c/n 1235, built 01/67 as U-10D s/n 66-14333 for USAF accepted 01/67, t/n “66-14333”, USAF Assistant Air Attache aircraft in Savannakhet, Laos in the late 1960's maintained by the 606^th Special Operations Squadron at Nakhon Phanom, Thailand, released from storage Davis-Montham AZ 12/69, US Army ? '?, Sacramento Air Material Area, McClellan AFB CA 08/70, storage Davis-Montham AZ 11/74, declared excess released from storage 02/75, as N87731 transferred by Aid Excess Property Division, New Cumberland Army Depot, New Cumberland, PA 04/75, to the Summer Institute of Linguistics NC (Jaars 34^th Helio of 46) installed 1400 series dorsal fin and trapazoidal rear windows 1700 series cargo door Jaars cargo pod & aerodynamic enhancement speed mod (STC SA00788AT) install 4 Cessna seats cargo door convert military 120 gal LR fuel system to civilian configuration 02/78, ''named Friendship of Tulsa'' dereg crated for export as PK-UCB Universitas Cenderawasih, Jayapura, Irian Jaya, YAJASI (Jaars), accident on takeoff slid off runway brake locked @ unknown area 08/86, incident cargo door came open in flight @ unknown area 4/00, removed from service high time reg cancelled 10/11, YAJASI (Jaars) disassembled Sentani, Indonesia and presently stored in a 30’ sea land container waiting for export authorization to US.

Interestingly the 'Cargo' door that folds to the rear was developed by the Factory for the 7/800 series Helios with trigear, probably because the under surface of the wing is so high that the utility/litter door that lifts out and up would be a problem. It was installed on all 7/800s as standard equipment and was offered as optional equipment on older Helios.
Jaars also offers an STC to install this door on older Helios but, I just dont understand why you would need an STC to install a factory option, a log book endorsment should be enough.

Another thing is that with the 'Utility' door that lifts up and out, coming open in flight is a nonevent, it just floats up and it gets really windy, the door that opens to the rear is definetly an incident when it comes open in flight as it did on this a/c.

Would you know the logic behind converting the 4 tanks to 4 valves ( military ) to transfer pumps ? ( Civil )  What is the danger of the military configuration ?  Transfering and loosing fuel when parked non level ?  A lot of civil planes can do that.  May be there is some regulation on the FAR that check for imbalance after parking ?

I believe the rational for using the transfer system was primarily for standardization. Flying multiple airplanes of the same type with multiple pilots it's generally safer to have them configured the same when possible. Plus, the 1200 series military U10D/H295's would have had the overhead valves, which we didn't like as much as the transfer fuel system. Jim Metzler

Found a picture of c/n 1235 as PK-UCB while located in Danau Bira Indonesia in'83, at Stevens Helio Facebook page. It was posted by a Jaars member.

Note earlier paint scheme posted it as #1 in the picture queue above.

Facebook makes it difficult if you aren't signed up they only allow you to see half the page they block the other half with a facebook application that you can't make go away.

I see that Facebook, Google and Twitter now have one third of the people in the world signed up. The head honchos of those 3 corporations now have more influence in the world than the prime ministers or presidents of most midsize or smaller countries, why do people worry about Russia influencing much of anything.
