Synopsis

Air carrier B737-800 flight crew reported engine vibrations during final at 300 ft. AGL and rising temperatures after landing/taxi.

Narrative

A few moments after the 500 foot call on approach to Runway XX we felt a moderate vibration and then as the pilot flying a significant yaw to the right. I saw the N1 on the number 2 engine decrease significantly. I believe this was around 300-400 feet AGL. I then instinctively concentrated on just landing the aircraft safely and deal with the engine issue on the ground. After landing; we did not receive any fire indication so I taxied off to a safe area where we called for CFR (Crash Fire Rescue). As we were taxiing off on the high speed I noticed the EGT (Exhaust Gas Temperature) on the number 2 engine rising significantly and going bright red and can't really recall but maybe I saw EGTs over 1100 degrees. I instinctively pulled the cutoff on the number 2 engine. CFR was great and was there very quickly; they noticed quite a bit of smoke from the tail cone is what I believe I heard. They followed us in and told us we smoked pretty bad as we pulled into the gate as well.Cause: Taking an aircraft that had been in maintenance for 10 days that wasn't properly repaired. The aircraft was apparently on oil watch as well. This aircraft should not have been put back in service.

Second reporter narrative

We were established on a stable approach to visual Runway XX backed up by the ILS. As pilot monitoring (PM) I had made the 500 foot call of stable target sink. At roughly 300-400 feet I felt a vibration and something seemed off. Captain said 'we've lost our engine.' Captain did a great job of aviating the aircraft to a safe approach and landing. On landing roll out I advised Tower to 'roll the trucks on Runway XX; we had a right engine failure at about 500 hundred feet .' We cleared the runway and noticed the EGT (Exhaust Gas Temperature) on engine number 2 was rising rapidly over 1000 degrees. At Captains command we cutoff the engine. Thankfully there was no fire indication and Captain spoke with the flight attendants (FAs) and made a PA. The response time by ZZZ Airport Rescue and Firefighting (ARFF) was very impressive. Captain requested a designated ARFF frequency to better communicate with the response crew. After getting the all clear from them we taxied into the gate with ARFF escort.Cause: The aircraft had not flown for 10 days prior to our flight. The captain had briefed and discussed a right valve fix on the number 2 engine before leaving ZZZ1. We did not know that it was on an oil program until advised by maintenance personal after the event.It would be nice to know the cause of the engine failure if a cause is ever determined.
