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.

(-23) Aircraft left main tires caught fire following numerous high energy stops for maintenance purposes. The aircraft sustained minor damage, fire was contained to the tires and surrounding area. A company pilot and mechanic were onboard with no injuries reported. Prior to the incident, the aircraft underwent maintenance for "pulling to the left during landing". An inspection of the braking/antiskid system was accomplished and found satisfactory. Subsequent high speed taxiing was initiated to verify correct operation of the system. The Aurora (arr) tower manager, reported the aircraft completed three high speed taxi runs, when notified the crew to a fire on the left gear. A chronological report by the tower manager, indicates that three high speed taxis were accomplished between 2048Z and 2112Z (24 min). The pilot and mechanic both reported on two runs, each at 100 knot only one using tr's. the pilots account of the event, allows for approximately 40 minutes. Post fire inspection found both left main tire and wheel assemblies destroyed by fire. The lower wing skin surrounding the gear bay, left flap, main gear assembly and right hand wheels, all exhibited signs of heat damage (see attached)according to Aurora (arr) tower manager, the aircraft performed three high speed taxi's and was in the process of a 4th attempt when the tower notified the crew of a fire on the left main gear. A cronological report of the event, by the tower manager, indicates that three (3) high speed taxis were all accomplished between 2048Z and 2112Z (24 minutes). The pilot and mechanic reported that they performed two (2) runs, each at 100 KTS with only one tr application. The pilot's account allows for approximately 40 minutes. The weight of the aircraft at the time of the incident was 16,978 pounds. Post fire inspection found both left main tires and wheel assemblies destroyed. The lower wing skin surrounding the gear bay, left flap assembly and the main gear, displayed signs of heat damage. The right main wheels also exhibited signs of overheating. Inner bearing race of outboard left main wheel showed some signs of minor pitting. The following components will be sent to Bombardier for evaluation: fuse, control box, antiskid. See r & m aviation purchase order N40DK4209. The condition of the wing skin will be evaluated for heat damage by Bombardier engineering. This aircraft fitted with 390 degree f wheel fuse plugs and large brake assembly pn 5003096-7.

As the FAA filed it

AN INSPECTION OF THE BRAKING/ANTISKID SYSTEM WAS ACCOMPLISHED AND FOUND SATISFACTORY. SUBSEQUENT HIGH SPEED TAXIING WAS INITIATED TO VERIFY CORRECT OPERATION OF THE SYSTEM. THE AURORA (ARR) TOWER MANAGER, REPORTED THE AIRCRAFT COMPLETED THREE HIGH SPEED TAXI RUNS, WHEN NOTIFIED THE CREW TO A FIRE ON THE LEFT GEAR. A CHRONOLOGICAL REPORT BY THE TOWER MANAGER, INDICATES THAT THREE HIGH SPEED TAXIS WERE ACCOMPLISHED BETWEEN 2048Z AND 2112Z (24 MIN). THE PILOT AND MECHANIC BOTH REPORTED ON TWO RUNS, EACH AT 100 KNOT ONLY ONE USING TR'S. THE PILOTS ACCOUNT OF THE EVENT, ALLOWS FOR APPROXIMATELY 40 MINUTES. POST FIRE INSPECTION FOUND BOTH LEFT MAIN TIRE AND WHEEL ASSEMBLIES DESTROYED BY FIRE.
