NTSB narrative
NEAR THE COMPLETION OF A DUAL INSTRUCTIONAL FLT WITH A PRE-SOLO STUDENT, THE CFI FOLLOWED THE PROCEDURES RECOMMENDED IN THE AIR & ANNOUNCED HIS CESSNA ACFT'S POSITION OVER THE CTAF STATING HIS INTENTIONS & IDENTIFYING HIS LOCATION ON THE 45 DEG, ENTRY & DOWNWIND LEGS. THE CFI FAILED TO TRANSMIT HIS POSITION ON THE FINAL APPROACH LEG, & FAILED TO OBSERVE A PIPER ACFT ON ITS TAKEOFF ROLL. THE PLT IN THE PIPER ACFT, WHO WAS PREPARING TO DEPART, FAILED TO ANNOUNCE HIS INTENTIONS & POSITION ON THE TAXIWAY/RWY. FAILED TO OBSERVE THE INBND CESSNA & RENCE FAILED TO GIVE THAT ACFT THE RIGHT-OF-WAY AS REQUIRED. AS THE PIPER WAS BEING ROTATED FOR TAKEOFF THE CESSNA DESCENDED ONTO & COLLIDED WITH IT. THE PIPER PLT ABORTED HIS TAKEOFF, & CESSNA LANDED WITHOUT FURTHER MISHAP. BOTH PLTS REPORTED THAT THE PRESENCE OF TALL TREES LOCATED ADJACENT TO THE RWY'S APPROACH HAD OBSTRUCTED THEIR VISION.

- 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.
