NTSB narrative

SHORTLY AFTER PASSING WATSON INTERSECTION INBOUND TO TUSCON, AZ THE OUTBOARD TIP OF ONE PROPELLER BLADE SEPARATED. THE PLT TURNED THE MAGNETO SWITCH OFF AND SLOWED THE ACFT UNTIL THE PROPELLER STOPPED ROTATING. HE THEN EXECUTED AN EMERGENCY LANDING SHORT OF THE ARPT. THE ACFT WAS LANDED IN A HARD PACKED DIRT AREA. METALLURGICAL EXAMINATION OF THE REMAINING BLADE STUB REVEALED A FATIGUE FAILURE.

  • 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.
  • API snapshot SHA-256: 0b612b4b7c9b31d156108bf1bdaa55c170282f01f12b3d29bc093a87efa4f891; retrieved 2026-09-21T17:39:57.691Z.
