I've always known that wood or wood-core props, like my Catto, need to be retorqued periodically to compensate for seasonal humidity changes. For parts of the country that are pretty humid year round, when (or if) this happens probably doesn't matter very much. However, for those of us in the dry part of the west, where the humidity fluctuations throughout the year are pretty significant, how often should this be done? Just twice yearly (once during the 'dry' season and once during the 'wet' season) or more often that that?
Based on the following monthly average humidity chart for where my plane is based, when would you recommend I do my periodic retorques?
