An Azman Air Boeing 737-500, registration 5N-AIS performing flight ZQ-2316 from Lagos to Port Harcourt (Nigeria) with 114 passengers, was on final approach to Port Harcourt's runway 21 when the right hand engine (CFM56) emitted a loud bang and streaks of flames. The crew went around and landed safely later.
A passenger reported the right hand engine emitted a loud bang and streaks of flames, possibly as result of a bird strike, the aircraft tumbled rolling right and left, then the aircraft climbed out. The crew attempted two more approaches, but went around again and landed on the fourth approach about one hour after the first approach (editorial note: the Mode-S receiver lost contact with the aircraft during the first go around, thus we are unable to verify how many go arounds were done).
The airline reported there was unusual noise from the right hand engine, the crew initiated emergency procedures and brought the issue under control. The aircraft landed safely, all passengers disembarked unharmed. Reports circulating in Nigerian media (who provide the tail number as 5N-NAS which is unknown) about an engine explosion or loss of engine are false.
Nigeria's CAA opened an investigation into the occurrence reporting the aircraft suffered an engine issue but was able to land safely. A team of inspectors was dispatched on site to determine what led to the incident.
On Feb 4th 2019 Nigeria's AIB released their preliminary report reporting that departure and climb out of Lagos were uneventful, the captain ( 43, ATPL, 3,724 hours total, 92 hours on type, in words: ninety two hours) was pilot flying, the first officer (24, CPL, 629 hours total, 431 hours on type) was pilot monitoring. About 20-25 minutes into the flight, while the aircraft was enroute at FL290, the crew heard a bang and noticed a right yaw which lasted for about 5 seconds. When the crew looked up the engine parameters, all parameters were normal. The purser reported there was nothing abnormal noticed from the cabin except for the bang sound. The crew continued the flight normally.
On approach to Port Harcourt's runway 21, established on the localizer and glideslope runway 21 and after extending flaps 15 and lowering the gear, the crew disconnected the autopilot when the aircraft yawed severly to the right, severe vibrations were noticed and thrust asymmetry was determined. The left hand engine indicated about 3 to 3.5 units of vibrations and it's N1 was at 65%, the right hand engine indicated 35% N1 and the oil bypass filter light had illuminated. The crew decided to shut the right hand engine down.
The captain handed controls to the first officer in order to work the related procedures and to figure out what had happened. While executing the severe engine damage checklist, the approach became instable prompting a go around. The crew completed the checklists, were vectored onto another approach to runway 21 but came in high. The crew declared emergency and went around a second time. The aircraft landed safely on their third approach.
Nigeria's AIB released an immediate safety recommendation: "NCAA should ensure Azman Air Services Limited immediately takes further necessary steps to ensure that it review the training of the incident flight crew in order to be able to understand and recognise engine failure/malfunctions and its effect (s) at every phase of flight before they are allowed to resume flight duties."

Having spent 6 months working out of Lagos this isn't a surprise.
The country is a Corrupt, Lawless Failed State. To be fair it wasn't as bad as I was expecting.
Arik Air (who I was subcontracted to) was the most dysfunctional Airline I've ever seen.
The same mistakes every flight. A bush operation with jets.
I can only imagine how things must be with the smaller companies.
