A drive lever arrangement comprising:
- a unison ring which comprises a groove;
- a drive lever;
- a drive lever pin comprising a transversal throughbore hole, said drive lever pin for connecting the drive lever to the unison ring;
- and
- a clip,
- wherein the drive lever pin connects the drive lever to the unison ring, and
- wherein the clip is inserted in the groove through the throughbore hole of the drive lever pin, and engages with the groove of the unison ring to inhibit rotation of the drive lever pin, or
- wherein the drive lever pin further comprises a circumferential collar element, wherein the circumferential collar element is adapted to engage with the groove, and wherein the clip is inserted through the throughbore hole of the drive lever pin.
A method of placing a drive lever pin in a drive lever arrangement, wherein the drive lever arrangement comprises a unison ring comprising a groove, a drive lever, and a drive lever pin comprising a transversal throughbore hole, said drive lever pin for connecting the drive lever to the unison ring, wherein the method comprises:
