Abstract: Based on the research achievements of aircraft life prediction and life extension for more than forty years, considering national conditions, test conditions, and development of science and technology in China, this paper discusses the individual aircraft of fleet life reliability prediction system and individual aircraft life monitoring technology, including establishing a structure reliability verification system of new aircraft, developing large sample load spectrum flight measurement technology, large sample full-scale aircraft fatigue test technology, modularization and intellectualization of test devices and visual detection devices, and neutron light vision monitoring technology and presents the prospects of establishing aircraft intelligent monitoring platform based on big data to develop the life reliability assessment of aircraft fleet in China into individual life reliability assessment of each aircraft in fleet which is advanced in the world. At the same time ensuring flight safety, the safe service life of aircraft fleet will be extended exponentially. The current situation of small quantity and short life of Chinese aircraft compared to American aircraft will be changed.

Key words: aircraft life, new aircraft structure verification, large sample test, intellectualization of test device, neutron light vision technology, real-time monitoring of individual aircraft, flight safety
