Incident
On final approach to Daegu Airport, the flight crew did not execute the approach checklist and consequently failed to select the landing gear down. During the approach, an alarm activated in the cockpit. The crew interpreted the alarm as erroneous and pulled the corresponding circuit breaker, silencing the alert. Despite this, the crew did not verify the status of the three landing gear lights, which remained red, and continued the approach. The aircraft touched down on its belly and slid to a stop.
Evacuation and Damage
All 127 occupants evacuated from the aircraft. Among them, seven passengers sustained minor injuries. The aircraft sustained substantial damage and was assessed as beyond economical repair.
Investigation
Investigators determined that the landing gear had not been extended because the crew omitted the approach checklist and forgot to select the gear down. The alarm that sounded was a legitimate warning of the gear-up condition, but the crew disabled it. The continued approach without confirmation of gear extension led to the belly landing.
Probable Cause
The official probable cause stated: "Belly landing after the crew failed to follow the approach checklist and forgot to select gear down."
