Paragraph 4 Period of validity of certificate of test

Subject to sub-paragraph (ii), a certificate of test required by article 23(1) of this Order in respect of a Commercial Pilot’s Licence (Balloons) shall not be valid in relation to a flight made more than 13 months after the date of the test which it certifies and, in respect of any other licence, shall not be valid in relation to a flight made more than 13 months in Cases A, B, E and H or more than six months in Cases C, D and G after the date of the test which it certifies.

in the case of Cases C, D and G, two certificates of test shall together be deemed to constitute a valid certificate of test if they certify flying tests conducted on two occasions within the period of 13 months preceding the flight on which the functions are to be performed, such occasions being separated by an interval of not less than four months, and if both certificates are appropriate to those functions.
