On June 6, 2014, the East China Administration of Civil Aviation of China officially issued CTSOA to Qingdao Sentury Tire Co., Ltd. This is the first time that our company has obtained the approval certificate issued by the Administration of Civil Aviation of China, marking that Sentury has become the first Chinese private enterprise to obtain the approval for aviation tires.
The CTSOA certificate is a design and production approval issued by the Civil Aviation Administration of China to manufacturers of items that meet the technical standards. Applicants who have obtained the project approval document stipulated by the technical standards have the right to use the CTSO mark approved to identify their product.
At present, the Boeing 737 series aviation tires developed by Sentury meet the latest standards and the demand for localization of Boeing 737 series tires. After careful design and testing, all performances have reached the domestic leading level and can completely replace similar imported products.
