Twin Commander 680FL/P: Aircraft Parts

Yes! All airplane components offered by Pilot John International meet or exceed FAA and EASA standards for airworthiness and quality. Each aircraft part is sourced from trusted OEMs and approved manufacturers, ensuring compliance with aviation safety regulations. Documentation, such as Certificates of Conformance (CofCs) and FAA Form 8130-3s (where applicable), is available, ensuring the traceability and integrity of every item we sell.

Reputable aircraft parts suppliers should maintain certifications such as ISO 9001 or AS9100, which confirm compliance with aerospace quality management standards. PJi is ISO 9001:2015 certified for the distribution and maintenance of aircraft ground support equipment, avionics, and parts. Working with a certified aircraft parts distributor ensures that you receive reliable, high-quality aircraft components that meet the strictest aviation safety requirements.

Every aircraft part should include appropriate airworthiness documentation. At PJi, we provide a Certificate of Conformance (CofC) and an FAA Form 8130-3 (when applicable) at no additional cost. Additional documents – such as Supplemental Type Certificates (STCs), Service Bulletins, and traceability reports – may also be available upon request.

Aircraft part traceability ensures that each component has a documented history of manufacturing, inspection, and certification. This documentation provides transparency and helps verify compliance with FAA and international aviation standards. Maintaining traceability supports accountability, improves safety, and allows maintenance teams to track part performance throughout its service life.

When choosing aircraft components, consider certification, compatibility, and quality assurance. Selecting parts that meet FAA or EASA approval ensures airworthiness and regulatory compliance. You should also verify that the part matches your specific aircraft make and model to ensure proper fit, function, and performance.

OEM (Original Equipment Manufacturer) parts are produced by the same company that originally designed and built the component for the aircraft. PMA (Parts Manufacturer Approval) parts are FAA-approved alternatives that must meet or exceed the same standards for fit, form, and function as the OEM part. Both OEM and PMA aircraft engine parts, hydraulic parts, and landing gear components are reliable options, but PMA parts often provide excellent value and availability without compromising performance or safety.

An alternate aircraft part number refers to a cross-referenced identifier used by manufacturers, distributors, or regulatory agencies to denote the same or equivalent component. For example, a single component may carry different part numbers depending on the manufacturer or the revision level. Understanding alternate part numbers simplifies sourcing from multiple aircraft parts distributors and ensures the correct match for your aircraft’s configuration.

Use PJi’s Shop by Aircraft feature to filter compatible parts by aircraft make and model. This tool makes it easy to find the correct parts for your specific aircraft. If you’re unsure, our aviation specialists can confirm compatibility – just provide your aircraft’s make, model, and serial number for personalized support.

Commonly replaced parts include aircraft tires, brake assemblies, and landing gear parts, as well as aircraft batteries, filters, hoses, and aircraft lights. These components endure significant wear during flight operations and must be inspected frequently to maintain airworthiness. Routine replacement of these and other consumable items helps prevent premature failure, extends the lifespan of equipment, and ensures the safe and efficient performance of all aircraft hydraulic systems and flight-critical subsystems.

Inspection intervals depend on the part and the aircraft’s maintenance schedule. Critical systems, such as landing gear, hydraulic components, and electrical equipment, require regular checks, while other items follow intervals based on flight hours or calendar time. Regular preventative maintenance ensures that critical components, including wheels and brakes, aircraft lighting, and engine parts, operate safely and efficiently.

Certain minor replacements – such as changing aircraft lights, batteries, or tires – can sometimes be performed by certified pilots or operators, provided they follow FAA maintenance rules. However, most replacements involving engine parts, hydraulic systems, or aircraft landing gear must be performed by licensed A&P mechanics or authorized maintenance technicians. Always refer to your Aircraft Maintenance Manual (AMM) and FAA guidelines for proper authorization.

Yes. Certain aircraft parts are non-returnable due to safety and certification requirements. Any part holding a PMA, TSO, or STC that has been used, tested, or installed cannot be returned for refund or exchange. Additionally, items with limited shelf life – such as aircraft batteries, aircraft tires, and engine mounts – are non-returnable to ensure product integrity and compliance with airworthiness regulations. For full details, please visit our Returns Policy page or contact our aviation specialists for assistance.

Warranty terms vary by manufacturer and product type, but most aircraft parts suppliers provide coverage for defects in materials or workmanship for a specified period. Warranty details are listed on each product page or can be confirmed by contacting PJi’s aviation support team. Our specialists can help you understand coverage for individual items prior to purchasing.
