Circumstances:
The twin engine aircraft, operated by STS Avijacija (STS Aviation), departed Banja Luka on a charter flight to Tuzla, carrying two passengers and one pilot taking part to a foxes vaccination program. While cruising at low altitude, the airplane entered an area of clouds when it impacted trees and crashed on the slope of a mountain located near the Monastery of Ozren, southeast part of the Serbian Republic of Bosnia, bursting into flames. Both passengers were seriously injured and the pilot was killed.
Probable cause:
The root cause of the accident is the entry of the aircraft into the cloud at a low altitude, in conditions of increased cloudiness, which led to the impact of the aircraft in the ground. The accident is caused by inadequate preparation of the crew for the flight, deviation of the crew from the planned and approved route by location (diversion from the given route) and flight height (flight at a lower altitude than the approved one), as well as not taking timely procedures to return to the given route and flight height, as well as incorrect actions in case of encountering a deteriorated weather situation on the route under VFR flight conditions.
The accident was affected by:
a) The decision of the manager on the manner of execution of the flight,
b) Ignoring information about the meteorological situation and weather forecast,
c) Inadequate preparation of the crew for the execution of the flight at a low altitude and in conditions of fire of the meteorological situation,
d) Non-compliance with VFR rules for minimum flight height and meteorological minimum for airspace class “F” and “G”,
e) Loss of visual contact with the ground.

Circumstances:
The twin engine aircraft departed Skopje on an official flight to Mostar, carrying two pilots and seven passengers, among them Boris Trajkovski, President of the Republic of Macedonia. He was flying to Mostar with members of his government to take part to an economic conference. On approach by night and limited visibility due to marginal weather conditions, the aircraft struck the slope of a mountain located near Berkovići, about 32 km southeast of the airport. The aircraft was destroyed by impact forces and a post crash fire and all nine occupants were killed.
Probable cause:
The accident was the consequence of a controlled flight into terrain after the crew initiated the approach prematurely. The following contributing factors were identified:
- Poor approach and landing preparation and planning,
- The crew ignored ATC information about the current meteorological situation at Mostar Airport,
- The crew misinterpreted the Final Approach Fix (FAF) with the Intermediate Approach Fix (IAF), causing the aircraft to start the descent prematurely,
- The crew disengaged the autopilot system during the approach while descending in complex meteorological conditions,
- Poor crew resources management,
- Lack of crew communication,
- The crew failed to comply with SOP's,
- Failure of the pilot-in-command to maintain flight level when the aircraft reached the MDA and failure of the second pilot to give adequate assistance.
