A system and methods for locating and drilling determinate assembly (DA) holes using a coordinate measuring device (CMD) are disclosed. A system includes a CMD having a probe tip, a guide element having a reference hole for receiving the probe tip, and a drill bushing having a drill bit guide hole for accurately drilling a DA hole at a target position. Methods for locating and drilling DA holes comprise steps of: calibrating a CMD; inserting a CMD probe into a reference hole of a guide element; positioning the CMD probe and guide element at a target position on a part; maintaining the guide element at the target position; removing the CMD probe from the guide element; inserting a drill bushing into the reference hole of the guide element; and drilling a DA hole in the part, utilizing a drill bit guide hole located in the drill bushing.

An adjustable drill template has a base plate and a plurality of drill blocks. The drill blocks are movably coupled to the base plate. The drill blocks can move along the length of the base plate so that the drill blocks can be configured to conform to a desired hole pattern. A locking device coupled to each drill block will hold each drill block in a desired position.
