Planetary stages of gearboxes remain one of the main issue of helicopter health monitoring because of its complicated vibration signature containing multiple modulated signals. Authors analysed different vibration techniques allowing to step ahead in planetary gearboxes diagnostics and found some limitations for its industrial application. Based on the overview new requirements are considered to advance technique for planetary gears diagnostics. Aiming to develop diagnostic abilities of planetary gears, the paper discusses basic principles of its time-spatial model and main stages of data development, including: data separation by narrowed time window, vibration frequency range choice and transfer functions, spatial mesh modelling and Spatial Time Domain Distribution (STDD). Samples of STDD application on a helicopter gearbox are considered. There are conclusions about practical application availability of STDD for helicopter gearbox diagnosis
