DURING REMOVAL OF THE WING LOWER SURFACE REMOVABLE PANELS (T57-10-01-90-801-01/02 ENCLOSED), AND ESPECIALLY DURING REMOVAL OF ACCESS PANELS (PARAGRAPH 3.E.FIG 2), TECHNICIANS NOTICED THAT SCREWS WERE NOT TIGHTENED CORRECTLY ON THE RH MIDDLE SLAT OUTBOARD HOOK R1501CM AND TAB WASHERS WERE NOT BENT ON RH OUTBOARD SLATS ACTUATORS R401CM AND R601CM. ALL DISCREPANCIES CORRECTED BY THE TECHNICIANS DURING REINSTALLATION AND INSPECTION PERFORMED ON ALL COMPONENTS ON BOTH WINGS.
DURING APPLICATION OF SB F7X-630 ON AIRCRAFT, FOUND FEEDER (0V) NUT OF BACK UP WINDSHIELD DE-ICING POWER SUPPLY M1001DG NOT TIGHT.
FOLLOWING REMOVAL OF BOTH WINGS FOR CENTRAL WING PANELS REPLACEMENT, ACCESSES ARE PERFORMED IN THE FEEDER TANKS. PIPES, BRACKETS, PUMPS WERE REMOVED. DURING THESE ACCESSES, COMPONENTS IN THE FEEDERS TANKS ARE DISCOVERED INSTALLED WITHOUT PRC & PAINT PROTECTION IAW AMM. THE AIRPLANE IS JUST OUT OF 2C INSPECTION.
POLLUTION FOUND IN FUEL TANKS AFTER REMOVAL OF BOTH WINGS - FOLLOWING REMOVAL OF BOTH WINGS FOR REPLACEMENT OF LOWER PANELS AFTER 2C INSPECTION PERFORMED IN 2025, WE FOUND CONTAMINATION IN THE WINGS, IN THE CENTRE TANK, IN THE THREE FEEDERSâ TANKS, IN THE FILTERS AND IN THE FUEL PIPES. ANALYSES OF CONTAMINATION CONFIRMED THE PRESENCE OF ALUMINIUM POWDER, MOST PROBABLY GENERATED BY BLENDINGâS IN THE CENTRE TANKS. FOLLOWING MANUFACTURER RECOMMENDATION, ALL TANKS, ALL PIPES AND ALL FILTERS NEED TO BE CLEANED. ADDITIONAL ACCESSES AND INSPECTION IN PROGRESS.
DURING INSPECTION/CLEANING OF THE FUEL FILTERS, THE FILTER OF THE BOOSTER PUMP 2 WAS DISCOVERED IN THE HYDRAULIC BAY, BETWEEN HYDRAULIC PIPES. FILTER WAS NOT INSTALLED AS PER AMM.

APPROXIMATELY AT 12:00 PM I ARRIVED AT KHPN FROM A FLIGHT FROM KATL, AND RENTED A VEHICLE TO KTEB TO ANSWER A CALL FOR MAINTENANCE OVERSITE ON AIRCRAFT S/N-036. THE PIC DECLARED AN EMERGENCY ON LANDING INTO KTEB AIRPORT FROM KOXC AIRPORT. UPON LANDING WITH EMERGENCY LANDING GEAR EXTENSION EXECUTED, THE AIRCRAFT LANDED SAFELY. EMERGENCY VEHICLES WERE ON STANDBY AT THE AIRCRAFT JUST IN CASE, AND THE AIRCRAFT WAS TOWED WITH GEAR PINS IN PLACE, JUST AS A PRECAUTIONARY MEASURE, DUE TO THE AIRCRAFT HAVING NO STEERING AS A RESULT OF EMERGENCY LANDING GEAR EXTENSION BEING EXECUTED. UPON ARRIVAL, AT APPROX. 1330, FOUND AIRCRAFT OUTSIDE WAITING TO BE TOWED TO A HANGAR. AFTER PLACEMENT OF AIRCRAFT, JACKING TOOK PLACE AND GEAR SWINGS ENSUED FOR TROUBLESHOOTING MEASURES. AT ABOUT 1500, AND AFTER SWINGING THE GEAR SEVERAL TIMES, WE COULD NOT GET THE PROBLEM TO REOCCUR BUT THE CODES IN THE CMC STAYED LATCHED. AFTER FURTHER TROUBLESHOOTING DEEP INTO THE CMC AND PULLING CIRCUIT BREAKERS TO CLEAR CODES, CODES WOULD NOT UNLATCH AND CAME BACK, ALL TROUBLESHOOTING POINTED TO THE LGSCU (LANDING GEAR AND STEERING CONTROL UNIT). AT ABOUT 1600, UPON VERIFYING PROBLEM, ORDERED LGSCU AND LUCKILY THEY HAD A PART IN STOCK. FURTHER TESTING AT ABOUT 1700, OF CONNECTORS GROUND AND POWER PIN OUTS FOR THE LGSCU PROVED TO BE POSITIVE. NO OTHER CIRCUITS WERE INVOLVED THROUGH TESTING OF THE INPUT AND OUTPUT OF THE LGSCU. AFTER ARRIVAL OF PARTS, THE TEAM INSTALLED WITHOUT INCIDENT. TESTING AFTER LGSCU INSTALL, WENT WELL. LANDING GEAR PERFORMED WELL WITH THE HYDRAULIC MULE CONNECTED. NO LATCHED MESSAGES WERE ENCOUNTERED DURING CYCLING OF THE GEAR. THE TEAM ALSO TESTED THE SQUAT SWITCHES WITH NO DEFECTS AT THIS TIME. DOWN JACKED THE AIRCRAFT AND FINISHED THE PAPERWORK AT ABOUT 2430.
