NTSB narrative

AFTER CANCELING HIS IFR FLIGHT PLAN, THE PA-31 PILOT ENTERED THE TRAFFIC PATTERN FOR RWY 26 ON A CROSSWIND LEG. HE DID NOT SEE ANY TRAFFIC ON DOWNWIND AS HE ENTERED THE PATTERN. HE VISUALLY CLEARED THE AREA BELOW AND TO HIS RIGHT WHILE ON DOWNWIND AND AS HE LOOKED UP AND FORWARD HE SAW THE CESSNA 152 IN FRONT OF HIM. THE CESSNA WAS ALSO ON THE DOWNWIND LEG FOR RWY 26. THE PA-31 PILOT, UPON SEEING THE CESSNA, PULLED UP AND TO THE RIGHT, BUT THE LEFT LANDING GEAR AND UNDERSIDE OF HIS AIRCRAFT DESTROYED THE EMPENNAGE OF THE CESSNA WHICH SUBSEQUENTLY DESCENDED UNCONTROLLED TO GROUND IMPACT. THE PA-31 PILOT WAS ABLE TO LAND HIS AIRCRAFT, BUT THE LEFT GEAR COLLAPSED DURING THE LANDING ROLL.

  • 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.
