A CAP 10B aerobatic aircraft (G-BXBU) crashed near Buckland St Mary, south of Taunton, Somerset, killing both occupants.
G-BXBU departed Watchford Farm in Somerset, which was the aircraft’s home base, at 08:04 hrs local time with the pilot and one passenger on board. Their intention was to fly to St Mary’s on the Isles of Scilly for a day trip before returning to Watchford Farm later that afternoon. At the time of departure, the local weather was described by witnesses as clear skies with good visibility.
The pilot found himself stuck above cloud during a cross-country flight under Visual Flight Rules. After contacting the Distress & Diversion Cell for assistance he was transferred to the radar frequency of a nearby airport, at which the cloud base was below the minimum required for the approach offered. The pilot, who was not qualified to fly in cloud, lost control of the aircraft during the subsequent descent and the aircraft was destroyed when it hit a tree. Both occupants were fatally injured.
=AAIB Conclusion=
The aircraft collided with terrain because the weather conditions deteriorated beyond the capabilities of the pilot who was not trained or qualified to operate in poor weather. The forecasts available when the pilot assessed the weather did not accurately reflect the extent of the poor weather.
=Safety Recommendation 2023-011=
It is recommended that the Civil Aviation Authority publish guidance for general aviation pilots on responding to unexpected weather deterioration, highlighting the factors affecting their performance and the benefits of planning before the flight how they will respond.
=Safety Recommendation 2023-012=
It is recommended that the Civil Aviation Authority require air traffic controllers to receive training regarding the human performance characteristics and limitations associated with stress. This should include the verbal cues that may indicate that a pilot is operating under high stress, and mitigation strategies to help controllers deal with such events.
=Safety Recommendation 2023-013=
It is recommended that the Civil Aviation Authority specify the types of information that air traffic controllers will obtain and record when responding to aircraft in an emergency to ensure that pilots’ needs are met and reported correctly if communicated to other air traffic control units.
=Safety Recommendation 2023-014=
It is recommended that the Civil Aviation Authority encourage the use of checklists in air traffic management operations when dealing with abnormal and emergency situations.
=Safety Recommendation 2023-015=
It is recommended that the Civil Aviation Authority determine the effect the D&D Cell’s executive control has on civil ATCOs and inform civil ATCOs of any differences in their responsibilities whilst executive control is exercised.
=Damage Sustained to Airframe=
Per the above AAIB Report "aircraft destroyed". The CAA agreed with this conclusion, and the aircraft was de-registered (with the registration G-BXBU cancelled) with effect from 1-3-2022 as "aircraft destroyed" and the registered owner "deceased"
Contemporary press reports (see link #11) named the two fatalities as Jonathon ("Joe") Mann, aged 69 (pilot) and "His passenger in the fatal collision was artist Margaret Costa, 74, of East Devon".
