  1. UPDATE OF CAA CHANGES& PROPOSALSWHICH COULD AFFECTDESIGN DELEGATIONS Peter Gill Airworthiness Engineer Aircraft Certification Unit

  2. Contents • Update to changes proposed at last Delegation Seminar 2007 • Delegation Issue Presentation • Review of new STC process

  3. Update to 2007 Change Proposals • Major Design Changes – STC’s • As announced at 2007 Seminar • Limitation to prohibit major approvals “that changed data on the TCDS” • Comments requested: • No comments at all – assumed universal agreement

  4. Update to 2007 Change Proposals • Major Design Changes – STC’s • Consistency with other authorities and proposed Rule change • Limitation now proposed as “design change which is classified as major” • Comments requested: • Need mechanism to be able to approve “one-off” major changes • Definition of “major” needs revision

  5. Update to 2007 Change Proposals • Major Design Changes – STC’s • Limitation now proposed as “prohibit approval of design change which is classified as major without prior agreement of the CAA”. • Agreement will be given promptly and at no cost where: • CAA agrees it is appropriate for a “one-off” approval • Not contrary to CAA policy

  6. Update to 2007 Change Proposals • Major Design Changes – STC’s • Areas being looked at before policy can be introduced: • Level at which CAA agreement to approve “one-off” major change is given (needs to be ACU level) • Definition of Major • Have looked at origin of current Rule Part 1 definition • Want to introduce common definition with FAA/EASA • Affects other areas of CAA • Embodied in Rule Part 1 – Not easily changed • Looking at new definition of Major Design Change

  7. Design Delegation Issue Presentation • Presentation available, covering: • Purpose of a Design Delegation • Part 21 – Approval of technical data • Legal basis for Design Delegations • Part 146 – Design organisations • Design Delegation issue process

  8. Review of New STC Process • AC 21-8 introduced February 2009 • Certification Project Plans (PSCP) • Compliance testing • Conformity inspections • Flight Testing • Note: STC applications already existing in February 2009 continue under old process

  9. Review of New STC Process • Certification Project Plans (PSCP) • Need to be taken seriously and compiled carefully • Get CAA agreement on Plan • Should fully detail all areas delegated to Design Organisation or other third parties • Should fully detail any areas where the proposed project differs from AC 21-8

  10. Review of New STC Process • Certification Project Plans (PSCP) Contd • Specify Certification Basis • Until a Changed Product rule is introduced to Part 21, AC 21-8 recommends using the latest certification basis • If you are not proposing to use the latest Rule you should state why in the PSCP • You can go to earlier amendment states for individual paragraphs where it is impractical to meet the latest requirements.

  11. Review of New STC Process • Compliance Testing • Detailed Test Plans • Test Loads • Method of Application of Loads • Measurement of Results (including Instrument Calibration) • Verification of test set-up (Part 146 SOC) • Witnessing of test (authorised by PSCP)

  12. Review of New STC Process • Compliance Testing • Conformity inspections • Test article definition • Manufacturing documentation (Form One or equivalent) • Conformity Certification (8130-9 signed by LAME for minor and IA for major design changes, or as specified in PSCP)

  13. Review of New STC Process • Flight Testing • Specialised type of Compliance Testing • Conformity inspection of Test article • Special-Experimental airworthiness certificate for aircraft • Test Pilot approval of Pilot (AC 19-1) • Detailed Flight Test Plan
