Instructions for the use of EASA Form 1

These instructions relate only to the use of the EASA Form 1 for production purposes. Attention is drawn to Appendix II to Annex I (Part‑M) to Regulation (EU) No 1321/2014 and to Appendix III to Annex I (Part‑ML.UAS) to Delegated Regulation (EU) 2024/1107 which cover the use of the EASA Form 1 for maintenance purposes.

1. PURPOSE AND USE

1.1. The primary purpose of the certificate is to declare the airworthiness of new aviation engines, propellers, parts, appliances, CMUs and CMU components (“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 this 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 an approval to install the item in a particular aircraft, engine, propeller, or in a particular CMU in case of CMU components, 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 increased or decreased so long as the certificate remains recognisable and legible. If in doubt, consult the competent authority.

2.3. The user/installer responsibility statement can be placed on either side of the form.

2.4. All printing must be clear and legible to permit easy reading.

2.5. The certificate may either be pre-printed or computer generated but in either case the printing of lines and characters must be clear and legible and in accordance with the defined format.

2.6. The certificate should be in English, and if appropriate, in one or more other languages.

2.7. The details to be entered on the certificate may be either machine/computer printed or hand-written using block letters and must permit easy reading.

2.8. Limit the use of abbreviations to a minimum, to aid clarity.

2.9. The space remaining on the reverse side of the certificate may be used by the originator for any additional information but must not include any certification statement. Any use of the reverse side of the certificate must be referenced in the appropriate block on the front side of the certificate.

3. COPIES

3.1. There is no restriction in the number of copies of the certificate sent to the customer or retained by the originator.

4. ERROR(S) ON A CERTIFICATE

4.1. If an end user finds an error(s) on a certificate, they must identify it (them) in writing to the originator. The originator may issue a new certificate if they can verify and correct the error(s).

4.2. The new certificate must have a new tracking number, signature and date.

4.3. The request for a new certificate may be honoured without re-verification of the item(s) condition. The new certificate is not a statement of current condition and should refer to the previous certificate in block 12 by the following statement: ‘This certificate corrects the error(s) in block(s) [enter block(s) corrected] of the certificate [enter original tracking number] dated [enter original issuance date] and does not cover conformity/condition/release to service’. Both certificates should be retained according to the retention period associated with the first.
