Deadly AW139 Crash Following Foggy Night Takeoff | The Why Spotlight #5
Fatal AW139 Crash in Night Fog: Understanding the Human Factors Behind the Tragedy
Flying at night already presents unique challenges, but when dense fog is added to the mix, even experienced pilots can find themselves in dangerously unfamiliar territory. In this spotlight, we examine a tragic accident involving an AgustaWestland AW139 helicopter in the U.K., where two pilots lost their lives due to a combination of visibility limitations and operational decisions. As an EASA student pilot or aspiring aviation professional, understanding these real-world incidents is crucial for building safer flying habits.
Let’s explore what happened, why it happened, and what you—as a future pilot—can learn from it.
What Happened: AW139 Crash Overview
Two pilots, operating an AW139 helicopter, were scheduled to depart from a private site en route to Coventry, UK. The flight was to take place at night, in poor weather conditions marked by thick fog.
– Type: Helicopter – AgustaWestland AW139
– Scenario: Nighttime vertical departure from a private location
– Conditions: Low visibility due to heavy fog
– Outcome: Loss of control shortly after takeoff, resulting in the complete destruction of the aircraft and fatalities of both crew members
Investigators determined that the pilots attempted a vertical climb immediately after takeoff—an already complex maneuver made even riskier under the night’s zero-visibility fog conditions.
The Dangers of Vertical Departures in IMC
Vertical departures are inherently challenging. Unlike forward takeoffs, vertical climbs eliminate external references early in the departure phase. In instrument meteorological conditions (IMC), the lack of visual cues can rapidly lead to spatial disorientation.
Key risks involved in vertical departure during IMC include:
– Immediate reliance on instruments
– Increased workload and potential task saturation
– Loss of situational awareness in spatially disorienting environments
– Reduced margin for error during early climb-out
Human Factors: The Real Cause Behind the Tragedy
This accident wasn’t just about weather—it was about human decision-making.
Even though both pilots were experienced, the decision to proceed with a vertical departure in zero visibility conditions set up a high-risk scenario. The human factors at play likely included:
– Pressing ahead despite marginal weather (get-there-itis)
– Overconfidence in pilot ability and aircraft capability
– Underestimating the difficulty of the maneuver in poor visibility
– Poor crew resource management (CRM) under stress
Training Tip: Never underestimate the risks associated with degraded visual environments (DVE), especially at low altitude during critical flight phases like departure and landing.
Lessons Learned for EASA Student Pilots
This tragic event underscores several critical lessons that every pilot in EASA training should understand:
1. Maintain situational awareness—especially during night ops
2. Use conservative decision-making in poor weather conditions
3. Always have an alternate plan if visibility deteriorates
4. Understand and respect the limitations of both crew and aircraft
5. Practice strong CRM techniques to manage workload and risk
Being current and competent with instrument flying is essential, but even more crucial is knowing when not to fly or when to modify your departure strategy to better suit the conditions.
Stay Safe, Stay Smart
Mental discipline, risk assessment, and communication between pilots are just as important as technical flight skills. Learn from real-life investigations like this one to continuously sharpen your decision-making and deepen your understanding of how to handle high-pressure situations.
