Technical LogU.K.
15.—(1) This article applies to public transport and aerial work aircraft registered in the United Kingdom.
(2) Subject to paragraph (3), a technical log shall be kept in respect of every aircraft to which this article applies.
(3) In the case of an aircraft of which the maximum total weight authorised is 2,730 kg or less and which is not operated by the holder of an air operator's certificate granted by the CAA under article 6(2) a record approved by the CAA (in this article, article 14(5)(c) and in Schedule 6 called “an approved record”) may be kept instead of a technical log.
(4) Subject to paragraph (5), at the end of every flight by an aircraft to which this article applies the commander shall enter in the technical log or the approved record as the case may be—
(a)the times when the aircraft took off and landed;
(b)particulars of any defect which is known to him and which affects the airworthiness or safe operation of the aircraft, or if no such defect is known to him, an entry to that effect; and
(c)such other particulars in respect of the airworthiness or operation of the aircraft as the CAA may require;
and he shall sign and date the entries.
(5) In the case of two or more consecutive flights each of which begins and ends—
(a)within the same period of 24 hours;
(b)at the same aerodrome, except where each such flight is for the purpose of dropping or projecting any material for agricultural, public health or similar purposes; and
(c)with the same person as commander of the aircraft;
the commander may, except where he becomes aware of a defect during an earlier flight, make the entries specified in paragraph (4) at the end of the last of such consecutive flights.
(6) Upon the rectification of any defect which has been entered in a technical log or approved record in accordance with paragraphs (4) and (5) a person issuing a certificate of release to service issued under this Order or under Part 145 in respect of that defect shall enter the certificate in the technical log or approved record in such a position as to be readily identifiable with the defect to which it relates.
(7) Subject to paragraph (8) the technical log or approved record shall be carried in the aircraft when article 86 so requires and copies of the entries required by this article shall be kept on the ground.
(8) In the case of an aeroplane of which the maximum total weight authorised is 2,730 kg or less, or a helicopter, if it is not reasonably practicable for the copy of the technical log or approved record to be kept on the ground it may be carried in the aeroplane or helicopter, as the case may be, in a container approved by the CAA for that purpose.
(9) Subject to article 91, a technical log or approved record required by this article shall be preserved by the operator of the aircraft to which it relates for a period of at least 2 years after the aircraft has been destroyed or has been permanently withdrawn from use, or for such shorter period as the CAA may permit in a particular case.
