EASA Form 52B – Issue 1

Instructions for the use of the ‘Aircraft statement of conformity – EASA Form 52B’

1.   PURPOSE AND SCOPE

| 1.1. | The purpose of the aircraft statement of conformity (EASA Form 52B) issued under Subpart G or Subpart R of Section A of Annex Ib (Part 21 Light) or under Subpart G of Section A of Annex I (Part 21) is to enable the production organisation to apply for an individual aircraft certificate of airworthiness or restricted certificate of airworthiness from the competent authority of the Member State of registry. |
| --- | --- |

1.1.

2.   GENERAL

| 2.1. | The statement of conformity must comply with the model format, including the 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 render the statement of conformity unrecognisable. If in doubt, consult the competent authority. |
| --- | --- |

2.1.

| 2.2. | The statement of conformity must be either pre-printed or computer generated, but in either case, the printing of lines and characters must be clear and legible. Pre-printed wording is permitted in accordance with the attached model, but no other certification statements are permitted. |
| --- | --- |

2.2.

| 2.3. | The completion of the statement may be either machine/computer-printed or handwritten, using block letters to allow for easy reading. English, and where relevant, one or more of the official language(s) of the issuing Member State, are acceptable. |
| --- | --- |

2.3.

| 2.4. | A copy of the statement and all the referenced attachments are to be retained by the approved production organisation. |
| --- | --- |

2.4.

3.   COMPLETION OF THE STATEMENT OF CONFORMITY BY THE ORIGINATOR

| 3.1. | There should be an entry in all blocks to render the document a valid statement. |
| --- | --- |

3.1.

| 3.2. | A statement of conformity may not be issued to the competent authority of the Member State of registry unless the design of the aircraft and its installed products are approved or the declaration of design compliance is registered with the Agency. |
| --- | --- |

3.2.

| 3.3. | The information required in blocks 9, 10, 11, 12, 13 and 14 may be by reference to separate identified documents held on file by the production organisation, unless the competent authority agrees otherwise. |
| --- | --- |

3.3.

| 3.4. | This statement of conformity is not intended to include those items of equipment that may be required to be fitted in order to satisfy the applicable operational rules. However, some of these individual items may be included in block 10 or in the approved type design or the declared aircraft design. Operators are therefore reminded of their responsibility to ensure compliance with the applicable operational rules for their own particular operations.
