Helimark, I am not sure why the frame on the 600 cracks, just as I am not sure why the tailboom attach fittings on the AS350 series aircraft crack (AD 2001-04-14), and I never said that the MD600 was the finest example of american engineering ever built. I would perfer a 369F anyday.
I am just pointing out that the Border Patrol do make the aircraft work. Lets agree to disagree on this. I do wish you and all your colleagues many safe hours flying the AS350s, but just remember, if your "down in the dirt" you'll probably miss the luxury of NOTAR.
