Introduction to the Islay Aircraft Incident

On the 29th of June, 1994, an aircraft incident on the Scottish island of Islay drew significant attention due to the involvement of a high-profile individual, King Charles III, who was then Prince Charles. This event involved a British Aerospace 146-100 jet, operated by the Royal Air Force and designated under RAF tail number ZE700. This aircraft was part of the 32 Squadron, famously known as ‘The Royal Squadron,’ tasked with transporting members of the UK royal family. The incident occurred under complex circumstances that involved both human error and adverse weather conditions.

Background and Events Leading to the Incident

The aircraft departed from Aberdeen, carrying Prince Charles to Islay for scheduled local engagements. Prince Charles, an experienced pilot with a UK Pilots’ Licence, took the role of the pilot flying. The co-pilot was Squadron Leader Graham Laurie, a highly experienced officer. Despite their expertise, the landing attempt at Islay Airport was fraught with challenges. The airport features a primary tarmac runway 13/31, which, while capable of accommodating jet aircraft, spans only 1,545 meters in length.

On approach, the aircraft encountered overcast conditions with gusty winds. The chosen runway had a tailwind component, which is less than ideal for landing. It was reported that the aircraft’s approach was unstable and too fast, with the speed at threshold notably exceeding the recommended speed by 32 knots. This excessive speed contributed to a delayed touchdown, which occurred well down the runway, leaving insufficient distance for a safe stop.

Detailed Analysis of the Landing Attempt

The aircraft’s high approach speed and the tailwind led to it touching down with only about half of the runway length remaining for deceleration. Investigations later revealed that the main landing gear (MLG) did not make contact promptly due to the aircraft ‘wheelbarrowing’ on the nose landing gear, delaying critical deceleration processes like the deployment of lift spoilers and the initiation of ground idle engine power. Furthermore, premature application of the MLG brakes, before the activation of the anti-skid system, caused the tires to lock and subsequently fail.

This combination of factors resulted in the aircraft overrunning the runway and coming to a halt in a ditch, causing substantial damage to the aircraft. Thankfully, there were no physical injuries to the passengers or crew. The incident led to an extensive RAF Board of Inquiry, which concluded that both the pilot (Prince Charles) and the co-pilot were negligent. Prince Charles was found to have failed to control the aircraft’s speed and descent path adequately, while Squadron Leader Laurie failed to provide timely advice regarding the tailwind and the aircraft’s approach parameters.

Subsequent Impact and Retirement of ZE700

Following the incident, the aircraft underwent repairs costing over £1 million, highlighting the financial impact of the accident. The RAF’s ZE700 returned to service and continued its duties until its retirement in 2022. It now resides at the South Wales Aviation Museum, serving as a historical exhibit. This incident marked a pivotal moment in Prince Charles’s flying career, prompting him to relinquish his pilot’s license and cease flying the following year, in 1995.

Conclusion

The 1994 Islay aircraft incident is a compelling case study of how even experienced pilots can face challenges under adverse conditions. It underscores the importance of adhering to flight operation protocols, especially concerning approach speeds and landing configurations. This event not only had immediate safety implications but also influenced royal aviation protocols and the personal decisions of those involved, most notably, the future King Charles III.
