The rationales for promulgation of this Emergency Decree are: whereas Thailand was audited and followed up under the Universal Safety Oversight Audit Program (USOAP) of the International Civil Aviation Organization (ICAO); the International Civil Aviation Organization has changed its auditing method from the methods used in B.E. 2539 which audited compliance with standards and recommended practices only in Annex 1, Annex 6 and Annex 8 of the Convention on International Civil Aviation, and in B.E. 2548 which audited compliance with standards and recommended practices in all safety-related annexes to the method of Continuous Monitoring Approach (CMA) starting from B.E. 2554 onwards; such approach discovered 8 critical areas of Lack of Effective Implementation (LEI) in relation to civil aviation safety oversight, in which case the International Civil Organization disclosed Significant Safety Concerns (SSC) for Thailand, and especially on 18 June 2558 announced refusal of the corrective action plan as proposed by Thailand; and thereby it is necessary and urgent to avoid the impact of such Significant Safety Concerns upon Thailand’s civil aviation safety standards being downgraded by other aviation administrators as well as upon Thailand’s air traffic rights and operations, which will causes serious damage on the aviation industry, public interests and safety, and economic security of the country, and to improve the form, structure, powers and duties of civil aviation bodies of Thailand to be in line with International Standards and to satisfy the requirements and recommendations of the International Civil Organization; therefore, it is necessary to enact this Emergency Decree.
