Circumstances:
The aircraft was engaged on a mail flight from London-Gatwick Airport to East Midlands Airport. During the initial descent in preparation for landing at its destination, the attendant in the cabin reported that the mechanical indicators on one of the cabin doors were showing an unlocked condition. Shortly afterwards the right hand rear door (baggage door) came open, detached from its hinge mountings and became lodged on the leading edge of the right horizontal tailplane. The aircraft became uncontrollable and went into an increasingly steep dive which terminated in several abrupt pitch oscillations. Both the mainplanes and the horizontal tailplanes were subjected to overstressing in upload which resulted in their detachment from the fuselage. The aircraft was totally destroyed and all three crew members were killed.
Probable cause:
The accident was caused by the baggage door becoming lodged on the leading edge of the right tailplane after it had opened and detached in flight. This produced changes in the aerodynamic characteristics of the aircraft which rendered it uncontrollable resulting in overstressing of the wings and tailplane leading to an in-flight structural failure. A contributory factor was the mis-rigged state of the door operating mechanism which allowed the top and the bottom pairs of claw catches to lose synchronisation. The failure of the door warning arrangements to give adequate warning of door safety was a further contributory factor.

Circumstances:
The aircraft departed London-Gatwick Airport on a charter flight (JJ130) to Rijeka, Croatia, carrying 76 British tourists and a crew of seven. While approaching runway 14 at Rijeka Airport, the crew encountered very bad weather conditions with cumulonimbus, heavy rain falls and turbulences. As the aircraft passed through the area, it was carried upwards and rolled to the right. The aircraft was now above the ILS glide slope. Some 800 meters short of the runway, at a height of 60 meters, the crew decided to continue the approach. Power was reduced and the angle of descent increased to 10°. The aircraft struck the runway surface with its right main gear at a speed of 260 km/h with 4 g deceleration force. On impact, the right wing was torn off, the airplane slid for about 760 meters and came to rest upside down, in flames. Three crew members and 75 passengers were killed. Brand new, the aircraft was totally destroyed.
Probable cause:
It is considered that the probable main cause of the accident was a heavy landing on the right leg of the main landing gear, emphasised by an irregular position of the wheels and 0.7% slope up of the runway at the point of touchdown. The Commission consider that the described deviation from the flight technique in itself, did not cause the crash of the aircraft, but that loading which resulted from the conditions under which the landing was performed made a greater contribution to the crash. However, non-adequate handling of controls of the aircraft and engines could be explained only by false perceptions (illusions) of the crew concerning the aircraft position in respect to the runway. The last minute of the flight was analysed on the basis of:
- Flight recorder oscillogram,
- Results obtained during the investigation on the flight on board of the same type of aircraft,
- Study of aerodynamic characteristics and stability of TU-134A - analysis of meteorological situation,
- Analysis of crew members' statement.
According to the opinion of the Commission this was an exceptional and complex case of many unfavourable circumstances which resulted in this catastrophe.

Circumstances:
The airplane arrived in Charleroi on January 24 and was parked there since. In June, a ferry permit was issued and on July 11, it was decided to ferry the airplane from Charleroi to London-Gatwick Airport. The pilot departed Charleroi-Gosselies Airport at 1551LT. At 1634LT, while at cruising altitude, the engine n°4 suffered vibrations and the pilot decided to shut it down. Three minutes later, the engine n°3 emitted smoke then caught fire. The pilot was able to shut it down but for unknown reason could not feather its propeller. He reduced his altitude and attempted to make an emergency landing when the airplane struck trees and crash landed in a potatoes field. The pilot was unhurt while the aircraft was considered as damaged beyond repair. The pilot's total flying hours was 8,530 with zero experience on this type of aircraft.
Probable cause:
Failure of two engines in flight due to the non-observation of the procedure published by the manufacturer regarding the engine start-up following a long standstill period.

