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.

Asaa flt#131 departed ord for anc. There was no suspected tire damage on takeoff. When the gear was lowered on final at anc, the crew noted an unsafe indication on the right main landing gear, and suspected a microswitch malfunction. The crew recycled the gear, and received a safe indication for all three. The crew executed a normal landing, and noticed a increasing vibration at about fifty (50) knots. Suspecting a flat tire, the crew taxied off rwy 06L and stopped. The crew notified asaa operations and maintenance. Ops 1 (base ops vehicle) arrived before maintenance and said that the #4 tire was flat. Maintenance said the aircraft could taxi on the remaining tires. After taxiing about thirty (30) yards, the right MLG inboard tire blew. The passengers were deplaned, maintenance changed the right MLG tires, and towed the aircraft to the hangar. An inspection of the aircraft revealed damage to the flap, and several lines and brackets on right the gear. A review of the pilot's log book write up stated that the right landing gear indicated unlocked on first attempt, that they recycled the gear, and had a safe indication all around. The logbook also stated that when he had to cycle the gear a second time, the captain suspected tire damage.

As the FAA filed it

ASAA FLT#131 DEPARTED ORD FOR ANC. THERE WAS NO SUSPECTED TIRE DAMAGE ON TAKEOFF. WHEN THE GEAR WAS LOWERED ON FINAL AT ANC, THE CREW NOTED AN UNSAFE INDICATION ON THE RIGHT MAIN LANDING GEAR, AND SUSPECTED A MICROSWITCH MALFUNCTION. THE CREW RECYCLED THE GEAR, AND RECEIVED A SAFE INDICATION FOR ALL THREE. THE CREW EXECUTED A NORMAL LANDING, AND NOTICED A INCREASING VIBRATION AT ABOUT FIFTY (50) KNOTS. SUSPECTING A FLAT TIRE, THE CREW TAXIED OFF RWY 06L AND STOPPED. THE CREW NOTIFIED ASAA OPERATIONS AND MAINTENANCE. OPS 1 (BASE OPS VEHICLE) ARRIVED BEFORE MAINTENANCE AND SAID THAT THE #4 TIRE WAS FLAT. MAINTENANCE SAID THE AIRCRAFT COULD TAXI ON THE REMAINING TIRES. AFTER TAXIING ABOUT THIRTY (30) YARDS, THE RIGHT MLG INBOARD TIRE BLEW. THE PASSENGERS WERE DEPLANED, MAINTENANCE CHANGED THE RIGHT MLG TIRES, AND TOWED THE AIRCRAFT TO THE HANGAR. AN INSPECTION OF THE AIRCRAFT REVEALED DAMAGE TO THE FLAP, AND SEVERAL LINES AND BRACKETS ON RIGHT THE GEAR. A REVIEW OF THE PILOT'S LOG BOOK WRITE UP STATED THAT THE RIGHT LANDING GEAR INDICATED UNLOCKED ON FIRST ATTEMPT, THAT THEY RECYCLED THE GEAR, AND HAD A SAFE INDICATION ALL AROUND. THE LOGBOOK ALSO STATED THAT WHEN HE HAD TO CYCLE THE GEAR A SECOND TIME, THE CAPTAIN SUSPECTED TIRE DAMAGE.
