From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

(-23) Complete loss of right side hydraulic pressure and quantity. Flight crew had to use alternate extension control lever to extend landing gear. Both main landing gear deployed, nose landing gear remained in the up and locked position. Emergency declared and proceeded to land without nose gear extension. There was no fire or fuel leakage and fire/rescue gave ok to evacuate. One pax injured on evacuation - refused medical treatment and departed airport. Initial inspection by FAA identified that "b" nut attached to check valve on rudder hydraulic power shut-off valve (p/n 3772374-5503) was completely separated from valve, causing loss of right hydraulic quantity and pressure. It is the opinion of the iic that the alternate extension control lever was not positioned in the full up position by the flight crew, allowing the gear to free fall. The handle should stay up in the spring loaded detent (ref: MD-80AMM, chapter 32-30-00, page 203). This opinion is determined by finding the extension control handle in the stowed position after landing.
