The Australian Transport Safety Bureau recommends that the Civil
Aviation Safety Authority alert operators of aircraft equipped with
turbo-charged engines to the potential risks of engine damage
associated with detonation, and encourage the adoption of
conservative fuel mixture leaning practices.
CASA also accepts Recommednation R20000250 and has published an
article in the January/February aviation safety magazine Flight
Safety Australia. Furthermore, CASA is considering further action
on this matter and is consulting the aeroplane and engine
manufacturers with a view to them improving their engine leaning
procedures.
