Based on the Regulation (Ec) 1178/2011 all of the Member States of the European union and some other countries (eg. Switzerland, Iceland, ..) internationally recognized flight crew licenses of other EASA member states issued in accordance with EASA Part-FCL.

Practice has shown that national procedures of individual aviation authorities varies and there is confusion in the implementation of the Ec 1178/2011 especially during the administration and performing the EASA tests (EASA license proficiency checks, EASA license skill tests and EASA assesment of competence). Many Member States have interpreted the various implementation of the requirement concerning the briefing for the EASA examiners from foregin Member states. 

Due to different national procedures, particularly relating to the administrative procedures of EASA examinations (EASA license proficiency checksEASA license skill tests and EASA assesment of competence) was on 2 April 2014 introduced a document entitled as EASA Examiner Differences document. EASA Examiner Differences document contains all the requirements that are required by the specific Member States be fullfilled by the foregin EASA examiner to conduct the EASA checks (EASA license proficiency checksEASA license skill tests and EASA assesment of competenceon behalf of specific EASA Member state.

EASA Examiner Differences document thus replaces the requirement of Ec 1178/2011 to foregin EASA examiner attend a briefing provided by other EASA Member States on behalf of which the EASA test is supposed to be conducted.

Each EASA aviation examiner must become familiar with the procedures specified in EASA Examiner Differences document before performing EASA exam (EASA license proficiency checksEASA license skill tests and EASA assesment of competence) for an applicant whose flight crew license is issued, by the different EASA Member state than the one supervises the EASA aviation examiner.

EASA examiner differences document is amended published at EASA website.
