What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The aircraft was on a post test flight after an annual inspection. During the approach for landing the pilot selected gear down, at that point the pilot stated hydraulic fluid stated spraying on him and his face. He stated it was coming from under the instrument panel, left of the center pedestal. He aborted the landing and executed a go around. He selected the auto pilot on and was able to divert the hydraulic spray away from him and his face. Once the hydraulic fluid stopped spraying him he prepared for landing. The gear indicator did not show all green down and lock lights for the gear. This was verified by personal on the ground. The emergency pump did not work due to hydraulic fluid loss. It appeared the nose gear was down and locked but not the mains. On landing during roll out the main gears swung back and up partially into the wheel wells while the nose gear stayed down and locked. The pilot was able to control the plane down the center line of the runway until the last 50 feet then veered off to the left of the runway into the grass doing very minor damage to the aircraft.
