Q1095. What aviation regulations govern commercial airline registration document translations?

Answered by the NYC Visa & Translation certified translation team

Commercial airline registration and licensing in Thailand is administered by the Civil Aviation Authority of Thailand (CAAT) under the Air Navigation Act, aligned with ICAO standards. The document translation flows: foreign aircraft documents (certificates of airworthiness, registration, noise certificates, maintenance records) are translated into Thai or English per CAAT's requirements for Thai registration; the operator's manuals and corporate documents for the Air Operator Certificate (AOC) follow CAAT's prescribed formats; and for foreign airlines operating to Thailand, the operating permit documentation goes the other direction. Regulatory points that shape translation: CAAT's requirements implement ICAO annexes, and ICAO's language provisions mean English is generally accepted for technical aviation documents — confirm per document class rather than assuming translation is needed; aircraft registration documents (certificate of registration, certificate of airworthiness) are official certificates whose data fields must be transcribed exactly; and maintenance records supporting airworthiness must be complete and traceable — gaps in translated records raise airworthiness questions. Practice points: for aircraft leasing (the dominant structure for Thai operators), the lease agreement and the lessor's documents follow aviation-finance practice in English, with Thai translation for any filings; the AOC application document set is large — operations manuals, training programmes, safety management system — and is prepared to CAAT's accepted formats. Confirm CAAT's current requirements for the specific application before preparing the document set.
