Recently, China's indigenously designed and built amphibious aircraft AG600, touted as the world's largest, successfully carried out its first take-off and landing tests on Nov.4.
CNPC Northwestern Rubber supplied 22 sizes of hose productions such as fuel system, power system and so on.
The aircraft, developed and built by the state-owned aircraft firm Aviation Industry Corporation of China, took off and later landed on the water in Hubei province's Jingmen, state-run China Daily reported.
The seaplane took off from the Zhanghe Reservoir at 8:51 am (local time) and stayed airborne for about 15 minutes, said the report which also accompanied the videos of the aircraft's take off.
It will be mainly used for maritime rescue, fighting forest fires and marine monitoring, according to an earlier report by the state-run Xinhua news agency.
The aircraft has passed a series of tests since its maiden flight last December. It successfully finished eight taxiing tests on water at a speed of 80-kilometre per hour and 120-kilometre per hour.
