Aircraft maintenance licences include the following categories and, where applicable, subcategories and system ratings:
66.A.3(a) Category A licence
(a) Category A, divided into the following subcategories:
— A1 Aeroplanes Turbine;
— A2 Aeroplanes Piston;
— A3 Helicopters Turbine;
— A4 Helicopters Piston.
66.A.3(b) Category B1 licence
(b) Category B1, divided into the following subcategories:
— B1.1 Aeroplanes Turbine;
— B1.2 Aeroplanes Piston;
— B1.3 Helicopters Turbine;
— B1.4 Helicopters Piston.
66.A.3(c) Category B2 licence
(c) Category B2
The B2 licence is applicable to all aircraft.
66.A.3(d) Category B2L licence
(d) Category B2L
The B2L licence is applicable to all aircraft other than those in Group 1 as set out in Point 66.A.5(1) and is divided into the following ‘system ratings’:
— communication/navigation (com/nav),
— airframe systems.
A B2L licence shall contain, as a minimum, one system rating.
66.A.3(e) Category B3 licence
(e) Category B3
The B3 licence is applicable to piston-engine non-pressurised aeroplanes of 2 000 kg Maximum Take-off Mass (MTOM) and below.
66.A.3(f) Category L licence
(f) Category L, divided into the following subcategories:
— L1C: composite sailplanes,
— L1: sailplanes,
— L2C: composite powered sailplanes and composite ELA1 aeroplanes,
— L2: powered sailplanes and ELA1 aeroplanes,
— L3H: hot-air balloons,
— L3G: gas balloons,
— L4H: hot-air airships,
— L4G: ELA2 gas airships,
— L5: gas airships other than ELA2.
66.A.3(g) Category C licence
(g) Category C
The C licence is applicable to aeroplanes and helicopters.
‘ELA1 aeroplanes’ refers to those aeroplanes which meet the definition of ‘ELA1 aircraft’ that is contained in Article 2(k) of Regulation (EU) No 1321/2014.
‘ELA2 gas airships’ refers to those gas airships which meet the definition of ‘ELA2 aircraft’ that is contained in Article 2(ka) of Regulation (EU) No 1321/2014.
‘Gas airships other than ELA2’ refers to those gas airships which do not meet at least one condition of the definition of ‘ELA2 aircraft’ that is contained in Article 2(ka) of Regulation (EU) No 1321/2014.
NOTE: The ‘ELA2 aircraft’ category includes all ‘ELA1 aircraft’.
The term ‘powered sailplane’ includes:
— those powered sailplanes which may take off solely by means of their own power (self-launching sailplanes); and
— self-sustaining powered sailplanes; and
— touring motor gliders (TMGs).
While the L1C subcategory only includes composite sailplanes, the L1 subcategory includes all sailplanes (composite, metal and wood).
While the L2C subcategory only includes composite powered sailplanes and composite ELA1 aeroplanes, the L2 subcategory includes all powered sailplanes and ELA1 aeroplanes (composite, metal and wood).
In the case of maintenance of mixed balloons (combination of gas and hot air), it is required to hold both L3G and L3H subcategories.
For the B2L licence, a ‘system rating’ is a rating which gives privileges to release maintenance on the aircraft systems covered by the ‘system rating’ and electrical systems.
The sentence ‘shall contain, as a minimum, one system rating’ refers to the fact that the application for a B2L licence should be made for any of the system ratings or any combination of the system ratings specified in 66.A.3.
There is no specific order in which the system ratings should be applied for. Any combination of system ratings is possible.
The description of systems covered by the different system ratings is provided in Appendix I ‘Basic Knowledge Requirements’ under paragraph ‘2. Modularisation’, subparagraph related to ‘Categories B2 and B2L’.
