## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Airframe/component/system failure/malfunction, approach
  - hydraulic system,line - deteriorated (cause)
  - fluid,hydraulic - leak (cause)
  - fluid,hydraulic - loss,total (cause)
  - landing gear,normal retraction/extension assembly - inoperative
  - gear down and locked - not possible

## Analysis

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.
