Trabzon | Bureau of Aircraft Accidents Archives

The airplane departed Ankara-Esenboğa Airport at 2233LT bound for Trabzon. Following an uneventful flight, the crew started the approach by night to runway 11 and the landing was completed in heavy rain falls at 2325LT. After touchdown at a speed of 143 knots, the airplane rolled for about 2,400 metres then veered off runway to the left, went through a grassy area then down a steep slope. It lost its right engine and came to rest few metres above the sea. All 168 occupants evacuated safely. The right engine was sheared off and fell into the sea. According to first report, it is believed something went wrong with the right engine after touchdown (unintentional forward thrust and asymmetrical thrust).

Circumstances:

Chartered by the Spanish Government, the aircraft was completing a charter flight from Bishkek to Zaragoza with an intermediate stop in Trabzon, carrying 62 Spanish peacekeepers and 13 crew members. The 62 passengers were respectively 41 members of the Land Forces and 21 members of the Air Force who were returning to Spain following a peacekeeping mission in Afghanistan. While descending to Trabzon Airport by night, the crew encountered poor visibility due to foggy conditions. Unable to establish a visual contact with the approach lights and the runway 29, the crew initiated a go-around procedure. Few minutes later, while completing a second approach, the crew failed to realize he was not following the correct pattern for an approach to runway 29 when the aircraft impacted a mountain at an altitude of 4,600 feet. The aircraft disintegrated on impact and all 75 occupants were killed. The wreckage was found 3,5 km east of the village of Maçka, about 23 km southwest of the airport.

Probable cause:

The accident was the consequence of a controlled flight into terrain due to the combination of the following factors:
- Loss of situational awareness on part of the flying crew,
- The crew failed to comply with the Standard Operational Procedures published by the operator,
- The crew failed to follow the published approach charts,
- Implementation of a non-precision approach,
- Incorrect use of the automated flight systems,
- Inadequate training (LOFT),
- The crew descended below the MDA in limited visibility.

Circumstances:

The aircraft departed Kharkiv Airport on a charter flight to Isfahan, Iran, with an intermediate stop in Trabzon, carrying 38 passengers and six crew members. All the occupants were engineers working for Antonov and flying to Isfahan to conduct test flights on the first Iran-140, a prototype built under licence by HESA Company. While descending to Isfahan Airport by night and marginal weather conditions, the aircraft struck the slope of a mountain located 30 km from the airport. The aircraft was totally destroyed and all 44 occupants were killed.

Probable cause:

Controlled flight into terrain after the pilots failed to use properly the GPS system installed in the cockpit.

Circumstances:

While cruising at an altitude of 6,000 metres, the aircraft suffered a structural failure when the tail separated. The aircraft entered an uncontrolled descent and crashed in a wooded area located about one km from Cherkessk. The aircraft was totally destroyed upon impact and all 50 occupants were killed. The tail was found about 1,600 metres from the main wreckage. It was reported during investigations that the tail separated due to corrosion after the aircraft was operated in humid environment in Zimbabwe and DRC from 15 August 1994 till 28 December 1995.

Probable cause:

The accident was caused by the combination of the following factors:
1.Surface, without the use of instrumental control methods, by the commission's assessment of the technical condition of the An-24 RA 46516 aircraft and the subsequent unjustified issuance of a conclusion and a decision on the possibility of extending its MTO and service life;
2. Violation of the requirements of the current documents when extending the overhaul life for the An-24 RA 46516 aircraft and extending the established overhaul life without taking into account its long-term operation in a humid and hot climate;
3. Inconsistency of the regulatory documents governing the organization of work to establish and extend the resources and service life of civil aircraft (Regulation 1994) with the requirements of flight safety in modern conditions;
4. Violation of the requirements of the technology for repairing aircraft and household equipment during repairs in ARZ conditions;
5. Imperfection of technological documentation for periodic maintenance in terms of determining the corrosion and corrosion-fatigue state of the aircraft structure in hard-to-reach areas;
6. Insufficient control in the operation of hard-to-reach areas of the underground part of the fuselage in terms of determining the state of structural elements and the presence of corrosion lesions;
7. Failure to comply with the prescribed anti-corrosion measures for the structure of the aircraft during repairs at the ARP and in operation.

After the fifth bounce, the nose gear collapsed and the aircraft slid for few dozen metres before coming to rest. All 44 occupants escaped uninjured while the aircraft was damaged beyond repair. It was reported that the crew failed to prepare the flight according to published procedure and at the time of the accident, the CofG was too far aft, causing the aircraft to be unstable.
