From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry 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.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

On October 27, 1998, at 1328 hours mountain standard time, a Beech C90, N37PT, ran off the runway and collided with an electrical utility box during takeoff at Sedona, Arizona. The aircraft sustained substantial damage; however, neither the flight instructor nor his student were injured. The aircraft was operated by hayden leasing lc as an instructional flight, and was originating from the Sedona Airport when the accident occurred. Visual meteorological conditions prevailed at the time and no flight plan was filed. After striking the utility box, the right main gear separated from the aircraft. The pilot continued the takeoff from Sedona, and later landed at prescott, Arizona, where the aircraft ground looped off the right side of the runway during the landing roll. (-23) see narrative #LAX99LA018 (.4) the certificated flight instructor (CFI) and student pilot departed on a local training flight. During the takeoff roll, the airplane began drifting to the right. The CFI applied full left rudder and left aileron but was unable to stop the drift. After the CFI rotated, he heard the gear warning horn. After becoming airborne, he was advised by another airplane that his right gear was not visible. He was also advised by an FBO operator that his right gear was missing. Concerned that he might also have a fuel leak, the CFI declared an emergency and landed. An inspection of the runway revealed a tire track which left the right side of the runway 1,050 feet from the approach end and continued into the grass to an electrical service box on the right side of the runway. Cracks and gouges were found on the cement electrical service box and the right main gear assembly was found on the ground beyond it. The fractured portion of the upper torque link revealed characteristics consistent with an overstress separation. The CFI and ground witnesses said weather was not a factor.

As the FAA filed it

ON OCTOBER 27, 1998, AT 1328 HOURS MOUNTAIN STANDARD TIME, A BEECH C90, N37PT, RAN OFF THE RUNWAY AND COLLIDED WITH AN ELECTRICAL UTILITY BOX DURING TAKEOFF AT SEDONA, ARIZONA. THE AIRCRAFT SUSTAINED SUBSTANTIAL DAMAGE; HOWEVER, NEITHER THE FLIGHT INSTRUCTOR NOR HIS STUDENT WERE INJURED. THE AIRCRAFT WAS OPERATED BY HAYDEN LEASING LC AS AN INSTRUCTIONAL FLIGHT, AND WAS ORIGINATING FROM THE SEDONA AIRPORT WHEN THE ACCIDENT OCCURRED. VISUAL METEOROLOGICAL CONDITIONS PREVAILED AT THE TIME AND NO FLIGHT PLAN WAS FILED. AFTER STRIKING THE UTILITY BOX, THE RIGHT MAIN GEAR SEPARATED FROM THE AIRCRAFT. THE PILOT CONTINUED THE TAKEOFF FROM SEDONA, AND LATER LANDED AT PRESCOTT, ARIZONA, WHERE THE AIRCRAFT GROUND LOOPED OFF THE RIGHT SIDE OF THE RUNWAY DURING THE LANDING ROLL. (-23) SEE NARRATIVE #LAX99LA018 (.4) THE CERTIFICATED FLIGHT INSTRUCTOR (CFI) AND STUDENT PILOT DEPARTED ON A LOCAL TRAINING FLIGHT. DURING THE TAKEOFF ROLL, THE AIRPLANE BEGAN DRIFTING TO THE RIGHT. THE CFI APPLIED FULL LEFT RUDDER AND LEFT AILERON BUT WAS UNABLE TO STOP THE DRIFT. AFTER THE CFI ROTATED, HE HEARD THE GEAR WARNING HORN. AFTER BECOMING AIRBORNE, HE WAS ADVISED BY ANOTHER AIRPLANE THAT HIS RIGHT GEAR WAS NOT VISIBLE. HE WAS ALSO ADVISED BY AN FBO OPERATOR THAT HIS RIGHT GEAR WAS MISSING. CONCERNED THAT HE MIGHT ALSO HAVE A FUEL LEAK, THE CFI DECLARED AN EMERGENCY AND LANDED. AN INSPECTION OF THE RUNWAY REVEALED A TIRE TRACK WHICH LEFT THE RIGHT SIDE OF THE RUNWAY 1,050 FEET FROM THE APPROACH END AND CONTINUED INTO THE GRASS TO AN ELECTRICAL SERVICE BOX ON THE RIGHT SIDE OF THE RUNWAY. CRACKS AND GOUGES WERE FOUND ON THE CEMENT ELECTRICAL SERVICE BOX AND THE RIGHT MAIN GEAR ASSEMBLY WAS FOUND ON THE GROUND BEYOND IT. THE FRACTURED PORTION OF THE UPPER TORQUE LINK REVEALED CHARACTERISTICS CONSISTENT WITH AN OVERSTRESS SEPARATION. THE CFI AND GROUND WITNESSES SAID WEATHER WAS NOT A FACTOR.
