What is CAPP?

The Certification Authorities for Propulsion Products (CAPP) is a group of engine certification management representatives from the National Civil Aviation Agency of Brazil (ANAC), the European Union Aviation Safety Agency (EASA), the Federal Aviation Administration (FAA) of U.S.A., and Transport Canada Civil Aviation (TCCA).

The CAPP is tasked to identify and pursue, through collaborative activity, certification policy and guidance harmonization opportunities. The full CAPP Charter has been established by the certification director-level Certification Management Team (CMT).

CAPP Harmonization Decisions

CAPP harmonization decisions are documented in closed CAPP Worklist Item (CWI) forms, signed by the CAPP principals from all four authorities. CAPP closure decisions vary depending on the nature of the issue.

Most CAPP CWI forms document an agreed compliance methodology for the subject certification issue. If an applicant follows the documented methodology, and their certificating authority endorses that methodology for a certification project, the other three CMT authorities will accept the methodology for validation. The objective is to offer to industry harmonized compliance approaches, which if adopted, will streamline the validation process. Typically, the subjects addressed in CAPP decision documents are those that have required significant authority and industry resource expenditure to resolve in multiple projects.

The CWI can all be found on the FAA website (English only). Each link to the FAA hosted CWI is embedded in the following table.
