Thailand Aviation Regulation: CAAT, Pilot Licensing, Aircraft Import

TL;DR

The Civil Aviation Authority of Thailand (CAAT / สำนักงานการบินพลเรือนแห่งประเทศไทย) regulates civil aviation under the Civil Aviation Act B.E. 2497 (1954), as substantially amended. CAAT was elevated from the former Department of Civil Aviation by Royal Decree in 2015 following ICAO Significant Safety Concerns. Pilot licensing follows ICAO Annex 1 standards; aircraft registration uses the "HS-" prefix. Drones over 2 kg require CAAT registration. Foreign-controlled aviation operations face strict ownership rules — Air Operator Certificates (AOC) require Thai-majority shareholding.

Pilot Licensing

Foreign-licensed pilots can validate or convert their licences subject to CAAT requirements; ICAO-compliant licences from major civil aviation authorities are typically accepted with verification.

Aircraft Registration

• HS
• registration mark for Thai-registered aircraft.
• Owner must be Thai national or Thai-majority company.
• Airworthiness certification under CAAT standards.
• Annual inspection and continuing airworthiness management.

Drone (UAV) Regulation

Aviation Business Operations

• Air Operator Certificate (AOC) — Thai-majority shareholding (51%+) required for scheduled airlines.
• Approved Maintenance Organisation (AMO) — CAAT certification.
• Air Traffic Service Provider certification.
• Foreign Business Act B.E. 2542 (1999) Schedule 2/3 considerations.

Common Mistakes

Avoid these traps:

• Flying drones in restricted airspace without coordination.
• Operating a private aircraft on N-registration in Thailand long-term without import process.
• Assuming foreign pilot licence works without CAAT validation.
• AOC structure that fails Thai-majority test through nominee arrangements.

FAQs

1. Can foreigners own private aircraft in Thailand?Thai aircraft register (HS-) requires Thai-national or Thai-majority owner. Foreign-registered aircraft (N-, G-, etc.) can be operated in Thailand under temporary import arrangements with limits.

2. Are drones for tourism allowed?Recreational under 2 kg with NBTC registration. Tourist areas often have local restrictions. Always check airspace and permission before flying.

3. What about flight schools?Approved Training Organisation (ATO) certification from CAAT. Foreign-controlled flight schools have FBA considerations.

4. Can a foreign pilot become a Thai airline captain?

Subject to CAAT licence validation and the airline's hiring policy. Type-rating and route-check requirements apply per ICAO standards. Some Thai carriers actively hire expatriate captains; others limit to Thai nationals.

5. How is light aviation (Cessna-class) regulated?

Same CAAT framework with category-specific certification. General aviation operations require: registered aircraft, pilot licence, maintenance organisation oversight, and operating bases at CAAT-approved airfields.
