FREE SHIPPING IN CONTINENTAL US

Let’s make 2024 the year that Yak 52 aluminum bellcranks disappear for good.

Since 2017 we have supplied these BD121 Steel Elevator Bellcranks exclusively to a few trusted Yak maintenance shops on the East and West Coast US.

Today, we can stand behind our product with more than 25 units in the field.

If you didn’t check it during the prebuy, now would be a great time to take a magnet to your Yak 52’s elevator bellcrank and make sure this important Russian AD has been complied with.

This is part of the airframe’s primary control structure - and is not a job for the casual hobbyist - talk with the A&P IA who does your Yak 52’s conditional before undertaking this project.

Applies to Yak 52 and TW only ( Yak 50, 55 and CJ’s are unaffected by this AD)

Bellcrank supplied primed with zinc phosphate plus SKF roller bearing. A translation of the BD121 repair instructions is included.

Optional precision drilling jig available at additional cost
