Circumstances:
The aircraft was ferried from Sweden to its new operator in Venezuela and departed Linköping Airport for Porto, carrying one passenger and two pilots. The aircraft was equipped with 13 metal cans containing fuel secured in the cabin and the fuel transfer to the structural tanks was completed via an electrical pump. While flying over France at an altitude of 5,500 feet, the right engine failed, followed shortly by the left engine. The crew reduced his altitude and attempted an emergency landing in an open field. The aircraft rolled for about 400 metres and eventually collided with trees. All three occupants were injured and the aircraft was destroyed.
Probable cause:
It was determined that both engines failed due to fuel starvation and because the fuel was not properly transferred from the cans installed in the cabin. Prior to departure, the crew calculated the hourly consumption to be 170 litres while the correct consumption was in fact 360 litres per hour.
The following contributing factors were reported:
- Poor flight preparation,
- Wrong calculation of the fuel consumption,
- Poor fuel management,
- Insufficient knowledge of the aircraft performances,
- The installation of the cans had not been approved by the Authority prior to this delivery flight.

Circumstances:
While approaching Dhaka-Tejgaon Airport at an altitude of 4,000 feet, the crew encountered technical problems with the right engine they shut down. Few seconds later, the crew was able to restart the right engine but as the temperature of the turbine increased, he shut down the engine again. This time, he was unable to feather the propeller. Due to excessive drag, the aircraft lost height and the captain attempted an emergency landing in an open field. On landing, the aircraft lost its undercarriage and came to rest. All seven occupants escaped uninjured while the aircraft was damaged beyond repair.
Probable cause:
Failure of the right engine for unknown reasons. Failure of the automatic propeller pitch control mechanism was a contributing factor.

At the time of the accident, the visibility was reduced to 50 metres due to thick fog.

Probable cause:
It was determined that the aircraft was unstable during final approach for unknown reasons and that the crew failed to initiate a go-around procedure while the landing manoeuvre was obviously missed.

Circumstances:
Archana Airways L-410 aircraft VT-ETB was operating a scheduled flight from Delhi to Kanpur civil aerodrome on 18.05.96. The flight from Delhi to Kanpur was uneventful. The aircraft took-off from Delhi with 19 persons including three flight crew. During landing, the aircraft touched down late and could not be stopped within the available runway length and went beyond the runway. The aircraft hit the boundary wall of the airport and came to halt. The aircraft sustained major damages. There was no fire and no injury to persons on board the aircraft.
Probable cause:
The accident was caused due to late touchdown at higher aircraft touchdown speed as a result of which the aircraft overshot the runway and suffered damage by impact with boundary wall.
The following contributing factors were reported:
- Wrong selection of runway,
- Overloading of aircraft,
- Non-deployment of spoilers,
- Lower visibility conditions than the required,
- Disregard of procedures, regulations and instructions on part of the pilot.
