lufttüchtigkeitsrelevanter

Lufttüchtigkeit, commonly translated as airworthiness, is the status of an aircraft indicating it is in a condition for safe operation and conforms to its approved design and applicable safety standards. In civil aviation, formal recognition of lufttüchtigkeit is granted by national or supranational authorities, such as the Luftfahrt-Bundesamt (LBA) in Germany, the Federal Aviation Administration (FAA) in the United States, or the European Union Aviation Safety Agency (EASA).

Achieving lufttüchtigkeit involves design approval (type certificate) and production conformity, culminating in the issuance of an airworthiness certificate for the aircraft. Type certificates validate that the design meets applicable airworthiness standards; production certificates ensure all aircraft manufactured under the design comply; authorities may issue a certificate of airworthiness after evaluation, and the operator must maintain the aircraft per approved maintenance program.

Continued airworthiness requires ongoing maintenance, inspections, and compliance with airworthiness directives (ADs) for safety-critical issues; any modifications or repairs must be approved (e.g., supplemental type certificates). The operator's maintenance records and the flight readiness are key to sustaining lufttüchtigkeit; if the aircraft deviates from allowed configurations or fails to meet inspection intervals, its airworthiness certificate may be suspended or revoked.

Airworthiness is governed by international standards set by ICAO, and national authorities implement those standards through regulations; certification and maintenance requirements vary by jurisdiction but share common principles, including safety, reliability, and traceability of components.
