Britten-Norman Islander

Shortly after takeoff from The Pikany Indian Reserve Airfield, while in initial climb, the twin engine aircraft lost height, collided with trees and crashed in a wooded area located on km from the airstrip. The aircraft was destroyed and all five occupants were killed, among them Indian Kayapo who were flying to Novo Progresso to have urgent care.

At approximately 1830 hrs on 3 November 2013 the operator’s duty pilot received a request that the aircraft should be dispatched to carry out a search. The volunteer crew-members were alerted and made their way to the airport. Weather conditions in the Channel Islands were poor, with a southerly wind gusting up to 41 kt, turbulence, rain, cloud below 1,000 ft aal, and visibility of 3 to 6 km. On arrival at the aircraft’s hangar, the crew was established, consisting of a pilot, search director, and three observers. They donned immersion suits and life jackets and prepared for flight. The search director obtained details of the search request, which was to search for two fishermen near Les Écréhous (a group of rocks in the English Channel approximately 5 nm north-east of the north-eastern corner of Jersey). Some evidence suggested the men were in a small dinghy; other information was that they were in the water. The men were reported to be alive and communicating by mobile telephone. One crew-member carried out pre-flight preparations, although he did not check the fuel quantities or carry out a water drain check. When interviewed, he recalled having reported to the pilot that he had not checked the fuel. The aircraft was then pulled out of its hangar and the search director explained the details of the search request to the pilot and other crew-members. Bearing in mind the weather, the fact that it was dark, and the fishermen’s predicament, the pilot recognized the need for “a lot of urgency” about the task. In the context of the operation, he regarded the task as being routine, but the weather not so. The pilot “walked round” the aircraft, though he did not carry out a formal pre-flight inspection; it was the organization’s custom to ensure that the aircraft was ready for flight at all times. The technical log showed that the aircraft was serviceable, with no deferred defects, and that the wing tanks contained 55 USG each side and the tip tanks, 18 USG each side. The search director recalled asking the pilot whether he was content to fly in the prevailing conditions, and that the pilot stated that he was willing to fly. The crew boarded the aircraft. The observer in the front right-hand seat had recently obtained a Private Pilot’s Licence and this influenced the decision for him to be placed next to the pilot. The pilot reported that he carried out a “fairly rapid” start, although the normal pre-departure sequence was interrupted while a problem with switch selections, affecting the functioning of the search equipment in the aircraft’s cabin, was resolved. The pilot obtained clearance from ATC to taxi, enter the runway, and take off when ready. He described that he carried out engine power checks during a brief back-track, checking the magnetos and propeller controls at 2,100 rpm, before carrying out pre-takeoff checks. He did not refer to the written checklists provided in the aircraft but executed a generic set of checks from memory. Following an unremarkable takeoff, in the strong crosswind , the pilot corrected for drift and established a climb towards a cruising altitude of 900 ft. When interviewed, he described the conditions as being “awful” and “ghastly”, with turbulence from the cliffs contributing to occasional activation of the stall warner, even though the speed was “probably 100 plus knots” . At 900 ft, the aircraft was “in the bottom” of the cloud, which was unhelpful for the observers, so the pilot descended the aircraft to cruise at 500 or 600 ft, flying by reference to the artificial horizon, and making constant control inputs to maintain straight and level flight. He stated that, although he would normally have begun checking fuel flow, mixture settings, etc, shortly after establishing in the cruise, he found that the conditions required him to devote his full attention to flying the aircraft. As the aircraft passed north abeam the western end of Jersey, the rain and low cloud continued and the turbulence worsened, The pilot gained sight of red obstacle lights on a television mast on the north side of the island but had few other visual references. The pilot noticed a change in an engine note. He immediately “reached down to put the hot air on” which made little difference; the observer recalled that the pilot checked that the mixtures were fully rich at this time. The right-hand engine rpm then began surging. The pilot made a quick check of the engine instruments, before applying full throttle on both engines, setting both propellers to maximum rpm and beginning a climb. The observer noticed that the fuel pressure gauge for the right-hand engine was “going up and down” but did not mention this to the pilot; the pilot did not see the gauge indication fluctuating. Around this time the pilot switched the electric fuel pumps on. The pilot turned the aircraft towards Jersey and made a MAYDAY call to ATC; the search director made a similar call on the appropriate maritime frequency. These calls were acknowledged, and a life boat, on its way to Les Écréhous, altered course towards the aircraft’s position. Although the pilot was “amazed” at how few lights he could see on the ground, he perceived what he thought was the runway at Jersey Airport, and flew towards it. The aircraft reached approximately 1,100 ft amsl. The right-hand engine then stopped. The pilot carried out the shut-down checks, feathering the propeller as he did so. The aircraft carried on tracking towards Jersey Airport, descending towards the north side of the island. Some moments later, the left-hand engine’s rpm began to fluctuate briefly before it also stopped. The pilot later recalled being “fairly certain” that he “was trying to change tanks” but acknowledged that he could not recall events with certainty. He trimmed the aircraft for a glide, still heading towards the airport at Jersey, but with very limited visual references outside the cockpit. The crew-members prepared the cabin for a ditching or off-airport landing; the observers in the rear-most seats considered how they might deploy the aircraft’s life raft (stored behind their seats) should a ditching occur. The pilot’s next recollection was that the automated decision height voice call-out activated (he had selected it to announce at 200 ft radio height). He switched the landing lights on and maintained a “reasonable speed” in anticipation of landing or ditching. One crew-member recalled the pilot calling “brace, brace, brace”, while another recalled being instructed to tighten seat belts and brace. No brace position had been set out in the operations manual, or rehearsed in training, and the responses of the crew-members to this instruction varied. The pilot glimpsed something green in front of the aircraft, and flared for landing. The aircraft touched down and decelerated, sliding downhill and passing through a hedge. With the aircraft now sliding somewhat sideways, it came to a halt when its nose lodged against a tree, with significant airframe damage. The pilot made various cockpit selections safe and all the occupants vacated the aircraft, with some difficulty. The search director became entangled in his headset lead as he egressed but freed himself. The front seat occupants experienced difficulty because their door could not be opened. They climbed over the search director’s desk and vacated the aircraft via the door adjacent to the search director’s position (the rear-row observers simultaneously opened the pilot’s door from the outside). The pilot and crew made their way to nearby habitation where they were subsequently assessed by an ambulance crew; none were injured. The search director returned to the aircraft with fire-fighters, to ensure that pyrotechnics and the self-inflating life raft on board the aircraft did not pose a hazard. In his very frank account of the flight, the pilot acknowledged that a decision to turn back soon after departure would have been justified by the weather conditions. He added that before the engine power changed, his workload was already very high, on account of the task and conditions.

