lentokelpoisuusmääräykset

Lentokelpoisuusmääräykset, often referred to as airworthiness directives (ADs) in English, are legally enforceable regulations issued by aviation authorities to address unsafe conditions in aircraft. These directives are mandatory and apply to specific aircraft types, engines, propellers, or appliances. The primary purpose of a lentokelpoisuusmääräys is to ensure the continued airworthiness of aircraft operating within a particular jurisdiction.

When an aviation authority identifies a potential safety issue through incident investigations, service difficulty reports, or other means, they may issue a lentokelpoisuusmääräys. This directive typically specifies the problem, the required corrective actions, and a deadline for compliance. The actions can range from inspections and maintenance tasks to modifications or the replacement of parts.

Aircraft owners and operators are legally responsible for ensuring that their aircraft comply with all applicable lentokelpoisuusmääräykset. Failure to comply can result in severe penalties, including fines and the grounding of the aircraft. The issuance and adherence to these directives are crucial components of a robust aviation safety system, aiming to prevent accidents and incidents by proactively addressing potential hazards. Aviation authorities maintain public databases of issued lentokelpoisuusmääräykset for easy access and transparency.
