NTSB narrative

A CESSNA MADE A LONG STRAIGHT IN FINAL APPROACH. THE AIRCRAFT'S RADIO TRANSMITTER WAS INOP. AFTERWARD THE CESSNA PIC RPTED THAT INITIALLY HE SAW THE BEECH ON A LEFT BASE. LATER HE STATED THE BEECH WAS HEADING AWAY FROM THE TRAFFIC PATTERN. WITNESSES DESCRIBED THE BEECH FLYING A NORMAL TRAFFIC PATTERN AND ARRIVING ON FINAL ABOVE & SLIGHTLY BEHIND THE CESSNA. THE BEECH BEGAN A STEEPER, FASTER DESCENT & COLLIDED WITH THE CESSNA FROM BEHIND. THE INVESTIGATION UNCOVERED INTENSE ANIMOSITY BETWEEN THE CESSNA OPERATIONS AND THE FLIGHT SCHOOL WHERE THE BEECH WAS BASED. CORPORATE PILOTS COMPLAINED ABOUT TRAFFIC PATTERN DISCOURTESY BY TWO ACFT WHOSE DESCRIPTIONS MATCHED THE ACFT INVOLVED IN THIS COLLISION. A WITNESS REPORTED HEARING THE BEECH MAKING POSITION REPORTS IN THE PATTERN. ANOTHER WITNESS STATED THAT THE CESSNA RADIO WAS RECEIVING SATISFACTORILLY.

  • 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.
