NTSB narrative
THE HYDRAULIC POWER PACK RESERVOIR WAS DEPLETED FROM A LEAK IN THE HAND PUMP SUCTION LINE, WHICH HAD BEEN CHAFED THROUGH BY INTERFERENCE WITH THE RIGHT RUDDER CABLE. APPARENTLY, THERE WAS SUFFICIENT BACK PRESSURE REMAINING TO LOWER AND LOCK THE NOSE GEAR, BUT THE MAIN GEAR NEVER EXTENDED BEYOND THE OVER-CENTER LOCKS AND COLLAPSED DURING THE LANDING ROLL. THE LANDING GEAR WARNING HORN WAS IMPROPERLY RIGGED AND NOT FUNCTIONAL. THE PILOT STATED HE OBSERVED A GEAR- DOWN INDICATION (LIGHT). THE INDICATING SYSTEM WAS FOUND TO BE PROPERLY CALIBRATED; HOWEVER, IT COULD NOT HAVE DISPLAYED A GEAR-DOWN LIGHT UNLESS THE MAIN GEAR WERE FULLY EXTENDED. THE PILOT'S STATEMENT IS IN ERROR IN THIS REGARD.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1985-02-17.
