FIELD: aviation.
SUBSTANCE: invention relates to evaluation of aircraft flight safety. Evaluation is performed taking into account time of service to last overhaul using equivalent damageability of wing and coefficient of technical state, depending on degree of corrosion and biological damage of parts and units of aircraft by formula: 
where α1 is a coefficient which characterises rate of accumulation of fatal wear; TRC is time of operation of aircraft to last overhaul; kEQ is wing load equivalent; t is time of operation of aircraft after last overhaul; KTS is coefficient of technical state, Tmezhrem is assigned overhaul life of aircraft; w is a weight coefficient whose value is determined based on processing results of expert information; γ is a calculated coefficient.
EFFECT: technical result is possibility of quantitative evaluation of flight safety of aircraft equipment.
