The Guizhou JL-9, also known as the FTC-2000 Mountain Eagle (Chinese: 山鹰; pinyin: Shānyīng), is a family of two-seat transonic advanced jet trainer and light combat aircraft developed by the Guizhou Aviation Industry Import/Export Company (GAIEC) for the People's Liberation Army Air Force (PLAAF) and the People's Liberation Army Naval Air Force (PLANAF).

[4] Designated the JL-9G, it has strengthened undercarriage, enlarged wing and diverterless supersonic inlets, but has proved to be unsuitable for arrested landings and is limited to land-based operations.

[5] On 5 September 2018, Chinese state-run Xinhua News Agency reported that GAIC had begun mass production of the FTC-2000G variant.

The FTC-2000 uses a new wing, a forward fuselage with side air intakes, and a glass cockpit; the engine, empennage, and mechanical controls of the JJ-7/FT-7 are retained.

[13] On January 16, 2024, a Myanmar Air Force FTC-2000G was shot down by a Kachin Independence Army FN-6 missile in Shan State.
