Suchaircraft components must be removed by the specified time unless anappropriate release certificate has been obtained in the meantime.Aircraft components from the above sources which are then sold surplus torequirements must be accompanied by the original CertificationDocumentation and maintenance records, as appropriate. Where the originalCertification Documentation is not available, the maintenance organisationmay issue a CAD Form One (if approved for the maintenance of the particularcomponent by the Director-General) endorsed 'Inspected', but it must beremembered that the organisation issuing this CAD Form One bears fullresponsibility for ensuring the original organisation was an Appendix No. 1organisation.6 The Director-General is aware that some Distributors are using a release form whichis almost identical to the Authorised Release Certificate JAA Form One/FAA8130-3/CAD Form One, but omitting the reference to the Regulatory Authority andAuthorisation. Such documents are not acceptable alternatives to the JAA FormOne/FAA 8130-3/CAD Form One.7 CancellationThis Notice cancels Airworthiness Notice No. 17 Issue 7, dated 30 May 2005, whichshould be destroyed.Norman LODirector-General of Civil AviationAN-17 P.531 January 2010
