Incident Details
The nose landing gear of an aircraft collapsed upon landing. The event occurred after the pilot had extended the landing gear during the downwind leg and observed three green landing gear position lights illuminated.
Pilot Actions
The pilot visually confirmed that the nose landing gear was extended by referencing a mirror mounted on the left engine nacelle. After the main landing gear contacted the runway, the pilot began to release elevator back pressure. Subsequently, the nose landing gear collapsed when it contacted the runway.
Post-Accident Examination
An FAA certified mechanic examined the hydraulic landing gear system. The inspection revealed that the operating pressure was within manufacturer's tolerances at 850 psi, and the hydraulic fluid level was normal. The reason for the collapse of the nose landing gear was not determined.
