What happened
During a Joint Aviation Authority (JAA) commercial pilot checkride, the aircraft was landed with the landing gear in the fully retracted position. The student pilot reported that she had verbally completed the landing checklist but failed to notice the absence of the three green lights indicating gear extension.
The investigation
Following the incident, the aircraft was hoisted off the ground for inspection. When the landing gear selector handle was moved to the gear-down position, the landing gear extended without any anomalies. The investigation found no mechanical issues with the landing gear system that could have been associated with a pre-impact condition.
