Abstract
A method of correcting, in a composite component, an inappropriate countersink with an inappropriate maximum diameter and/or depth, the inappropriate countersink being provided in the composite component at a fixation opening having a first opening diameter, the method comprising at least the steps of: Preparing a repair patch; Arranging the repair patch on the composite component in an area surrounding the inappropriate countersink; Pressing the repair patch at least partly into the inappropriate countersink by means of an associated pressure tool; and Fixing the repair patch in the inappropriate countersink.

A method of correcting, in a composite component, an inappropriate countersink with an inappropriate maximum diameter and/or depth, the inappropriate countersink being provided in the composite component at a fixation opening having a first opening diameter, the method comprising at least the steps of:
- preparing a repair patch with a repair patch opening having a second opening diameter that is at most equal to the first opening diameter;
- arranging the repair patch on the composite component in an area surrounding the inappropriate countersink, such that the repair patch opening and the fixation opening are at least approximately aligned;
- pressing the repair patch at least partly into the inappropriate countersink by means of an associated pressure tool;
- and
- fixing the repair patch in the inappropriate countersink.
A pressure tool for correcting, in a composite component, an inappropriate countersink with an inappropriate maximum diameter and/or depth, the pressure tool comprising a conical extension that is provided with dimensions that correspond at least approximately to inverted appropriate countersink dimensions.
