I hope the FAA will use to address Part 27 shortcomings like:

An aircraft shall be flyable with the failure of one hydraulic system.

On one hydraulic system the aircraft will suffer no controlability issues during the edges of the flight envelope.

Should not burn to the ground after a survivable crash.

Fault tolerance: At pre-HAI presentations today data presented on the 427/429 showed the main transmission could last 4 HOURS after loss of the main Xmsn lube system. This was done at 30 minutes at min flying torque, max range torque, and then in increments of increasing torque every 30 minutes. Each range was chained in one run with each increment lasting 30 minutes. BEATS HELL OUT OF 12 MINUTES FOR THE PART 29 S-92.
