Abstract
An aircraft undercarriage mechanism 20 comprising a first lock member 22 mounted on the undercarriage 14, the first lock member being engageable with a second lock member 24 mounted on a wing 10 of the aircraft. The first lock member 22 comprises a pivotable arm 26 which carries a roller 36. The roller 36 is rotatable and slidable on the arm 26 and is engageable with a catch 48 on the second lock member 24. The provision of the pivotable arm 26 and slidable roller 36 permits relative movement between the lock members 22, 24 when the undercarriage 14 is retracted with the lock members interengaged to minimise transmission of forces created by wing deflection from one lock member to the other.
