## Sequence of events

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

- Airframe/component/system failure/malfunction, approach - vfr pattern - base leg/base to final
  - landing gear,normal retraction/extension assembly - failure,total (cause)
- Complete gear collapsed, landing - flare/touchdown
  - wheels up landing - performed, pilot in command (cause)
  - emergency procedure - attempted, pilot in command (contributing factor)
  - remedial action - performed, pilot in command (contributing factor)

## Analysis

THE ACFT LANDED GEAR UP AFTER THE LANDING GEAR COULD BE EXTENDED IN FLIGHT. THE PLT STATED DURING THE APP TO ST. AUGUSTINE ATTEMPTS TO LOWER THE GEAR WERE UNSUCCESSFUL. THE GEAR DOORS WOULD OPEN AND THE HYDRAULIC PUMP WAS WORKING BUTTHE GEAR WOULD NOT EXTEND. ATTEMPTS TO MANUALLY HAND PUMP IT DOWN WERE ALSO UNSUCCESSFUL. POST CRASH INVESTIGATION SHOWED THAT THE HYDRAULIC SYSTEM HAD EVIDENCE OF WATER AND THE FLOW CONTROL MANIFOLD ASSEMBLY VALVE HAD RUSTED CAUSING THE GEAR DOORS TO OPERATE IMPROPERLY.
