Core Viewpoint - The Shaanxi Regulatory Bureau has initiated a comprehensive safety supervision action for parachuting services conducted by out-of-province general aviation companies, focusing on ensuring operational safety [1][2]. Group 1: Safety Regulation Framework - The inspection is based on civil aviation regulations, concentrating on three main areas: system construction, risk prevention, and on-site operations, aiming to establish a safety supervision system that includes "source governance - process control - end closure" [2]. - During the system review phase, the inspection team systematically examined the companies' operational manuals, operational plans, and safety management systems, identifying issues such as missing re-evaluation processes for instructor qualifications and vague emergency release operation guidelines for parachute equipment [2]. Group 2: Risk Assessment and Control - The regulatory bureau proposed a "site characteristics-risk matrix" assessment model, requiring companies to conduct comprehensive safety evaluations based on site-specific meteorological conditions, airspace structure, and ground support facilities [2]. - Companies are required to submit a "Parachuting Operation Risk Assessment Report" utilizing the LEC risk evaluation method to quantify 12 potential risks, including low-altitude wind shear and equipment entanglement, and to develop 18 specific control measures, including a radar early warning mechanism and emergency landing plans [2]. Group 3: On-Site Operational Checks - On-site inspections involved the use of flight data recorders to monitor the entire operational process, from pre-flight preparations to parachute recovery, ensuring compliance with the minimum safety standard of 1,500 meters for jump altitude and testing the load-bearing capacity of safety connection devices [3]. - The Shaanxi Regulatory Bureau has established a dynamic management ledger for out-of-province general aviation enterprises, collecting operational plans in real-time through a national general aviation information platform and implementing tailored supervision for parachuting and aerial photography operations [3].
