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:
A United States Air Force Boeing T-43A (USAF designation for the Boeing 737-200) was destroyed after impacting a hillside during an NDB approach to Dubrovnik Airport, Croatia. All 35 on board were killed. The aircraft was engaged in a mission to fly United States Secretary of Commerce Ron Brown and a delegation of industry executives around the region for visits. The party was to be flown from Zagreb to Tuzla and Dubrovnik before returning to Zagreb. Operating with a call sign of IFO21, the accident aircraft departed Zagreb at 06:24 hours. The crew landed at Tuzla at 07:15 after an uneventful flight. The passengers deplaned, and the aircraft was then repositioned to Split because of insufficient ramp space at Tuzla to park the aircraft for the duration of the visit. At 12:47, the aircraft landed at Tuzla, where the passengers reboarded. The accident flight departed Tuzla for Dubrovnik at 13:55. After crossing Split at 14:34 the flight was cleared to descend from FL210 to FL140. Further descent clearance was given to FL100. After the aircraft reached FL100 at 14:45, south of Split VOR, Zagreb Center transferred control to Dubrovnik Approach/Tower. The controller cleared IFO21 direct to the Kolocep (KLP) NDB. After opposite-direction traffic had been cleared, IFO21 was cleared to descend to 5000 feet. At 14:52, the crew told Dubrovnik Approach/Tower that they were 16 NM from the airport. They were cleared to descend to 4,000 feet and told to report crossing the KLP beacon. At 14:53, the aircraft crossed KLP, which was the Final Approach Fix (FAF), at 4100 feet and began the approach without approach clearance from Dubrovnik Tower. At that point the aircraft was slightly high and fast and not completely configured for the approach, as it should have been. At 14:54, the copilot of IFO21 called Dubrovnik Approach/Tower and said, "We’re inside the locator, inbound." IFO21 was then cleared for the NDB approach to runway 12. The aircraft tracked a course of 110 degrees after crossing KLP, instead of tracking the published course of 119 degrees. The aircraft maintained this track from KLP to the point of impact. The accident aircraft descended to 2200 feet which was consistent with the published minimum descent altitude of 2,150 feet. At 14:57, the aircraft impacted a rocky mountainside approximately 1.7 NM to the left (northeast) of the extended runway centerline and 1.8 NM north of the approach end of runway 12 at Dubrovnik Airport.
Probable cause:
Controlled flight into terrain. The following findings were reported:
- The command failure to comply with directives that required a review of all instrument approach procedures, not approved by the Defense Dept,
- Preflight planning errors, combined with errors made during the flight made by the aircrew,
- Improper design of the Dubrovnik NDB.
