## Sequence of events

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

- In flight collision with terrain/water, landing - flare/touchdown
  - wheels up landing - intentional, pilot in command (contributing factor)
  - landing gear,normal retraction/extension assembly - disabled (cause)
  - landing gear,emergency extension assembly - disconnected (cause)

## Analysis

THE PLT STATED THAT UPON ARRIVAL AT HIS DESTINATION HE COULD NOT GET HIS LANDING GEAR TO EXTEND. HE THEN RETURNED TO OPA LOCKA AIRPORT WHERE HE INTENTIONALLY LANDED WITH THE GEAR UP. POST CRASH INVESTIGATION OF THE ACFT REVEALED THAT THE LANDING GEAR WOULD NOT COME DOWN NORMALLY DUE TO THE DOWN LIMIT MICRO SWITCH BEING STUCK IN THE OPEN POSITION ALLOWING NO ELECTRICAL POWER TO ACTIVATE THE GEAR MOTOR TOWARD THE DOWN POSITION. ALSO THE GEAR COULD NOT BE MANUALLY CRANKED DOWN BECAUSE THE DRIVE CHAIN ON THE EMERGENCY SYSTEM WAS DISCONNECTED.
