// Rotor-Wing Components
Helicopter components for Airbus and MDHI platforms — engineered by rotorcraft specialists
Rotor-wing aircraft demand a higher standard of component engineering. The dynamic loads, vibration environments, and mission criticality of helicopter parts leave no margin for compromise. PT Aerospace was founded by engineers who have spent careers testing the limits of critical helicopter components — and building better ones.
Our rotor-wing catalog spans Airbus and MDHI platforms, with particular depth in drivetrain and structural components. Our signature innovation — machined aluminum upgrades replacing OEM cast magnesium — delivers measurable durability improvements for operators across both platforms.
