| Background: | A Fokker 50 operator reported an over-extended main landing gear sliding member after landing. Investigation revealed that an end stop had unscrewed, and that no lockwire was present on the two lockbolts which hold the end stop. Earlier F27 Mark 500 and 600 “RFV” aircraft are equipped with similar design MLG units. This condition, if not corrected, could lead to structural damage of the main gear and loss of control of the aircraft during the landing roll. |
