The only thing that would be looming is in the AAIB Special Bulletin : S1-2016, namely that in a air display in 2014 in another type of aircraft, at another venue, the pilot of G-BXFI was stopped by the FDD following concerns about the execution of a manoeuvre. A CAA FSO was present but did not witness the occurrence. After an informal discussion with the pilot the same day, the CAA took no further action and did not formally record the incident.
The AAIB goes on to say, nevertheless the occurrence could have provided an opportunity to explore the pilot`s continued competence.
