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) Pilot was executing a normal takeoff. Approaching v-rotation speed (approx. 120-125 knots) pilot says he heard a loud crack like a rifle shot then a loud boom. Aircraft tired to swerve left and pilot realized the right engine was no longer running. Pilot was able to keep aircraft under control and stop aircraft by the end of runway. Upon stopping, he cleaned up the right engine by turning fuel and generator off then requested to taxi to the ramp. Pilot taxied aircraft to Nashville jet center where he shut number two engine down. My visual inspection of the number one engine revealed complete failure of all visible compressor discs. The guide vanes were all broken from the back with the exception of one which had visible damage on the front. The vane with damage to the front was situated at the 5 o'clock position as you are looking into the engine inlet. The majority of the failed blade and disk debris was thrown back out the front of the engine and was resting in the inlet. There were some minor metal particles on the tail pipe which had come through the engine. Given the amount of damage to the engine, it is not possible for me to determine what caused the failure. privacy data omittedprivacy data omitted

As the FAA filed it

(-23) PILOT WAS EXECUTING A NORMAL TAKEOFF. APPROACHING V-ROTATION SPEED (APPROX. 120-125 KNOTS) PILOT SAYS HE HEARD A LOUD CRACK LIKE A RIFLE SHOT THEN A LOUD BOOM. AIRCRAFT TIRED TO SWERVE LEFT AND PILOT REALIZED THE RIGHT ENGINE WAS NO LONGER RUNNING. PILOT WAS ABLE TO KEEP AIRCRAFT UNDER CONTROL AND STOP AIRCRAFT BY THE END OF RUNWAY. UPON STOPPING, HE CLEANED UP THE RIGHT ENGINE BY TURNING FUEL AND GENERATOR OFF THEN REQUESTED TO TAXI TO THE RAMP. PILOT TAXIED AIRCRAFT TO NASHVILLE JET CENTER WHERE HE SHUT NUMBER TWO ENGINE DOWN. MY VISUAL INSPECTION OF THE NUMBER ONE ENGINE REVEALED COMPLETE FAILURE OF ALL VISIBLE COMPRESSOR DISCS. THE GUIDE VANES WERE ALL BROKEN FROM THE BACK WITH THE EXCEPTION OF ONE WHICH HAD VISIBLE DAMAGE ON THE FRONT. THE VANE WITH DAMAGE TO THE FRONT WAS SITUATED AT THE 5 O'CLOCK POSITION AS YOU ARE LOOKING INTO THE ENGINE INLET. THE MAJORITY OF THE FAILED BLADE AND DISK DEBRIS WAS THROWN BACK OUT THE FRONT OF THE ENGINE AND WAS RESTING IN THE INLET.
