Worked with a guy (Brit) several years ago who to be honest was useless I questioned his qualifications with my boss several times only to be told all was okay, He moved onto another company and was tasked to go to ZUR or GEV to inspect a tail strike on a B747-200F he signed it of as within AMM limits the A/C returned to MUC where it was inspected by the Feds he was then checked out as the damage was way beyond limits, subsequently busted but no prosecution (WTF???) last I heard He was running a pub in Kent for those of you who have an idea who I am talking about his initials are GH top bloke but a fraudster with no technical training never the less and I was glad he was caught.
