AOC Application Process
The IAA has a well defined process for dealing with applications for Air Operators certificates. This process is explained to prospective applicants in detail at a preliminary application meeting.
An undertaking which wishes to proceed with an application for an AOC should apply to the following address for an information pack. A non-refundable fee of €250 should accompany the application which will be offset against the total fee levied for investigations and work completed by the IAA in respect of the AOC application.
