Off the coast of Taiwan, a jet trainer, the AT-5 Brave Eagle, took a nosedive on February 15. The plane had just taken off from Chihhang Air Base in southern Taitung when both of its engines gave up the ghost. The pilot, Major-in-Training Lin Wei, had to bail out in a hurry. Lin had over 1, 000 hours of flight time under his belt, so he was no rookie. After his ejection, he was rescued, but he had to be hospitalized for a bit due to mild hypothermia.

The AT-5 Brave Eagle is a Taiwanese advanced jet trainer. It's based on the AIDC F-CK-1 Ching-Kuo fighter jet and is powered by Honeywell/ITEC F124-200TW turbofan engines. This particular jet had only 183 hours of flight time. It was one of 66 ordered, with 41 already delivered. The AT-5 is designed to be easier to handle than its predecessor, the F-CK-1 Ching-Kuo.

The engines that failed are the same ones used in other jet trainers, like the Aero L-159 ALCA and Alenia Aermacchi M-346 Master. These engines have a lot of flight hours under their belts, over 1, 000, 000 in total. They come with advanced digital controls and monitoring systems to keep tabs on engine health.

So, what caused the crash? Experts suspect a broken fan blade from one engine might have hit the other, causing both to fail. Bird strikes or other causes were less likely, unless the jet had a really bad day and got hit by birds in both engines.

The good news is that the ejection seat saved Lin's life. This was the 7777th life saved by Martin-Baker, the company that makes the ejection seat. The seat used was the Martin-Baker X12J, which can operate from zero speed and altitude up to 600 knots.

Taiwan's Air Force is significant and needs reliable jet trainers to keep its pilot supply pipeline going. The AT-5 Brave Eagle is meant to replace older trainers, the AT-3 and F-5. It can handle both air-to-air and air-to-ground missions, and it can carry a gun. This would be a big deal if the People's Republic of China (PRC) ever tries to invade.

The crash of the AT-5 Brave Eagle seems to be an anomaly. The final cause is unknown, but the suspicion of a broken fan blade taking out both jet engines seems plausible. Taiwan's airspace is constantly being penetrated by the PRC, so Taiwan's air force needs to be ready. The grounding of the AT-5 fleet is a short-term setback, but it's a big question mark for the future.