Circumstances:
On 14 January 1969 the crew flew from Gatwick to Rotterdam and return, following which they departed on a scheduled international flight Gatwick-Genoa-Gatwick. For this flight Captain A occupied the left-hand seat as pilot-in-charge, Captain B the right hand seat as co-pilot and Captain C the centre supernumerary seat as pilot-in-command, ultimately responsible for the correct operation of the aircraft. Before leaving Gatwick Captain A briefed Captain B concerning the co-pilot duties assigned to him. Although Captain C, as pilot-in-command, did not himself formally brief Captains A and B there was no doubt that they were aware of their respective tasks. On the flight from Gatwick to Genoa the aircraft was forced, due to unfavourable weather conditions at Genoa, to divert to Milan-Linate Airport where it landed at 1430 hours. Before commencing the return flight to Gatwick the crew had to await the arrival of the passengers from Genoa. This took place at 1930 hours. During the five-hour waiting period on the ground, the aircraft APU was kept in operation to ensure cabin heating and air conditioning. While Captain C tried unsuccessfully to sleep in the aircraft, Captains A and B inspected the aircraft and found ice on the wings and tail unit. The aircraft was subsequently de-iced. Before boarding the aircraft, Captains A and B made another external inspection of the aircraft and established that there was no ice on any part of it. The result of this inspection was duly reported to Captain C. Captains A and B carried out the pre-flight checks in accordance with the company checklist and verified that the take-off weight and aircraft loading were within the permitted limits. The crew occupied the same positions as during the previous flight, Captain A being in the left-hand seat, Captain B in the right-hand seat and Captain C in the jump- seat. In view of the weather, temperature and runway conditions, the crew decided to use the 18O flap setting, Spey 2 thrust (full thrust), engine anti-icing and the APU for cabin air conditioning. V1 and Vr were established at 117 kt and V2 at 127 kt. At 2018 hours, after clearance from Linate ATC, the engines were started and engine anti-icing selected "ON". There was a considerable layer of snow along the sides of the taxiways and runway, but they themselves were clear and usable. In view of the isolated patches of slush or water on the runway, Captain A considered it essential for the engine igniter switches to be selected "ON" during the entire take-off. At 2028 hours the aircraft was cleared to enter runway 18 and, after receiving the latest information concerning visibility and wind, it was cleared for take-off at 2031 hours. Before the brakes were released, a check was made of engine P7 pressures and of the other engine instruments which were found to be normal. At about 80 kt Captain A took over the aircraft's control column. The airspeed indicators showed regular acceleration and Captain A stated that just before 100 kt the engine instruments were also registering normally. V1 and Vr were called and the aircraft was rotated into the initial climbing attitude; immediately after or during this manoeuvre, a dull noise was distinctly heard by all the crew members. This noise was variously described by them as: "not like a rifle shot, not like the slamming of a door or something falling in the aircraft but more like someone kicking the fuselage with very heavy boots, an expansive noise covering a very definite time span with a dull non-metallic thud". The bang was immediately associated by the crew with the engines. After looking at the TGT gauges, and observing that No. 1 engine was indicating a temperature 20°c higher than that of No. 2 engine, Captain C said: "I think it's number one" or wards to that effect, and after a brief pause "throttle it". On receipt of Captain C's comment Captain A closed the power level of No. 1 engine. During or just after the explosion, he had completed the rotation manoeuvre and the aircraft was climbing at 12O of pitch with reference to the flight director. As a precaution, after closing No. 1 power lever he reduced the angle of climb to 6O. At the same time the co-pilot (Captain B) who had reached for the check list and was looking for the page relating to an engine emergency, became aware of a sharp reduction in the aircraft's acceleration; he noticed that the undercarriage was still down and he retracted it immediately. According to the crew the aircraft reached a maximum height of 250 ft, after which a progressive loss of momentum became evident. A maximum speed of 1401145 kt was achieved immediately after rotation, but it fell to 127 kt after No. 1 engine had been throttled back, These figures were consistent with those subsequently derived from the flight recorder. The crew said that the stick-shaker operated three times between 125 and 115 kt. The co-pilot had a vague recollection that the stick-push and the warning klaxon operated during the critical phase before impact. The pilot-in-charge remembered vaguely that someone said "raise the flaps", but no crew member remembers doing so or making the re traction. On looking out of the aircraft the crew saw the ground and the obstructions close at hand and realized that contact of the aircraft with the ground was inevitable and imminent. Captain A controlled the aircraft extremely well during the touchdown; the aircraft slid along the snow-covered surface, passing over small obstructions, and came to a halt 470 m from the point of first contact with the ground (see Fig. 1-11. The co-pilot operated both engine fire-extinguishers and Captain C ordered the pilots to leave the aircraft immediately via the side windows. During the ground slide an orange glow was seen to light up the glass panels of the windows for a short time. There was no fire. After closing No. 1 power lever, Captain A remembered having ordered the shutdown drill for this engine but he could not say for certain whether this wae dme. It was established, however, that Captain B closed both the HP cocks at the first sensation of ground contact.
Probable cause:
The accident must be attributed to a combination of factors following a compressor bang/surge in No. 2 engine immediately after take-off and the aircraft crashed because the crew, after fully closing No. 1 throttle in error, failed to recognize their mistake and, in addition, were not aware that the thrust of No. 2 engine had also been partially reduced after an inadvertent displacement of the relevant throttle lever. The following findings were reported:
- A segment of the HP turbine seal of No. 2 engine caused a compressor bang/ surge which led the crew to think that there was a serious engine malfunction. The loss of thrust attributable to this defect was negligible,
- Tests have shown that there were no defects or failures of the engine fuel system or fuel controls which could be associated with the loss of thrust over and above that resulting from the deliberate throttling of No. 1 engine,
- N° 1 engine was throttled back after an erroneous order or piece of advice and its throttle lever was pulled rearwards rapidly,
- The major loss of thrust in No. 2 engine was probably due to the displacement of the throttle lever by a crew member and to the fact that its partially open position remained unnoticed during the period of confusion preceding the emergency landing,
- The incorrect diagnosis of a malfunction of No. 1 engine after the bangleurge can be attributed to the hasty intervention of the pilot-in-command and this could be attributed to fatigue, aggravated by the long duty period,
- In rapidly throttling back No. 1 engine, the pilot-in-charge promptly executed without question what he thought to be an order instead of waiting until a greater height was reached and then taking any appropriate action,
- The judgement and actions of the pilot-in-charge were influenced by the presence of an experienced pilot designated as pilot-in-command, although the latter's specific task was the supervision of the co-pilot,
- If the aircraft pilot-in-command had been seated at the controls, he might have acted correctly; similarly, if he had been responsible solely for the supervision of the co-pilot and had not been designated as pilot-in-command, the pilot-in-charge would have had a wider and more responsible field of action and would very probably have complied with the company's prescribed drills.

