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 April 29, 2022, the rochester flight standards district office received an occurrence (event id 714941) for experimental amateur built Glasair Sportsman N11316. It was reported that the aircraft experienced a hard landing and a nose gear collapse in Jamestown, NY (jhw) after a flight from niagara falls (iag). Damage to the aircraft was limited to the prop, engine, cowl, nose gear, nose gear support structure and the engine firewall. A review of the photographs supplied by the airport manager indicated that the remainder of the aircraft structure appeared undamaged. After inspection by local maintenance, it was determined that the axle nut was missing and that the axle had shifted, jamming and locking up the nose wheel. The tire subsequently blew and the wheel dug into the runway, causing the nose gear leg to fold under the aircraft and allowing the nose and prop to strike the runway. NTSB investigator privacy data omitted was advised and forwarded the photos to engineering. Engineering deemed the damage was not substantial, and the NTSB did not investigate. There were two glasair service bulletins addressing the nose gear axle nut, sb 61 and sb 160. Both service bulletins advised changing the nose wheel axle nut from a shear nut to a tension nut. The pilot advised that he had installed the recommended tension nut at the time the aircraft was built, and that the same nut was installed during the condition inspection when the nose wheel bearings were repacked. privacy data omitted At glasair was contacted and asked if there had been any further issues with the nose wheel axle nut coming off and allowing the axle to shift and jam the nose wheel. His response was that there had been no further incidences since the service bulletins had been published. Because the nut in question was missing, it is impossible to determine what nut had been installed at the last inspection. As a result of this incident and the questions arising from the missing nut as well as issues with the maintenance log book entries provided to the FAA, airman counseling is be given to the privacy data omittedrepairman.

As the FAA filed it

ON APRIL 29, 2022, THE ROCHESTER FLIGHT STANDARDS DISTRICT OFFICE RECEIVED AN OCCURRENCE (EVENT ID 714941) FOR EXPERIMENTAL AMATEUR BUILT GLASAIR SPORTSMAN N11316. IT WAS REPORTED THAT THE AIRCRAFT EXPERIENCED A HARD LANDING AND A NOSE GEAR COLLAPSE IN JAMESTOWN, NY (JHW) AFTER A FLIGHT FROM NIAGARA FALLS (IAG). DAMAGE TO THE AIRCRAFT WAS LIMITED TO THE PROP, ENGINE, COWL, NOSE GEAR, NOSE GEAR SUPPORT STRUCTURE AND THE ENGINE FIREWALL. A REVIEW OF THE PHOTOGRAPHS SUPPLIED BY THE AIRPORT MANAGER INDICATED THAT THE REMAINDER OF THE AIRCRAFT STRUCTURE APPEARED UNDAMAGED. AFTER INSPECTION BY LOCAL MAINTENANCE, IT WAS DETERMINED THAT THE AXLE NUT WAS MISSING AND THAT THE AXLE HAD SHIFTED, JAMMING AND LOCKING UP THE NOSE WHEEL. THE TIRE SUBSEQUENTLY BLEW AND THE WHEEL DUG INTO THE RUNWAY, CAUSING THE NOSE GEAR LEG TO FOLD UNDER THE AIRCRAFT AND ALLOWING THE NOSE AND PROP TO STRIKE THE RUNWAY. NTSB INVESTIGATOR ^PRIVACY DATA OMITTED^ WAS ADVISED AND FORWARDED THE PHOTOS TO ENGINEERING. ENGINEERING DEEMED THE DAMAGE WAS NOT SUBSTANTIAL, AND THE NTSB DID NOT INVESTIGATE. THERE WERE TWO GLASAIR SERVICE BULLETINS ADDRESSING THE NOSE GEAR AXLE NUT, SB 61 AND SB 160. BOTH SERVICE BULLETINS ADVISED CHANGING THE NOSE WHEEL AXLE NUT FROM A SHEAR NUT TO A TENSION NUT. THE PILOT ADVISED THAT HE HAD INSTALLED THE RECOMMENDED TENSION NUT AT THE TIME THE AIRCRAFT WAS BUILT, AND THAT THE SAME NUT WAS INSTALLED DURING THE CONDITION INSPECTION WHEN THE NOSE WHEEL BEARINGS WERE REPACKED. ^PRIVACY DATA OMITTED^ AT GLASAIR WAS CONTACTED AND ASKED IF THERE HAD BEEN ANY FURTHER ISSUES WITH THE NOSE WHEEL AXLE NUT COMING OFF AND ALLOWING THE AXLE TO SHIFT AND JAM THE NOSE WHEEL. HIS RESPONSE WAS THAT THERE HAD BEEN NO FURTHER INCIDENCES SINCE THE SERVICE BULLETINS HAD BEEN PUBLISHED. BECAUSE THE NUT IN QUESTION WAS MISSING, IT IS IMPOSSIBLE TO DETERMINE WHAT NUT HAD BEEN INSTALLED AT THE LAST INSPECTION. AS A RESULT OF THIS INCIDENT AND THE QUESTIONS ARISING FROM THE MISSING NUT AS WELL AS ISSUES WITH THE MAINTENANCE LOG BOOK ENTRIES PROVIDED TO THE FAA, AIRMAN COUNSELING IS BE GIVEN TO THE ^PRIVACY DATA OMITTED^REPAIRMAN.
