INVESTIGATION
In the case that the applicant for a noise certificate or a restricted noise certificate issues an EASA Form 52 or an EASA Form 52B under the privileges granted as an approved production organisation under point 21.A.163(b) of Annex I (Part 21) to Regulation (EU) No 748/2012, then no further action (i.e. no further showing) during the investigation of the aircraft is required before issuing the relevant certificate.

Regulation (EU) 2022/1361
(a) The competent authority of the Member State of registry shall issue or amend noise certificates (EASA Form 45, see Appendix VII to Annex I (Part 21)) and restricted noise certificates (EASA Form 45B, see Appendix II) without undue delay when the applicant has provided the documentation required by point 21L.A.163, and when it is satisfied that the aircraft is in conformity with the applicable noise information determined in accordance with the applicable noise requirements.
(b) For used aircraft originating from another Member State, the noise certificate or restricted noise certificate shall be issued against the corresponding data that is provided by the Agency database on noise levels.
(c) A noise certificate or a restricted noise certificate shall be issued for an unlimited duration. It may be amended only by the competent authority of the Member State of registry.
AMC1 21L.B.172(a) Issuance or amendment of noise certificates
ED Decision 2023/013/R
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.
Regulation (EU) 2022/1361
(a) Upon evidence of a violation of any of the conditions under which the noise certificate or the restricted noise certificate was issued, or that the holder does not comply with the relevant requirements of Regulation (EU) 2018/1139 and the delegated and implementing acts adopted on the basis thereof or with the applicable type design or with the applicable design data of an aircraft for which design compliance has been declared, the competent authority of the Member State of registry shall issue a finding in accordance with point 21L.B.21.
(b) When the type certificate under which the noise certificate was issued is suspended or revoked, or otherwise becomes invalid in accordance with point 21L.A.30, or the declaration of design compliance under which the restricted noise certificate was issued is not any longer registered in accordance with point 21L.B.63, the competent authority of the Member State of registry shall take action in accordance with point 21L.B.22.
