What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
N190RF, a FW-190 entered the pattern at Chino airport via an overhead approach with a right break to enter the right downwind leg rwy 26R. On the base leg, the pilot noticed that the left main landing gear was still in the up position (note: a visual indicator pin projects from the top of the wing and is visible to the pilot from the cockpit). The pilot levelled off and contacted the tower to inform them of his landing gear issue.
The pilot advised the tower that he needed to be off frequency for thirty seconds to communicate with ground personnel at the museum. The Chino tower directed him to orbit north of the airport. After consulting with museum ground personnel, the pilot pulled the manual emergency gear release, saw three green landing gear lights and contacted tower, landing safely without further incident. Prior to landing, at the pic's request, another aircraft in the pattern visually confirmed that the aircraft's landing gear were all down.
