ATA 3000

ON AROUND FL300 WHILE DESCENDING INTO HVN AND ENTERING INTO IMC CONDITIONS, CREW TURNED ON THE ENGINE ANTI-ICE. IMMEDIATELY AFTER, AN AMBER CAS ENG ANTI-ICE FAIL WAS ILLUMINATING. ALSO CYAN ICE DETECTED CAS APPEARED. THE CREW RAN THE CORRESPONDING CHECKLIST AND EXIT ICING CONDITIONS SIMULTANEOUSLY. (ACCORDING TO THE CHECKLIST, IF THE PROBLEM HASN'T BEEN SOLVED BY CHECKLIST, AIRCRAFT MUST LEAVE ICING CONDITIONS AS SOON AS POSSIBLE) THE CREW INFORMED ATC THAT THEY HAVE AN ANTI-ICE ISSUE AND THEY MUST LEAVE ICING CONDITIONS. CREW FOUND A GAP BETWEEN TWO LAYERS OF THE CLOUDS AT 17,000’ AND HEADING 180 DEGREES AND REQUESTED ATC TO MAINTAIN THAT ALTITUDE AND HEADING. ABOUT 3 MINUTES LATER, THEY HAVE NO CHOICE BUT TO DESCEND INTO THE CLOUDS AND TRY TO FIND A CLEAR AREA. WE ASK ATC TO DESCEND ASAP INTO A LOWER ALTITUDE AS POSSIBLE. ATC DECLARED AN EMERGENCY FOR THAT IN ORDER TO GIVE PRIORITY IN TAKING THE AIRCRAFT TO DESTINATION AS SOON AS POSSIBLE. AT AROUND 10,000 L ENGINE ANTI-ICE STARTED WORKING AND CAS DISAPPEARED. ACCORDING TO THE ANTI-ICE SYNOPSIS PAGE, L ENGINE ANTI-ICE WAS WORKING AT 10,000’ AND BELOW. AIRCRAFT WAS GIVEN HEADING FOR THE ILS 02 INTO KHVN. AIRCRAFT LANDED SAFELY AT KHVN, NO CAS MESSAGE ILLUMINATED UPON LANDING.

AIRCRAFT INCURRED SYSTEMS FAILURES @ FL450 WITH 6 SOULS ON BOARD, 2 PILOT, 4 PAX WRITE UP AS INCURRED BY THE PILOTS. FL450 CRUISE LEFT PFD GOES DARK AP DISENGAGES NO YD MESSAGES BUT I CAN FEEL IMMEDIATELY THAT THE AIRPLANE STARTS TO SWAY BACK AND FORTH. CAS: AMBER L BUS FAIL AMBER L PITOT HEAT FAIL AMBER STALL PROTECTION FAIL CHECKLIST BOTTOM LINE IS LAND AS SOON AS PRACTICAL. DIVERTED TO KMCI ON THE DESCENT WE GOT AMBER L HYD TEMP HIGH WITH TEMPERATURE RISING AND REACHING 103°C. AT THAT POINT DECLARED AN EMERGENCY AND LANDED SAFELY IN KMCI. WE ARE OF THE ASSUMPTION THAT THE SYSTEM IN QUESTION COULD BE THE IAPS (INTEGRATED AVIONICS PROCESSING SYSTEM) WHICH COORDINATES THE TALKING OF ALL RELATED SYSTEMS. WE CURRENTLY HAVE TECHNICIANS FROM WEST STAR ON SITE AND WORKING THE EVENT TO GET A BETTER PICTURE OF WHAT COULD HAVE CAUSED THIS. DOWNLOADS FROM THE MAINTENANCE SYSTEM WILL BE PROVIDED TO BOMBARDIER FOR VERIFICATION.

DIVERTED TO KMCI ON THE DESCENT WE GOT AMBER L HYD TEMP HIGH WITH TEMPERATURE RISING AND REACHING 103°C. AT THAT POINT DECLARED AN EMERGENCY AND LANDED SAFELY IN KMCI. TECHNICIANS ACCESSED THE AIRCRAFT, INSPECTED THE LH DCPC AND NOTED SEVERE ELECTRICAL BURNING SMELL. THE TERMINALS, SPECIFICALLY T4 IN THE DCPC WAS NOTED TO BE BURNED AND THE RING TERMINAL COMPLETELY MELTED THROUGH. AT THIS TIME WE ARE UNABLE TO PROVIDE FURTHER SYSTEM INFORMATION TO BOMBARDIER DUE TO THE LACK OF ELECTRICAL POWER APPLICATION ON THE AIRCRAFT. WE WILL BE REPLACING THE ENTIRE DCPC ALONG WITH THE FULL LENGTHS OF WIRING FOR T4, T10 AND T9. ONCE THIS HAS BEEN COMPLETED WE CAN PROVIDE BOMBARDIER WITH THE REQUIRED DOWNLOADS TO SEE HOW THE SYSTEM HANDLED THE EVENT. THIS APPEARS TO BE LOCALIZED TO THE DCPC. UNABLE TO VERIFY THE TIGHTNESS OF THE CONNECTORS IN THE DCPC AS THEY HAVE BEEN WELDED IN PLACE. WE HAVE NO RECORD OF THIS COMPONENT EVER BEING REMOVED FOR ACCESS AND IT WAS THE ORIGINAL UNIT INSTALLED IN 2011 FROM THE FACTORY. BOMBARDIER BELIEVES THE HIGH HYDRAULIC TEMP COIULD BE ATTRIBUTED TO THE EXCESS HEAT GENERATED FROM THE ARCING TERMINALS AS THEY ARE POSITIONED DIRECTLY UNDER THE LH RESERVOIR.
