I hope you don't think I am nit picking here but to me Joe Public normal maintenance procedures means
1 Normal =an everday occurrence so you are saying its normal to fly 3900 miles to fix a fuel leak?
2.Maintenance= Carry out procedures to preserve from failure or decline not repair.So it is normal that ac out in theatre are sent back to the UK like XV231 and its normal to take up the cabin floors area.
Its normal for XV250 to have leaks so bad the ac has to be replaced in theatre .
If this is normal maintenance that god knows what state they have to be in for an unusual repair.
