I think ge was in a B/C, so add about 5 - 10 kts to the posted A numbers -but one gets the idea.
Good flying, Mr Sledge - kudos and get well soon!!!

T-28B/C/D best glide speed [clean of course] 130 knots per PFM.
Engine stops at low level you'll land under the nose more or less. Big drag from prop.
re canned engines; my T-28D had one and has run perfectly. Issue with many canned failures was that not all of these engines were canned after overhaul etc but often just as "removed" - who knows why!

Does anyone have post crash photos of the airplane? I'm curious how much work it would take to rebuild it. I'm glad John is okay.
I put an engine on one of their T-28s several years ago. They were having substantial, repetative issues with the local round engine builder at the time. I hope that fella's work wasn't the source of this engine failure as well.

Link with a pic of the "downed" bird. Ouch, rebuildable with $$$$$. At least she didn't catch on fire.

How many hours on your canned engine when you pulled it from the can ?

Where's the speed brake on an A model? The whole thing? If its' got one your detailing crew has polished off yours Russ. Better hurry home before they polish the rockets off.

That's what I want to hear!
Hugh, next time you talk to him maybe you could ease it in that a buncha people he doesn't even know, nor who know him, are mighty happy to hear he's in one piece while feeling his pain.

the late A models had them, the early ones did not

I know of what you speak there, same problem here a couple of times. As much as they fly thier T-28s I betcha it wasn't one of "his" engines as it probably would have been over the 100 hour mark by now.

my "canned" engine came from Vietnam and was "0" TSO...it was a Pensacola overhaul according to the paperwork if my memory serves me correctly.
ran like a swiss wrist thingie...
we did a thorough inspection and carefully pre-oiled with hot oil etc before running after installation.

I'll try to talk to John later today to get more info. At present about all I can add is that he went in clean, touched down about 115-120 kts. He was going to lower some flaps, decided to go under the power lines, was afraid that flaps might balloon him into the lines so stayed clean.
The engine had just undergone oil change and plug change. The Trojan Phlyers have a couple of guys to do their routine maint. but send the engines to someplace in Ark. for MOH. They do use an oil analysis kit.
He really has a nasty gash on his scalp(like the old Frankenstein movies).
I'll pass on you guys's regards.

The overhaul guy in Arkansas typically builds a pretty good engine. I'm glad to know John is in such high spirits. Definitely pass along the well wishes from me, please.

Tailspin,
I just had dinner with John and the rest of the Trojan Phlyers just a few weeks ago in Denton, Tx.
Please pass on our best wishes for a speedy recovery to John. He is a good friend of ours.
