Re: Confessions Of A C-2 Greyhound COD Pilot

T-56s have been around forever and were a well-proven design when the E-2 was built. I suspect it’s rather typical Navy support and maintenance. The AF is the same way to a lesser degree. Guys that joined the Reserves from fighters were astounded by the unreliability and poor parts support for airli...

Re: FAA Regs Part 23 vs Part 25

You can build a single-engine Part 23; but no such plane under Part 25. A Part 23 twin-engine plane, under 6,000#, essentially must only be controllable, no specified engine-out performance. A normal category Part 23 plane must have structure capable of 3.8G while a Part 25 G design standard is 2.5G...

You’d have to find a pretty big, i.e. expensive turboprop to make this a single. Plus two engine redundancy.

I wonder if this isn’t tightly drawn to FDX requirements and not flexible enough for many operators—no pressurization, fixed gear.

Are you talking about rotor bow? That’s not cooling strictly; it’s because of the heat rising into the top of the cowl and causing differential heat on the core and the rotor to “bow”. It is solved by dry motoring the engine during start to equalize temps and unbow the rotor shaft.
