NTSB narrative
THE PLT REPORTED THE ENGINE FAILED AT 25-30 FEET AGL DURING FINAL APCH. THE PLT INITIATED AN AUTOROTATION TO THE ASPHALT SURFACE OF THE HELICOPTER PARKING RAMP. STEEL PLATES WERE PLACED ON THE PARKING SPOTS TO PREVENT RAMP EROSION. THE LEFT FRONT SKID TUBE COLLIDED WITH ONE OF THE STEEL PLATES, FRACTURING THE FRONT CROSS TUBE. THE NOSE OF THE HELICOPTER PITCHED DOWN AND THE MAIN ROTOR DISC FLEXED, SEVERING THE TAIL BOOM AFT OF THE HORIZONTAL STABILIZER. EXAM OF THE ENGINE REVEALED THE NO. 1 TURBINE WHEEL FAILED AS A RESULT OF PREVIOUS CYCLES OF HIGH TEMP (2300 DEG F).
Probable cause
FAILURE OF THE #1 TURBINE WHEEL. CONTRIBUTING TO THIS ACCIDENT WAS THE UNREPORTED OVER TEMPERATURE CYCLES OF THE ENGINE. ALSO CONTRIBUTING WAS THE UNSUITABILITY OF THE LANDING SURFACE FROM THE PRESENCE OF THE 1/4 INCH STEEL SHEETING.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
