Interesting, here's a key phrase:
"Rotorcraft certificated prior to Amendment 29-24 can update their certification basis to take advantage of this provision."
I imagine therefore that Bell won't be the only company to take advantage of this as FAR ammendments are generally accepted at face value by other certification authorities. No one willing to moan that Sikorsky or MD are also taking advantage of this, or can MD not play because they don't have tail rotors? This can only be good news for companies as they get increased capacity because they know that pilots are always able to land with the wind on the nose, right?
