The stall speeds listed in the XL-2 Flight Manual varied according to aircraft configuration and the bank angle, as shown in Table 1. Documenting and re-enacting transportation disasters. Fuel was observed in the fuel filter bowl, free of contamination. In July 2010, the pilot purchased VH-XLK and in December 2010 obtained a Private Pilot Licence (Aeroplane). The aircraft involved in the accident, serial number 0106, was manufactured in 2008. 50:47. Unlocking Disaster. US National Transportation Safety Board (NTSB). Post-mortem examination identified that there was no evidence of pre-existing natural disease and that the pilot most likely succumbed to impact-related injuries. Witness reports identified the wind direction as being from the north-west, and the recreational pilot reported that the wind direction and strength produced a quartering tailwind from the left when approaching to land towards the east at the landing area. The MR was issued in the instrument flight rules[7] category, however an entry by the issuing maintenance organisation advised that VH-XLK was restricted to night visual flight rules as the electrical, instrument and radio periodic inspection had not been completed at the time of MR issue.

The cause of the crash was an asymmetrical change in power and the flight crew's failure to abort takeoff. After landing there, the recreational pilot believed that the runway was not suitable for the Liberty XL-2 (VH-XLK). In most cases, there is only about 3 seconds to do all this. The recreational pilot reported that the pilot of the accident flight had significant sleep opportunity on the nights of 4 August and 5 August, but did not know how much sleep the pilot actually obtained. The aircraft had been flown on 10 previous occasions with the muffler AD pending completion. The landing area ran uphill to the east, with a southerly transverse (side) slope from left to right and was about 540 m long. 16 May, 20:29 - 21:31. No pre-impact defects were identified with the engine or aircraft structure. On May 13, 2019, a de Havilland Canada DHC-2 Beaver floatplane operated by Mountain Air Service collided with a Taquan Air de Havilland Canada DHC-3 Turbine Otter floatplane over George Inlet, Alaska, United States. Nine. Physical examination showed that the unit was intact, although had sustained some impact-related damage to the associated tubing. All videos. Readers are cautioned that new evidence will become available as the investigation progresses that will enhance the ATSB's understanding of the accident as outlined in this update. These observations were broadly consistent with the Bureau of Meteorology (BoM) forecasts and the observations at ground level. The use of flap would also lower the nose attitude and increase forward visibility. Episode 1. In slow speed situations, the selection of partial flap would allow the pilot to fly the aircraft at a lower airspeed, while maintaining a greater margin above the stall. Each of these investigations identified that the stall condition is exacerbated through mishandling of the aircraft during the stall, which can result in entry into a spin. The pilot was the sole occupant on-board the aircraft and was fatally injured. The aircraft was observed circling over an area (where cattle were not moving) then in a steep descent followed by the sound of an impact. Flying Blind. The TAF for Canberra Airport (58 km west of the landing area) for the period from 1000 indicated conditions of broken cloud at 500 ft above ground level with clear visibility and wind of 4 kt from 040°, improving to clear conditions with a wind of 12 kt from 330° by 1200. At a certain angle of attack,[8] which is a characteristic of the wing design, the flow over the upper surface of the wing separates from the surface (Figure 6). 51:56. Examining a case involving a cargo plane that crashed just moments after taking off from Miami. METAR: a routine aerodrome weather report issued at routine times, hourly or half-hourly. Both occupants received fatal injuries and the aircraft was seriously damaged. Investigation number: AO-2019-052. It has been highlighted in other accident investigation reports and guidance material that the height required to recover most light general aviation aircraft from a stall/spin condition is in the order of at least 400 ft. By operating the aircraft below 500 ft while circling the landing area, the pilot reduced an important safety margin. The nose may pitch down, the inside wing may suddenly drop, and the airplane may continue to roll to an inverted position. Sign up. An engineering team from the NTSB and a Boeing technician arrived in Indonesia to assist with the Lion Air accident investigation on 31 October 2018, two days after the Singaporean team. Air Crash Investigation. Impact signatures were consistent with witness reports, indicating that the left wing struck the ground first, followed by the propeller, engine and then the fuselage. Tab - Final ; Final . Recovery from this condition will take a considerable amount of height, the magnitude of which is dependent on the reaction time of the pilot, and the use of appropriate recovery technique. The landing area met the requirements of Civil Aviation Advisory Publication (CAAP) 92-1 (Guidelines for aeroplane landing areas) for the conduct of the operations of the Liberty XL-2, and was suitable in terms of runway distance required and landing area width. The aircraft is powered by a Continental IOF-240-B engine with a full authority digital engine control (FADEC), fuel injection control system, which produces 125 hp and a cruise speed of about 125 kt. 2 years ago | 25.5K views.

