If it was that dangerous to fly a Robinson without the fuel bladder tanks how come that all those H269s or Enstroms etc just get along without fuel bladder tanks? Can't those tanks just burst upon impact as well?
Shouldn't we go ahead and change the certification requirements for helicopters in general (fuel bladder tanks only, please)?
Maybe that's why the authorities hesitated that long before they turned the SB in an AD?
Just a thought?
