## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

DURING A NORMAL ROLL-OUT AFTER LANDING, ON HAF RUNWAT 12, THE RIGHT MAIN GERA COLLAPSED. THE TWO RIGHT PYLON TUBES FAILED BELOW THE WELD, CAUSING THE AIRCRAFT TO DRAG THE RIGHT WING AND VEER RIGHT.  ONE LEFT TUBE ALSO FAILED, HOWEVER THERE WAS NO PROP STRIKE, AND AIRCRAFT DAMAGE REMAINED MINOR.  SUBSEQUENT INSPECTION OF THE FAILED PYLONS REVEALED THAT THE BLUEPRINT REQUIRED A 7/8"X0.49" TUBE, BUT A 7/8"X0.35" TUBE HAD BEEN INSTALLED AT THE TIME OF MANUFACTURE, AND SOLD TO THE AIRCRAFT BUILDER AS AN ASSEMBLY. A PREVIOUS LANDING GEAR FAILURE INCIDENT HAD WEAKENED THE STRUCTURAL INTEGRITY OF THIS AERA, AND PRECIPITATED PREMAUTRE FAILURE OF THE FRAME STRUCTURE.  THE FAILED PYLON TUBE EVIDENCED A PRIOR STRIKE MARK, IN ADDITION TO THE STRIKE MARK GENERATED DURING THIS INCIDENT.  ALTHOUGH THE PREVIOUS GEAR FAILURE HAD BEEN REPAIRED, IT HAD BEEN RE-INFORCED BEYOND THE MANUFACTUER'S DRAWINGS, EVENTUALLY TRANSFERRING THE LOAD TO AN ALREADY WEAKENED AREA, NOW EVIDENCED AS ALSO BEING INFERIOR FROM THE TIME OF PRODUCTION.  A SAFETY RECOMMENDATION WILL BE PURSUED SEPARATELY.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
