IT CLIMBED TO ABOUT 200 FT AGL WHERE THE PLT MADE A 180 DEG TURN, FOLLOWED BY A 90 DEG TURN, FOLLOWED BY ANOTHER 180 DEG TURN. DURING THIS LAST TURN, THE ACFT WAS OBSERVED TO 'PORPOISE' OR FLUCTUATE IN ALTITUDE. THE M/R BLADE BEGAN TO 'FLAP' OR CONE ON THE 3RD 'PORPOISE.'

- 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.
