Avianca Flight 671, a Lockheed Super Constellation, experienced a significant incident during its flight to Bogot  via Montego Bay. An engine malfunction at the 3rd position resulted in a diversion to Miami, followed by a replacement propeller governor. During pre-flight checks, a further defect was identified in the 2nd engine, which was rectified. The flight then departed Miami at 00:12, with the pilot as the commanding officer. Upon arrival near Montego Bay, clearance was granted for a standard instrument approach. The airfield was sighted following the procedure turn at 2000 feet, and the approach was continued visually. Upon touchdown, the plane bounced and landed inverted, 1900 feet from the runway threshold and 200 feet to the left. The probable cause was a heavy landing resulting from a structural failure in the port wing due to excessive stress transmitted through the undercarriage, exceeding the aircraft’s design limits.Avianca Flight 671, a Lockheed Super Constellation, experienced a significant incident during its flight to Bogot  via Montego Bay.
