             Current requirements


         According to Part-66, the current licensing system
         includes the following categories of licences for
         aircraft:
            A1, A2, A3, A4
            B1.1, B1.2, B1.3, B1.4
            B2
            C
            National system for sailplanes and balloons

         The qualification requirements for Licences B1.2
         “Piston engine aeroplanes” and B1.4 “Piston engine
         helicopters” are the same for all sizes and
         complexity of aircraft.

             Feedback received by EASA

         Industry and NAAs have requested the creation of an aircraft
         maintenance licence specific for light aircraft, with reduced
         qualification requirements that are better adapted to the reduced
         complexity of these aircrafts.

         In their view, the current system has the following
         shortcomings:
             Currently, there are not enough Part-66 licence holders to
             cover the needs that all the General Aviation industry will
             face when Part-M regulations come into force for aircraft not
             used in Commercial Air Transport.
             The current qualification requirements are too stringent for
             the reduced complexity of light aircraft, imposing also a non-
             reasonable economical impact.
             Current B1.2 and B1.4 licence holders may prefer to develop
             their career on larger piston engine aircraft rather than in
             light aircraft.

             Task 66.022


         A working group was created, with members from
         Industry, NAA´s and EASA.

         4 meetings (2 full days each) already held during May and
         June 2007

         Work still undergoing, with the following envisaged
         calendar:
            NPA ready for external consultation by October 2007.
            End of NPA comment period by January 2008.
            CRD ready for external consultation by March 2008.
            End of CRD comment period by May 2008.
            Opinion issued by June 2008.

             Key aspects of the aircraft maintenance
             licence for light aircraft (currently under
             discussion)

         New categories of aircraft maintenance licences:

             “B3”: applicable to non-pressurised piston engine aeroplanes,
             sailplanes and motor-powered sailplanes with MTOM less
             than 2000 Kg (not applicable to balloons or helicopters)

             “ELA.1”: applicable to European Light Aircraft ELA-1 (as
             defined in the near future by MDM.032, but excluding
             rotorcraft. This classification is still under discussion). This
             licence will be further divided in:
              “ELA.1-Basic”: licence limited to maintenance not
                 including annual inspections and major repairs and
                 modifications.
              “ELA.1-Full”: includes the privileges of “ELA-Basic” plus
                 annual inspections and major repairs and modifications.

             Key aspects of the aircraft maintenance
             licence for light aircraft (currently under
             discussion)
         The “B3” licence may be used in Commercial and Non-
         Commercial Air Transport. However, the definition of European
         Light Aircraft limits the use of the “ELA.1” licence to Non-
         Commercial Air Transport.

         The privileges associated with the “B3” and “ELA.1” licences are
         limited to structure, powerplant and mechanical and electrical
         systems. They will also include work on avionic systems
         requiring simple tests.

         It is not the intention of the working group to create a specific
         licence similar to a B2 for light aircraft.

         For aircraft other than aeroplanes and helicopters it is the
         intention to maintain the possibility of using the corresponding
         Member State regulation for certifying staff (as stated in
         66.A.100) in addition to the “B3” and “ELA.1” licences (when
         applicable).

             Key aspects of the aircraft maintenance
             licence for light aircraft (currently under
             discussion)
         As a summary, possible licences to be used are (in addition to A,
         B2 and C when applicable):
            Piston engine helicopters: B1.4
            Piston engine aeroplanes above 2000 Kg MTOM and all
            pressurised piston engine aeroplanes: B1.2
            Non-pressurised piston engine aeroplanes between 1000 Kg
            and 2000 Kg MTOM: B1.2 or B3
            Non-pressurised piston engine aeroplanes below 1000 Kg
            MTOM: B1.2 or B3 or “ELA.1”
            Sailplanes and motor powered sailplanes below 850 Kg
            MTOM: B3 or “ELA.1” or “National Licence”
            Balloons falling outside the “ELA.1” definition: “National
            Licence”
            Balloons falling inside the “ELA.1” definition: “ELA.1” or
            “National Licence”

        These categories may change depending on the definition of
           “ELA.1” finally agreed by MDM.032.

             Training and experience requirements
             (currently under discussion)


         “B3” licence:

             Basic Knowledge: Examination per revised Appendix I to
             Part-66 (duration of approved Part-147 course: approx.

             Practical Experience: between 1 and 3 years (the same as for
             B1.2). Ref. 66.A.30(a)1

        NOTE: Examination per Appendix I may be replaced by
           examination on “human factors” and “aviation law” if shown
           10 years maintenance experience (at least 80% of the tasks
           of Appendix II to AMC).

             No practical experience required.
