The twin engine aircraft departed Regensburg-Oberhub Airport in the morning on a flight to Mannheim City. About 15 minutes prior to arrival, the pilot cancelled his IFR flight plan and started the descent under VFR mode. On approach, at an altitude of 1,700 feet and at a speed of 110 knots, the aircraft struck tree tops and crashed in a wooded and hilly terrain located east of Dossenheim, about 15 km southeast of Mannheim Airport, bursting into flames. The aircraft was destroyed by impact forces and a post crash fire and the pilot, sole on board, was seriously injured. He died from his injuries two weeks later.

Probable cause:

The decision of the pilot to continue the approach under VFR mode in IMC conditions. The limited visibility caused by low clouds was considered as a contributing factor. At the time of the accident, the hilly terrain was shrouded in clouds. For unknown reasons, the approach speed was relatively low (110 knots).

Circumstances:

The single engine airplane departed San Juan Airport at 1138LT on a flight to Tamarindo with an intermediate stop in La Fortuna on behalf of SANSA - Servicios Aéreos Nacionales. At La Fortuna Airport, a Japanese tourist was drop off and the aircraft took off at 1205LT. About five minutes after takeoff, while cruising in IMC conditions at an altitude of 5,380 feet, the aircraft struck the slope of the Arenal Volcano. The wreckage was found about 200 metres below the summit and all 10 occupants were killed.

Probable cause:

Controlled flight into terrain after the crew continued under VFR mode in IMC conditions. The following findings were identified:
- The pilot's unsafe flying and failure to maintain adequate separation (vertical and horizontal) with mountainous terrain and not remain in VMC. Moreover, lack of timely corrective action by the crew allowed the aircraft to fly in a controlled manner and unnoticed into the ground.
- Loss of situational awareness and attention from the crew.
- Inadequate monitoring and enforcement by the pilot not flying.
- Lack of application or adherence to standard operating procedures established by SANSA.
- Using flight procedures not written or approved.
- Lack of culture regarding operational safety.

The aircraft was destroyed and all three occupants were killed.

Probable cause:

Controlled flight into terrain while completing a turn on final approach, in night conditions, towards an airport of daytime operations only, as mentioned in the Aeronautical Information Publication (AIP).

Circumstances:

The single engine aircraft departed Yeniseysk in good weather conditions on a local geophysical mission over the region of Baykit, carrying two passengers and three crew members. En route, weather conditions deteriorated and the visibility was limited due to low clouds. The crew reduced his altitude to 65 metres to maintain a visual contact with the ground. When facing trees, the pilot-in-command elected to gain height. At a speed of 115 km/h, the aircraft contacted tree tops and crashed in a wooded and hilly terrain. All five occupants were uninjured while the aircraft was damaged beyond repair.

Probable cause:

The crew continued the flight at an unsafe altitude until the aircraft contacted trees and crashed.

The aircraft was destroyed and all five occupants were killed.

Probable cause:

The pilot descended below minimum sector altitude in Instrument Meteorological Condition in hilly area.
Contributing factors were:
1. ATC Chandigarh contributed to the accident by permitting IFR flight to descend below minimum sector altitude.
2. Inadequate Supervision, Lack of Safety culture and poor pre-flight planning. Factor: Pilot: Non-adherence to standard operating procedure.
