EASA Air Operations Regulation (EU) No 965/2012 Part-SPO (Specialised Operations) applies to any aircraft operation, other than commercial air transport, where the aircraft is used for specialised activities such as agriculture, construction, photography, surveying, observation, patrol and aerial advertisement.

Operators engaged in commercial specialised operations or engaged in non-commercial specialised operations using a complex motor-powered aircraft must submit a declaration to the National Civil Aviation Authority about their operation.

In addition, a commercial operator conducting a high-risk specialised operation must also apply for and obtain an authorisation from the National Civil Aviation Authority .

This is to establish and maintain the required oversight programme for Part-SPO aircraft. The programme will be developed based on the nature and complexity of each operation using available data, including that from any past oversight activities.
