PMA approval and manufacturing standards of EXTEX Engineered Products / EXTEX

Operating from modern facilities in Gilbert, Arizona, EXTEX Engineered Products / EXTEX produces FAA-approved Parts Manufacturer Approval (PMA) components for commercial and military aircraft.

The regulatory approval framework confirms that every manufactured component complies with strict airworthiness standards, structural integrity criteria and material endurance benchmarks established by aviation authorities.

Integrating high-precision PMA replacement components from an experienced producer allows flight operators and helicopter fleet managers to reduce scheduled maintenance expenditures by up to forty percent while upholding superior flight safety margins.

Every manufactured part undergoes non-destructive evaluation and arrives with complete material compliance records.

Precision propulsion components for Pratt & Whitney Canada PT6 turboprop engines

The Pratt & Whitney Canada PT6 turboprop powerplant serves thousands of utility, passenger, and agricultural aircraft worldwide.

EXTEX manufactures more than ninety FAA-approved PMA line items designed for PT6 turboprop and turboshaft powerplants, supporting compressor rotors, planetary reduction gearbox assemblies, and high-temperature turbine sections across multiple variants.

Turbine airfoils engineered by EXTEX feature advanced anti-sulfidation protective barrier coatings that safeguard blade substrates against hot corrosion and oxidation during coastal or marine flight conditions.

Furthermore, airfoil part E3045741-01 holds an Alternative Method of Compliance (AMOC) rating, enabling direct installation on PT6 -114 and 114A engine variants.

High-durability compressor and gearbox assemblies for Rolls-Royce 250 powerplants

Rolls-Royce 250 (M250) turboshaft engines represent one of the most widely deployed rotorcraft powerplants, flying on Bell 206 JetRanger and MD 500 helicopters.

To deliver uninterrupted power delivery throughout demanding utility operations, EXTEX supplies precision compressor impeller wheels, turbine nozzle assemblies, and specialized reduction gearbox bearings.

Optimized gear tooth profiles combined with precision surface super-finishing enhance oil film formation, reduce running friction, and maintain balanced operating temperatures within the main gearbox housing.

These design enhancements mitigate micro-pitting fatigue wear and ensure reliable torque transfer to main rotor drive shafts during continuous flight cycles.

Main rotor hub assemblies and flight control components for Bell Helicopter fleets

Helicopter operators rely on dynamic components to complete search, rescue, law enforcement, and utility missions safely.

EXTEX delivers an extensive portfolio of flight-critical replacement components supporting over twenty-three Bell Helicopter models, including main rotor hub assemblies, dynamic mast components, and scissor-and-sleeve mechanisms for Bell 206, 407, 205, and UH-1 aircraft.

Precision swashplate assemblies engineered by EXTEX translate pilot cyclic and collective inputs into smooth blade pitch changes under high aerodynamic loads.

Machined from high-strength aerospace alloys, these dynamic rotor components resist cyclic fatigue stresses and undergo non-destructive inspection to prevent micro-fissure formation throughout demanding duty cycles.

Maintenance-free KAflex flexible drive shaft technology for rotorcraft drivelines

Conventional rotorcraft drive shaft universal joints necessitate frequent lubrication servicing and routine inspection for spline backlash.

The KAflex flexible driveline coupling system developed by EXTEX eliminates regular lubrication requirements entirely by utilizing laminated packs of high-strength spring steel diaphragms to transmit engine torque.

The dry diaphragm architecture accommodates angular and axial misalignment between the turbine powerplant and main rotor gearbox while damping high-frequency torsional vibration spikes.

This smooth driveline coupling protects reduction gears from resonance phenomena, lowers airframe vibration levels, and significantly reduces scheduled field maintenance overhead.
