FAQ n.44038

I am a US applicant, what are the benefits of the recent TIP revision 6?


TIP revision 6 entered into force on 22 March 2018.

This Revision of the TIP is the first milestone of the implementation of the validation improvement roadmap signed between EASA and FAA in February 2016. All design changes now have common approval path:

  • Accepted (The approval or certificate issued by the certifying authority are automatically accepted by the validating authority) e.g. any design change by the TC or STC holder classified as basic, all design changes classified as minor, PMA Parts, design data for a repair, design data for an alteration except for critical components
  • Streamlined validation (Basic) (The validating authority issues its certificate on the basis of the certificate issued by the certifying authority without technical involvement) e.g. all STCs and subsequent amended STCs
  • Technical Validation (non-Basic) (The technical validation is performed by the validating authority according to a work plan focused on safety emphasis items) e.g. STC, Major Changes

The verifying authority shall issue the corresponding certificate or design approval within fifteen (15) working days for design change and twenty (20) working days for TC of receipt of the complete application.

This revision extends to all repair design their acceptance by the validating authority, removes the last restrictions to the acceptance of ETSO/TSO approvals and introduces the concept of Basic Type Certificates (limited to piston engines and propellers). Amendment 1 to the TIP was signed on 22 June 2018
