Zusammenfassung:	A method for producing one or more cooling holes 218 in an airfoil 200 for a gas turbine engine 100 is disclosed. The method includes casting one or more hole starter bosses 222 on a suction side 206, a pressure side 208, or both of the airfoil 200, drilling the one or more cooling holes 218 into the airfoil 200 by way of the one or more hole starter bosses 200, and removing the one or more hole starter bosses 222 after drilling the one or more cooling holes 218 into the airfoil 200.
