We describe the dynamic behaviour of the solar array gears installed on the long-life spacecraft. Impact of the time-dependant deterioration of gearing accuracy caused by the operational wear on the drive's dynamic performance is analysed. The necessity of taking into account the time-dependant deterioration of the gearing accuracy for the estimation of the solar array drive dynamic performance is justified.
