AMC1 ML.A.305  Aircraft continuing-airworthiness record system    

CAA ORS9 Decision No. 1

(a) Any other forms different from a logbook/log card of keeping the below information could be acceptable. For example, that could be in paper form, a spreadsheet or an IT system.

(b) A log card and status for components other than propeller and engines could be combined in a single document.

(c) If the AD is generally applicable to the aircraft or component type but is not applicable to the particular aircraft, engine, propeller or component, then this should be identified as well as the reason why it is not applicable. There is no need to list those ADs that are superseded or cancelled.

(d) The current status of ADs should be sufficiently detailed to identify the complied AD and/or the due limit.

(e) If the IT system is the only record-keeping system, it should have at least one backup system, which should be regularly updated. Each terminal should contain programme safeguards against the probability of unauthorised personnel altering the database.
