What Is the Type Certificate Data Sheet?


Scott Campbell

In aviation, the Type Certificate Data Sheet (TCDS) is a crucial document that provides detailed information about a specific aircraft type. It is issued by the regulatory authority or agency responsible for certifying and regulating aircraft, such as the Federal Aviation Administration (FAA) in the United States.

What Does a Type Certificate Data Sheet Contain?

A TCDS contains all the essential technical data and specifications required for an aircraft type to be legally operated. This information helps pilots, maintenance personnel, and regulatory authorities ensure compliance with safety regulations and operational standards.

1. Aircraft Description:

  • Manufacturer
  • Aircraft model
  • Serial number range
  • Number of engines
  • Aircraft category (e.g., transport, utility, etc.)

2. Dimensions and Weights:

  • Wingspan
  • Length
  • Height
  • Gross weight (maximum takeoff weight)
  • Fuel capacity

3. Powerplant Information:

  • Type(s) of engine(s)
  • Ratings (e., maximum continuous power)
  • Fuel type(s)

Certification Basis:

The TCDS also outlines the certification basis upon which the aircraft was certified. This includes referencing specific regulations or airworthiness standards that were used to evaluate and determine the aircraft’s compliance with safety requirements.

Limitations and Operating Information:

The TCDS provides valuable information on limitations and operating procedures for the aircraft. This includes:

  • Maximum speeds (e., VNE – Never Exceed Speed)
  • Stall speeds
  • Maneuvering speeds
  • Weight and balance limits
  • Emergency procedures

Note: Pilots should always consult the aircraft’s specific Pilot’s Operating Handbook (POH) or Flight Manual for the most accurate and up-to-date operating information.

Type Certificate Holder:

The TCDS also includes information about the type certificate holder, which is typically the aircraft manufacturer or a designated organization responsible for managing the type certificate. This may include contact details, address, and other pertinent information.

Importance of Type Certificate Data Sheet:

The TCDS is vital for various stakeholders in the aviation industry:

  • Pilots: The TCDS provides essential information that pilots need to operate an aircraft safely and in compliance with regulations.
  • Maintenance Personnel: It assists maintenance personnel in understanding the specifications and limitations of an aircraft to perform maintenance tasks appropriately.
  • Regulatory Authorities: The TCDS serves as a reference document for regulatory authorities to ensure airworthiness compliance during inspections and certifications.

In Conclusion

The Type Certificate Data Sheet is a comprehensive source of technical data and specifications for an aircraft. It plays a vital role in ensuring safe operations, maintenance, and regulatory compliance. Pilots, maintenance personnel, and regulatory authorities rely on the information provided in the TCDS to perform their respective roles effectively.
