## Narrative

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

NARRATIVE: ON WEDNESDAY, JULY 16, 1997, AT APPROXIMATELY 1620 PDT, CFI NICKLAS TURESSON AND STUDENT PILOT LILIT GRIGORIAN DEPARTED MONTGOMERY FIELD (MYF), SAN DIEGO, CA IN N6273R, A CESSNA MODEL 172RG, FOR A FAR PART 141 TRAINING FLIGHT. THE FLIGHT WAS TO ANOTHER LOCAL AIRPORT, BROWN FIELD (SDM), TO CONDUCT LANDING AND TAKE OFF/TOUCH AND GO, OPERATIONS. WHILE AT SDM, TURESSON WAS NOTIFIED VIA RADIO FROM ANOTHER AIRCRAFT THAT DURING HIS LAST TOUCH AND GO, THE NOSE WHEEL ASSEMBLY HAD FALLEN OFF N6273R. TURESSON DECIDED TO RETURN TO MYF TO CONDUCT THE EMERGENCY LANDING. AT APPROXIMATELY 1909 PDT, TURESSON MADE A SUCCESSFUL LANDING AT MYF. THE AIRCRAFT SUSTAINED MINOR DAMAGE. NEITHER TURESSON NOR GRIGORIAN WERE INJURED; NO FIRE RESULTED. INVESTIGATION DETERMINED THAT THE NOSE WHEEL ASSEMBLY AXLE BOLT, AN5-47, HAD FAILED IN THE THREADED AREA. INSPECTION OF THE BOLT INDICATED THAT A PRE-EXISTING FRACTURE OF THE BOLT HAD OCCURRED, TIME UNKNOWN. A REVIEW OF THE MAINTENANCE RECORDS INDICATED THAT ON 6/6/97, N6273R EXPERIENCED A HARD LANDING. INSPECTION OF THE AIRCRAFT DID NOT FIND ANY DAMAGE TO THE NOSE WHEEL/LANDING GEAR ASSEMBLY. NOTE: A VISUAL INSPECTION OF THIS BOLT WOULD NOT HAVE DETERMINED THAT THE BOLT WAS CRACKED. THE CFI INDICATED THAT THE LANDINGS EXPERIENCED ON THIS FLIGHT WERE NOT EXCEEDINGLY HARD. THE CESNA 172RG IS THE AIRCRAFT UTILIZED FOR PRIMARY TRAINING FOR ALL OF THE SCHOOL'S STUDENTS. THE OPERATOR HAS INITIATED AN ADDED MAINTENANCE ITEM THAT WILL REPLACE THE NLG AXLE BOLT EVERY TIME THE NLG TIRE IS REPLACED. THIS INCIDENT DID NOT INVOLVE A NMAC OR A PILOT DEVIATION. FAA FORM 8010-4, MALFUNCTION OR DEFECT REPORT WILL BE FILED.

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.
