COORDINATION WITH OTHER RELATED ACTIVITIES The purpose of coordination with other related activities is to:

(a)harmonise the effects of various approval and certification/oversight teams, especially when dealing with one organisation/applicant/declarant to prevent conflicts of conclusions;

(b)ensure efficient flow of information among the various approval and certification/oversight teams to facilitate the execution of their duties;

(c)optimise the use of EASA’s and the competent authorities’ resources to minimise disruption and cost. Therefore, for a given organisation/applicant/declarant, the responsible Agency teams or staff or the competent authorities of a Member State should arrange for exchange of information with, and provide necessary assistance, as appropriate, to, the relevant competent authority of a Member State or EASA teams or staff — e.g.:

(a)the appropriate certification/oversight teams;

(b)the design organisation oversight team;

(c)the production organisation oversight team;

(d)the maintenance organisation approval team; or

(e)other approval or certification/oversight teams as appropriate. This is considered vital for activities related to the critical design review / safety review prior to issuing the flight conditions for a permit to fly and also for the activities relating to the first-article inspection.
