Article 30 Aircraft recordsI1
United Kingdom
The following aircraft records must be kept for an aircraft registered in the Territory—
an aircraft logbook;
a separate logbook for each engine fitted in the aircraft; and
a separate logbook for each variable pitch propeller fitted to the aircraft.
A technical log must be kept for every aircraft registered in the Territory for which a certificate of airworthiness is in force.
A record in a form acceptable to the Governor may be kept instead of a technical log in the case of an aircraft of which the maximum certificated take-off mass is 2700 kg or less and which is not operated by the holder of an air operator’s certificate granted under article 94.
Subject to paragraph (5) the technical log referred to in this article must be carried in the aircraft when article 167 so requires and copies of the entries referred to in this article must be kept on the ground.
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 aircraft in a container acceptable to the Governor for that purpose.
The technical log and logbooks referred to in paragraphs (1) and (2) must be in a form acceptable to the Governor and must include the particulars and be kept in a manner specified by the Governor.
