Flydubai FZ1073 was diverted to Tabuk after a cockpit confrontation injured Captain Smit Machchhar and the co-pilot.
The Boeing 737 MAX 8 lost nearly 14,000 feet in less than 30 seconds before additional Flydubai pilots took control.
Israeli officials alleged the co-pilot stabbed Machchhar and tried to crash the aircraft, but the claims remain under investigation.