This was the first time an aircraft would use the freshly prepared landing area on the property. Episode Ep. The slower aircraft was designed for landing on unprepared areas, having a different landing gear configuration and high propeller clearance from the ground. By Jon Hemmerdinger, FlightGlobal. Episode Ep. A skilled captain manages to save his crippled aircraft and everyone on board, and then it's up to investigators to track down the microscopic culprit. A damaged iPad was recovered from the accident site. In addition ‘other findings’ may be included to provide important information about topics other than safety factors. US Department of Transportation Federal Aviation Administration 2004, Airplane Flying Handbook. The ATSB also found that the aircraft departed controlled flight after slowing and turning downwind with no flap selected. Witnesses to the accident arrived promptly to assist, however the pilot was fatally injured. Analysis of 5-second flight data with ground speed corrected for observed wind (6 kt). All the weather sources confirmed that the conditions and visibility were conducive to flight under visual flight rules.[4]. VH-XLK was equipped with a stall warning system. While conducting a right turn at low altitude, the pilot lost control of the aircraft and was unable to recover before impacting terrain. The data recovered from the card installed in VH-XLK did not contain any valid date or time data, and it stored insufficient detail to identify the accident flight. They estimated the wind at the landing area to be about 5–7 kt, and they also noted that they had experienced no turbulence during their flight. The pilot was the sole occupant and had been flying in company with another pilot. This medical certificate placed restrictions on the exercise of the pilot’s licence and required that distance vision and reading correction was to be worn whilst exercising the privileges of the licence. Although the harness was cut by emergency services, the belt tongues were secure in the belt buckle. Entertainment Website The ATSB found that while coordinating a landing clearance with air traffic control and flying a low level circuit with a close downwind and base in turbulent conditions, the pilot inadvertently allowed the airspeed to decay. Free postage. An uncoordinated (or unbalanced) turn is one where a sidewards acceleration (force) is felt during the turn due to a sideslip. 2 years ago | 20.9K views. In February 2009, the aircraft had 19.6 hours total time and was issued with an Australian certificate of airworthiness in the normal category[5] and was registered as VH-XLK. On 17 March 2013, the owner-pilot of an amateur-built scale-replica Spitfire aircraft (VH-VSF) was participating in an air display at Parafield Airport, South Australia. Calibrated airspeed (KCAS) was then calculated by correcting true airspeed for pressure changes in altitude. Browse more videos. Air Crash Investigation - Air Diasater Skies Detroit Flight 253.

From the evidence available, the following findings are made with respect to the collision with terrain involving Liberty Aerospace XL-2, VH-XLK, 9 km north-east of Braidwood, New South Wales, on 6 August 2019. the flaps were in the retracted position, consistent with the observed position of the electric flap actuator. Online Coupons and Best Deals. The pilot utilised the iPad to run an electronic navigation program, but the damage to the device precluded any on-device data download. That night, both pilots stayed at Adaminaby before departing the next day to fly around the local area before heading to Merimbula. The aerodrome forecast (TAF)[2] for Goulburn Airport (62 km north of the Braidwood landing area) for the period from 0900 included clear conditions with a wind of 12 kt from 290°. Air Crash Investigation (TGL) Follow. A pilot and one passenger were on board. That pilot advised the pilot of XLK that the landing area was undulating and not suitable for his aircraft type. Follow. It also considers some maintenance aspects associated with the aircraft. The witness also stated that the aircraft appeared to be ‘hanging off the prop’, describing VH-XLK having a slowing speed and nose-high attitude. Air Crash Investigation - Air Diasater Skies Detroit Flight 253. A large amount of guidance material has been published for pilots regarding the nature of spins and stalls, such as the guidance material provided by the US FAA mentioned above, a 2008 Civil Aviation Authority (NZ) publication titled Spin Avoidance and Recovery stated: The majority of unintentional spins occur at altitudes too low for recovery. item 6 Air Crash Investigation - Season 19 (DVD) 6 - Air Crash Investigation - Season 19 (DVD) AU $30.00 +AU $6.50 postage. At about 1126, witnesses on the ground (which included the accompanying pilot) observed XLK circling the landing area. After arriving at the landing area, the pilot circled the landing area at a height of 200–400 ft above ground level. Phase: Final report: Dissemination Read more information on this investigation phase. A Russian commercial flight ends in a fatal nosedive. The indicated airspeed (KIAS) was then calculated by applying the flight manual calibration differences at certain speeds for the Liberty XL-2, taking into consideration the position errors associated with installation. It is possible that the pilot of VH‑XLK was assessing the landing area to make up their own mind, or was potentially just conducting an overflight of the property. Racing the storm. The aircraft’s last maintenance release[6] (MR) was issued by a maintenance provider at Bankstown on 30 November 2018, at which time the aircraft had 766.5 hours total time in service. Episode Ep.

