On March 20, 2015, it obtained the Airworthiness Approval Letter of Civil Aviation Fuel Supply Enterprise issued by the Civil Aviation Administration of China.
The 100LL domestic aviation piston engine fuel that meets international standards has been approved by the Civil Aviation Administration for airworthiness

The scene of the certification ceremony
The company produces 100LL(low lead content) aviation piston engine fuel products that meet international standards and obtain airworthiness approval from the Civil Aviation Administration. On March 20, the Civil Aviation Administration issued a certificate of airworthiness approval to Dongying Hua Ya Guolian Aviation Fuel Co., LTD. (hereinafter referred to as Hua Ya Guolian), an oil product manufacturer. The company is also the first private enterprise in China to enter the field of civil aviation fuel production and obtain the airworthiness approval letter from the Civil Aviation Administration.
Aviation gasoline is the main fuel for the vast majority of general aviation aircraft in the world, of which 100LL is the most used aviation gasoline brand in the world. The use of this gasoline can greatly reduce the phenomenon of lead and carbon accumulation in aircraft engines, effectively reduce the engine failure rate, and improve the safety level of general aviation. Since the 1980s, the world's aviation developed countries have begun to use more environmentally friendly 100LL aviation piston engine fuel, because its lead content is only half of the 100 aviation gasoline, is included in the data list of most piston engines.
Due to the complex refining process of aviation gasoline, high oil quality requirements, relative to the gasoline and diesel market demand is relatively small, there is no enterprise in China to produce 100LL aviation piston engine fuel. The 100LL aviation piston engine fuel independently developed by Huanya International Alliance meets all the requirements of the authoritative American Society for Materials and Testing (ASTM) "Aviation Gasoline Standard" (D910) in the field, and has been approved by the world's major aviation engine companies in writing, filling the gap in domestic aviation gasoline products.
