UM Airlines — Flight UF4230

A chartered Yakovlev Yak-42D carrying Spanish peacekeepers from Afghanistan crashed into Pilav Mountain during its third attempt to land at Trabzon Airport in dense fog. The aircraft was attempting a refueling stop when it struck terrain approximately 23 kilometers (14 miles) from the airport, killing everyone on board. The accident sparked significant political controversy in Spain regarding the identification of remains and the safety of chartered military transport.

Final Report

Investigation Summary

The flight was transporting 62 Spanish military personnel (41 from the Army and 21 from the Air Force) who were returning home after a four-month tour with the International Security Assistance Force (ISAF). The crew consisted of 12 Ukrainians and one Belarusian. During the approach to Trabzon, the region was blanketed in heavy fog. The flight crew made two unsuccessful landing attempts. During the third attempt, the crew failed to properly execute the VOR/DME approach procedure for Runway 29, losing situational awareness and failing to maintain the required altitude for the missed approach segment. The aircraft impacted the slopes of Pilav Mountain at an altitude of approximately 4,600 feet, about 3.5 km east of Maçka. The investigation highlighted that the crew had exceeded their maximum duty time, and the resulting fatigue likely contributed to their inability to follow the complex instrument approach in mountainous terrain. The subsequent recovery process was marred by a major scandal in Spain when it was discovered that 21 of the bodies had been misidentified by Spanish military authorities, leading to multiple burials and high-level resignations.

Final Conclusions

The primary cause of the accident was Controlled Flight Into Terrain (CFIT) resulting from the crew's failure to follow the established VOR/DME approach and missed approach procedures for Trabzon Airport. Contributing factors included the crew's loss of situational awareness in dense fog, the challenging mountainous topography, and significant pilot fatigue. The crew had been on duty for over 22 hours, which severely impaired their decision-making and technical performance during the repeated landing attempts.
