Correlation must be established between the certificate and the item(s). The originator must retain a certificate in a form that allows verification of the original data. 1.3.

The certificate is not a delivery or shipping note. 1.5. Aircraft are not to be released using the certificate. 1.6. The certificate does not constitute approval to install the item on a particular aircraft, engine, or propeller but helps the end user determine its airworthiness approval status. 1.7. A mixture of production released and maintenance released items is not permitted on the same certificate. 1.8. A mixture of items certified in conformity with ‘approved data’ and to ‘non-approved data’ is not permitted on the same certificate
