Civil Aviation Authority of the Philippines
[7] From 1932 to 1936, there were no standard procedures as to the licensing of airmen, registration of aircraft and recording of various aeronautical activities connected with commercial aviation.There were attempts made to register planes and their owners without ascertaining their airworthiness and to record names of pilots, aviator mechanics and other details.[7] In 1933, the office of Technical Assistant of Aviation matters was enlarged into the Aeronautics Division under the Department of Commerce and Industry, the functions of which were embodied in Administrative Order No.244 transferred to the Department of Public Highways the responsibilities relative to airport plans, designs, construction, improvement, maintenance as well as site acquisition.In addition, the Embassy of the United States in Manila warned US citizens in the Philippines "to refrain from using Philippine-based carriers due to 'serious concerns' about the ATO's alleged mishandling of the aviation industry."The VHF omnidirectional range (VOR) used by aircraft for navigating to and from the airport stopped working due to heavy rain and there was no available replacement.
