GM1 Appendix VII

NOISE CERTIFICATE CONTENT This GM provides guidance on the content of a noise certificate that is issued by the competent authority of the Member State of registry to attest the noise certification of an individual aircraft. The competent authority establishes the noise certificate by completing EASA Form 45. Most of the information for the completion of this Form can be found in the EASA certification noise levels database or in the EASA aircraft type-certificated data sheet for noise (TCDSN). The noise certificate contains information for a unique configuration of the aircraft. In particular, the blocks of the noise certificate cannot contain multiple entries corresponding to alternative weight variants, engine variants and/or noise levels for the same aircraft. If a competent authority issues a noise certificate in a language other than English, it should provide an English translation. Noise certificate content: Block ‘For use by the State of registry’ This Block contains the name or logo of the competent authority issuing the noise certificate. Block 1 State of registry Block 1 contains the name of the Member State of registry issuing the noise certificate. This name should match the name in the certificate of registration and certificate of airworthiness. Block 2 Noise certificate Block 2 contains the title of the EASA Form 45 (‘Noise Certificate’). Block 3 Document No Block 3 contains the unique number allocated by the competent authority of the Member State of registry to allow the identification of the issued noise certificate. This number facilitates any enquiries with respect to the noise certificate. Block 4 Registration marks Block 4 contains the nationality and registration marks of the aircraft as established by the competent authority of the Member State of registry. The marks should match the ones in the certificate of registration and certificate of airworthiness. Block 5 Manufacturer and manufacturer’s designation of the aircraft Block 5 contains the name of the manufacturer of the aircraft and the designation of the aircraft. This information should match the corresponding one in the certificate of registration and certificate of airworthiness. Block 6. Aircraft serial No Block 6 contains the aircraft serial number as given by the manufacturer of the aircraft. This number should match the corresponding one in the certificate of registration and certificate of airworthiness. Block 7 Manufacturer and manufacturer’s designation of the engine(s) Block 7 contains the name of the manufacturer and the manufacturer’s designation of the installed engine(s) to support the identification and verification of the aircraft configuration. Block 8 Manufacturer and manufacturer’s designation of the propeller(s) Block 8 is completed only for propeller-driven aeroplanes. It contains the name of the manufacturer and the designation of the installed propeller(s) to support the identification and verification of the aircraft configuration. Block 9 Maximum take-off mass (kg) Block 9 contains the maximum take-off mass of the aircraft in kilograms (kg), at which the noise levels are certified. The unit ‘kg’ is specified to avoid any misinterpretation. Block 10. Maximum landing mass (kg) Block 10 is completed for aircraft certified in compliance with Chapters 2, 3, 4, 5, 12 and 14 of Volume I of Annex 16 to the Chicago Convention. It contains the maximum landing mass of the aircraft in kilograms (kg), at which the noise levels are certified. The unit ‘kg’ is specified to avoid any misinterpretation. Block 11 Noise certification standard Block 11 contains the reference to the chapter of Volume I of Annex 16 to the Chicago Convention in compliance with which the aircraft is certified for noise. In addition, for aircraft certified in compliance with Chapters 2, 8, 10 and 11 of Volume I of Annex 16 to the Chicago Convention, Block 11 should include the reference to the section specifying the maximum noise levels (limits) that apply to the aircraft. Block 12 Additional modifications incorporated for the purpose of compliance with the applicable noise certification standards Block 12 contains design changes influencing the aircraft’s noise level(s). These are listed in the TCDSN or the EASA certification noise levels database. Block 13 Lateral/full-power noise level Block 13 is completed for aircraft certified in compliance with Chapters 2, 3, 4, 5, 12 and 14 of Volume I of Annex 16 to the Chicago Convention. It contains the certified lateral noise level or the certified full-power noise level as applicable to the aircraft. This level is provided to the nearest tenth of a decibel (dB) together with the related noise level unit. Block 14 Approach noise level Block 14 is completed for aircraft certified in compliance with Chapters 2, 3, 4, 5, 8, 12, 13 and 14 of Volume I of Annex 16 to the Chicago Convention. It contains the certified approach noise level to the nearest tenth of a dB and the related noise level unit. Block 15 Flyover noise level Block 15 is completed for aircraft certified in compliance with Chapters 2, 3, 4, 5, 12 and 14 of Volume I of Annex 16 to the Chicago Convention. It contains the flyover noise level to the nearest tenth of a dB and the related noise level unit. Block 16 Overflight noise level Block 16 is completed for aircraft certified in compliance with Chapters 6, 8, 11 and 13 of Volume I of Annex 16 to the Chicago Convention. It contains the overflight noise level to the nearest tenth of a dB and the related noise level unit. For tilt-rotors certified in compliance with Chapter 13, this information is provided for the vertical take-off and landing (VTOL)/conversion mode only. Block 17 The take-off noise level Block 17 is completed for aircraft certified in compliance with Chapters 8, 10 and 13 of Volume I of Annex 16 to the Chicago Convention. It contains the take-off noise level to the nearest tenth of a dB and the related noise level unit. Block ‘Remarks’ This block can be used by the competent authority to provide any information that is relevant to the noise certificate in complement to the information in the other blocks. For example, this block can be used to indicate the corresponding unique record number from the EASA certification noise levels database. Block 18 Statement of compliance Block 18 contains the statement of compliance of the aircraft with the noise standard as referred to in the noise certificate (Block 11). This statement is provided by default in EASA Form 45. Block 19 Date of issue Block 19 contains the date on which the document is issued. Block 20 Signature Block 20 contains the signature of the officer issuing the noise certificate. Other information may be added such as seal and stamp.
