Method for predicting an operational malfunction in an aircraft equipment, the parameters of the equipment being monitored and recorded during flights by measurements or signals, the aircraft further including an equipment breakdown detection unit, the breakdown also being recorded in the aircraft memory. During maintenance phases between flights, measurements and breakdowns are retrieved on a programmable computer to form a database, and (a) a data analysis program is executed, a first time, to determine a set of pairs of parameter pairs whose signals develop positively over time in a correlated manner and in the absence of a breakdown, and (b) once the set of parameters pairs has been determined, a detection program is executed to calculate correlations for the pairs in the determined set of pairs and, when the calculated correlation value of one pair for a given flight falls below a predetermined positive detection threshold, a malfunction is reported.
