Article 10.5 exemptions: Until Part M is fully applicable CoA of limited duration is considered equivalent to COA of limited duration + ARC21A.183 not applicableOld ARC remains valid but needs to be amended to list the new registration

Except national ARCs: see next slide (FKN)

Transfer of unairworthy aircraft is possible



Once the ARC has been issued after importation from a third country, the new operator shall comply with Part-M, in particular with M.A.305. The aircraft shall freely circulate within the EU Member States in accordance with M.A.903.

One exception:Aircraft having a national ARC as follows:• For aircraft involved in commercial air transport, a national ARC issued prior to 28 September 2008 (will be valid until 28 September 2009 or until expiration, whichever comes first).

• For aircraft not involved in commercial air transport, a national ARC issued following the new article 3.4 contained in Regulation 1056/2008.

According to Regulation 2042/2003 as amended by Regulation 1056/2008 of 27 October 2008, an airworthiness review is not required for new aircraft imported from a third country (M.A.904(a)2).

Statement by exporting Authority regarding airworthiness status of aircraft is a must

Can be export CoACan also be recent CoA

However: Danish article 14.6 (10.5) exemption:Approved by Commission 21.06.2006Alternative to statement by exporting authority: TC holder certifies that aircraft is in compliance with TC, endorsed by State of Design




Historical records: Production standard: initial CoA or export CoAModification standard: changes, STCs and repairs incorporatedMaintenance standard: see presentation by Frederic Knecht (after this slide)

However: Danish article 14.6 (10.5) exemption:

Missing history regarding maintenance can be compensated by maintenance bridging check



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.

Aircraft continuing airworthiness record system – M.A.305




• M.A.305(c): The aircraft log book shall contain:• Aircraft type and registration mark.• Dates, flight time, flight cycles, landings.





• 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.




• 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.




• 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).




• 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.




• 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.




• 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.




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.




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).

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.

Import of a used aircraft from a third country




Aircraft can be in unairworthy condition at time of exportNeed to be addressed on statement by exporting authorityStatement to include exception(s) or waiver(s)Recommendation for issuance of CoA can only be made when aircraft is airworthy
