## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of control - on ground/water, landing - roll
  - directional control - not maintained, pilot in command (cause)
  - maintenance,inspection - improper, other maintenance personnel (contributing factor)
  - ground loop/swerve - inadvertent, pilot in command

## Analysis

THE ACFT WAS ON LANDING ROLL WHEN IT BEGAN TO VEER FROM THE RWY. THE PLT ATTEMPTED TO MAINTAIN DIRECTIONAL CONTROL BUT THE ACFT LEFT THE RWY AND COLLIDED WITH A TAXIWAY MARKER SIGN CAUSING SUBSTANTIAL DAMAGE TO THE ACFT. SHORTLY THEREAFTER, THE RIGHT MAIN LANDING GEAR COLLAPSED. THE LANDING GEAR TORQUE LINK SHOWED A FRACTURED SURFACE TYPICAL OF FATIGUE PROGRESSION. THERE WAS EVIDENCE OF IMPROPER INSPECTION PROCEDURED USED THAT FAILED TO DISCLOSE THE FATIGUE AND CRACKED SURFACE IN THE TORQUE LINK.
