Findings
Post-incident inspections of the propulsion systems identified mechanical failures in both engines. An examination of the left engine determined that the front master rod bearing had failed. Similarly, the investigation of the right engine revealed a failure of the aft master rod bearing.
