an airworthiness review is not required for new
aircraft imported from a third country (M.A.904(a)2).

Aircraft continuing airworthiness
record system – M.A.305
CURRENT REQUIREMENTS:
• M.A.305(b): The aircraft continuing airworthiness record system
shall contain:
• Aircraft log book.
• Engine log book(s) or engine module log cards.
• Propeller log book(s).
• Log cards for service life limited components.
• Operator’s technical log.
Service life limited component: This covers not only those components
with a life limit but also those with a maintenance schedule.
Certificates of Airworthiness
European Aviation Safety Agency
Aircraft continuing airworthiness
record system – M.A.305
CURRENT REQUIREMENTS:
• M.A.305(c): The aircraft log book shall contain:
• Aircraft type and registration mark.
• Dates, flight time, flight cycles, landings.
Certificates of Airworthiness
European Aviation Safety Agency
Aircraft continuing airworthiness
record system – M.A.305
CURRENT REQUIREMENTS:
• M.A.305(d): The aircraft continuing airworthiness record system
shall contain the current:
• Status of ADs and other safety measures.
• Status of modifications and repairs.
• Status of compliance with the maintenance programme.
• Status of service life limited components.
• Mass and balance report.
• List of deferred maintenance.
Certificates of Airworthiness
European Aviation Safety Agency
Aircraft continuing airworthiness
record system – M.A.305
• Currently, M.A.305(e) contains the records and information required
for any installed component.
• However, Opinion 06/2005 (still pending Commission approval)
proposed to limit these requirements to engines, propellers,
engine modules and service life limited components.
Certificates of Airworthiness
European Aviation Safety Agency
Aircraft continuing airworthiness
record system – M.A.305
• M.A.305(e) as amended by Opinion 06/2005 requires the following
documents and information:
• EASA Form 1 or equivalent.
• Identification of the component.
• 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 removal and installation of
the component.
• The date together with the particular component accumulated
total flight time and/or flight cycles and/or calendar time, as
appropriate.
• The information contained in M.A.305(d).
Certificates of Airworthiness
European Aviation Safety Agency
Aircraft continuing airworthiness
record system – M.A.305
• M.A.305(h) as amended by Opinion 06/2005 requires the following
records to be kept during the following periods:
• All detailed maintenance records in respect of the aircraft and
any service life limited component fitted thereto, at least 24
months after the aircraft or component was permanently
withdrawn from service. Until such time as the information
contained therein is superseded by new information
equivalent in scope and detail but not less than 24 months
after the aircraft or component has been released to
service.
Certificates of Airworthiness
European Aviation Safety Agency
Aircraft continuing airworthiness
record system – M.A.305
• M.A.305(h)....
• The total time in service (hours, calendar time, cycles and
landings) and flight cycles as appropriate of the aircraft and all
life limited components, at least 12 months after the aircraft or
component has been permanently withdrawn from service.
• The time and flight cycles as appropriate , since last scheduled
maintenance of the component subjected to a service life limit, at
least until the component scheduled maintenance has been
superseded by another scheduled maintenance of equivalent
work scope and detail.
Certificates of Airworthiness
European Aviation Safety Agency
Aircraft continuing airworthiness
record system – M.A.305
• M.A.305(h)....
• The current status of compliance with the maintenance programme
such that compliance with the approved aircraft maintenance
programme can be established, at least until the aircraft or
component scheduled maintenance has been superseded by other
scheduled maintenance of equivalent work scope and detail.
• The current status of ADs applicable to the aircraft and components,
at least 12 months after the aircraft or component has been
permanently withdrawn from service.
• Details of current modifications and repairs of 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.

record system – M.A.305
KEY POINTS EXTRACTED FROM M.A.305 (as modified by Opinion
06/2005):
• The EASA Form 1 or equivalent must be retained as part of the
aircraft continuing airworthiness records only for engines, propellers,
engine modules and service life limited components.
• This must be retained by the operator until the maintenance action
has been superseded by a new action equivalent in scope and detail,
but not less than 24 months since the maintenance action was
released.
NOTE: This requirement is different and independent from the one
contained in 145.A.55, where the maintenance organisation shall
retain during 2 years since the release to service all detailed
maintenance records of the aircraft or any component.
Certificates of Airworthiness
European Aviation Safety Agency
Import of a used aircraft from a third
country
The M.A.305 requirements described before are only applicable to aircraft
contained in Article 1 of 2042/2003, that is:
•Aircraft registered in a Member State, or
•Aircraft registered in a third country and used by an operator for which
a Member State ensures oversight of operations.
As a consequence, they are not applicable to the previous life of an
aircraft being imported into the EU (as long as it was not used by an EU
operator). This means that:
• An EASA Form 1 or equivalent can not be expected for the installed
components.
• Other releases to service or serviceable tags may be acceptable to the
importing competent authority, depending on possible bilateral
arrangements with the exporting country.
• Missing information will be subject to a bridging programme, proposed
by the CAMO issuing the recommendation and agreed by the authority
(may include re-certification of components).
Certificates of Airworthiness
European Aviation Safety Agency
Import of a used aircraft from a third
country
The position of the Agency is that these records should only be
requested for engines, propellers and service life limited components,
not being required for on-condition components.
