Reference: Reg. (EU) No 965/2012 on air operations, Article 6 (4a) and SPO.GEN.005(c)
The term ‘Limited operations’ (used in Regulation (EU) No 2015/1536) refers to certain specialised operations of other-than-complex motor-powered aircraft (SPO-NCO), such as competition flights, flying displays, parachute dropping, sailplane towing and aerobatic flights. Under strict conditions specified in Article 6 (4a) and SPO.GEN.005(c) of Reg. (EU) No 965/2012, those operations may be conducted in accordance with Part-NCO, and in particular subpart E thereof.
AMC1 NCO.GEN.135 (a) (3) specifies that an aircraft may be operated with a permit to fly issued in accordance with the applicable airworthiness requirements.
Thus, in the case of aircraft registered in an EU Member State and used in SPO-NCO, the permit to fly (PtF) is issued in accordance with Commission Regulation (EU) 748/2012 (Part-21 thereof) depending of the purpose.
If the above conditions are met, it is possible to perform the so called ‘Limited operations’ under Part-NCO and its subpart E as long as the aircraft have a PtF for non-commercial flying under Part-21 and the operation is compatible with or is covered by the corresponding flight conditions (FC).
For aircraft registered in a third country, the same applies, except that the PtF/FC must be issued in accordance with that third country legislation.
