What happened
During a mission to transfer troops from Subi Point, Philippines, to the USS Constellation aircraft carrier, the Greyhound experienced a catastrophic loss of control. As the aircraft approached the naval vessel, it entered a steep dive toward the ocean surface. The impact with the water caused the airframe to disintegrate completely.
Search and rescue operations were initiated approximately 15 km from the carrier. Rescuers located an oil slick and various pieces of wreckage floating on the surface of the sea. Tragically, there were 26 fatalities in the accident, as none of the people on board survived the crash.
Findings
Investigators were unable to confirm a definitive reason for the accident due to a lack of physical evidence. However, preliminary assessments suggested that an engine failure may have led to the loss of control. During the subsequent investigation, reports emerged regarding structural issues involving the engine nacelles. As a result of these findings, the Certificate of Airworthiness for the aircraft was suspended.
