Incident Details
During a visual approach to runway 27L, the airplane was landed with the landing gear retracted. The landing gear was not extended at touchdown, resulting in the airplane contacting the runway surface with its propeller blades, leaving signatures on the runway.
Pilot Statements
Both the captain and first officer stated that the landing gear had been lowered over the outer marker. They reported observing three green lights, indicating the gear was down and locked, and that the warning horn did not sound prior to touchdown.
Witness Observations
Witnesses on the ground stated that the landing gear was retracted during the approach and touchdown, contradicting the pilots' account.
Post-Incident Tests
After the airplane was moved and placed on jacks, retraction and extension tests were conducted. These tests revealed that the landing gear operation was normal, as were the warning indications. Additionally, the warning horn for flaps down with gear up exhibited normal operation.
No further details from the investigation were provided. The exact aircraft type, registration, operator, date, location, time of day, and weather conditions were not specified in the source.