The commercial, instrument-rated pilot of the multiengine airplane was conducting a newspaper delivery flight in night visual meteorological conditions. After two uneventful legs, the pilot departed on the third leg without incident. Radar data indicated that, after takeoff, the airplane flew over open water at an altitude of about 100 to 200 ft toward the destination airport and then climbed to 2,400 ft. Shortly thereafter, the pilot performed a 360-degree left turn, followed by a 360-degree right turn while the airplane maintained an altitude of about 2,400 ft, before continuing toward the destination airport. Less than 2 minutes later, the airplane began a rapid descending left turn and then collided with water. The wreckage was subsequently located on the sea floor near the airplane's last radar target. Both wings, the cabin, cockpit, and nose section were destroyed by impact forces. The wreckage was not recovered, which precluded its examination for preimpact malfunctions. The airplane had been operated for about 25 hours since its most recent inspection, which was performed about 3 weeks before the accident. The pilot had accumulated about 1,650 hours of total flight experience, which included about 1,100 hours in the accident airplane make and model. Although the pilot conducted most of his flights during the day, he regularly operated flights in night conditions. The pilot's autopsy did not identify any findings of natural disease significant enough to have contributed to the accident. In addition, although toxicological testing detected ethanol in the pilot's cavity blood, it likely resulted from postmortem production.

