Part 66 - ANNEX III - Maintenance Certifying Staff

identifying the required ‘L’ subcategories.
- Wooden structure covered with fabric is considered to fall under wooden structure. For
aeroplanes with a combination of structures, e.g. metal tubing fuselage and wooden wings,
both experiences ‘metal tube covered with fabric’ and ‘wooden structure’ are required.
- In Group 3, the column ‘MTOM’ intends to assist the competent authorities in identifying the
aeroplane types where the maximum takeoff mass (MTOM) is:
- above 2t requires a B1.2 and B2 or B2L licence, or
- 2t and below requires a B1.2 or B3 and B2 or B2L licence.
- The column ‘NOTE’ in every table includes some useful information, when relevant, e.g.:
- ELA1 or ELA2 aircraft.
- ‘OSD Approved’ or ‘Pending OSD Approval’ means that an OSDMCS (operational suitability
data for maintenance certifying staff) exists or is still under the approval process at the date
of publication of this ED Decision. OSD data is owned by the TCH.
Type training courses approved before the approval of the OSDMCS shall include the OSD
elements within 2 years after the OSDMCS approval.
- STC reference number.
- ‘TC (or STC) not yet released’ means that the type certificate (or STC) has not yet been
released by CAA at the date of publication of this ED Decision, but the final model
configuration is sufficiently mature that the type rating endorsement can be already defined.
In this case, the initial training and licensing may start and be used for approval of type
training courses and Part66 licence endorsement. On the contrary, the associated rating for
the maintenance organisation can be granted only after the type certification of the aircraft
(or after the approval of the STC).
