Pacific Ocean

The pilot, sole on board, was supposed to ferry the aircraft from Majuro, Marshall Islands, to Honolulu, Hawaii. About two hours into the flight, while cruising at the altitude of 7,000 feet, the pilot informed ATC about engine problems and decided to return to Majuro. Unable to maintain a safe altitude, the pilot was forced to ditch the aircraft about 320 km northeast of Majuro Atoll. A pilot who was flying in a second aircraft was able to give the exact position and the pilot was rescued 20 hours later. The aircraft sank and was not recovered.

At 1018 hours EST, on Sunday 2 October 1994, the pilot submitted a flight plan by telephone to the Melbourne Regional Briefing Office of the Civil Aviation Authority. The flight plan indicated that Aero Commander 690 aircraft VH-SVQ would be conducting a regular public transport service, flight CD 111, from Sydney (Kingsford-Smith) Airport to Lord Howe Island with an intermediate landing at Williamtown. The flight was planned to operate in accordance with instrument flight rules with a nominated departure time from Sydney of 1100 hours. The aircraft was crewed by one pilot. The aircraft departed Sydney at 1117, carrying baggage that had been off-loaded from another company service which was to operate direct from Sydney to Lord Howe Island that day. The flight to Williamtown apparently proceeded normally and the aircraft arrived at about 1140. The company had no ground-based representatives at Williamtown but the pilot was observed by other persons in the terminal building to converse with passengers before proceeding to the aircraft. No other person saw the pilot and the passengers board the aircraft. At 1206 the pilot informed Sydney Flight Service that the aircraft was taxiing at Williamtown for Lord Howe Island and that he intended climbing to flight level (FL) 210. Departure was subsequently reported as 1208 when the pilot reported tracking 060 on climb to FL230 which was the original planned cruising level. The pilot reported passing 20,000 feet on climb to FL210 at 1229 and shortly afterwards asked if VH-IBF, a company aircraft flown by the chief pilot and operating from Sydney direct to Lord Howe Island, had departed. The pilot was advised that it had departed. The radar trace showed that the climb was discontinued at 20,400 ft at 1231:22. Three seconds later the aircraft commenced descent. The last recorded radar trace for SVQ was at 19,800 ft at 1232:54. The pilot of SVQ did not report at the position ‘Shark’ at 1232 as scheduled in his flight plan, and at 1235 he notified that the aircraft had commenced a descent to FL130. At 1238, the pilot of SVQ asked Sydney Flight Service if IBF was listening on high frequency and was advised that the aircraft was not due on frequency for another 30 minutes. He requested that the pilot of IBF call him on the company VHF frequency and reported that the aircraft had just passed ‘Shark’ and he would shortly provide an estimate for the next position, ‘Shrimp’. At 1245, he provided an estimate for ‘Shrimp’ of 1310 and stated that the aircraft was maintaining FL160. No explanation of the amended level was given by the pilot or sought by Sydney Flight Service. The chief pilot subsequently stated that he contacted SVQ on company frequency at about 1240 and that the pilot of that aircraft reported a severe vibration which he thought was caused by airframe or propeller icing. He also confirmed that he had turned the propeller heat on. The chief pilot recalled that he asked the pilot of SVQ if the cockpit indication showed that the propeller heat was working normally, to which he replied ‘yes its working’. During this period, the chief pilot and the pilot of SVQ had also discussed crew rostering. Prior to contact with the chief pilot, the pilot of SVQ contacted the pilot of VH-SVV, another company aircraft which was operating a flight from Coffs Harbour to Lord Howe Island. At 1316, after SVQ had not reported at the ‘Shrimp’ position, Sydney Flight Service commenced communications checks but was unable to establish communications with SVQ directly or through any other aircraft. At 1325 an uncertainty phase was declared and the Melbourne Rescue Coordination Centre was subsequently notified at 1331. At 1401 the duty officer at the Melbourne Rescue Coordination Centre contacted the Lord Howe Island aerodrome terminal and left a message for the pilot of IBF to telephone the Centre. After the arrival of IBF at Lord Howe Island, the company managing director, who was also on board the aircraft, called the Melbourne Search and Rescue Centre at 1410 to inquire about SVQ. Arrangements were made by the company and Civil Aviation Authority search and rescue to organise search aircraft and a distress phase was declared at 1411. Subsequently, the crews of IBF and SVV reported hearing a radio transmission from the pilot of SVQ, stating that he had ‘lost it’. Attempts at the time by the chief pilot to contact SVQ were unsuccessful.

