Regulation 21 Exemption where jet aeroplanes accidentally destroyed
After consultation with the Secretary of State, the CAA may grant an exemption from the requirements of paragraph (2) of regulation 10 in relation to an aeroplane which replaces one which has been accidentally destroyed provided that the requirements contained in paragraph (2) are satisfied.
The requirements referred to in paragraph (1) are that—
the operator is unable to replace the aeroplane accidentally destroyed with a comparable aeroplane—
which is available on the market, and
in respect of which there is in force a noise certificate certifying that the aeroplane meets the standards referred to in paragraph (2) of regulation 10, and
the registration of the replacement aeroplane in the United Kingdom is carried out within one year of the date on which the replaced aeroplane was accidentally destroyed.
