COMPLETION OF EASA FORM 45B In order to complete and issue a restricted noise certificate, the competent authority should consult the EASA Part 21 Light database of declared noise levels, which contains all the noise data that has been provided and declared by the declarant of the declaration of design compliance under Subpart C of Annex Ib (Part 21 Light). The competent authority should frequently review the EASA Part 21 Light database of declared noise levels to ensure that the declared noise data is still valid and has not changed. This AMC provides recommendations to the competent authority of the Member State of registry that issues restricted noise certificates. Block 1: Member State of registry The competent authority should state its name and country, which should be the same as on the certificate of registration and restricted certificate of airworthiness. Block 2: Restricted noise certificate (declared) The title of the EASA Form 45B is ‘Restricted Noise Certificate (declared)’ Block 3: Document No The competent authority should enter a unique number that identifies each restricted noise certificate in its administration. Such a number facilitates any enquiries with respect to the document. Block 4: Registration marks The nationality and registration marks that are the same as on the certificate of registration and restricted certificate of airworthiness should be entered. Block 5: Manufacturer and designation of aircraft The type and model of the particular aircraft that are the same as on the certificate of registration and restricted certificate of airworthiness should be entered. Block 6: Aircraft serial No The aircraft serial number as given by the manufacturer of the aircraft and that is the same as on the certificate of registration and restricted certificate of airworthiness should be entered. Block 7: Designation of engine For the identification and verification of the aircraft configuration, the designation (including type and model) of the installed engine(s) in accordance with the applicable design data should be entered. Block 8: Designation of propeller For the identification and verification of the aircraft configuration in case of propeller-driven aeroplanes, the designation (including type and model) of the installed propeller(s) in accordance with the applicable design data should be entered. Block 9: Maximum take-off mass (kg) The maximum take-off mass (in kilograms) associated with the declared noise levels of the aircraft should be entered. The unit (kg) should be specified explicitly to avoid any misunderstanding. If the primary unit of mass for the Member State of manufacture of the aircraft is different from kilograms, the maximum take-off mass should be converted in kilograms in accordance with Annex 5 to the Chicago Convention. Block 10: Additional modifications incorporated for the purpose of compliance with the applicable noise certification standards This item should contain as a minimum all additional modifications to the basic aircraft as defined by Blocks 5, 7 and 8 that are essential in order to ensure that the declared noise levels comply with the noise requirements established and made available by EASA in accordance with point 21L.B.61(c) for the declaration of design compliance. Other modifications that are not essential to ensure compliance with the applicable noise requirements but are needed to attain the declared noise levels as given may also be included at the discretion of the certifying authority. The additional modifications should be given using unambiguous references, such as unique part numbers or type/model designators given by the manufacturer of the modification. Block 11: Noise certification standard For the purposes of this form, ‘noise certification standard’ means the noise requirements established and made available by EASA in accordance with point 21L.B.61(c) for the declaration of design compliance of the aircraft. This block should specify the applicable noise requirement(s) and the related noise limit(s) (e.g. ‘ICAO Annex 16, Chapter 10 (10.4b)’). Block 12: Take-off noise level The take-off noise level determined in accordance with the applicable noise requirements should be entered to the nearest tenth of a dB(A). The unit should be specified. Block 13: Statement of compliance Block 14: Date of issue The date on which the document is issued should be entered. Block 15: Signature The officer that issues the restricted noise certificate should sign it. Other items may be added, such as seal, stamp, etc. Additional information:
1.Logo and name of the issuing authority To improve its identification, the competent authority may add its logo or symbol and its name in the box ‘For use by the Member State of registry’.
2.Language If the competent authority issues a restricted noise certificate in a language other than English, it should provide an English translation of that certificate.
