Key Takeaway
- The Federal Aviation Administration ( FAA ) mandates all aircraft to have a data plate affixed to the exterior fuselage, containing essential identification information such as the builder’s name, model designation, serial number, and type certificate, to ensure compliance and safety.
Aircraft data plates are essential components of any aircraft, serving as unique identifiers that contain critical information about the aircraft’s specifications, manufacturing details, and operational parameters. These small but significant metal plates are typically affixed to the aircraft’s fuselage or another easily accessible location.
Data plates play a crucial role in aircraft identification, maintenance, and regulatory compliance.
This comprehensive guide will explore the importance of aircraft data plates, their contents, legal requirements, and their role in ensuring aviation safety and traceability throughout an aircraft’s operational life.
An aircraft data plate is a small, durable metal plate affixed to an aircraft that serves as its primary means of identification. These plates are typically made of fireproof material, such as stainless steel or aluminum, to ensure longevity and readability even in extreme conditions.
Aircraft data plates contain crucial information about the aircraft, including its make, model, serial number, and other essential details required by aviation authorities. The data plate acts as a permanent record of the aircraft’s identity and is analogous to a vehicle identification number (VIN) for automobiles.
However, aircraft data plates provide more comprehensive information due to the complex nature of aviation and the stringent safety requirements in the aerospace industry.
Key features of aircraft data plates include:
- Permanent attachment : Data plates are securely fastened to the aircraft structure, typically in a location that is easily accessible for inspection but protected from damage or tampering.
- Standardized format : The information on data plates is presented in a standardized format to ensure consistency across different aircraft types and manufacturers.
- Legal requirement : Aviation regulations mandate the presence and maintenance of data plates on all certified aircraft.
- Traceability : The unique identifiers on data plates allow for accurate tracking of the aircraft throughout its operational life, including maintenance records and ownership changes.
- Safety information : Some data plates may include critical safety information, such as maximum takeoff weight or fuel capacity, which is essential for safe aircraft operation.
Aircraft data plates play a vital role in aviation safety, regulatory compliance, and aircraft lifecycle management. They provide a reliable means of identification for maintenance technicians, inspectors, and aviation authorities, ensuring that each aircraft can be accurately tracked and maintained according to its specific requirements and operational history.

Regulatory requirements for aircraft data plates are found in 14 CFR Part 45, Identification and Registration Marking, which is specified in 45.13 Identification Data: the identification must include the builder’s name, model designation, builder’s serial number, type certificate, if any, and production certificate number, if any.
Furthermore, the FAA states where these plates must be placed in Part 45.11: “[T]he aircraft identification plate must be secured to the aircraft fuselage exterior so that it is legible to a person on the ground, and must be either adjacent to and aft of the rearmost entrance door or on the fuselage surface near the tail surfaces.”
Thus, the regulation specifically requires them to be placed on the exterior of the aircraft; it may not be mounted on an interior surface, regardless of whether it is visible from the outside.
Overall, the FAA regulations state that ID plates must be mounted to the exterior of an aircraft and should not be attached in a way that will likely result in it being defaced or removed during normal service. It’s also important to note that they must be attached in a manner that will prevent them from being lost or destroyed in an accident.
Therefore, data plates should not be placed on an inspection cover or access door or any other part of the aircraft that is removed for maintenance purposes or inspections. That’s why the FAA stipulates that plates must be attached to the fuselage.
Aircraft often are subjected to extreme temperatures, sunlight exposure, abrasion, and corrosion, which can affect the readability of data plates. There are some materials that stand up better to these harsh conditions than others, such as Metalphoto photosensitive anodized aluminum .
Data plates constructed of Metalphoto are:
- Lightweight
- Extremely durable
- Offer outstanding resistance to abrasion, extreme temperatures, sunlight, corrosion, and chemicals
Metalphoto has been proven to remain durable for more than 20 years because its image is sealed beneath a sapphire-hard anodic layer. As such, Metalphoto data plates have been qualified by aerospace and government organizations including Boeing, Lockheed Martin, BF Goodrich, NASA, and Honeywell, Inc.
For any number of reasons, an aircraft owner may not have an original identification plate issued by the aircraft manufacturer. Should a data plate become lost, stolen, or damaged during maintenance, a FAA Legal Interpretation issued by their Office of the Chief Counsel states that the owner should “seek a replacement from the aircraft’s original manufacturer.”
In some cases, manufacturers may hesitate to issue new data plates because of product liability exposure, or the manufacturer may be out of business. In that case, the FAA Interpretation states that owners or operators may buy data plates from an approved source after contacting the local Flight Safety Standards District Office or Manufacturing Inspection District Office for assistance and approval in getting a replacement.
The FAA Interpretation also warns aircraft owners against purchasing a reproduction data plate sold online because it may not be produced by the manufacturer or an FAA-approved alternative source and cannot indicate to the FAA that the aircraft conforms to its type design. When the aircraft is missing an approved data plate, it cannot prove conformity and the aircraft is deemed ineligible for a standard airworthiness certificate.
Overall, it is best to avoid purchasing replacement data plates from some sources on the internet because you may be left with a reproduction plate that is not up to par with the FAA standards and regulations. It is better to obtain a replacement data plate from the manufacturer when possible or from an approved source to ensure compliance.
