Aircraft
Aircraft was dispatched with MEL 36-11-8- RT PRV SYS Inoperative/open. Just after level off in cruise; Landing Gear Monitor status message. Shortly thereafter LT GEAR green light intermittent. Approximately five minutes later LT GEAR green light steady. Contacted Flight Control via SAT COM advised of the problem and requested a subject matter expert (SME). We explained the event to include no yaw or buffeting and fuel flows were normal and felt the gear was up. The SME said this aircraft has had a history of this problem. Maintenance requested we continue to a maintenance station if we felt comfortable continuing for maintenance. Asked the SME if we can expect any other anomalies related to this problem. He said he didn't know of any. Received amended release for change of destination from my Dispatcher. Advised ATC of change of destination and received a clearance direct the arrival. Checked minimum field length charts for the airport; auto brakes 3. Sufficient Runway 26L. Fifteen miles from the final approach fix selected FLAPS 1; got LE SLAT ASYM. Preformed LE SLAT ASYM with flaps less than 20 while coordinating delay vectors from ATC; did not declare an emergency. Checked non normal configuration landing distance chart. Sufficient runway on 26L. On landing touchdown and rollout; no Lt REV; no Auto Speedbrake; no Autobrakes. Turned off at the end of 26L with 3 & 4's on brake temps. Approximately midfield on taxi back brake temperature 7; status message AIR/GRD DISAGREE; and engines were in flight idle; shut down left engine so we didn't have to ride the brakes. Advised Company Operations and Maintenance of very hot brakes. Turning onto W Taxiway brake temperatures 8 & 9's. Contacted Ground and requested fire/rescue due to very hot brakes. Advised Operations of fire/rescue on the way and requested to park on the ramp away from parked aircraft. Operations said to continue to designated parking spot.
While in operations; another 767 crew told me they had the same events happen to them in another aircraft recently. I have subsequently been made aware of many other event reports within the last six months of LDG GEAR MONITOR; LE SLAT ASYM; and AIR GRD DISAGREE.
A B767-300 diverted after a Landing Gear Green light illuminated in flight. On landing numerous EICAS alerts annunciated; including AIR/GRD DISAGREE; with various aircraft systems indicating the in-flight mode.