The DHC-2 broke up in mid-air with the loss of the single pilot and all 4 passengers. The pilot met a friend, who was flying a recreational aircraft, at the airstrip. The internal cabin fuel tank had ruptured and a quantity of fuel had leaked into the soil. A part of the pilot’s last aeroplane flight review required the pilot to demonstrate competency in the recognition of stall signs and symptoms, and the recovery from incipient stalls and spins. The pilot was the sole occupant and had been flying in company with another pilot and his aircraft on a social, multi-day touring flight of the New South Wales hinterland, alpine and southern coast regions. However, the software provider was able to supply remotely stored data. Training in spin avoidance must include the recognition of symptoms associated with slow flight and approach to the stall through to recovery from stall with a wing drop, Recognise and manage changes in aircraft energy state. Every time a plane crashes, the world takes notice. These findings should not be read as apportioning blame or liability to any particular organisation or individual.

The stall/spin will result in a steep pitch down and rotation towards the stalled wing. En route from Bogota to the tiny Caribbean island of San Andres, Aires Flight 8250 is rocked by a major tropical storm, and crashes just short of the runway. Entertainment Website Report. Report. 05. 17 September 2003 17 Sep 2003. Episode Ep. The operating status of the aircraft’s stall warning system could not be determined. Safety factors include ‘contributing factors’ and ‘other factors that increased risk’ (that is, factors that did not meet the definition of a contributing factor for this occurrence but were still considered important to include in the report for the purpose of increasing awareness and enhancing safety). 03. By now the pilot had turned right and the Spitfire was near the extended runway centreline and 1 km from the runway threshold at a slow speed. [12] However, the flaps were confirmed to be in the retracted position at the accident site. The landing area was oriented in an east-west direction, and the recreational pilot reported that they landed with a left quartering tailwind, uphill to the east. The wreckage was distributed over a relatively small area, with all of the major aircraft components accounted for at the site (Figure 3). The ATSB found that while making the left turn, an aerodynamic stall occurred, resulting in a significant left-wing low and nose-down attitude in close proximity to the terrain. Air Crash Investigation - Air Diasater Skies Detroit Flight 253 . The accompanying pilot landed their aircraft on a private landing area at the Braidwood property about 15 minutes prior to the arrival of VH-XLK. Playing next. Copy link. Catch Up On 7plus. At 1126:21, VH-XLK commenced a left turn over the eastern end of the landing area. Aviation safety investigations & reports Ground collision with airport infrastructure involving British Aerospace AVRO 146-RJ85, VH-NJW, Perth Airport, Western Australia, on 30 July 2019 . KIAS is the speed that would be indicated to the pilot in the aircraft. The standard empty weight of the XL-2 is about 1174 lbs (438.2 kg), however VH-XLK was fitted with a ‘factory rework kit’ which enabled the aircraft to be flown at the increased weight of 1750 lbs (793.8 kg) maximum take-off weight. Investigators examine why a Boeing 737 veered off the runway in Denver. Air Crash Investigation 20 takes you to the scene of the crash like no other show. The Liberty XL-2 flight manual, section 3, described the recovery from unintentional spins as follows: If an inadvertent spin occurs, use the following recovery procedure: • Throttle - idle• Ailerons neutral• Rudder pedals – Apply and hold full opposite rudder• Control stick – forward to break stall• Neutralize rudder – make smooth pull-up from the resulting dive• Throttle – Adjust for straight and level flight. Flying has come a long way since the Wright brothers took to the air, but it’s still not perfect. 3 September 2003 3 Sep 2003. Season 1. recorded data from an electronic flight bag on the aircraft. This included an airworthiness directive (AD) specifying a muffler inspection, and an engine oil and filter change. Featuring re-enactments and exclusive eyewitness accounts, this gripping series joins investigators as they try to determine what went wrong and how these tragedies can be prevented from happening again. Search. There was no indication of an engine problem. On 18 October 2010, a Cessna 172S aircraft, registered VH-VSK, was operating at low level near Durham Downs Homestead, Queensland. The aircraft was seen manoeuvring at low level before radio and visual contact was lost. In the absence of other physical evidence, it was possible that control inputs made by the pilot induced a stall and incipient spin at an altitude that was not recoverable. The aircraft then entered a left spin with a near vertical attitude and completed one rotation before impacting terrain. Pilots can limit their risk of losing control in flight by maintaining situational awareness of the aircraft state while conducting turns, maintaining adequate airspeed through appropriate power application during increased bank angles, and by selecting altitudes to operate at that provide sufficient height to recognise and recover from a stall. On the second orbit, the aircraft was observed to slow and begin to lose height. Submit an accident or incident notification, the flight control system was assessed for control continuity with no pre-existing defects identified, fragments of the wood propeller blades, and propeller slash marks, were located at the point of impact, the propeller blades showed evidence of rotation damage consistent with engine operation at impact, the engine, empennage and right wing were located about 20 m from the initial impact point, the left wing had separated from the fuselage and was located a short distance from the initial impact point. The aircraft crashed in a factory car park, fatally injuring the pilot and substantially damaging the aircraft. Witnesses described that, during this left turn, the left wing of VH-XLK dropped and the aircraft pitched nose-down while rotating to the left. Search. Browse more videos.
