Need to put it into context , its a MECHANICS certificate , not an engineers licence. Totally different system to ours . I have both and used A&P on 747 's ,we did the work and any decisions , i.e MEL release involved a phone call to MCC where the equivalent to our LAE made the decision and let you release it. Took a bit of getting used to when you were turning a couple around and one was N reg and the other not !!!! Had to remember to make the phone call !!!
