Circumstances:
With an auxiliary fuel tank system installed, the pilot filled the tanks and departed. A few minutes later, he noticed fuel on the floor of the cabin, and tried to reach an airport. However, the fuel fumes were so strong he elected to land in an open field. After touchdown, the airplane passed through a ditch the pilot had not observed from the air. The nose landing gear collapsed and the airplane nosed over. An airborne witness reported the pilot exited the airplane after about 5 minutes, and about 5 minutes later, the airplane caught fire and burned. The post crash fire consumed the cabin. In an interview, the pilot reported that he had not initiated use of the auxiliary fuel tank system when the accident occurred. He also reported he could not see where the fuel was coming from. The investigation revealed the tank installation did not match the FAA Form 337, the instructions for use of the ferry tank system were inadequate, and the pilot had reported that the auxiliary fuel pumps were secured to a board which was not secured to the airplane.
Probable cause:
An inadequate auxiliary fuel tank installation which resulted in a leak of undetermined origin.

Circumstances:
The RégionnAir flight took off from Port-Menier at 23:34 for an IFR flight to Seven Islands. The crew decided to carry out a straight-in GPS approach to runway 31. However, there is no published GPS approach for that runway. The descent from cruise flight into the airport was started late, and the aircraft was high and fast during the approach phase to the NDB. From an altitude of 10 000 feet at 9 nm from the NDB, the rate of descent generally exceeded 3000 fpm. The aircraft crossed the beacon at 600 feet asl. For the last 30 seconds of flight and from approximately 3 nm from the threshold, the aircraft descended steadily at approximately 850 fpm, at 140 to 150 knots indicated airspeed, with full flaps extended. The captain coached the first officer throughout the descent and called out altitudes and distances. The GPWS "Minimums" activation sounded, consistent with the decision height selection of 100 feet, to which the captain responded with directions to continue a slow descent. The last call was at 30 feet, 1.2 seconds before impact. Eight seconds before impact, the GPWS voice message "Minimums, Minimums" activated. The aircraft continued to descend and struck trees in a near-level attitude, in an area of rising terrain. A post-crash fire destroyed the wings, the right engine, and the right midside of the fuselage. The cabin area remained relatively intact, but the cockpit area separated and was crushed during the impact sequence. The Beechcraft in question was a brand new aircraft, registered just 2 months earlier. This accident was RégionnAir's second Beech 1900 loss in 1999; on January 4 an accident happened on approach to St. Augustin River. No one received fatal injuries in that accident however.
Probable cause:
Findings as to causes and contributing factors:
1. The pilot flying did not establish a maximum performance climb profile, although required by the company's standard operating procedures (SOPs), when the ground proximity warning system (GPWS) "Terrain, Terrain" warning sounded during the descent, in cloud, to the non-directional beacon (NDB).
2. The pilot flying did not fly a stabilized approach, although required by the company's SOPs. The crew did not carry out a go-around when it was clear that the approach was not stabilized.
3. The crew descended the aircraft well below safe minimum altitude while in instrument meteorological conditions.
4. Throughout the approach, even at 100 feet above ground level (agl), the captain asked the pilot flying to continue the descent without having established any visual contact with the runway environment.
5. After the GPWS "Minimums, Minimums" voice activation at 100 feet agl, the aircraft's rate of descent continued at 850 feet per minute until impact.
6. The crew planned and conducted, in cloud and low visibility, a user-defined global positioning system approach to Runway 31, contrary to regulations and safe practices.
Findings as to risk:
1. At the time of the approach, the reported ceiling and visibility were well below the minima published on the approach chart.
2. Because the runway was not equipped with a reporting runway visual range system, flying the NDB approach was allowable under the existing regulations.
3. The crew did not follow company SOPs for the approach and missed-approach briefings.
4. Both crew members had surpassed their maximum monthly and quarterly flight times and maximum daily flight duty times. They were thus at increased risk of fatigue, which leads to judgement and performance errors.
5. The first officer likely suffered from chronic fatigue, having worked an average of 14 hours a day for the last 30 days, with only 1 day of rest.
6. Transport Canada was not aware that the company's pilots were exceeding the flight and duty times.
7. The company operations manager did not effectively supervise the flight and duty times of company pilots.
8. The captain had not received the mandatory training in pilot decision making or crew resource management.
Other findings:
1. The emergency locator transmitter activated on initial impact but ceased to transmit shortly thereafter when its antenna cable was severed.

Circumstances:
The airplane impacted the terrain approximately 2,065 feet south of the departure end of runway 22. Damage to the cockpit section of the wreckage indicated a nose down crush angle of approximately 80 degrees. The wreckage path was on a 208 degree heading, and the distance from the initial impact to the location of the empennage was about 142 feet. The cockpit and cabin were destroyed by post impact fire. Examination of the engines and propellers revealed no preexisting failures or conditions that would have prevented normal operation. The engines exhibited indications of rotation, and the witness marks on both sets of propellers were consistent with the propellers operating in the governing range at impact. Control continuity was established from the right aileron, elevator, and rudder. Witnesses reported the airplane seem to be operating normally during taxi and takeoff, but that it entered a steep left bank after clearing a 100 foot powerline located about 1,800 feet from the departure end of runway 22. After entering the steep left turn, the nose of the airplane dropped and the airplane impacted the ground. There was no evidence in the airplane's maintenance records of any annual maintenance inspection since August, 1997, although an airframe and powerplant mechanic reported that he had completed an inspection on June 30, 1999. There was no record in the airplane's maintenance records of compliance with five airworthiness directives applicable to the airplane.
Probable cause:
The pilot's failure to maintain adequate airspeed, which resulted in a stall, inflight loss of control, and collision with the ground.

