What happened
During the final approach phase toward Damascus Airport, the flight crew began performing necessary checklists. During this process, they observed that the three green indicators, which signify that the undercarriage is properly deployed, were not illuminated. To ensure safety, the captain contacted the air traffic controller in the tower to verify the status of the landing gear. The controller confirmed that all three components of the gear appeared to be in the down position.
Upon making contact with the runway, the right main landing gear collapsed. This failure caused the aircraft type unnamed (implied single-unit) to slide across the tarmac for a distance of several yards before the movement ceased. While there were no injuries reported among the 22 occupants, the incident resulted in the aircraft being declared a total loss due to damage sustained during the slide.
Findings
Investigations into the incident concluded that the primary factor was the failure of the right main gear upon landing. Although the gear appeared to be extended, it had not properly locked into place, leading to its collapse under the weight of the aircraft during touchdown.
