## Sequence of events

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

- Airframe/component/system failure/malfunction, takeoff - initial climb
  - warning system(other) - false indication (cause)
  - flight control system - vibration
  - aborted takeoff - performed, pilot in command
  - lack of total experience in type of aircraft, pilot in command (cause)
- In flight collision with terrain/water, landing
  - wheels up landing - performed, pilot in command

## Analysis

DURING INITIAL CLIMB, THE PLT NOTED A VIBRATION. HE WAS UNABLE TO IDENTIFY THE SOURCE & ELECTED TO LAND GEAR UP ON THE REMAINING RWY. AN EXAM OF THE ACFT REVEALED THAT THE STICK SHAKER SYS HAD BEEN ACTIVATED BY AN ELECTRICAL PROBLEM IN THE LEFT ENG NACELLE AREA. THE EXACT CAUSE OF THE ELECTRICAL PROBLEM COULD NOT BE DETERMINED DUE TO A GROUND FIRE THAT OCCURRED IN THAT AREA.
