Aircraft Equipment Problem Critical
Aircraft Aircraft Damaged
Aircraft
Taxi out; takeoff; and departure were normal. Upon landing; we noticed unusual vibration as the aircraft decelerated through 100 KTS. Captain exited at high speed Taxiway H1. Once at taxi speed; vibration/roughness was still present. At this time; we all deduced we had a possible tire problem with right main gear. The gate was located in very close proximity to the runway exit; so we continued taxi to the gate. Upon postflight inspection; we discovered the front two tires on right main mount had shredded; and the rear two were flat. The only anomaly experienced in-flight was an intermittent ANTISKID advisory message. In the vicinity of 050W; just as we were entering the NAT Track system; the ANTISKID light illuminated twice for approximately 2-3 seconds; then extinguished. We read through the QRH procedure; which stated to avoid using autobrakes; however the light never illuminated for the remainder of the flight. On approach; Captain wisely opted to not use autobrakes; just in case there was an actual problem with the antiskid system. After gate arrival; the flight crew observed the damage. Captain then requested a runway FOD check; and we entered the damage in the logbook.
I was the Relief Pilot on this flight which took off and landed 8 hours 35 minutes later. Flight was uneventful until aircraft rollout which upon slowing below 100 KTS the aircraft appeared or felt as though we were on a rough runway. After exiting the runway; the only indication I had from the observer's seat was a slight rumble or vibration from what appeared to be the right side of the aircraft. Taxi to gate was very short (1 minute or maximum 2). After gate arrival; ground crew alerted us to the main gear tire failure which had occurred.
B767-300 flight crew reports right main gear tire failures after landing. The only indication in flight had been a momentary anti-skid advisory message and the crew elected not to use auto brakes during the landing.
