It's a terrible situation.

Eliminat ing any unbalanced prop contribution using the very nice piece of kit from S mart Avionics, the PB40 using dual two axis accelerometers (i also have his s martass in both my planes). Having used the dynavib in the past, i find the pb40 provides much more info , including spectrums, and the two accelerometers allows me to measure in al l axis=99, including torsional resonances. Still digesting the differe nces when the resonance kicks off. I did find that short-run ground balancing isn't good enough to get a consis tent result, and the dynamics in flight also appear to effect the results. S o fly with it i did.

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 dont 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. Its not 100% idiot proof... And not everyone is nimble enough to visually check, so we are back to square one again. 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 Ive offended anybody here, I simply come from the school of find the hole in the swiss cheese and do it right or just go home.
