Background
On 16 January 2017, flight MHV604, a Bombardier Challenger 60, departed from Male (VRMM) on a scheduled flight. The aircraft was cruising at FL250 when it experienced an engine failure and descended to FL230 without ATC clearance, coordinating with Mumbai (VABB) and Muscat (MCT) air traffic control.
Diversion Coordination
The flight originally intended to divert to OODQ, a small airfield in the Muscat area. MCT coordinated with OODQ, which confirmed it had no objection to accepting the flight but lacked refueling facilities. The aircraft reported that the engine had returned to normal operation and requested to divert directly to Muscat International Airport (OOMS) instead. MCT approved a direct route to OOMS.
Communication with ATC
At 09:57:50, MHV604 appeared on radar. At 10:10:29, radar identification was established. The crew reported 6 passengers and 3 crew on board, with 3 passengers injured. The injuries included cuts, bleeding, concussions, and possibly a broken arm or nose. The aircraft had 4 hours of fuel endurance and was operating on both engines.
Approach and Landing
Approach control provided radar vectors for an ILS approach to runway 08L. The aircraft was cleared for the approach and instructed to contact tower. MHV604 landed at 11:07 UTC on stand 10. Emergency services, including an ambulance, were requested and present upon arrival.
Medical Assistance
ATC coordinated medical information, relaying the nature of injuries—serious cuts, concussions, and possible broken bones—to medical staff on the ground. The crew confirmed that while the injuries were not life-threatening, they required priority handling.
