Introduction
On 12 August 2016, a Cessna 750 Citation X, registration G-CEDK, experienced a smoke event while taxiing at Inverness Airport, Scotland. The aircraft, powered by two Rolls-Royce AE 3007C1 turbofan engines, was on a private flight with two crew and three passengers on board. No injuries were reported, and no damage to the aircraft occurred.
Incident Description
Shortly after starting the left engine, the flight crew noticed a transient smell of burning rubber, which they described as identical to tyre smoke from a landing aircraft. No visible indications of anything abnormal were observed, and the smell subsequently disappeared. The aircraft was taxied for departure with the crew monitoring for any recurrence. Just after completing the turn onto Runway 11, the commander noticed a small amount of pale grey smoke below the level of the instrument coaming, which was confirmed by the co-pilot.
Evacuation
The aircraft was brought to a halt, and the crew reviewed the situation before deciding to carry out the Emergency Evacuation Drill. Air Traffic Control was informed, and an evacuation was carried out through the aircraft main door. Passengers were led upwind of the aircraft as the Airport Fire Service arrived.
Post-Incident Inspection
A post-incident inspection by the operator's maintenance engineer identified that the cabin air cycle machine had failed, causing smoke to enter the cabin.
