I see you have met my son. If hell had a handle on it, that boy would break it. Actually, its the spring inside the latch that broke. Without it, duct tape appears to be the only way to keep the door shut. I will acknowledge that it probably just wore out, but it was on his watch, and I have to make him feel bad about something.
To make matters worse, the plane and my son are in Louisiana where he is staying with my parents due to difficulty in finding an instructor in Atlanta. So in the end, it will probably be my dad who fixes it and me that pays the bill.
