In 1982, our maintainers came up with a great wheeze for stopping SHAR engine wear from windmilling engines on deck (inflatable blanks would blow out in the wind). They gently inserted a broom handle through the LP fan, which locked it very effectively. This was annotated in the F700 with an entry stating “Broom handle inserted to stop engine rotation” and was cleared with another one stating “Broom handle removed”, before flight.
On one occasion, I went to sign an aircraft out and found the following entry; “Intake inspected - no broom handle found. Uckers pieces removed from underneath cold nozzles”.

Not only brilliant maintainers, also a great sense of humour!
