On 15 December 2010, an RAF CH-47 Chinook helicopter with serial number ZH891 was on a daytime tasking in flight within the Green Zone in Baghdad when it came under small arms and rocket-propelled grenade fire. A 7.62-mm round penetrated the cockpit and hit the instrument panel, severing 36 wires leading to it from various instruments. The wiring loom was sheared as a result, which caused an instruments failure without damaging vital components. As the Chinook was still able to fly level, pilot Flight Lieutenant Alex "Frenchie" Duncan decided to issue a pan-pan rather than a mayday to Bastion Tower. The Chinook made it back to Camp Bastion safely without further incident.
