Some self-locking cowling clips are recessed down into the cowling. They are not the type that look like a Phillips screw, but are the type that can be removed with a tool like the TPE657 but the TPE657 will not reach down into the recessed area and go under the head of the clip. If you manage to force it under the head of the clip you can damage the cowling around the recessed part. This is where our recessed cowling clip remover becomes the most useful tool in your toolbox. It will fit easily down into the recessed area and then can be slid under the head of the cowling clip. You then pull up on the center locking part and the clip can be removed.
