Instructions for the use of CAA Form 1

drawn to Appendix II to Annex I (Part M) of Regulation (EC) No 2042/2003 which covers the use of the

1. PURPOSE AND USE
1.1. A primary purpose of the certificate is to declare the airworthiness of new aviation
products, parts and appliances (‘the item(s)’).
1.2. 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 acceptable to many airworthiness authorities, but may be
dependent on bilateral agreements and/or the policy of the airworthiness authority.
1.4. 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.
2. GENERAL FORMAT
2.1. The certificate must comply with the format attached including block numbers and
the location of each block. The size of each block may however be varied to suit the
individual application, but not to the extent that would make the certificate
unrecognisable.
2.2. The certificate must be in ‘landscape’ format but the overall size may be significantly
