FAQ n.19309

B.2 - Can EASA confirm that a single application may be submitted covering several aircraft types or models if the same change is applicable to these aircraft types or models?


In general, one application for TC, RTC, STC, Major and Minor Change can cover several models but not more than one type per certificate. EASA may deviate from this principle,

  • when validating foreign approvals. For the validation of STCs and major changes, EASA shall process the application in the same way as the certifying authority. If the certifying authority has processed such an application as a single application, then EASA shall do likewise;
  • if the technical change is identical for several product types and if no type specific compliance finding is required.
