A UPS Boeing 767-300, registration N342UP performing freight flight 5X-357 from Managua (Nicaragua) to Miami,FL (USA), was on final approach to Miami's runway 08L descending through 200 feet AGL when tower instructed the crew to go around and turn left by 10 degrees. The crew initiated the go around, turned left and overflew a Citation busines jet, waiting in position for departure, at 475 feet. The B763 landed safely about 15 minutes later.

On Jun 2nd 2017 (!) the NTSB released their preliminary notice reporting the B763 was descending through 200 feet AGL when the ASDE-X system alerted the tower controller of the conflict with the business jet, who was still waiting in position. The controller instructed the B763 to go around and turn 10 degrees to the left, the B763 overflew the business jet at 475 feet. Visual meteorological conditions prevailed at the time. The occurrence was rated an incident and is being investigated by the NTSB.

On Apr 14th 2020 the NTSB reported the local controller instructed the business jet holding short at taxiway K1 (at the runway threshold) to line up runway 08L and wait, the controller did not issue a takeoff clearance immediately to allow for proper separation with another departure that had taken off runway 08R. The controller had been using runways 09 and 12 for arrivals, however, cargo aircraft preferred runway 08L for shorter taxi times to the cargo apron. No arrivals to 08L or 08R had occurred for considerable time, when 5X-357 reported on frequency and was cleared to land on runway 08L after the business jet had been instructed to line up and wait. The controller did not tell 5X-357 that traffic was holding in position on runway 08L. The controller became distracted by an aircraft misunderstanding a hold short instruction as well as another aircraft reporting foreign objects on a taxiway and later reported, he missed the developing conflict until ASDE-X issued the alarm. At that point the Boing 767 was at 200 feet AGL and was instructed to go around and turn left 10 degrees. The 767 subsequently overflew the business jet by 475 feet. The controller was relieved from duty and filed a mandatory occurrence report.

On Apr 15th 2020 the NTSB released their final report concluding the probable cause of the incident were:

The controller's issuance of a landing clearance to an arriving aircraft while another aircraft was in position on the same runway. Contributing to the incident was the controller's non-compliance with traffic advisory procedures, and insufficient requirements for use of memory aids to track arrival and departure operations.
