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.

Pilot statement: this was a Diamond transition flight for the instrument rated private pilot. He has

Just transferred to our school and currently rents with us. This flight was in lieu of his desire to execute

An instrument flight in one of our archers due to icing in clouds above 2K feet that day. We decided to

Execute a dual flight for Diamond transition instead. The student was able to taxi, take off, cruise,

Navigate, communicate, and land under supervision. After landing I transferred control to myself and I

Executed the rollout, exit, contact, and taxi-back to 34 via b-a. I transferred control back to the student

At the hold short line 34. At about 11:15AM, holding short, I noticed smoke coming from under the right

Wing. Also rv N311VA reported a fire on my wheel. He was landing 34. I radioed to ATC that I was

Shutting down. They asked if I needed assistance. I asked them to send someone. Upon evacuation

We saw the fire in the right wheel-pant and moved away. I did call 911 once I observed the fire as I was

Not in contact with ATC anymore and I did not recall at that moment if I had been clear that there was

An urgent need for assistance. The flames moved up into the wing within about 3 minutes, then the

Trucks arrived. We were transported to the FBO and evaluated by emt's.

As I was on the controls I can attest that there was no excessive braking during the taxi, only normal taps to right and left to maintain directional control, and there was normal braking power available right up to stop at hold short line, even as the right wheel was on fire. This was the second flight immediately after delivery from its wing spar AD compliance in north carolina. I am not familiar with the procedures of dis- and re- assembly in the AD.

The cause of the fire is still undetermined. The manufacturer in cooperation with the NTSB will be disassembling the aircraft for return via truck and will perform an inspection at that time. Video indicates that the fire started on the right MLG and traveled upward to the lower side of the right wing.

As the FAA filed it

PILOT STATEMENT: THIS WAS A DIAMOND TRANSITION FLIGHT FOR THE INSTRUMENT RATED PRIVATE PILOT. HE HAS

JUST TRANSFERRED TO OUR SCHOOL AND CURRENTLY RENTS WITH US. THIS FLIGHT WAS IN LIEU OF HIS DESIRE TO EXECUTE

AN INSTRUMENT FLIGHT IN ONE OF OUR ARCHERS DUE TO ICING IN CLOUDS ABOVE 2K FEET THAT DAY. WE DECIDED TO

EXECUTE A DUAL FLIGHT FOR DIAMOND TRANSITION INSTEAD. THE STUDENT WAS ABLE TO TAXI, TAKE OFF, CRUISE,

NAVIGATE, COMMUNICATE, AND LAND UNDER SUPERVISION. AFTER LANDING I TRANSFERRED CONTROL TO MYSELF AND I

EXECUTED THE ROLLOUT, EXIT, CONTACT, AND TAXI-BACK TO 34 VIA B-A. I TRANSFERRED CONTROL BACK TO THE STUDENT

AT THE HOLD SHORT LINE 34. AT ABOUT 11:15AM, HOLDING SHORT, I NOTICED SMOKE COMING FROM UNDER THE RIGHT

WING. ALSO RV N311VA REPORTED A FIRE ON MY WHEEL. HE WAS LANDING 34. I RADIOED TO ATC THAT I WAS

SHUTTING DOWN. THEY ASKED IF I NEEDED ASSISTANCE. I ASKED THEM TO SEND SOMEONE. UPON EVACUATION

WE SAW THE FIRE IN THE RIGHT WHEEL-PANT AND MOVED AWAY. I DID CALL 911 ONCE I OBSERVED THE FIRE AS I WAS

NOT IN CONTACT WITH ATC ANYMORE AND I DID NOT RECALL AT THAT MOMENT IF I HAD BEEN CLEAR THAT THERE WAS

AN URGENT NEED FOR ASSISTANCE. THE FLAMES MOVED UP INTO THE WING WITHIN ABOUT 3 MINUTES, THEN THE

TRUCKS ARRIVED. WE WERE TRANSPORTED TO THE FBO AND EVALUATED BY EMT'S.

AS I WAS ON THE CONTROLS I CAN ATTEST THAT THERE WAS NO EXCESSIVE BRAKING DURING THE TAXI, ONLY NORMAL TAPS TO RIGHT AND LEFT TO MAINTAIN DIRECTIONAL CONTROL, AND THERE WAS NORMAL BRAKING POWER AVAILABLE RIGHT UP TO STOP AT HOLD SHORT LINE, EVEN AS THE RIGHT WHEEL WAS ON FIRE. THIS WAS THE SECOND FLIGHT IMMEDIATELY AFTER DELIVERY FROM ITS WING SPAR AD COMPLIANCE IN NORTH CAROLINA. I AM NOT FAMILIAR WITH THE PROCEDURES OF DIS- AND RE- ASSEMBLY IN THE AD.

THE CAUSE OF THE FIRE IS STILL UNDETERMINED. THE MANUFACTURER IN COOPERATION WITH THE NTSB WILL BE DISASSEMBLING THE AIRCRAFT FOR RETURN VIA TRUCK AND WILL PERFORM AN INSPECTION AT THAT TIME. VIDEO INDICATES THAT THE FIRE STARTED ON THE RIGHT MLG AND TRAVELED UPWARD TO THE LOWER SIDE OF THE RIGHT WING.