The aircraft was transferred from Los Angeles to New Zealand via Hilo and Papeete, Tahiti. En route, while cruising at the altitude of 1,500 metres, the crew encountered technical problems with the left engine and decided to divert to Christmas Island. The left engine eventually failed and as the crew as unable to maintain a safe altitude because the aircraft was heavy (load of fuel to cross the Pacific), he decided to ditch the aircraft about 150 km north of Christmas Island. The aircraft sank four hours later and was lost. All eight occupants were rescued by the crew of a merchant ship eight hours later.

During cruise flight the accident aircraft lost oil pressure in the n°2 engine. Flight could not be sustained using the remaining engine. According to the pilot, the remaining engine would overheat when power was applied. The crew descended to just above the water and tried to fly the aircraft in ground effect, but to no avail. They elected to ditch the aircraft. During the landing, the aircraft received substantial damage and was almost immediately flooded, causing the aircraft to sink. The crew escaped, but did not have time to retrieve emergency gear. They were rescued after about 20 hours in the water. Evidence revealed that the pilot did not have a pilot's certificate. No evidence could be found to indicate that the pilot had any experience in the accident aircraft or with any sea plane. Since the aircraft sank, a cause for the engine problems could not be determined.

The aircraft departed Moffett AFB on a combined survey mission over the Pacific Ocean with a second USN Orion registered 159325 carrying a crew of 13. While cruising at an altitude of 3,000 feet in marginal weather conditions, both aircraft collided and crashed in the sea. Few debris were found floating on water about 60 miles southwest of San Diego and all 27 crew members were missing and never recovered.

During cruise flight, the right engine suddenly lost oil pressure. The pilot could see that oil was coming out of the engine area. The pilot shut the engine down. Due to high gross weight, the airplane was unable to maintain altitude on the remaining engine. The airplane was ditched in the ocean and not recovered. The pilot was rescued a day later.

During a flight at night from Majuro, Marshall Islands to Cairns, Australia, the pilot requested a descent from FL190 to 12,000 feet to remove ice from the airframe. Later, he requested a climb to FL200. After starting the climb, he made a mayday call to Sydney flight service and reported the aircraft was in an uncontrolled descent. No further transmission was received from the aircraft. The aircraft was presumed to have crashed at sea, about 370 miles east-northeast of Cairns. Neither the aircraft nor the pilot was found. Thunderstorms were reported in the area and the pilot reported being in the clouds during an earlier descent to 12,000 feet. An investigation revealed the aircraft was being ferried from Tulsa, OK. A previous pilot, who flew it to Oakland, refused to continue the flight due to a cabin pressurization problem. A 2nd pilot, who was going to continue the flight, returned to Oakland and landed the aircraft in an overweight condition, which resulted in structural damage. A 3rd pilot continued the flight, making stops in Hawaii and the Marshall Islands.

The pilot reported that he ditched his DC-4 in the Pacific Ocean on the evening of december 23 after experiencing an uncontrollable n°3 engine fire at the conclusion of a training flight. The ditching occurred in dark night conditions with minimal 10 foot swells having a period of approximately 10 seconds and the aircraft was reported to have remained afloat approximately 10 minutes after the ditching. Although the flight penetrated the Pacific coastal adiz on at least 2 occasions no radar evidence corroborated the penetrations nor was there any receipt of the pilots mayday on 121.5 mhz. No wreckage has been observed along the Washington shoreline since the event. Weather conditions at 1750 hrs pst within 20 miles of the ditching were reported as measured 900 foot overcast with 1.5 miles visibilit in light rain and fog. Surface winds prevailed from the southeast yet the two pilots reportedly drifted northeast covering a distance of at least 14 nautical miles via raft in 16 hours. The board's findings surrounding this event remain undetermined.

The aircraft departed Oakland, CA at 1733 PST on a night flight to Honolulu, HI. The flight proceeded without incident until approximately 0050 PST when the pilot advised that the left engine was slowly losing oil pressure. At that time, the aircraft was at an altitude of 6,000 feet. At 0205, the pilot reported he shut down the engine and was unable to maintain 6000 feet. A descent was started. In his last transmission at 0228 PST, the pilot reported that he was at 500 feet, barely maintaining altitude. Radio contact was lost when the aircraft was approximately 500 miles east of Honolulu. At 1559, the crew of a search aircraft sighted floating debris and one body floating in that area. A marker buoy was deployed, but no recovery was accomplish. The aircraft was presumed to have been destroyed and both occupants were presumed to have been fatally injured. The aircraft crashed in moderate sea conditions with waves heights estimated at three to five feet.