The twin engine aircraft departed Chihuahua-General Fierro Villalobos Airport at 1352LT on a flight to Zacatecas, carrying four passengers and one pilot. It continued to the south at an altitude of 11,500 feet and a speed of 120 knots. The flight was uneventful until the pilot started the descent to Zacatecas-General Leobardo C. Ruiz. when the left engine lost power then failed shortly later. The pilot reduced his altitude and attempted an emergency landing when the aircraft crash landed in an open field located near Purisima del Maguey, some 25 km northwest of Zacatecas Airport. All five occupants evacuated safely and the aircraft was damaged beyond repair.

Few minutes after he departed Isla del Rey Airport, while overflying the bay of Panama City, the pilot informed ATC about engine problems. Unable to reach Panama City-Marcos A. Gelabert Airport, the pilot reduced his altitude and elected to make an emergency landing on the Perico Island, some 10 km south of Panama City Airport. After touchdown, the aircraft rolled for few dozen metres before coming to rest against a container. All eight occupants escaped uninjured while the aircraft was damaged beyond repair.

On approach to runway 18 at Okiwi, New Zealand, the aircraft encountered windshear on short final as the pilot reduced power to land. The pilot was unable to arrest the descent rate and the aircraft landed heavily. Damage was caused to both landing gear oleos and one brake unit, with rippling found on the upper and lower skin of each wing. One passenger sustained a back injury, which was later identified as a fractured vertebra. The pilot was aware of fluctuating wind conditions at Okiwi and had increased the approach speed to 70 knots as per company standard operating procedures. The pilot reported that despite this, the airspeed reduced rapidly and significantly at 10 to 15 feet agl, leaving little time to react to the situation.

The twin engine aircraft departed Los Roques Island Airport Runway 07 at 1132LT on a charter flight to Caracas, carrying four passengers and two pilots. During initial climb, the crew was cleared to climb to 6,500 feet. Seven minutes later, the crew informed ATC he was climbing to 5,000 feet and reported his position some 10 NM from Gran Roque VOR. While cruising at 5,400 feet at a speed of 120 knots, the aircraft entered an uncontrolled descent and crashed in the sea. SAR operations did not find any trace of the aircraft nor the six occupants and all operations were abandoned after one week. The Italian couturier Vittorio Missoni was among the passenger. In June 2013, some debris were localized at a depth of 75 meters and five bodies were found on 17OCT2013. Eventually, the wreckage was recovered on 25NOV2013.

The twin engine aircraft was engaged in an ambulance flight from La Yesca to the Zapopan Air Base, carrying two soldiers who were injured in a car crash, and one pilot. During the takeoff roll, the airplane encountered strong crosswinds and went out of control. It veered off runway to the right and came to rest in a wooded area. All three occupants were rescued while the aircraft was damaged beyond repair.

