The VHA OH-58 Main Rotor Blade is a direct composite replacement for the OEM metal blades on OH-58A+ and C models. Featuring a highly efficient NASA-developed airfoil, and an advanced carbon/epoxy construction, this blade delivers increased service life, reduced operating costs, and improved durability - all without hub modification.

Eligible for Public Use via Certificate of Conformity (CoC), with STC approval as a future VHA goal.
