Issues I have with this modification;
1. Call me annal, drilling holes into and through the fuselage skin establishes a stress point that may not but could lead to something worse than a door departing the aircraft; this possibility has not been adequately addressed yet.

2. I don’t believe this modification sufficiently negates the possibility of the inexperienced from still, somehow, getting the door misaligned and locked at the same time. Although it is a good attempt and may very well work, lets hope all the time, it still lends itself to operational failure. It’s not 100% idiot proof... And not everyone is nimble enough to visually check, so we are back to square one again.

3. Can somebody please explain how they came to the conclusion that its a higher safety priority to try and “prevent” the action of door latch security rather than “ensure” the action of door latch security, because i’m left feeling like i’ve missed something here...

Best Failsafe Solution Possible - fit two series wired switches to the end of each shoot bolt pin, per door, activating a, 100% the door is secured for take off, visual indication lamp on the instrument panel; Left Door Secured / Right Door Secured ——- Done

Sorry if I’ve offended anybody here, its not my intention, I simply come from the school of “let’s try and break the design”; find the hole in the swiss cheese and “do it right or just go home”.
