    Xover cut tit

    In Null u must very careful while moving throttle because u havn't overtemprature protection.

    Stalled start on -15

    Bleed valves sticks ,s.s valve malfunction.

    Xover cut tit

    This is correction of TIT 15 to 60 °c not a cut back its miss consecpt.as per 1c-130B-2-4CL-1. But new JG 1c-130H-2-71JG-00-1 having no 15 to 60°c limit its only 800 to 840 limit of cross over TIT no correction mentioned here.

    NTS Failure

    Yes if NTS system fail prop RPM will be more then power section at that time propeller RPM cross the limit 103.5 . it should be pitch locked and aircraft will yaw opposite direction. If Negative torque increases limit -6000 torque RGB Decoupled from power section. Definitely if outer engine is pitch lock and pilot not confirmed the torque should be more when throttle retarted & aircraft will be yawning opposite direction.we experienced of Pitch lock during NTS system failure during decsanding,Fault is with NTS bracket which not properly actuate NTS system.

    NTS Failure

    NTS system works above flight idle, NTS system work when prop try to rotate engine (during descending,gust load,interruption in TD system,and improper governing) when propeller try to rotate engine (negative torque ) produce this system increase the blade angle when blade angle increase prop RPM decease become in governing range RPM. If ur NTS system fail during descending & NTS system not increasing blade angle through feathering valve and propeller RPM increases obve the pich lock RPM limit ( above 103.5) then propeller should be pitch lock. U can observed pich lock propeller by moving the throttle forward engine RPM follow the throttle movement & torque will be same its indication of pitch lock. REGARDS
  8. It is installed on deverter panel at devert valve on both side utility & booster .regards

    INOPERATIVE WINDSHIELD ANTI−ICING Operation with inoperative windshield anti−icing is permissible provided. 1. The airplane is not flown in known icing. 2. The maximum speed limit below 10,000 feet is 185 KIAS due to possible bird strikes. Descent from high altitude into warm moist air with an inoperative nesa windshield anti−icing system will cause fogging and possible icing of the windshield. To minimize this, increase cabin air temperature and open the pilot’s and copilot’s windshield defogging valves. It is recommended that a gradual descent be made to allow the windshield, which has been cold−soaked at altitude, to warm with ambient cabin air.

    Plz check service news for NESA windows. Tnx regards
  11. Hello T56 Expertise plz any body describe about T56-a-15 signature check on c130 aircraft. Why we done on t56-a-15 engine and wt is purpose of this check. Tnx

    Throttle Quadrant

    Dear moeed u r absolutely right , this jg only deal wuth for O level maintenance but not mention any regarding removal, installtion and inspection inside quardarnt area.

    Turbine rear bearing support casing cracks

    Normally turbine rear bearing support is cracked due to improper installtion procedure of tail pipe , excessive vibration of turbine(improper assembling turbine or vanes cracks), and spacers between turbine and vanes rubbing each other cause of turbine rear bearing support and tail pipe cracking.

    Yes,ABEX type EDP is used on both (with case drain run around and without case drain run around plumbing) NYAB is used only on with case drain & run around plumbing.in vickers type case drain & run around system deactivated. Regards

    To avaoid such type FOD to improve APU panel modification of intake.Direction of intake is toword ground if u little change to upward to minimize the chance of FOD.(for without door APU)

    Hello sir, Le49705 ,GTCP 85-180le .plz check

    #2 Engine failed to air-start

    If u propeller feather or unfeather on ground its means u switch is working, u said ur rpm rewind at 60 % rpm .its mean when u restart engine ur prop angle changed( from 92degree towers flight idle) and prop start rotating .go to an other option it's means switch & circut good properly working .u check other option because rpm not sustained ur engine.sometime malfunction of td system at auto .regards
