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 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 Los Mochis Airport on a cargo flight to Toluca on behalf of DHL. On descend, the crew was informed by ATC that the visibility was reduced to 1,600 metres due to foggy conditions. While on a night approach to Toluca-Adolfo López Mateos Airport, the crew descended below the MDA, probably to establish a visual contact with the ground. On short final, the aircraft struck a two metres high concrete wall located 350 metres short of runway 15 and crashed, bursting into flames. All four occupants were killed.
Probable cause:
Controlled flight into terrain on short final after the crew decided to carry out an approach under VFR mode in IMC conditions until the aircraft impacted terrain. The following contributing factors were identified:
- Poor visibility due to foggy conditions,
- Captain's overconfidence.

Circumstances:
The aircraft departed Villavicencio-La Vanguardia airport at 1206LT on a cargo flight to Mitú, carrying 12 passengers, three crew members and a load of various goods consisting of food and also 7 tons of fuel in 55 drums. After takeoff from runway 22, while climbing, the engine n°2 lost power. The captain decided to return for an emergency landing and was cleared to land on the same runway. On final approach, the airplane became unstable when the flight engineer shut down the engine n°2. The aircraft landed too far down the runway, about 1,700 feet past the runway threshold. Unable to stop within the remaining distance, it overran and came to rest against an embankment, bursting into flames. Four passengers were killed while 11 other occupants were injured. The aircraft was destroyed.
Probable cause:
The following findings were identified:
- Wrong approach configuration on part of the crew,
- Poor approach planning and execution, causing the aircraft to be unstable on short final,
- The landing speed was excessive and the aircraft landed too far down the runway,
- Unnecessary shut down of the engine n°2, causing the hydraulic systems of the main brakes to be unserviceable,
- Late application of the brakes after touchdown.
