Part 21 Subpart J DOA

• Main principles
• To establish a qualified framework for the
  various activities related to the compliance
  demonstration with applicable requirements
• To set the basis to enable the Authorities to
  accept statements, from DOA organisations, that
  the regulations have been complied with
• Only for applicant or holder of a design approval
  (TC, STC, changes, repairs)

Part 21 Subpart J DOA

• Rationales for JAR 21 Subpart JB deletion (1)
• not immediately related to design approval
  certificates
• considered outside of the scope of the Basic
  Regulation, Article 5(2)(d)
• absence of privileges
• more a kind of label, facilitating relationship
  between subcontractors and main design
  organisations in charge of the certification of
  complete products.

Part 21 Subpart J DOA

• Rationales for JAR 21 Subpart JB deletion (2)
• not considered as a prime responsibility of an
  Aviation Authority.
• same objective can be achieved by Industry
  supplier/subcontractor qualification and overview
  systems, under Industry direct control.
• Ref. CRD Part 21, 33 to 36

11
Part 21 Subpart J DOA

• Agreement to re-discuss the concept
• to keep for the first issue of Part 21 only
  design organisation approvals directly related to
  certificates
• to recommend for further Agency activity the
  evaluation of possible new privileges taking into
  account the actual Industry environment
• This will allow a complete assessment of the
  situation and the development of appropriate
  solutions, fully in line with the functions to be
  exercised by an Aviation Safety Agency.
