Aircraft continuing airworthiness record system
At the completion of any maintenance, the certificate of release to service required by point M.A.801 or point 145.A.50 shall be entered in the aircraft continuing airworthiness records. Each entry shall be made as soon as practicable but in no case more than 30 days after the day of the maintenance action.
The aircraft continuing airworthiness records shall consist of:
• an aircraft logbook, engine logbook(s) or engine module log cards, propeller logbook(s) and log cards, for any service life limited component as appropriate, and,
• when required in point M.A.306 for commercial air transport or by the Member State for commercial operations other than commercial air transport, the operator’s technical log.
The aircraft type and registration mark, the date, together with total flight time and/or flight cycles and/or landings, as appropriate, shall be entered in the aircraft logbooks.
The aircraft continuing airworthiness records shall contain the current:
• status of airworthiness directives and measures mandated by the competent authority in immediate reaction to a safety problem;
• status of modifications and repairs;
• status of compliance with maintenance programme;
• status of service life limited components;
• mass and balance report;
• list of deferred maintenance.
In addition to the authorised release document, EASA Form 1 or equivalent, the following information relevant to any component installed (engine, propeller, engine module or service life-limited component) shall be entered in the appropriate engine or propeller logbook, engine module or service life limited component log card:
• identification of the component; and
• the type, serial number and registration, as appropriate, of the aircraft, engine, propeller, engine module or service life-limited component to which the particular component has been fitted, along with the reference to the installation and removal of the component; and
• the date together with the component’s accumulated total flight time and/or flight cycles and/or landings and/or calendar time, as appropriate; and
• the current paragraph (d) information applicable to the component.
An owner or operator shall ensure that a system has been established to keep the following records for the periods specified:
• all detailed maintenance records in respect of the aircraft and any service life limited component fitted
• the total time in service (hours, calendar time, cycles and landings) of the aircraft and all service life-limited components
• the time in service (hours, calendar time, cycles and landings) as appropriate maintenance of equivalent work scope and detail
• the current status of airworthiness directives applicable to the aircraft and components, at least 12 months after the aircraft or component has been permanently withdrawn from service; and
• details of current modifications and repairs to the aircraft, engine(s), propeller(s) and any other component vital to flight safety, at least 12 months after they have been permanently withdrawn from service.
AMC M.A.305 (d) Aircraft continuing airworthiness record system
The status of current modification and repairs means a list of embodied modification and repairs together with the substantiating data supporting compliance with the airworthiness requirements. This can be in the form of a Supplemental Type Certificate (STC), SB, Structural Repair Manual (SRM) or similar approved document.
The substantiating data may include:
(a) compliance programme; and
(b) master drawing or drawing list, production drawings, and installation instructions; and
(c) engineering reports (static strength, fatigue, damage tolerance, fault analysis, etc.); and
(d) ground and flight test programme and results; and
(e) mass and balance change data;...
