What is MCH in Aviation? (Manufacturer Certificate Holder)

When we talk about the aviation industry, aircraft manufacturers play a vital role. They are responsible for designing, manufacturing, and testing aircraft to adhere to safety standards. But what is a Manufacturer Certificate Holder (MCH)?

An MCH is a term used to describe a company or organization that designs, manufactures, and distributes aircraft, aircraft engines, or propellers. They have the authorization to construct, test, and certify these products under the Federal Aviation Administration (FAA) regulations.

Manufacturers Certificate Holder’s Certification Process

The certification process for an MCH is rigorous and lengthy. It requires companies to submit documentation to the FAA that proves they have the capability to design and manufacture reliable aircraft. The FAA evaluates companies’ quality control systems, production processes, and management teams to ensure conformity to its stringent safety standards.

Once a company passes this evaluation, they are given permission by the FAA to hold a Type Certificate, Production Certificate, or Supplemental Type Certificate. A Type Certificate is issued for a new aircraft design, while a Production Certificate is given to a manufacturer that produces certified aircraft. Lastly, a Supplemental Type Certificate is awarded for modifications or upgrades to certified aircraft.

It is worth mentioning that the FAA conducts regular inspections to ensure that MCHs are continuously adhering to safety standards. In addition, MCHs need to update and renew their certification regularly to maintain their recognition and permission to manufacture products that fall under the FAA’s jurisdiction.

The Duties of a Manufacturer Certificate Holder

MCHs are accountable for various tasks throughout the life cycle of an aircraft. These responsibilities can range from designing and building the aircraft to providing support for maintenance to ensure its longevity.

Designing and Manufacturing Aircraft

MCHs are responsible for aircraft design, which includes developing plans, making specifications, and devising strategies for construction. The manufacturers also test the aircraft through simulations and actual prototype flights to verify the aircraft’s safety and performance and to ensure that it operates according to FAA regulations. The manufacturers may also be involved in the production and assembly of aircraft components, such as engines, landing gears, avionics, and internal systems.

Providing Support Services

MCHs are also responsible for providing support services for their products. Aircraft warranties are one such service, which provide repair or replacement of parts or products that prove to be defective during the warranty period. Other support services may include customer support, technical support, and training programs for maintenance, repair, and operations personnel.

Maintaining Aircraft Certification

An MCH must continuously maintain the certification for their aircraft, engines, and propellers in compliance with the FAA regulations. They are required to conduct regular inspections and maintenance checks for their products and submit reports to the FAA. MCHs must also notify the FAA if they discover any defects or malfunctions in their products or receive any complaints from customers.

MCH’s Impact on Aviation Industry

Manufacturer Certificate Holders play a critical role in the aviation industry, ensuring that the aircraft, engines, and propellers they design and produce are reliable, safe, and meet FAA regulations. They are at the forefront of innovation and development in the aviation industry.

MCHs strive to improve the efficiency of aircraft systems and their components, test new technologies, and develop new products that meet the regulatory requirements of the FAA. As a result, they are often involved in research and development activities and are vital to the technological advancements in the aviation industry.

Moreover, MCHs are not only responsible for building aircraft but also for generating significant revenue and contributing to the economy. The industry provides jobs in manufacturing, engineering, testing, maintenance, customer service, flight operations, and various support services.


A Manufacturer Certificate Holder plays an essential role in the aviation industry. Their certification process ensures that their products meet the highest safety standards set by the FAA, and they must continuously maintain them to remain in compliance with regulations. Additionally, MCHs have a considerable economic impact, generating revenue and providing jobs in various aviation sectors.

The aviation industry has undoubtedly benefitted and will continue to benefit from the efforts of MCHs in producing high-quality aircraft designs and manufacturing, providing customer and technical support services, and maintaining the aircraft’s safety and certification in compliance with FAA regulations.
