Following several modifications, the aircraft was completing a test flight for a CAA certification and was carrying a NAA research engineer, one pilot and a CAA inspector. After its departure from Los Angeles-Mine Field, the twin engine aircraft flew to the northwest when an engine caught fire in flight. Out of control, the aircraft dove into the sea and crashed few miles off Malibu. All three occupants were killed.

In the early hours of February 13th, 1946, VB885, an almost new Sunderland took off from RAF Calshot on a ferry flight to Karachi. Immediately after takeoff, an engine failed and the pilot decided to return to Calshot. The first attempt at landing was aborted and the aircraft went round for another approach. However, in the dark and with apparently poor visibility, the pilot apparently misjudged his rate of descent and at 0448LT, after a flight lasting 22 minutes, the aircraft crashed into the sea 100 yards off Lee-on-The-Solent. All ten crew were killed.

The crew was performing a flight from Rearsby to RAF Melbourne, Yorkshire. As the aircraft failed to arrive, SAR operations were conducted on a large area but eventually suspended a week later as no trace of the aircraft nor the five crewmen was found. It is believed the aircraft may have crash into the Humber or maybe into the North Sea after encountering electrical problems, causing the failure of the communication (radio) systems.

Enroute, the right engine failed, followed few seconds later by the left engine. In such conditions, the captain reduced his altitude and decided to ditch the aircraft into the China Sea. On landing, the aircraft overturned and came to rest upside down. Quickly on the scene, rescuers were able to evacuate six wounded people while three passengers were killed.

Crashed while landing in the Tofino's harbor. Floats were sheared off while landing on glassy water. There were no injuries but the aircraft was written off.

The aircraft arrived at Ambon Airport at 0850LT and the captain decided to wait for another RAAF C-47 flying from Darwin to have a briefing with the other crew about the enroute weather conditions. The aircraft left Ambon at 1040LT bound for Darwin but failed to arrive. SAR operations were conducted but eventually suspended after few days as no trace from the aircraft nor the 25 occupants was found.

The crew left Banana River NAS at 1927LT on a SAR mission, looking for five TBM Avenger that did not return to their base. Three minutes after departure, the contact was already lost. Twenty minutes later, while cruising at low height, the aircraft went out of control and crashed in a huge explosion into the Sargasso Sea, about 30 miles off New Smyrna, Bahamas. On site, the rescuers did not find any survivors among the 13 occupants.

On 30 November, PB4Y-2A, Bureau Number 59777, attached to VPB 122, piloted by Lt. JG John Edgar McMillan, took off from NAS Kodiak, Alaska, for Whidbey Island carrying a crew of eight and seventeen passengers. The plane was last heard from at 1747Z reporting position on the south west leg of Yakataga, estimating the southwest leg of Sitka at 1825Z. Through the entire coastal route from Kodiak to Whidbey Island has been searched thoroughly, no trace of the plane or occupants has ever been found.

The approach to Tacloban was performed in poor weather conditions. The aircraft landed hard and after touchdown, the captain decided to go around, increased power on both engines, pull up the control column and attempted a go around. The aircraft climbed to a height of 200 feet, passed few meters from the control tower, continued over the sea and eventually crashed into the sea about a mile offshore. Rescue teams arrived on the scene about five hours later and a passenger was rescued while 16 other occupants were killed.
