Russian To American Part Detective Work!

Thu Apr 04, 2013 11:13 pm


I have a unique situation I'm trying to find a solution for. I am new to the industry completely and a relative greenhorn. But I have a fun project I'm working on that requires some detective work and the right connections.

My employer has a customer who is having a Russian aircraft (small utility double prop) produced under a BASA bilateral agreement here in the states. We are replacing many of the parts for "better" American made parts that we prefer in the aircraft.

1 of which are the flap actuators. Here comes the hitch. We have the specs for the Russian actuator mechanism, but that gets you relatively nowhere when it comes to finding a supplier for an American flaps actuator. If you talk with sales, they dont know that information, and if you talk with someone who knows there parts and has a relative idea of specs they are difficult to get a hold of. On top of this, the current loads (rated and max) on the russian part are a good deal higher then many related american flaps actuators that go in similar sized aircraft (ie cessna, beechcraft). If I could sit down with a catalogue of all the flaps actuators made in the states it would be easy...lengthy, but easy. Too bad, its relatively impossible to get one of those...

Also, we really need a part that is already on a working American craft - makes it much easier with the FAA to get that part certified on our aircraft. (can be a helicopter linear actuator, as long as it fits the specs)

I have specs, I have pics.

I've made some great connections already in trying to find the part, but I figure it couldn't hurt to throw it out there to a community that may enjoy something such as this.

Anyone have an idea as to who would be keen to reach out to in regards to this?

Thanks for any suggestions,

Type of aircraft? Actuator type, length and stroke?
Would love to help, but need information first...

Its a small utility aircraft. But the specs for the part we are replacing are most like those of one found on a VLJ.
At this point we are trying to find a part that is as close as possible to these specs, but made in the US. There are plenty of actuator manufacturers that could make this part, but finding an aerospace company that has one in stock has been difficult. We are not trying to RD a new part. Too expensive, and the customer would rather keep the old part then dish out 300k.

This is an electro-mechanical linear actuator. Must be programmable to 3 intermittent positions.
Rated: 550.8 lb-force
Max: 826 lb-force
Max Static: 2203 lb-force

DC Supply Voltage:
Rated: 28V
Operating Voltage: 24 to 29V

Operating Stroke of Rod:
Greater then or equal to 180mm (7.086 inches)

Total dimensions of current part (retracted) = 82x107x363 mm or 3.23x4.2x14.3 inches

let me know if there is other information that may help.
