EASA Proposes Parts Approval Revisions
Once implemented, manufacturing requirements for non-critical parts would be alleviated, decreasing manufacturing costs “without affecting safety."

Aircraft parts approvals would be revised under an EASA notice of proposed amendment (NPA) that mandates that parts and appliances need to be accompanied by an EASA approval form, particularly so-called commercial parts not designed exclusively for aviation use. The NPA also proposes to assign a criticality level (CL) for each part based on the safety consequences should the part fail to meet its design standards.
