Narrative:

High speed abort due to severe vibration. At 100 KTS aircraft began shaking severely. The captain aborted takeoff and used differential braking to control direction. Nosewheel steering was not available. After clearing the runway and stopping, maintenance personnel determined the nose gear scissors had lost its knuckle pin. It was replaced and then we taxied back to the gate. The vibration caused extensive damage to interior ceiling panels, luggage racks, and east&east equipment racks. Door 3R came open. All procedures and checks were normal during taxi out and subsequent takeoff roll to 100 KTS. At that time the pin for the nose gear scissors must have come out.

Title: A DC10 CREW EXECUTED A REJECTED TKOF AT DTW, WHEN ENCOUNTERING A SEVERE VIBRATION ON TKOF ROLL.

Narrative: HIGH SPD ABORT DUE TO SEVERE VIBRATION. AT 100 KTS ACFT BEGAN SHAKING SEVERELY. THE CAPT ABORTED TKOF AND USED DIFFERENTIAL BRAKING TO CTL DIRECTION. NOSEWHEEL STEERING WAS NOT AVAILABLE. AFTER CLRING THE RWY AND STOPPING, MAINT PERSONNEL DETERMINED THE NOSE GEAR SCISSORS HAD LOST ITS KNUCKLE PIN. IT WAS REPLACED AND THEN WE TAXIED BACK TO THE GATE. THE VIBRATION CAUSED EXTENSIVE DAMAGE TO INTERIOR CEILING PANELS, LUGGAGE RACKS, AND E&E EQUIP RACKS. DOOR 3R CAME OPEN. ALL PROCS AND CHKS WERE NORMAL DURING TAXI OUT AND SUBSEQUENT TKOF ROLL TO 100 KTS. AT THAT TIME THE PIN FOR THE NOSE GEAR SCISSORS MUST HAVE COME OUT.
