## Narrative

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

THE STUDENT PILOT WAS RETURNING TO MYF AFTER A FIRST SOLO CROSS COUNTRY FLIGHT. THE PILOT STATED THAT AFTER A NORMAL APPROACH AND LANDING TOUCHED DOWN ON THE MAIN GEAR FIRST AND AFTER A SHORT ROLL ON THE MAINS SET THE NOSE WHEEL DOWN AND THE PLANE STARTED VIOLENTLY SHAKING AND PULLING TO THE LEFT.

THE STUDENT PILOT STATED SHE HAD NEVER EXPERIENCED ANYTHING LIKE THIS. IN HER WRITTEN STATEMENT SHE ATTEMPTED TO CONTROL THE AIRPLANE WITH BACK ELEVATOR, RIGHT RUDDER AND APPLIED BRAKE PRESSURE IN ATTEMPT TO BRING THE AIRPLANE TO A STOP ON THE RUNWAY. ULTIMATELY, SHE WAS UNSUCCESSFUL AND THE AIRPLANE DEPARTED THE RUNWAY NEAR TAXIWAY H.

THE AIRCRAFT ^PRIVACY DATA OMITTED^ AND MECHANIC BOTH STATED THE NOSE WHEEL TIRE PRESSURE WAS LOW AND HAD USED AN INEXPENSIVE ^PRIVACY DATA OMITTED^ BRAND TIRE. THE MECHANIC STATED THAT HIS SHOP NO LONGER USES THE ^PRIVACY DATA OMITTED^ TIRES AS HE HAS FOUND THE TIRE CARCASS TO BE SOFTER THAN IN THE PAST. HE CONTINUED THAT THE SOFT TIRE WITH LOW PRESSURE WOULD HAVE CAUSED THE NOSEWHEEL SHIMMY. A NEW SHIMMY DAMPER WAS INSTALLED EARLIER THIS YEAR. I HAVE OBTAINED A COPY OF THE TIRE REPLACEMENT FROM THE AIRCRAFT MAINTENANCE RECORDS.
