Overview

• The AAIB report, published in July 2025, concluded that inappropriate control inputs by the right-seat passenger triggered the crash during final approach.
• The Grob 109B hit trees and came down on a busy road outside Aston Down airfield after the misapplied controls caused an abrupt pitch-down.
• Wind gusts of 15–20 knots created turbulence that investigators say may have contributed to the passenger’s “action slip.”
• Both occupants were injured, with the passenger suffering severe spinal trauma that required several days in hospital.
• The findings echo a June 2024 British Airways incident and could prompt regulators to review right-seat control configurations and training protocols.
