NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

THE AIR TAXI PILOT WAS LANDING THE TRICYCLE GEAR AIRPLANE ON A HARD SURFACED RUNWAY. HE SAID THE TOUCHDOWN WAS ON THE MAIN LANDING GEAR, AND WAS SMOOTH AND UNEVENTFUL UNTIL HE LOWERED THE NOSEWHEEL TO THE RUNWAY. ALSO, HE SAID THAT AS SOON AS THE NOSEWHEEL TOUCHED DOWN, THE AIRPLANE VEERED TO THE LEFT, AND THAT HE WAS UNABLE TO TURN THE AIRPLANE TO THE RIGHT. THE AIRPLANE CONTINUED TO THE LEFT, AND THE NOSEWHEEL STRUT SUBSEQUENTLY COLLAPSED, DAMAGING THE FIREWALL. THE PILOT SAID THE AIRPLANE HAD AN OVERSIZED NOSEWHEEL TIRE. AN FAA INSPECTOR, WHO WAS FAMILIAR WITH THE AIRPLANE, SAID THE NOSEWHEEL STRUT MAY HAVE BEEN OVERINFLATED, WHICH MAY HAVE CONTRIBUTED TO STEERING DIFFICULTIES. THE OPERATOR, WHO SUBMITTED THE NTSB ACCIDENT REPORT FORM, INDICATED THAT THERE WERE NO PREACCIDENT MECHANICAL PROBLEMS WITH THE AIRPLANE.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

THE PILOT'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL. A FACTOR RELATING TO THE ACCIDENT WAS: THE DIMINISHED NOSEWHEEL STEERING CAPABILITY DUE TO AN OVERINFLATED NOSEWHEEL STRUT.
