FAA Part 145 Repair Stations

Navigating the World of FAA Part 145 Repair Stations

If you work in the aviation industry, you’ve likely heard of FAA Part 145. It’s a key regulation that governs the facilities responsible for keeping aircraft safe and airworthy. But what exactly is a Part 145 repair station, and how can you effectively find and understand their capabilities?

This guide breaks down the essentials of these certified facilities, from their legal framework to the best ways to find the right one for your maintenance needs.

What is a Part 145 Repair Station?

An FAA-certificated repair station is a facility that has met the rigorous standards outlined in Title 14 of the Code of Federal Regulations (14 CFR) Part 145. This certification is a stamp of approval, signifying that the facility adheres to strict regulations covering its personnel, equipment, and operational procedures.

It’s more than just a certificate; it’s a detailed regulatory framework that ensures every repair, inspection, and alteration performed on an aircraft or its components meets the highest standards of safety and quality. The FAA’s detailed scrutiny provides a strong foundation of confidence in a repair station’s operational integrity.

Decoding Repair Station Ratings

Not all Part 145 certifications are created equal. A repair station’s certificate comes with specific ratings that precisely define the scope of work it is authorized to perform. It’s crucial to understand these ratings to ensure a facility has the exact expertise you need.

The FAA organizes these into six general categories:

  • Airframe: Covers the aircraft structure. Ratings are categorized by aircraft size and construction material (e.g., all-metal large aircraft vs. composite small aircraft).
  • Powerplant: Focuses on engines, with classes for reciprocating engines of varying horsepower and for turbine engines.
  • Propeller: Authorizes work on propellers and their governors.
  • Radio: Covers everything from communication equipment to navigation systems and radar.
  • Instrument: Pertains to flight instruments, divided into mechanical, electrical, gyroscopic, and electronic classes.
  • Accessory: A broad category for various mechanical, electrical, and electronic components.

In addition to these general ratings, a facility may also hold Limited Ratings for specialized maintenance functions or specific articles that don’t fit into the standard categories. For example, a limited rating might be for a particular type of welding or nondestructive inspection (NDI).

How to Find a Certified Repair Station

The FAA provides several official resources to help you find a Part 145 repair station:

  • AVInfo Find a Facility Dashboard: This interactive dashboard on the FAA’s website is the primary tool for searching for individual facilities. It allows you to search by location, rating, and other criteria.
  • Data Downloads Portal: For a comprehensive, downloadable list, you’ll need to visit the FAA’s Aviation Data & Statistics portal. These datasets are typically in a machine-readable format and are best for users who need to perform in-depth analysis.

It is important to remember that these lists are snapshots in time. For critical operational decisions, it’s always best practice to verify a repair station’s current status and ratings directly with the FAA.

Beyond the Basics: Key Considerations

For professionals, choosing a repair station involves more than just finding a name on a list. Here are a few additional factors to consider:

  • EASA Part-145 Approval: Many U.S. repair stations also hold European Aviation Safety Agency (EASA) Part-145 approval. This dual certification is a significant advantage for international operations, as it allows a facility to work on aircraft registered in both the U.S. and the European Union.
  • Advisory Circulars (ACs): The FAA publishes Advisory Circulars to provide guidance on how to comply with regulations. Documents like AC 145-9A (on manuals) and AC 145-11A (on EASA compliance) offer valuable insight into a repair station’s operational expectations. Staying current with these documents is essential for ensuring ongoing compliance.
  • Commercial Data Sources: While the FAA provides the official data, commercial platforms like The 145 offer enhanced features such as market intelligence, average repair costs, and turnaround times, which can be invaluable for strategic business decisions.

In conclusion, successfully navigating the world of FAA Part 145 repair stations requires a keen eye for detail. By understanding the regulatory framework, decoding a station’s specific ratings, and leveraging the right resources, you can make informed decisions that support safe, compliant, and efficient aviation operations.
