NPA 2016-17

Regular update of certification specifications for standard changes & standard repairs (CS-STAN)

This Notice of Proposed Amendment (NPA) is based on the ‘systematic rulemaking projects’ concept introduced into the European Aviation Safety Agency’s Management Board Decision replacing Decision 01/2012 on the ‘Rulemaking Procedure’ (EASA MB Decision 18-2015 of 15 December 2015). This concept aims at improving the efficiency of the EASA rulemaking process.

The specific objective of this NPA is to propose amendments to CS-STAN taking into account the principles of efficiency and proportionality.

The ultimate goal is to support the operation of the affected aircraft in Europe, reducing the regulatory burden for the embodiment of simple changes and repairs in certain aircraft when fulfilling the acceptable methods, and promoting safety.

This NPA proposes to:

  • provide additional explanations on the use of CS-STAN;
  • introduce new standard changes and update some existing ones; and
  • introduce new standard repairs and update some existing ones

The changes introduced by this NPA are based on lessons learnt and proposals submitted by affected stakeholders, as well as technological innovations from the industry, which can bring safety benefits in a cost-efficient manner.

Overall, this would bring a moderate safety benefit, would have no social or environmental impacts, and may provide major economic benefits by reducing the regulatory burden for the embodiment of simple changes and repairs in certain aircraft when fulfilling the acceptable methods, techniques and practices included in CS-STAN.
