NTSB narrative
AFTER A TOUCH-&-GO LANDING, THE FLT CREW NOTED A PROBLEM WITH THE LANDING GEAR. A CHECK OF THE HYDRAULIC SYS REVEALED A LACK OF FLUID IN THE RESERVOIR; THE PLTS WERE UNABLE TO EITHER RETRACT OR EXTEND THE GEAR. SUBSEQUENTLY, THEY LANDED THE ACFT WITH THE NOSE & RGT MAIN GEAR EXTENDED & THE LEFT MAIN GEAR IN A TRAIL POSITION. THE LEFT WING TIP, LEFT MAIN GEAR DOOR & LEFT STABILIZER WERE DAMAGED DURING THE LANDING. AN EXAM OF THE HYDRAULIC SYS REVEALED THAT A HOSE TO THE RIGHT MAIN GEAR DOOR ACTUATOR WAS LEAKING & HAD PERMITTED DEPLETION OF THE HYDRAULIC FLUID. THE HOSE WAS DETERIORATED FROM AGE.

- 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: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
