Abstract
A method of correcting a twist angle of a gas turbine engine blade includes measuring an existing twist angle of the blade, applying a first angular load to a first end of the blade; and measuring a repaired twist angle of the blade. The first angular load applied to the first end of the blade is based on an empirical correlation between a plurality of angular loads necessary to produce a plurality of twist angle correction values.
