Excerpt from a letter sent by Adam Norwitch after a recent visit to the National Flight hangar for some airframe work – “I cannot thank you enough for all of your efforts in N112CZ. I know that I am as mechanically safe as possible because of all your tireless work during my one month stay. It is humbling to watch the effort and care that goes into heavy phase inspections. Thank you for being professional and honest.”
