The pilot said he experienced an unsolicited rollback in engine power prior to the collision. Reportedly, some power was regained however, but not in time to avoid the collision. But, the jump chairman reported that no change in the engine’s operation was observed throughout the mishap. Witnesses at the takeoff area reported that the winds were 12 knots out of the Northeast, which would have given the flight a quartering tailwind component for the takeoff. According to the Flight Manual, the maximum demonstrated crosswind is 12 knots. An examination of the airplane failed to indicate any system malfunction or failure @ Mobile AL 9/90, Mike Mullins TX sold wreck '90, to Patrick Taylor for use in restoring stallion proto no. 2, incident damaged by saltwater immersion by Hurricane Katrina @ near New Orleans Covington LA '05, dbr sold '07 sold as scrap to be used for display purposes only Last Plane Out llc (David Grantham) LA, '09 sold to Airborne Leasing llc LA, donated to tech school Baton Rouge LA

Anyone know the name of the tech school and the current condition of this A/C.

As always any further information or pictures would be greatly appreciated.

The stab is the same width or  longer ?

The stab is the same width or  wider ?

Tail span on H-391 through H-295 is 13' 4''

Book says tail span on Twin and Stallion and twin 18'.

The book says 15' on H-800 tail span  ? Edit: This appears to be correct

Book also says 1^o dihedral on all helios. Is this correct.

[Louis]

The book says 15' on H-800 tail span ? I think this is wrong ?

I don't know if it is wrong or right, but my 800 should had been equipped with a larger stab.  I had the same one as 391-295, and it did fly strange when lightly loaded. This big 8 cylinder engine far forward should had been compensate with a bigger stab

added magazine article

In article they refer to N9991F c/n 004 that was used for flight testing but the pictures are of N9992F c/n 006 both were returned to USA by Reed, Schachle & Turinsky of  AK along with c/n 007 as N1384X.

The picture of Stallion that crashed in Cambodia is c/n 015.

Hey Doug, not sure about the others, but the stab width on H-4 is 15' and 1/2".

[Doug Johnson]

To me it sounds like H-14, Has the wrong stabilator on it the book says 15' and you can prove it.

Makes me wonder if their are any other H-800s out there with the wrong stabilator.

Where would you find the correct one. You would probably have to dissasemble a 15 foot stabilator
to get all the measurements, spar thickness etc. to make one.

Probably almost as cheap to convert to H-295.

Received 3 pictures from Wayne Dickson of Stallion 006 while it was at Laramont Aviation

Open above as 4^th, 5^th and 6^th pictures above.

Wonder if one H-800 have the right 15 stab.  This measurement haunt me since 20 years.  Sometimes, protocol change.  Like the way to measure the empty weight.  Some years with the oil and unusable fuel, the with the oil and unusable fuel.  Giving a strong augmentation in empty weight like for some Cessna 180.  Giving the impression that earlier model where quite lighter ( they are, but not by so much )

I wonder if the 800 stab, given at 15 feet, but never seen, would be a difference on how you calculate it, like with or without the wingtip of the stab.

I came across the fuselage of 006 a couple months ago as well as one other Stallion fuselage (I was unable to see the data plate on that one), plus a container of parts. They were sitting in a field at a grass strip here in Washington. It sounds like it has been sold already, but thankfully it will be in good hands.

[Doug Johnson]

I suspect that the other stallion is c/n 2 N70850 go here in the site

https://flyhelio.com/smf/index.php?topic=1205.msg4669;topicseen#msg4669

both c/n 2 and c/n 006 were at a Tech school Baton Rouge LA, probably tracked
down by Larry Tuefel to use as parts to keep Stallion c/n 001 flying.

Or maybe to put together another Stallion wouldn't that be cool

[StaticThrust]

I wouldn't be surprised if the other fuselage was N10039. It was unpainted with no landing gear and all the windows were broken out. However from what I could tell, it didn't appear to have any major corrosion like it was exposed to salt water.
