Industry-Leading PMA Coverage

Aero-Classics offers the largest number of FAA-PMA approved oil coolers in the world, providing unmatched application coverage across the Lycoming engine range. This extensive certification portfolio ensures availability of approved replacement oil coolers for virtually all Lycoming-powered aircraft, from vintage classics to modern certificated aircraft.

The comprehensive PMA approval coverage eliminates the challenges of sourcing obsolete or hard-to-find OEM oil coolers, providing cost-effective alternatives with full FAA approval and airworthiness documentation. This extensive range supports aircraft maintainers in keeping vintage and modern aircraft operational with readily available, certified cooling components.

Revolutionary Aluminum Oil Coolers

Aero-Classics manufactures the only FAA-PMA approved all-aluminum oil coolers for PA-18 and PA-22 aircraft, representing a significant advancement in cooling technology for these classic Piper models. These innovative aluminum coolers deliver multiple performance advantages over traditional steel construction.

The all-aluminum design achieves half the weight of original steel coolers while providing 20% more cooling efficiency. This weight reduction improves aircraft performance and useful load capacity, while the enhanced cooling efficiency provides better engine temperature management and increased operational margins. The aluminum construction also offers superior corrosion resistance for extended service life.

Precision CNC Machined Base

Aero-Classics Continental oil coolers feature high-quality engine-mounted designs with CNC machined bases providing reliable, leak-proof mounting to the engine case. The precision CNC machining ensures perfect mating surfaces, eliminating the leakage issues commonly experienced with cast or hand-finished mounting bases.

This advanced manufacturing approach delivers consistent dimensional accuracy across all production units, ensuring proper fitment and sealing every time. The precision-machined mounting interface provides long-term reliability and eliminates the need for repeated installation attempts or supplemental sealing measures.

Universal 7th Stud Compatibility

Aero-Classics Continental front-mounted oil coolers feature a hassle-free design accommodating both 7th stud and non-7th stud engine cases. This universal compatibility eliminates confusion during parts procurement and installation, as a single oil cooler model covers multiple engine case configurations.

The dual-compatibility design simplifies inventory management for maintenance facilities and parts suppliers, while ensuring aircraft owners can source replacement oil coolers without detailed engine case specification research. This versatility makes Aero-Classics coolers ideal for fleet operations with mixed Continental engine configurations.

Rigorous Pressure Testing

Every Aero-Classics Continental oil cooler is pressure tested to 300 PSI during manufacturing, far exceeding normal operating pressures to ensure absolute integrity and reliability. This rigorous testing protocol identifies any manufacturing defects or weaknesses before shipment, guaranteeing that each oil cooler will perform reliably throughout its service life.

The high-pressure testing standard provides confidence in system integrity, particularly important for engine-mounted coolers operating in high-vibration environments. This quality assurance process eliminates field failures and ensures operators receive only fully verified, flight-ready cooling components.

Optimized Internal Design

Aero-Classics Continental oil coolers incorporate optimized internal oil flow design maximizing heat transfer efficiency while minimizing pressure drop. The engineered flow paths ensure oil moves through the cooling core in patterns that maximize residence time and thermal contact with cooling fins.

This optimization delivers superior cooling performance compared to conventional designs, maintaining oil temperatures within optimal ranges even during high-power operations and warm-weather conditions. The reduced pressure drop preserves oil system pressure and minimizes parasitic power losses from oil pump operation.

Advanced Corrosion Protection

Corrosion protection per MIL-C-5541, Class 1A ensures long-term durability in aviation environments. This military specification chemical conversion coating provides superior corrosion resistance while maintaining excellent paint adhesion for additional protective finishes. The Class 1A coating protects aluminum cooling cores from oxidation, salt spray, and environmental contaminants throughout the service life.

Finding the Correct Part Number

Identifying the correct Aero-Classics oil cooler requires either your existing oil cooler part number or your aircraft/engine specifications. The Aero-Classics FAA-PMA Eligibility List provides comprehensive cross-reference information:

• OEM Cross-Reference - Enter your existing oil cooler part number (Lycoming, Continental, Cessna, Piper, etc.) to find the Aero-Classics equivalent
• Aircraft Model Search - Look up your aircraft make and model to view all applicable oil cooler applications
• Engine Model Search - Find coolers by engine type and model number for engine overhaul or retrofit applications

Our technical team can assist with part number identification using your aircraft registration, logbooks, or parts manual references. Contact us with your aircraft and engine details for expert application guidance.

Installation Considerations

Aero-Classics oil coolers install using OEM mounting provisions and connections, ensuring compatibility with existing aircraft systems. Installation requires:

• Approved Data - FAA Form 8130-3 supplied with each cooler provides installation approval basis
• Existing Hardware - Most installations reuse original mounting brackets, hoses, and fittings
• Proper Torque - Follow manufacturer specifications for mounting fasteners and oil line connections
• System Testing - Pressure test and operational check per maintenance manual procedures

Installation should be performed by appropriately licensed maintenance personnel following approved procedures. Logbook entries must reference the 8130-3 form and PMA approval for airworthiness compliance.
