Airwolf Aerospace is now offering FAA-approved PMA (parts manufacturer approval) main rotor head elastomeric bearings for the Bell 407. “This is Airwolf’s first elastomeric offering,” said Eric Wolff, Airwolf Aerospace v-p of sales and business development. The new bearings are available for immediate delivery, the company said.

The new PMA'd bearings “are equivalent to Bell part numbers 407-310-100-107, 407-310-101-105, and 407-310-102-103,” according to Airwolf, and include dampers, shear bearings, and lead-lag (CF) bearings.

Airwolf’s PMA’d helicopter TT straps have been available for more than 11 years, and the company manufactures these for the Bell 206, 204, 205, 212, and UH-1, and Enstrom models. 

“As the aerospace industry continues to consolidate, independent small businesses such as Airwolf are crucial to operators as they fight to keep costs under control,” Wolff said. “Airwolf is always striving to give helicopter operators more choices and reducing their costs.”