Circumstances:
The accident occurred on a scheduled passenger flight from Frankfurt when the aircraft was making an ILS approach for a night landing on Runway 27 at Gatwick Airport. The weather was clear except that freezing fog persisted in places including the Gatwick area. The runway visual range (RVR) at Gatwick was 100 metres. The approach was commenced with the autopilot coupled to the instrument landing system (ILS) but after the glide-slope had been captured the commander who was at the controls, disconnected the autopilot because the "stabiliser out of trim" warning light illuminated. At the outer marker the flap setting was changed from 1° to 30° and shortly afterwards the rate of descent increased and the aircraft descended below the glide-slope. Some 200 feet from the ground the pilot realised that the aircraft was too low and initiated a missed approach procedure. The aircraft began to respond but the descent was not arrested in time to avoid a collision with trees and a house that destroyed both the aircraft and the house and set the wreckage on fire. 48 occupants as well as two people in the house were killed. 14 others were injured. The aircraft was totally destroyed by impact forces and a post crash fire.
Probable cause:
The accident was the result of the commander inadvertently allowing the aircraft to descend below the glide slope during the final stage of an approach to land until it was too low for recovery to be effected. The following findings were reported:
- The deceptive nature of the weather conditions led the commander to an error of judgment in deciding to make an approach to Gatwick,
- The commander's decision to conduct an approach was not in itself a cause of the accident,
- Incorrect flap configuration at glide-slope interception led to a temporary out-of-trim condition during the automatic approach and the illumination of the stabilizer "out-of-trim" warning light,
- The commander interpreted the "out-of-trim" warning light as indicating a possible malfunction and disconnected the auto-pilot,
- Out-of-sequence and late selection of 30° flaps from 15° while the-aircraft was being flown manually resulted in an increase in the rate of descent, causing the aircraft to go rapidly below the glide-slope,
- The commander did not become aware of the deviation from the glide-slope until it was too late to effect a full recovery,
- The pilot's attention was probably directed outside the aircraft at the critical time in an attempt to discover sufficient visual reference to continue the approach rather than to the flight instruments,
- Monitoring by precision approach radar would have warned the pilots of the deviation in time, if corrective action was taken promptly, to avoid the accident.

Circumstances:
After a touch-and-go landing at Gatwick Airport, the right main gear didn't lock up. The gear was recycled and the pilot then checked the gear visually and the gear appeared to be fully retracted. On gear extension for the next landing, the right main gear warning light remained on. The gear was recycled several times, but without success. Other attempts (high g turns, using the hand pump, and touching the runway) also failed. It was then decided to make a wheels-up landing on a foam carpet at Manston.
Probable cause:
The starboard undercarriage pin had fractured and fallen out of its housing. This permitted the assembly to drop under its own weight and, as a result it was mechanically impossible for the up-lock catch to disengage from the pin on the undercarriage leg.

Circumstances:
The pilot, sole on board, was completing a ferry flight from Nice to London-Gatwick. While descending to Gatwick Airport in VFR mode, the pilot encountered poor weather conditions with rain falls and turbulences. While flying in clouds, he lost control of the airplane that plunges into the earth and crashed in a field. The aircraft was destroyed and the pilot was killed.
Probable cause:
The aircraft collided with high ground when the pilot was attempting to navigate at low altitude in poor visibility. Turbulent airflow in the lee of a ridge may have been a contributory factor. Investigators did not find any topographic maps for the UK in the aircraft. The pilot probably did not recognise the seriousness of the deteriorating weather situation in southern England until he crossed the coast and had to fly at low altitude to remain in visual contact with the ground.