Circumstances:
The aircraft took off from Arusha Airport (ARK) at 12:35 hours for a circuit training. It was carrying one instructor, a pilot trainee and three passengers. The aircraft was flying VFR. The instructor said that he intended to execute nine touch and go circuit operations, three of which were to be performed with 42° flaps, another three with 18° flaps and the rest with zero degree flaps. The first six circuits were performed uneventfully. Before initiating the first flapless landing the instructor ordered the trainee to extend his approach and establish a six-mile final to runway 09. When the aircraft was established on the final for runway 09 the instructor saw that the aircraft was a bit too low and ordered the trainee to adjust his approach. After 5H-PAB was established on the approach slope the instructor advised the trainee to call when he needed props fully forward (setting propellers into full coarse pitch). This he subsequently did and the instructor, aware of the relatively high aircraft speed for the configuration advised the trainee to be careful on the flare in order to avoid the possibility of the tail skid hitting the ground. When the aircraft was flared, the tail skid hit and scraped the ground followed by the belly and the nose underside section. After sliding for 164 metres the aircraft came to rest on the runway with the engines still running. The instructor carried out the emergency shut down checks and evacuated the aircraft. It was only after touchdown that the crew realised that they had belly landed. The commander then proceeded to select reverse thrust. There was no fire and none of the occupants was injured. The instructor said that he had forgotten to lower the landing gear because of his preoccupation with the rate of descent and the execution of the flapless flare. The pilot under instruction testified that he had concentrated too much an the technical side of flying to the point of forgetting to call for the gear down selection. There was only one checklist in use in the cockpit which was contained in a book and this was being used by the instructor. The instructor testified to have used the checklist for the first six landings. The checklist was not used for the accident landing. None pilot of the pilots reported to have heard the landing gear horn.
Probable cause:
Failure of the crew to follow the approach checklist and to lower the landing gear.

Circumstances:
The aircraft departed Tianjin on a cargo flight to Moscow with intermediate stops in Irkutsk and Perm, carrying a load of 49,750 kilos of various goods and seven crew members. At Irkutsk-Intl Airport, 38 tons of fuel were uplifted and the crew calculated 30,040 kilos for the cargo, giving a total weight of 170 tons, about 4 tons below the MTOW. During the takeoff roll, after a course of 2,000 metres, at a speed of 225 km/h, the captain started the rotation. The aircraft lifted up and flew for about 4 seconds when the captain requested gear up. At a speed of 250 km/h, the aircraft passed the runway end and adopted a 16° angle of attack. Then the aircraft' speed decreased when the flight engineer reduced the power on all four engines and activated the thrust reverser systems on both left engines n°1 and 2. The aircraft rolled to the left, collided with a building containing an electrical transformer and came to rest 1,476 metres past the runway end, bursting into flames. All seven occupants were injured, two seriously. The aircraft was destroyed.
Probable cause:
It was determined that the total weight of the aircraft at the time of the accident was 198-200 tons which means 24-26 tons above MTOW. The cargo manifest showed a total weight of 49,750 kilos of various goods upon departure from Tianjin Airport but only 30,040 kilos upon departure from Irkutsk Airport while no cargo was unloaded. The following contributing factors were identified:
- A miscalculation of the mass and balance,
- Poor flight planning,
- Poor crew coordination.

Circumstances:
During takeoff, the twin-engine airplane was observed to roll left, pitch nose down, and impact terrain shortly after the pilot reported to ATC that he had a problem. Witnesses reported that the left engine was producing black smoke during the takeoff roll. One witness stated that the airplane had slowed to approximately 60-70 mph prior to rolling to the left. A mechanic, who worked on the airplane prior to the accident, stated that the pilot reported being unable to maintain manifold pressure (MP) with the left engine. The mechanic found that the left engine's rubber interconnect boot, which routes induction air between the turbocharger controller elbow and the fuel servo, was 'gaping open.' The mechanic reseated the boot and tightened the clamp. The pilot flew the airplane and reported no problems. During a second flight, the pilot reported that the left engine was again unable to maintain MP. Prior to the accident flight, the pilot informed the mechanic that the 'hose had slid off again' and that it had been reinstalled and he 'felt sure it was o.k.' A witness stated that he saw the pilot working on the left engine the morning of the accident. At the accident site, the left engine's interconnect boot was found disconnected. The clamp securing the boot was not located. No other preimpact anomalies were found with the engines, propellers, turbochargers, or fuel servos.
Probable cause:
The pilot's failure to maintain the minimum controllable airspeed. A factor was the disconnected rubber interconnect boot, which resulted in the partial loss of left engine power.
Final Report:
