China Airlines' flight CAL/CI170 from Taipei/Taoyuan, Taiwan to Toyama, Japan, operated by a Boeing 737-8AL, declared a fuel emergency at 12:40 LT/03:40 UTC, after three failed approach to Toyama due to bad weather. The fuel emergency was declared at about 20km southeast of Toyama Airport at altitude of 4500m (15000ft) while diverting to Nagoya/Chubu International Airport (NGO/RJGG), Japan after failed attempts to land on runway 20 in tailwind conditions at ca. 12:00 LT/03:00 UTC, 12:14 LT/03:14 UTC and 12:27 LT/03:27 UTC. The airplane made a safe landing at Chubu with priority. This occurrence was rated as a serious incident.

It is highly probable that the serious incident was caused by the landing conducted in the situation that the remaining fuel quantity was close to FINAL RESERVE after emergency communications.
It is somewhat likely that consuming a fairy quantity of the reserve fuel when attempting to land at the destination airport multiple times contributed to the remaining fuel quantity at landing, which was close to FINAL RESERVE. Besides, it is highly probable that the aircraft was not in shortage of fuel since the remaining fuel quantity at the time of landing was not below FINAL RESERVE.
