He's better qualified than many CAA licensed L.A.M.E.s I know of. Most of them drive in external screws with a power screwdriver without a torque limit, leaving the power on until the pozi pattern inside the screw head gets stripped. My plane is covered in dents and scratches and none of these are from flying.
Of course the JAR145 maintenance organisation which they work for pays nice fees to the CAA so by definition its work must be excellent.
