Looks like VH-OXI. UH-1H

The information in that second link states that the aircraft is not fitted with a propellor.

The photo confirms that..... :eek:

Glad the pilot is OK.

Getting old now and eyesight going, but where the fcuk is the main rotor system ?

[gulliBell]

You can see the 48 ft diameter arc where a main rotor blade has hit the ground, after which the whole shooting match was ripped off the roof and exited the scene.

Has the T/R on the right so Bell 205A1. Beautiful machine, glad to see Pilot is okay.

[RVDT]

Has the T/R on the left so Bell 205A1.

Nope. UH-1H with the TR on the RH side. Dyncorp mod for UH1.

UH-1H and 205A were all on the LH side. A1 had 212 TR on the RH side.

This is definitely a UH-1H.

Ex OAS/Dyncorp converted UH-1H.

Airborne shot on the news last night, main rotor lying in the grass some distance forward of the aircraft.

What engine has this UH1H? I heard from an engineer Dyncorp put a PT6 in a few when he worked there.

The 205A1++ I spent this summer in was a HeliTrades STC had the t/r on the same side as this one, strakes, fast fin, -17 motor etc

Temsco is actually the STC holder for the - 67 PT6 engine installation in the H model Huey. They have done a huge amount of engineering over the years. I believe they started with the work DynCorp did and bought the STC and continued to refine the design. It is designed for the H model Huey and is installed along with the Helitrade STC ( i think that STC is now owned by Hillsborough Aviation) that puts the 212 main and tail rotor systems on the UH1-H, thus the right side tail rotor on the Huey. The 205A-1 could use the Helitrade STC and also be converted to what people call the 205A1+++. The +++ thing is an industry buzz word to describe the mods done to a 205A1, which is what the aircraft remains. The 205B came new with the 212 main rotor and 212 RH side tail rotor. We have no idea which variant the aircraft the subject of this thread actually is.

In the US the Helitrade STC for the 212 main rotor and tail rotor is not applicable to restricted category UH-1H aircraft. The only converted Hueys are the ones owned and operated by public agencies like Customs and Border Patrol and CAL FIRE ( and some other California fire agencies). Those aircraft, of course are not type certificated and can only be used by public operators. Im not sure how Temsco worked that into part of their engine conversion STC. Of course it might be a Bell 210 of which I think about 4 were built and two or 3 might still be flying but that is unlikley as I believe the only 210 operator is in the US. I suspect there are some pilots who think they've flown one variant but are misled by what someone calls it. The Huey family tree is not an easy one to follow.

Roscoe1,

Purely as a matter of interest how old might these helicopters be and how recent might the engine conversions be?

[Rigga]

Irrespective of age, the Huey Frames and Systems are tough, resilient and quite forgiving. All the transmissions and their support structures are also tough and forgiving, except when something the size of Earth gets in the way. try not to overthink this incident. It's not at all about the stresses found in this specialist operation.

After a bit more poking around it appears that Temsco may have sold the STC to a company called Trinity Aviation Group in British Columbia. As far as I know the Temsco prototype is the only one they built up and that was about 8 or 10 years ago. The Trinity web site is a bit strange as there is not much information on it and you can't find out too much about the company ( at least I haven't been able to). As with many older helicopter platforms, when aftermarket things have been getting made for years, there are many players involved. Some are well known and some are not. Some are producing and some are no longer. Stcs get bought and sold.
