ILS27LEFT, v interesting tks for posting.
Piper.Classique, It's a final backup; a quick walkround to see that nothing is hanging off, that a tyre doesn't look 'a bit odd' nor does anything else, there are no obvious dents, it just looks normal.
One I will never forget is departing Frankfurt when a young ground engineer noticed a shadow on a windmilling fan and climbed into the cowl and stopped the rotation. Three or four blades were damaged by tyre debris from a previous burst and this had not been noticed. Regrettably, whilst the damage was just within limits, the vibration levels were not and, because the whole thing was now recorded, I had to refuse the aircraft. IMO it was OK to fly but because it was just outside limits it was a no no.
