Event Description
On a local training flight at Surabaya-Juanda Airport, a crew was conducting a series of six landings. During the final approach of the fourth landing attempt, the landing gear alarm activated. In response, the pilot-in-command increased engine power and initiated a go-around procedure, suspecting a technical issue. Simultaneously, the copilot reduced power on both engines. This action caused the aircraft to lose speed and enter an aerodynamic stall. The aircraft struck the runway surface, veered to the right, and eventually came to rest. Both occupants escaped uninjured, but the aircraft sustained damage beyond repair.
Probable Cause
The official investigation determined the probable cause to be the crew's failure to follow the approach and landing checklist. On final approach, the pilot-in-command initiated a go-around procedure after the landing gear alarm sounded because the crew forgot to lower the undercarriage. Following poor crew coordination, the copilot cut the throttle back, causing the aircraft to stall. Additionally, the crew failed to follow the go-around procedure.
