Georgetown

On the leg from Townsville to Darwin, while cruising 30 km from Georgetown, the flight engineer informed the pilot about a fuel leak on the left engine. The captain decided to divert to Georgetown Airport for an emergency landing but on final, the seaplane was unstable, banking left and right. The pilot increased power on the right engine and attempted a go around when the aircraft banked right, stalled, overturned and crashed in flames in a field located about 5 km from the airport. Five crew members were killed instantly while two others were seriously injured. One of the survivors died from his injuries few hours later.

The crew was engaged in a night maritime patrol flight and the aircraft was carrying 1,380 gallons of gasoline and 4 x 350lb Mk.41 depth charges. With a wind of 16 knots from 159°, the runway in use was 139°. Cross wind was apparently not corrected for and the plane drifted toward the left side of the runway as it continued the takeoff run. Slightly before becoming airborne, the port wing tip struck a fifteen foot vertical embankment on the left side of the runway. The outer eight feet of the port wing folded back, the plane climbed the embankment and cart wheeled over onto its back. Three bombs were thrown clear. The fourth remained in the wreckage, but did not explode. The aircraft was totally destroyed and five crewmen were killed while three others were injured.

The airplane left West Palm Beach Airport at 0030LT on a cargo flight to Georgetown, Ascension Island. While overflying the Bahamas at the assigned altitude of 9,000 feet about 90 miles east of Florida, the crew encountered an unexpected situation. The airplane became unstable and severe vibrations were noted in the tail, the stabs and the control column. In such situation, the captain decided to return to West Palm Beach but approaching Florida, the on-board situation worsened and the crew decided to abandon the aircraft and bailed out. Six crew were found alive about 10 miles east of Hollywood, Florida, while two other occupants were never found. With the autopilot engaged, the aircraft continued to the west, overflew the Gulf of Mexico for about 2,000 km and eventually came down, short of fuel, on a mountain located near General Zaragoza, Nuevo León.

While overflying the Atlantic Ocean by night, on the leg from Georgetown (Ascension Island) to Natal, while on a flight from Accra to Natal, the aircraft disappeared into the Ocean around 2300LT. SAR operations were conducted for several days but eventually suspended as no trace of the aircraft nor the crew was found. Two life vests were discovered on a Brazilian beach few days later.
