Regular update of the Certification Specifications for Standard Changes and Standard Repairs — CS-STAN Issue 4

The objective of this Notice of Proposed Amendment (NPA) is to support general aviation (GA) in Europe by reducing the administrative burden for the embodiment of simple changes and simple repairs in certain aircraft when applying the acceptable methods, techniques, and practices defined in CS-STAN, and thus to promote safety.

Taking into account the principles of efficiency and proportionality, this NPA proposes to amend CS-STAN in order to: 

  • update and complement the contents of Subpart A (General); 
  • introduce some new Standard Changes (SCs) and update some existing ones; and 
  • update some existing Standard Repairs (SRs). 

The amendments introduced by this NPA are based on lessons learned and proposals submitted by affected stakeholders, as well as technological innovations from the industry, which can bring safety benefits in a cost-effective manner. Overall, this is expected to bring a moderate safety benefit, to have no social or environmental impacts, and it may provide major economic benefits by reducing the administrative burden for the embodiment of simple changes and simple repairs in certain aircraft.
