The initial inspection is carried out by an engineer.
The repetitive visual inspection is carried out by a rated pilot.
If it fails that inspection then an engineer is required to carry out the tap test.
I suggest that everyone should read the AD on the FAA's web site before signing anything.
The pilot certification called for in the AD is probably not valid in the UK, but a statement quoting the AD number and the sub paragraphs probably is.
I am sure EASA will clarify the situation!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!
