FAQ n.19586

How long should we expect the process to take for the initial TCO authorisation?


Although TCO.300 (b)(1) requires at least 30 days before the intended starting date of operation, it is highly recommended that you submit the application well in advance of the intended operation. This will allow for sufficient lead time, under ART.200(b), EASA might need to extend the assessment period in order to conduct further assessment. Where EASA decides to invite operators for a meeting or to perform an on-site audit, the TCO authorisation process can take several months, especially where the technical assessment results in findings that have to be closed before EASA can issue the authorisation.
