How much in advance should an application for TCO authorisation be submitted before the intended starting date of our EU operations?
TCO.300 (b)(1) requires the application at least 30 days before the intended starting date of operation. Therefore, it is highly recommended that you submit the application well in advance of the intended operation. This will allow for sufficient lead time as, under ART.200(b), EASA may need to conduct a 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 when the technical assessment results in findings that have to be closed before EASA can issue the authorisation.
