## Sequence of events

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

- Loss of engine power, takeoff - roll/run
  - reason for occurrence undetermined (cause)
- Loss of control - in flight, takeoff - initial climb
  - directional control - reduced, pilot in command (cause)
  - airspeed - inadequate, pilot in command (cause)
  - stall/mush - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

ACCORDING TO THE PLT THE LEFT ENG LOST PWR AT ROTATION. HE COULD THEN NOT CORRECT THE LEFT GROUND TRACK DEVIATION WITH RIGHT RUDDER. TO AVOID OBSTACLES AT THE EDGE OF THE RWY HE PULLED THE ACFT OFF THE GROUND BUT THE ACFT SOON SETTLED BACK DOWN, SUSTAINING SUBSTANTIAL DAMAGE. AN ENG TEARDOWN REVEALED A SMALL HOLE IN THE FUEL CONTROLLER INLET SCREEN AND A VARIABLE ABSOLUTE PRESSURE CONTROLLER OUT OF CALIBRATION. THOSE INDIVIDUALS INVOLVED IN THE TEARDOWN STATED THAT THESE DISCREPANCIES WOULD NOT HAVE RESULTED IN THE PWR LOSS AS DESCRIBED BY THE PLT. THE REASON THE ENG LOST PWR COULD NOT BE DETERMINED.
