Piper PA-31-350 Navajo Chieftain

The pilot elected not to use the stored instrument flight plan, and he departed with a special VFR clearance. The flight was being followed by radar. After reaching visual flight conditions, the pilot proceeded toward his intended destination and climbed to 8,500 feet. Minimum safe altitude warning service was available, but not requested by the pilot. A review of radar data indicates that the airplane's track remained almost constant at 300° with a 160-knot ground speed. The last radar hit on the airplane occurred about 0.3 miles from where the airplane cruised into 8,500 foot msl terrain while still tracking along a northwesterly course. The accident occurred in dark, night time conditions.

At 1805 Atlantic standard time (AST), C-GNPG, a Piper Navajo Chieftain operating as Empress 204, departed Moncton, New Brunswick, on a scheduled courier flight to Bathurst. The aircraft carried a two-pilot crew, and there was no cargo on board. The aircraft proceeded direct to Bathurst at 8,000 feet above sea level (asl) and at 1820 AST was cleared by Moncton Area Control Centre (ACC) for an approach at Bathurst. The co-pilot contacted the Bathurst UNICOM and advised the operator that the crew would be flying the non-directional beacon/distance measuring equipment (NDB/DME) runway 10 approach. During the non-precision instrument approach to runway 10, the aircraft struck trees .75 nautical miles (nm) inside the Bathurst beacon and 3.75 nm from the airport. The accident occurred at approximately 1845 AST, during the hours of darkness in instrument meteorological conditions, at an elevation of 450 feet asl. Both pilots were killed.

Cargo was not weighed and weight and balance calculations were not performed. The airplane was about 321 pounds over gross. While taxiing, a witness reported seeing black smoke trailing the left engine which had been worked on the night before the accident. Two cylinders were worked on and a fuel injector nozzle was cleaned. The climb after takeoff was 'low and slow' during which the airplane rolled left, pitched nose down, and impacted the ground coming to rest adjacent to a house. Examination of each engine revealed no evidence of internal mechanical failure or malfunction. Heat damage precluded testing of the magnetos, turbocharger components, and fuel servos of each engine. Examination of each propeller revealed no evidence of preimpact failure or malfunction. The fuel nozzles from the left engine were examined which revealed that they were blocked in various places due to contaminants. After the accident the faa performed a focused inspection of the operator revealing that the cargo was not being weighed, the chief pilot of the company was in name only, and load manifests were not being kept by the company. The pilot, sole on board, was killed.

