Weather or not I have good English is not a matter for decision really. As for being open minded I'm glad to say I am. I'm willing to put up what I've done in aviation against what you have possibly done.
Next a letter from the CofA holder in case of an accident or incident, death or injury or anything else you can place up will not stand up
The court will see black and white. By meaely giving a letter to have signed by a maintenance org you have admitted that something is wrong. Defense would say my clients did not understand what was given to them. Then what as a lame are you going to say. Please hand me the soap !
