NTSB narrative

The airline transport certificated pilot was conducting a visual flight rules (VFR) scheduled domestic passenger flight. The airplane was in cruise flight at 2,500 feet msl, at an airspeed of about 200 knots. The pilot said he caught a glimpse of a sea gull that suddenly dove toward the water. The sea gull struck the right wing, outboard of the right engine nacelle. The pilot landed the airplane without any problems. The right wing's leading edge upper surface received downward and aft crushing of the wing structure about 18 inches across, and about 8 inches deep. The damage to the wing included several ribs, forward spar, leading edge skin, and the deice boot.

  • 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: local date, investigation status. Values present in the bulk record are kept.
  • The date is the local date; the NTSB stores the UTC date 1999-10-16.
  • API snapshot SHA-256: d6d6f3f503a82d041f7b621032236a4260575f9fe66e8d4f8cb19c45576b131d; retrieved 2026-09-18T16:51:56.670Z.
