Grant of noise certificates by the CAA
16.—(1) The CAA shall grant a noise certificate in respect of any aeroplane registered in the United Kingdom to which these Regulations apply if it is satisfied on the basis of satisfactory evidence that the aeroplane complies with the standard specified for that aeroplane in these Regulations.
(2) For the purposes of determining the standard applicable to an aeroplane to which regulation 4 or 5 applies where the interval between—
(a)the application for a certificate of airworthiness for a prototype aeroplane and the first issue of a certificate for an aeroplane of that type; or
(b)the application to modify a certificate of airworthiness for a prototype aeroplane and the first issue of a certificate for an aeroplane of that type as modified,
exceeds 5 years, the date on which the application was made shall be deemed to be 5 years before the date of the first issue of the certificate.
(3) The CAA shall grant every noise certificate subject to a condition as to the maximum total weights at which the aeroplane may land or take-off and may grant such a certificate subject to such other conditions relating to standards as to noise as it thinks fit.
(4) Subject to paragraph (5) and regulations 17 and 26 a noise certificate granted by the CAA under these Regulations shall remain in force without limit of time.
(5) A noise certificate granted by the CAA under these Regulations shall cease to be sufficient—
(a)at such time as the aeroplane or any part of it is modified, in any way which affects the ability of the aeroplane to comply with the noise standard required by these Regulations, otherwise than in a manner and with material of a type approved by the CAA either generally or in relation to a class of aeroplane or to a particular aeroplane, and
(b)until the completion of any inspection or test of the aeroplane required by the CAA to be made, which shows that the aeroplane complies with the noise standard required by these Regulations.
