Part-SPO requires each operator to adhere to the relevant parts of the EASA Air Operations Regulation.
Operators must submit a declaration to us about their operation. The declaration will help us to establish and
maintain the required oversight programme for Part-SPO aircraft.
Part-SPO operators engaged in commercial specialised operations or engaged in non-commercial specialised operations
using a complex motor-powered aircraft must submit a declaration to us about their operation. In addition, a commercial
operator conducting a high-risk specialised operation must also apply for and obtain a separate authorisation from
To determine who the operator is you should consider who is responsible for functions such as:
The person responsible for these things is the operator. If the operator is established or resident in the UK
they should make a declaration to the CAA and show their UK address in
the 'Operator' section of the declaration. The Channel Islands and the Isle of Man are not part of the UK for the
purposes of these regulations.
It is possible that the place from which the operations are normally conducted is different from the place at which
the operator is established or residing. If that is the case, there are provisions for that to be shown on the
The declaration must be completed by the 'accountable manager' for the operation.
The accountable manager is a person, appointed by the operator, who has the authority for ensuring that all
activities can be financed and carried out in accordance with the applicable requirements. The accountable manager is
responsible for establishing and maintaining an effective management system. The accountable manager may be the same
person as the operator.
The declaration is open-ended until any changes are made to the operational circumstances.
The declaration must be completed by the accountable manager for the operation. Use this online form to make your
The declaration includes Specific Approvals held by the operator.
More detail covering Specific Approvals can be found in Annex V (Part-SPA) to the EASA Air Operations Regulation.
The Air Operations Regulation contains implementing rules which must be complied with.
In addition, there are acceptable means of compliance (AMCs) published by EASA. The AMCs give more detail regarding the implementing rules and they demonstrate an acceptable means of compliance.
When an operator uses the AMC then there is a presumption of compliance with the rule. However, an operator may develop an alternative means of compliance; they must still fully meet the requirements of the implementing rules, but by way of an alternative means or procedure set out in the operations manual.
As part of the declaration you must state whether or not you use any alternative means of compliance. If you do, you must then state a reference to those published AMCs for which you are using an alternative means of compliance. You do not need to submit the alternative text.
For commercial specialised operations the aircraft must have an EASA Certificate of Airworthiness in accordance with Regulation (EU) No 748/2012.
You will also have to provide details of your Continuing Airworthiness Management Organisation (CAMO), including their approval reference.
If you have multiple aircraft to declare under your operation please click on the add aircraft button for every aircraft.
On completion the form will calculate the fee based on the number of aircraft declared.
If the aircraft is operated under an 'industry standard', such as IS-BAO, this information should be included.
For operators having demonstrated compliance with industry standards, we may adapt our oversight programme accordingly.
