  2. Restricted Certificate of Airworthiness (R-CoA) Two possibilities: • Based on R-TC; or • Based on Specific Airworthiness Specifications (SAS) Restricted Certificates of Airworthiness

  3. R-CoA Overview of changes introduced by NPA 2008-06 +CRD: • R-TC eligibility limited to special purpose • AP DOA possible for continued validity of TC • R-STC concept • Clarification: SAS and separate design approval • R-CoA based on normal TC + R-STC • Orphan TC becomes design approval based on SAS automatically Restricted Certificates of Airworthiness

  4. R-CoA R-TC eligibility limited to special purpose • Only when a normal TC is not appropriate • Designed for a specific use under defined conditions • Permanent deviations from essential requirements are justified • E.g. agricultural use, fire prevention / suppression, large volume cargo • NOTE: R-TC is not an operational category, i.e. if compliance with ER can be shown: no need for R-TC Restricted Certificates of Airworthiness

  5. R-CoA Other than DOA possible for continued validity of TC • To allow easier maintenance of old TC trying to avoid more orphans • For continued airworthiness activities only • Not for design changes Restricted Certificates of Airworthiness

  6. R-CoA R-STC concept • Allows modification of aircraft with normal TC for a special purpose without the need for applying for a complete new R-TC • R-CoA issued based on TC as modified/supplemented by R-STC Restricted Certificates of Airworthiness

  7. R-CoA Clarification: SAS and separate design approval • In current rules SAS seems to include design approval • In new system made clear: • SAS is similar to TC basis made of one special condition • Separate design approval if aircraft design is shown to be in compliance with SAS Restricted Certificates of Airworthiness

  8. R-CoA Orphan TC becomes design approval based on SAS automatically • For new cases of orphan aircraft: • Design approval based on SAS is automatically generated by law and is the old TC • NAAs will have to revoke CoA and issue R-CoA in stead Restricted Certificates of Airworthiness

  9. R-CoA • Possible grandfathering of national design approvals for R-CoA valid on 28-03-2007 • Need for survey of cases Restricted Certificates of Airworthiness
