Finding the right aircraft part numbers is a core task for aviation procurement teams. Accuracy keeps aircraft flying, supports documentation, and maintains FAA compliance. A single-digit error in a part number can lead to costly mistakes or safety issues.
Whether managing replacement parts or sourcing spare parts for future repairs, your team needs a reliable way to search, identify, and verify aircraft parts.
This guide breaks down the search process using tools, databases, and sourcing strategies that support traceability and precision across the aviation supply chain.
What Are Aircraft Part Numbers and Why They Matter
Aircraft part numbers identify specific components across airframes, systems, and models. These numbers ensure buyers select the correct part—especially when parts look similar but are not interchangeable. Every part must be traceable, and the part number is the key to that traceability.
Types of Part Numbers (OEM, PMA, ATA)
Aviation teams most commonly deal with three types of part numbers:
- OEM (Original Equipment Manufacturer): Issued by the original developer or aircraft manufacturer.
- PMA (Parts Manufacturer Approval): FAA-authorized alternatives that meet the same safety standards as OEM parts.
- ATA-based part numbers: Organized by ATA chapters, which group aircraft parts by system or function.
Each type supports sourcing and maintenance from a different angle. Identifying which type you’re dealing with helps your search stay focused.
Why Precision Matters in Aviation Sourcing
In aviation, precision isn’t optional—it’s required. Incorrect part numbers create several risks:
- Delays in the supply chain
- Regulatory compliance failures
- Aircraft grounded due to installation errors
The FAA requires full documentation for each part. Mistakes in sourcing lead to gaps in traceability, which are often caught in audits or inspections.
Using an Aircraft Parts Database for Fast Lookup
Databases simplify finding and verifying part numbers. Instead of manual searches across multiple catalogs, you can confirm part numbers, availability, and documentation in a single platform.
How Databases Organize Part Records
A quality database links a part number to details such as:
- Serial number history
- Component category and function
- Compatible aircraft or systems
- Trace documentation and regulatory status
This structure supports quick filtering, accurate sourcing, and component lifecycle visibility.
Benefits of Using a Parts Database vs Manual Lookup
Manual methods leave more room for outdated or incomplete data. Databases are scalable and often include direct links to suppliers. With internal search logic and batch tools, sourcing teams can operate with more speed and fewer errors.
Common Features to Look for in a Good Database Tool
When evaluating a parts database, look for platforms that:
- Support multi-field searches, including part number, serial number, and system category
- Display documentation status and history
- Link to supplier information and certification status
- Integrate with internal ERP or procurement systems
Reliable databases also include search export options, cross-referencing capabilities, and update logs to ensure system integrity.
Aircraft Parts Locator Tools: How They Work
Locator tools differ from traditional catalogs or databases. When a part number isn’t known or is incomplete, a locator helps fill in the gaps using other identifiers related to the aircraft or system.
Sourcing by Tail Number, Serial, or ATA Chapter
Locators improve search accuracy by using operational or configuration information from the aircraft. For example:
- Searching by aircraft tail number connects to the systems used on that specific aircraft
- A component serial number search reveals the part number, last known status, and traceability record
- Using an ATA chapter search allows teams to find all parts in a given functional area
This flexibility helps when part records are missing or outdated, or when working with third-party maintenance teams that report issues without detailed part data.
When to Use a Locator vs a Catalog Search
A locator should be used when existing data is limited, but sourcing is urgent. Catalogs require known part numbers or product families, while locators allow you to build backwards using aircraft-specific data.
Use a locator when you only have aircraft or tail number information, the part number is incomplete or unverified, or you need stock options from multiple suppliers or global locations.
How DK Turbines Simplifies the Parts Locating Process
DK Turbines offers an integrated locator tool that supports search by part number, aircraft type, or ATA chapter. It returns immediate data on part status, supplier stock, documentation availability, and regulatory compliance. This helps procurement teams act fast while maintaining traceability and confidence in the parts being sourced.
Mastering Aviation Part Search Methods
Procurement teams that understand part systems, approvals, and database logic can find and source accurately—even as aircraft age or data grows complex.
Cross-Referencing OEM vs Alternate Parts
Cross-referencing lets you compare OEM and alternate parts, including PMA options. Most locator and database tools list FAA-approved alternates, allowing you to check the spec, cert, and compatibility in one view. This helps reduce cost and improve availability—while remaining compliant.
Identifying Obsolete vs Available Components
Aircraft parts aren’t always in production. Tools that flag obsolete items help teams avoid wasted time chasing unavailable parts. When a component is discontinued, you can either search for repair options or locate FAA-approved equivalents. Sourcing platforms that show alternate solutions reduce delays and speed up decision-making.
Integrating with Procurement Workflows
Procurement success depends on clean handoffs between search tools and purchasing systems. Systems that integrate with procurement software allow teams to send found parts directly into purchasing workflows, pre-loaded with supplier data, cert tracking, and pricing. This keeps the supply chain moving without added manual steps or entry errors.
Navigating an Aircraft Parts Catalog Efficiently
While databases and locators are dynamic, parts catalogs still serve a purpose—especially when dealing with direct suppliers or manufacturers.
Parts catalogs vary by platform, but the filters commonly allow sorting by:
- Aircraft model and system
- ATA chapter
- Manufacturer
- Condition (new, overhauled, serviceable)
- Certifications available
Using multiple filters focuses your results down to only the parts you can seriously consider—saving time in quoting and correspondence.
How Catalogs Differ from Databases and Locators
Catalogs are static by nature. They show what a supplier offers, but usually do not include inventory levels or traceability details. While useful for pricing estimates or initial research, a catalog can’t replace the depth of a real-time database or locator. Use catalogs mainly for vendor-specific product lists.
Top Tools for Aircraft Parts Lookup in Aviation
Procurement teams often use third-party lookup platforms to access verified aircraft parts from global suppliers. Tools like ILS, PartsBase, OneAero, Aeroxchange, AvRef, and DK Turbines’ locator support searches by part number, aircraft model, ATA chapter, and certification type.
Before relying on any platform, verify that supplier records are current, documentation is available, and part traceability is clearly shown. Missing or outdated data can lead to non-compliant sourcing or delays. A reliable lookup tool should simplify search while supporting regulatory accuracy and supply chain efficiency.
Tips for Using Aircraft Parts Search Databases
Smart database usage helps teams avoid common slowdowns and improves sourcing reliability.
- Use part number prefixes or truncation logic to return series data (e.g., entering “MS2” to retrieve MS21042-06 to MS21042-10)
- Export results to spreadsheets for pricing comparisons or purchasing activity
- Cross-check conditions and documentation columns before initiating a supplier conversation
- Avoid relying on one field—using a combination of part number, ATA chapter, and aircraft model returns better results
