A component holds an ETSO authorisation and is not an auxiliary power unit. Its manufacturer wants to repair it after service damage. That repair is processed:

  • as a minor or major repair design approved under Subpart M
  • as a change to the ETSO design under point 21.A.611
  • as a change to the type-certificate under Subpart D

Explanation from PART66Online

Point 21.A.431A(e) routes a repair to an ETSO article other than an APU back into Subpart O as a change to the ETSO design under point 21.A.611, so it never enters Subpart M at all. It is equally not a Subpart D change, because the article is approved under its ETSO authorisation, not under a type-certificate.
