Narrative:
A CRJ-200ER, registered JA206J, operated by J-Air, took off from Oita Airport as the scheduled flight JL2362 and landed on runway 32R at Osaka International Airport. While the aircraft was taxiing on the taxiway after landing, a caution message was displayed for a right engine fire detection system failure, and subsequently a warning message was displayed for a right engine fire. While the crew responded to the engine fire warning message, the aircraft continued to taxi and entered the parking spot.
During maintenance work after the flight, evidence of fire was found within the engine fire zone.

Probable Causes:
It is highly probable that the cause of this serious incident was that the coupling nut connecting the right engine fuel manifold (fuel supply piping) and fuel injector (fuel injection nozzle) No. 14 was loose, fuel leaked from this area and was ignited by the heat of the engine, which resulted in fire in the designated fire zone.
Although it is somewhat likely that the reason why the coupling nut was loose was the insufficient tightening force of the coupling nut, resulting in gradually loosening caused by factors such as engine vibration, the Japan Transport Safety Board couldn’t determine the cause of the loosening.