Members of a football club had planned to visit Launceston, travelling by light aircraft. Three aircraft were needed to carry the group, with all passengers and pilots contributing to the cost of the aircraft hire. One of the club members, who was a pilot, organised the required aircraft and additional pilots for departure from Moorabbin Airport on the afternoon of 17 September 1993. The operator from whom the aircraft were hired, who also employed the organising pilot as an instructor, arranged for one Piper PA-23 (VH-PAC), a Piper PA-31-310 (VH-NOS) and a Piper PA-31-350 (VH-WGI) to be available for the trip, with the organising pilot to fly VH-WGI. On the day of the flight the pilot of VH-WGI carried out pre-flight inspections, obtained the weather forecasts and submitted flight plans for all three aircraft. The flight plans for the two PA-31 aircraft were for flights operated in accordance with IFR procedures. The PA-23 was to operate in accordance with VFR procedures. The TAF for Launceston predicted 2 octas of stratocumulus cloud, base 2,000 ft and 3 octas of stratocumulus cloud, base 3,500 ft. The flight plan for VH-WGI (see fig. 2) indicated that the aircraft would track Moorabbin Wonthaggi-Bass-Launceston and cruise at an altitude of 9,000 ft. A cruise TAS of 160 kts, total plan flight time of 90 minutes, endurance 155 minutes and Type of Operation 'G' (private category flight) were specified. No alternate aerodrome was nominated and none was required. The estimated time of departure was 1730. The flight plan was submitted to the CAA by facsimile at 1529. Last light at Launceston was 1919. VH-WGI departed Moorabbin at 1817 and climbed to an en-route cruise altitude of 9,000 ft. The pilot was required to report at Wonthaggi but passed this position at 1832 without reporting. Melbourne ATC tried unsuccessfully to contact the pilot because of this missed report. Later, the Melbourne radar controller noticed the aircraft deviating left of track but was unable to make contact. Communications were re-established at 1858 when the pilot called Melbourne FS saying he had experienced a radio problem. By this time the aircraft heading had been corrected to regain track. At 1927 the pilot called Launceston Tower and was cleared for a DME arrival along the inbound track of the Launceston VOR 325 radial. The Launceston ATIS indicated 2 octas of cloud at 800 ft, QNH 1,012 hPa, wind 320° at 5-10 kts, temperature +10° and runway 32 in use. At 1930 the ADC advised the pilot that the 2 octas of cloud were clear of the inbound track, but that there was some lower cloud forming just north of the field, possibly on track. He informed the pilot that there was a chance he might not be visual by the VOR, in which case he would need to perform an ILS approach via the Nile locator beacon. The ADC contacted the airport meteorological observer at 1933, inquiring as to what the 1930 searchlight check of cloud height had revealed. He was told the observation indicated 7 octas of cloud at about 800 ft. At 1935.52 (time in hours, minutes and seconds) the ADC asked the pilot for his DME (distance) and level. The pilot responded that he was at 12 DME and 3,300 ft. The ADC told the pilot that conditions were deteriorating with probably 4 octas at 800 ft at the field. He then told the pilot he would hopefully get a break in the cloud, but then restated that if he was not visual by the VOR to make a missed approach, track to Nile and climb to 3,000 ft. At 1939.45 the pilot was again asked for his DME and level. He indicated that he was at 1,450 ft and 2-3 DME. He then also confirmed that he was still in IMC. There were three other aircraft inbound for Launceston and the ADC made an all-stations broadcast that conditions were deteriorating at Launceston, with 4 octas at 800 ft, and to expect an ILS approach. At 1940.56 the pilot stated that he was overhead the field, but did not have it sighted and was going around. At 1941.07 the pilot reported that he had the airfield in sight and at 1941.16 that he was positioned above the final approach for runway 32. Fifteen seconds later the pilot reported that he was opposite the tower and was advised by the ADC that he was cleared for a visual approach, or a missed approach to Nile as preferred. The pilot indicated he would take the visual approach and was then told to manoeuvre as preferred for runway 32. This was acknowledged at 1941.48. No further communications were received from the pilot. The ADC made a broadcast to two other inbound aircraft at 1942.32, advising that VH-WGI was in the circuit ahead of them, that it had become visual about half a mile south of the VOR, that it was manoeuvring for a visual approach and was just in and out of the base of the cloud. After the pilot of VH-WGI reported over the field, and the aircraft first appeared out of cloud, witnesses observed it track to about the south-east end of the aerodrome at a height of about 500-800 ft. It then turned left to track north-west on the north-east side of the main runway and approximately over the grass runway. The aircraft was seen to be travelling at high speed, and passing through small areas of cloud. North of the main terminal building a left turn was initiated onto a close downwind leg for runway 32. The aircraft appeared to descend while on this leg. As the base turn was started, at a height estimated as 300-500 ft, the aircraft briefly went through cloud. Some of the witnesses reported that the engine noise from the aircraft during the approach was fairly loud, suggestive of a high power setting. Late on a left base leg the aircraft was observed to be in a steep left bank, probably in the order of 60°, at a height of about 200 ft. It then descended rapidly and struck a powerline with the right wing, approximately 28 ft AGL, resulting in an airport electrical power failure at 1943.02. Almost simultaneously the left wing struck bushes. A short distance beyond the powerlines the aircraft struck the ground and slid to a stop. A fierce fire broke out immediately. Airport fire services responded to the accident and the fire was quickly extinguished. Six of the occupants received fatal injuries and the others, including the pilot, were seriously injured.

The business flight departed Lavrentya, Russia with what the pilot-in-command estimated to be 50 gallons of usable fuel on board the airplane and landed in Provideniya, Russia around 40 minutes later with about 30 gallons of fuel remaining. The plane took on an additional 30 gallons of fuel. The pilot said that he normally departed Provideniya with 120 gallons of fuel but that there was no additional fuel available. The flight departed Provideniya with what the pilot estimated to be 1 hour and 45 minutes of fuel endurance and landed in Gamble, Alaska on St Lawrence Island approximately 25 minutes later. The pilot did not dip stick the fuel tanks to verify the amount of fuel on board. The pilot did not check on the availability of fuel in Gamble. The right and left engines lost power approximately 40 minutes and 50 minutes, respectively after departing gamble. The airplane did not carry personal flotation devices for the passengers.

