## Sequence of events

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

  - aborted takeoff - performed, pilot in command (contributing factor)
  - exhaust system,turbocharger - output low (cause)
- Overrun, takeoff - aborted
- Nose gear collapsed, takeoff - aborted
  - terrain condition - ditch (contributing factor)
  - terrain condition - soft (contributing factor)
  - landing gear,nose gear - overload
  - landing gear,nose gear - failure,total
- Fire, standing
  - landing gear,normal brake system - overtemperature

## Analysis

THE COMMERCIAL CORPORATE PLT HAD DEPLANED HIS PASSENGERS AND WAS BEGINNING THE SECOND LEG OF A CORP/EXEC FLIGHT. DURING GROUND RUN THE PLT DETECTED A MANIFOLD PRESSURE LOSS ON THE LEFT ENGINE. THE PLT ABORTED THE TAKEOFF AND APPLIED HEAVY BRAKING. THE AIRCRAFT OVERRAN THE RNWY, CROSSED DRY DRAINAGE DITCH AND WENT THROUGH THE AIRPORT BOUNDARY FENCE. THE NOSE GEAR COLLAPSED IN SOFT SAND AND THE PROPELLERS CONTACTED THE TERRAIN. A POST CRASH FIRE IN THE LEFT MAIN BRAKE WAS EXTINGUISHED BY THE PLT. A POST ACCIDENT INSPECTION REVEALED EVIDENCE THAT THE LEFT ENGINE EXHAUST SYSTEM HAD SEPARATED FROM THE TURBOCHARGER INLET DURING ACCELERATION.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
