Good questions! I know the engines are scoped on major checks but not on daily or weekly checks. This would need to change whilst this cloud is affecting airspace. I have no doubt we would need to carry out a range of checks on the engines and pitot static systems post flight as long as the aircraft are operating in the area of the ash cloud.
Again these are procedures I hope someone is working on now. I believe the BA aircraft will have been subjected to a wide range of inspections as it is no coincidence the aircraft flew to Cardiff, as this is a heavy maintenance base for BA.
I suspect the authorities have had a full report from BA but I doubt BA will publish this to the public other than making vague statements for very obvious liability reasons.
