NTSB narrative

THE CERTIFICATED AIRLINE PILOT/FLIGHT INSTRUCTOR, THE PILOT-IN-COMMAND, WAS DEMONSTRATING A SINGLE ENGINE LANDING TO A CERTIFICATED PRIVATE PILOT/DUAL INSTRUCTIONAL STUDENT. DURING THE LANDING ROLL, THE AIRPLANE BEGAN TO DRIFT TO THE RIGHT. THE PIC ATTEMPTED TO CORRECT THE DRIFT BY INCREASING THE RIGHT ENGINE POWER AND APPLYING LEFT RUDDER. THE AIRPLANE RIGHT WING BEGAN TO SETTLE TO THE GROUND AND THE PILOT SHUT DOWN BOTH ENGINES. THE AIRPLANE RECEIVED DAMAGE TO THE RIGHT GEAR FLAPS AND PROPELLER. AN INSPECTION REVEALED THAT THE RIGHT GEAR STRUT WAS BROKEN AT AN INSPECTION HOLE PROVIDED BY THE MANUFACTURER. THE GEAR STRUT WAS THE SUBJECT OF A MANUFACTURER'S SERVICE BULLETIN AND SUBSEQUENT FAA AIRWORTHINESS DIRECTIVE THAT REQUIRED AN INSPECTION FOR CRACKS. MAINTENANCE PERSONNEL HAD RECEIVED THE SERVICE BULLETIN BUT HAD NOT SCHEDULED AN INSPECTION.

Probable cause

A FATIGUE FAILURE OF THE LANDING GEAR STRUT DUE TO AN INADEQUATE DESIGN BY THE MANUFACTURER. CONTRIBUTING TO THE ACCIDENT WAS MAINTENANCE PERSONNEL NOT HAVING COMPLETED AN INSPECTION OF THE GEAR STRUT, IN ACCORDANCE WITH THE MANUFACTURER'S SERVICE BULLETIN.

  • 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.
  • API snapshot SHA-256: 9c5233f304b8ddcfd4d75af909e9ca2468220fde3f6b65d75a6e2efd259f478a; retrieved 2026-09-23T03:54:06.972Z.
