JAR-145 A Regulation for Maintenance Organisations By RC (Bob) Williams February 1999 RC (Bob) Williams is the Maintenance Director of JAA and is tasked with ensuring the introduction and standardization of "European JAR" maintenance...

JAR-145 requires the repair station Chief Executive Officer, known in JAR-145 as the Accountable Manager, to take responsibility for the repair station and sign a statement of commitment to compliance with FAR-145. The CEO must also agree to a number of additional conditions which ensure equivalence to JAR-145.

The reason for placing responsibility for compliance with the CEO recognises the fact that the CEO ultimately determines both the extent of business of the repair station and the extent of compliance with FAR/JAR-145 and makes it easier to remove the JAR-145 acceptance certificate in the case of non compliance. JAA experience has shown that when ever the CEO takes an active interest in the FAR/JAR-145 certificate, the standards improve.

JAR-145 requires compliance with European airworthiness directives and European approved design engineering data, such as modification and repair data. As a consequence compliance with the customer work order, is vital because the USA based repair station may only be aware of FAA approved data.

Further complicating the issue is the fact whilst much FAA approved data may also be European approved, this is not true of all data. Therefore a critical element for the repair station is the need to follow the customer work order and the need to place the responsibility for ensuring appropriate approvals on the customer.

Components that have been obtained from other sources for fitment during maintenance must be accompanied by a JAA Form 1 or a FAA Form 8130-3 or a Canadian Form 24-0078 depending upon the source. For new components traceability to the Original Equipment Manufacturer specified in the Type Certificate Holders Parts Catalogue must be assured. Used components may only be fitted where the last maintenance was carried out by a JAA JAR-145 approved maintenance organisation or a JAA JAR-145 accepted repair station. Note that in the USA only 1000 of the 4500 FAR-145 repair stations are JAA accepted and therefore great care is needed to ensure that only components from the 1000 JAA JAR-145 accepted repair stations are used.

Finally for those repair stations with an airframe rating or a limited airframe rating, there is the need to be aware that almost all aircraft operating in Europe have expiring certificates of airworthiness which means that unlike FAA normal category certificates of airworthiness, they are date limited. Therefore whilst it is primarily the responsibility of the aircraft operator to ensure the certificate is still valid before flight, the repair station should check the date validity of the certificate during maintenance to minimise the potential embarrassment of illegal flight.
