GM 66.A.20(b)4 Privileges
CAA ORS9 Decision No. 1
1. Holders of a Part-66 aircraft maintenance licence may not exercise certification privileges unless they have a general knowledge of the language used within the maintenance environment including knowledge of common aeronautical terms in the language. The level of knowledge should be such that the licence holder is able to:
— read and understand the instructions and technical manuals used for the performance of maintenance;
— make written technical entries and any maintenance documentation entries, which can be understood by those with whom they are normally required to communicate;
— read and understand the maintenance organisation procedures;
— communicate at such a level as to prevent any misunderstanding when exercising certification privileges.
2. In all cases, the level of understanding should be compatible with the level of certification privileges exercised.
