The invention belongs to the technology of helicopter blade maintenance, and particularly relates to a helicopter blade rear edge reinforcing plate glue failure repair method. According to the helicopter blade rear edge reinforcing plate glue failure repair method, by means of analysis of adhesion strength of bottom glue and a coating adhering to a blade rear edge reinforcing plate and on the basis of the structure characteristics of blade tips, proper adhesive agents are selected by taking condition limitations of flight-line maintenance into full consideration, and the adhesive agents are injected into a glue failure portion through a special syringe for adhesion. By means of a curing lamp heating mode, curing is carried out according to curing conditions of the adhesive agents, and glue failure repair of the blade rear edge reinforcing plate is finished. The method makes up for the blank of rear edge reinforcing plate glue failure repair in the helicopter blade maintenance and repair procedure, improves use and maintenance performance of helicopter blades, is easy to implement in an outfield and is good in repair effect, and repaired blades are verified through flying and can well meet use requirements.
