Claim One:
1. A method for assistance in detection of a hard landing of an aircraft, said method comprising: determining an instant of impact of said aircraft on a landing runway from measured parameters; estimating a plurality of said parameters at said determined instant of impact; estimating at least one load criterion for a structural component of said aircraft, said estimating comprising: a step of calculating at least one load criterion for said structural component with at least one computer assisted neural network receiving said estimated parameters as input, wherein said at least one calculated load criterion is compared with at least one first threshold value so as to determine an inspection operation of a first type to be carried out on said structural component, following said landing, wherein said step of determining the instant of impact comprises calculating an instant corresponding to a first impact of the aircraft on the runway based on measured parameters representative of the speed of at least one wheel of said aircraft, and calculating at least one other instant of impact, subsequent to said instant of first impact from a measured parameter of vertical acceleration of said aircraft, and wherein an increment of vertical acceleration is calculated in the vicinities of at least two instants representative of at least two impacts and the instant having the greatest increment is said determined instant of impact.