At about 1500 hours EST, 11 June 1993, a standard company flight plan held by the CAA at the Melbourne flight briefing facility was activated. The plan indicated that Piper PA-31-350 aircraft VH-NDU would be conducting flight OB 301, a regular public transport service from Sydney (Kingsford Smith) airport to Cootamundra NSW, with intermediate landings at Cowra and Young. The flight was planned to be operated in accordance with IFR procedures, with a scheduled departure time from Sydney of 1720. The aircraft was to be crewed by two pilots. Prior to departure, the company scheduled a second aircraft to operate the Sydney–Cowra sector. Consequently, VH-NDU was required to land only at Young and Cootamundra. At that time of the year, the 1720 departure time meant that the flight would be conducted entirely at night. VH-NDU departed Sydney at 1738 carrying five passengers, with a fuel endurance of about 253 minutes. The pilot-in-command occupied the left cockpit seat. The aircraft initially tracked via the direct Sydney to Cowra route and climbed to a cruising altitude of 8,000 feet. At 1801 the pilot reported to Sydney FIS that the aircraft was now tracking direct to Young, and would report at Riley, an en route reporting point located 62 NM from Young on the Katoomba– Young track. FIS advised the area QNH was 1003 hPa. At 1814 the pilot reported the aircraft was at Riley and estimated arrival at Young at 1835. By 1820 the pilot had reported on descent to Young, with in-flight conditions of cloud and heavy rain. Recorded radar data later showed that the aircraft passed 13.5 NM to the south-east of Riley, south of the direct Katoomba–Young track. At about 18.5 NM north-east of Rugby, the aircraft turned right and initially tracked about 280° before turning left to track direct to Young. When queried by FIS at 1836, the pilot amended the estimate for his arrival at Young to 1838. At 1842, after prompting from FIS, the pilot reported at Young that he was commencing an NDB approach, and would call again on the hour or in the circuit. Shortly after 1845 witnesses at Young aerodrome saw the lights of an aircraft, which they believed to be VH-NDU, pass low overhead after approaching from the east. Some minutes later the same aircraft was seen to pass over the aerodrome from the opposite direction and appear to climb away towards the east. On both occasions the runway and aerodrome lights were not illuminated, although the aerodrome was equipped with PAL and it was the responsibility of the pilot-in-command to activate it. At 1850 FIS advised VH-NDU of the proximity of Cessna 310 aircraft, VH-XMA, which was estimating arrival at Young at 1900. VH-XMA subsequently reported holding in visual conditions at about 8 NM north of Young. The pilot of VH-NDU reported at 1903 that he was on another overshoot at Young, about to commence another approach, and would report again at 1915. FIS provided additional traffic on Piper PA31 aircraft, VH-XML, which was also estimating Young at 1915. At about this time witnesses reported seeing the runway lights illuminate. VH-XMA then proceeded to Young and landed on runway 01 at about 1912. At 1916 VH-NDU reported in the Young circuit area and cancelled SARWATCH. A pilot witness said that the aircraft passed over the northern end of the aerodrome from a westerly direction before turning right and taking up a heading consistent with a right downwind leg for a landing on runway 01. The aircraft was then seen to turn right and pass to the south of the aerodrome before entering what appeared to be a right downwind leg for runway 19. When abeam the aerodrome the aircraft again turned right and overflew the aerodrome to enter a second right downwind leg for runway 01. Another witness thought the aircraft (VH-NDU) was significantly lower than another aircraft approaching from the east (VH-XML). Shortly after VH-NDU turned onto an apparent base leg the navigation lights were lost to sight. Almost immediately a fireball was observed, consistent with the final position of the aircraft (see figure 2). At 1918 the pilot of VH-XMA telephoned the 000 emergency services number and reported the accident to the Goulburn Ambulance Control Centre. By 1920 this information had been relayed to the Young Ambulance Service, the Young Police, and the Young SES. An off-duty Fire Brigade officer, who was waiting at the aerodrome, drove into Young and alerted the Fire Brigade at 1930. The emergency services initially travelled to Young Aerodrome but were unable to gain immediate access to the accident site, which was located on a hill some 2.2 km to the south-south-east of the aerodrome, in an area remote from roads and lighting. Access was finally gained from a road located south of the accident site. An ambulance reached the aircraft wreckage at 1952 and the crew were able to rescue and resuscitate the only survivor, who was critically injured, and transport her to the Young Hospital. She died at Camperdown Children’s Hospital at 0510 the next morning.

The pilot was conducting a scheduled passenger service flight from Port Augusta with a stop at Innamincka. A commercial pilot, travelling as a non-paying passenger, occupied the co-pilot's seat to observe the operation. Two additional passengers were on board the aircraft for the entire flight. After landing at Innamincka, the aircraft was refuelled by the pilot in command and the oil levels of both engines were checked by the observer, who experienced difficulty securing the combination oil filler cap-dipsticks. He asked the pilot for instructions and, although some advice was given, the pilot did not check the security of the dipsticks. Take-off was commenced towards the north into a 10-15 knot wind with a surface temperature of about 20 degrees C. Shortly after lift-off, at the first power reduction, the observer in the co-pilot's seat advised that there was oil seeping back along the cowl from the right side oil filler hatch. The pilot reported that he increased power to both engines but believed there was no response from the right. He began an immediate left turn to complete a circuit and attempted to secure the right engine and feather the propeller. The aircraft then began a roll to the right, the nose dropped and the aircraft impacted the ground. As the aircraft rolled right and the nose dropped, the pilot reported that he had secured the left engine and feathered the propeller. The observer in the co-pilot seat reported hearing a continuous stall warning horn as the right wing began to drop. All occupants, although injured, were able to vacate the aircraft through the main cabin door. The pilot provided assistance to the passengers and then returned to the airport to summon help.

Crashed in unknown circumstances upon landing at South Bimini Airport. The pilot, sole on board, was uninjured.

Crashed on landing for unknown reasons. Both pilots were rescued and the aircraft was written off.

Parked at Ica-Las Dunas Airport, the twin engine aircraft was stolen by three people who were able to takeoff. Shortly after liftoff, police officers shot the aircraft that crashed in a field. All three occupants were killed.
