## Probable cause

CONTROL MALFUNCTION OF UNDETERMINED CAUSE THAT MADE FURTHER FLIGHT INADVISABLE.

## Sequence of events

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

- Airframe/component/system failure/malfunction, takeoff
  - flight control surfaces/attachments - undetermined (cause)
- Gear not extended, takeoff - aborted
  - wheels up landing - intentional, pilot in command

## Analysis

THE PILOT STATED THAT SHORTLY AFTER ROTATION AFTER HE HAD RETRACTED THE LANDING GEAR, HE NOTED THAT THE ELEVATOR UP CONTROL WAS RESTRICTED. HE THEN REDUCED POWER ON BOTH ENGINES AND EXECUTED AN INTENTIONAL GEAR UP LANDING ON THE RUNWAY. POST ACCIDENT EXAMINATION REVEALED NO MALFUNCTION OR FAILURES THAT WOULD CAUSE THE ELEVATOR TO BE JAMMED.
