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 September 4, 2011, aircraft N316PA was performing touch and goes with instructor pilot privacy data omitted and student pilot privacy data omitted. During the third landing on runway 7R, the instructor pilot noticed the aircraft was nose low and decided to perform a full stop. The instructor took control of the aircraft and rolled out to taxiway C6 where he exited the runway. The instructor pilot stated that he believed the aircraft had blown a nose landing gear strut and was safe to taxi. As the instructor pilot powered up to taxi back to parking, he heard the left and right propellers strike the ground. The aircraft's nose landing gear drag link failed at the knuckle where the airframe mounted portion of the draglink connects to the landing gear portion. The airframe side of the draglink had material failure at the attachment bolt hole. The nose landing gear moved forward (opposite of the direction of retraction) and came to rest on the foward nose cone bulkhead. As the pilot was attempting to steer the aircraft with the rudder pedals, the added stress caused the steering horn mount bolts to fail. The additional loss of support for the nose landing gear and added power caused the gear to crush and crack the nose cone bulkhead. This caused the aircraft to settle further and allowed the propellers to strike the ground

As the FAA filed it

ON SEPTEMBER 4, 2011, AIRCRAFT N316PA WAS PERFORMING TOUCH AND GOES WITH INSTRUCTOR PILOT ^PRIVACY DATA OMITTED^ AND STUDENT PILOT ^PRIVACY DATA OMITTED^. DURING THE THIRD LANDING ON RUNWAY 7R, THE INSTRUCTOR PILOT NOTICED THE AIRCRAFT WAS NOSE LOW AND DECIDED TO PERFORM A FULL STOP. THE INSTRUCTOR TOOK CONTROL OF THE AIRCRAFT AND ROLLED OUT TO TAXIWAY C6 WHERE HE EXITED THE RUNWAY. THE INSTRUCTOR PILOT STATED THAT HE BELIEVED THE AIRCRAFT HAD BLOWN A NOSE LANDING GEAR STRUT AND WAS SAFE TO TAXI. AS THE INSTRUCTOR PILOT POWERED UP TO TAXI BACK TO PARKING, HE HEARD THE LEFT AND RIGHT PROPELLERS STRIKE THE GROUND. THE AIRCRAFT'S NOSE LANDING GEAR DRAG LINK FAILED AT THE KNUCKLE WHERE THE AIRFRAME MOUNTED PORTION OF THE DRAGLINK CONNECTS TO THE LANDING GEAR PORTION. THE AIRFRAME SIDE OF THE DRAGLINK HAD MATERIAL FAILURE AT THE ATTACHMENT BOLT HOLE. THE NOSE LANDING GEAR MOVED FORWARD (OPPOSITE OF THE DIRECTION OF RETRACTION) AND CAME TO REST ON THE FOWARD NOSE CONE BULKHEAD. AS THE PILOT WAS ATTEMPTING TO STEER THE AIRCRAFT WITH THE RUDDER PEDALS, THE ADDED STRESS CAUSED THE STEERING HORN MOUNT BOLTS TO FAIL. THE ADDITIONAL LOSS OF SUPPORT FOR THE NOSE LANDING GEAR AND ADDED POWER CAUSED THE GEAR TO CRUSH AND CRACK THE NOSE CONE BULKHEAD. THIS CAUSED THE AIRCRAFT TO SETTLE FURTHER AND ALLOWED THE PROPELLERS TO STRIKE THE GROUND