The aircraft was operating a VFR scheduled commercial air transport flight from VC Bird International Airport, Antigua (TAPA), to John A Osborne Airport, Montserrat (TRPG). The accident occurred during the aircraft’s fourth sector of the day. Prior to the accident flight, another pilot had flown two sectors in it, from John A Osborne to VC Bird and return, before going off duty. The accident pilot reported for duty at 1130 hrs, completed pre-flight preparations, and operated the aircraft to VC Bird. After the aircraft’s arrival at VC Bird, the airport closed to VFR traffic because of cumulonimbus activity and heavy rain. The airport re-opened for VFR operations shortly before the aircraft’s departure. A cumulonimbus cloud was present on the approach to Runway 07, and although the surface wind was westerly, Runway 07 was in use for departures. On board the aircraft were the pilot, three passengers, and bags weighing 150 lb. The fuel load on departure was 65 USG of AVGAS. The takeoff mass was shown on the load sheet as 5,540 lb, which was below the structural maximum takeoff weight of 6,600 lb; the performance-regulated takeoff weight at the ambient temperature of 24 °C was greater than the structural limit. The passengers and pilot travelled in a bus from the airport terminal to the aircraft. The passengers boarded the aircraft, and the baggage was loaded into the compartment behind the rear-most seats. The pilot then boarded the aircraft. The pilot was not observed to carry out a drain of the fuel system’s water traps (the operations manual did not stipulate that a drain check should be carried out). The pilot called the VC Bird Ground Movement Control (GMC) controller for permission to start engines, and was instructed to wait while the controller contacted Montserrat ATC to enquire about the weather there. The pilot then asked for surface wind information for VC Bird and was informed it was from 240° at 10 kts. The controller gave permission for start and passed the Montserrat weather, which was suitable for the operation. The pilot was instructed to taxi to holding position Bravo. The pilot contacted the Tower controller and was instructed to enter, backtrack, and line up on Runway 07. The controller described the weather observed from the Tower to the pilot, and the pilot requested a left-hand turn-out after departure. The surface wind was transmitted as from 270° at 10 kts and the aircraft was cleared for takeoff. The aircraft entered the runway at Bravo but did not backtrack. No power checks were carried out (other evidence indicated that power checks were routinely not carried out other than on each pilot’s first flight of the day). The aircraft took off, and the early part of the climb appeared normal. Analysis of the eye witness reports, and consideration of their locations and fields of view, led to a deduction that this normal climb continued to a height of between 200 and 300 ft above the ground. The aircraft then appeared to ‘sink’, losing a small amount of height without yawing or rolling, before yawing to the right, then rolling to the right, and pitching nose down into an incipient spin to the right. The surviving passenger recalled that the stall warning sounded, and its accompanying red light (which was mounted on the right-hand side of the instrument panel and in his line of sight) illuminated throughout this period and until impact. Witnesses described that the (incipient) spin continued until the aircraft struck the ground. ATC staff in the visual control room activated the airport’s crash alarm. The rescue and fire-fighting service (RFFS) responded promptly from their station; the crew of one RFFS vehicle, working on the airport, observed the accident and responded directly to it. The pilot and one passenger were fatally injured on impact. Another passenger succumbed to her injuries before she could be extricated from the wreckage, and the third passenger, who had sustained serious injuries, was taken to hospital.

On August 30, 2012, a RAC’s BN-2B-26 aircraft, registration number B-68801, contracted by Real World Engineering Consultants Inc. (Real World) to perform an aerial photogrammetry mission with a captain, a first officer and an aerial photographer on board. The flight plan was to take off from Songshan Airport, requested for instrument departure and visual flight rules to conduct aerial photogrammetry mission in Hualien and Taitung area, the aircraft planned to land at Taitung Airport after the mission accomplished. The aircraft took off at 0726, approximately 18 minutes after took off, the flight crew changed flight mode from instrument flight rules to visual flight rules. At 0827, the aircraft entered Hualien County Fenglin, Guangfu, Wanrong aerial photograph area, maintain 8,300 feet to 8,500 feet altitude and continued climbing to Jhuosi, Hualien County photo area at 0919. From 0837 to 0843, Taipei Approach informed the flight crew ‘Radar can’t cover you…..make sure maintain visual flight’. There were about 7 times communication blockage between the aircraft and Taipei Approach during 0755 to 0913 period. The Kaohsiung Approach Control contacted the aircraft at 0913:39 and lost contact with the aircraft at 0914:20 after the last communication. At 0920:55, the aircraft was at 260 degrees, 31.5 km mountain area from Yuli, Taitung and began to turn right heading 280 degrees. The last recorded Light Detection and Ranging (LIDAR) device data was 262 degrees, 35.9 km west of Yuli′s mountain area with coordinates of 23 ° 20 ′25.01 " latitude and 121 ° 01′ 50.03" longitude. At the time of the last recording, the aircraft was at 9,572 feet with about 69 knots ground speed, 250 degrees heading, the climb rate was 874 ft / min and the pitch was 23.5 degrees. At 0940, Taipei Mission Control Center (MCC) received ELT (Emergency Locator Transmitter) signals, about the same time, Japan Coast Guard informed Rescue Command Center, Executive Yuan (RCC) of the same ELT signals. After verification with Civil Aeronautics Administration, Ministry of Transportation and Communications (CAA), RCC confirmed that the aircraft had lost contact. At 0955 on September 1, 2012, the search and rescue aircraft discovered the aircraft crashed at altitude about 9,568 feet of the original forest, about 20 kilometers southwest of Jhuosi, Hualien County. Three crew members on board were killed, and the aircraft was destroyed.
