2003-11-18: TSB - A03A0122: The Boeing 767-200 aircraft had just departed Halifax on a flight to Toronto and after the landing gear was selected up the flight crew received a status message 'nose A/G disagree'. When the flaps were selected from 1 to up the flight crew received a red 'flap' and 'overspeed' warning with aural and master warning. The crew selected the flaps back to 1 and the warning cleared. The crew requested and received clearance to return to Halifax and emergency equipment was requested as a precaution. On approach, with the landing gear down, the flight crew received a red 'flap' - 'spoiler' aural and master warning when flaps 25 was selected. The crew re-selected flaps 20 and the warnings cleared. The aircraft landed without further incident. Maintenance advised that both nose gear sensors were in poor condition and that normally if one sensor were bad the other 'good' sensor should prevent these warnings. Both protective cover plates were broken and both sensors were dirty. Maintenance replaced system #1 and system #2 sensors. Adjustments were made and the sensors checked serviceable and the aircraft was returned to service.
