Assalamualikum all, what's about the Nose landing gear shining portion C130 B ac,i am waiting for yours reply. 

Assalamualikum all,Atm dose not work. Ist all every thing change such as shut of valve, modulator valve,solenoid valve,filter clean,regulator clean,then start the Atm but trip valve tripted finally trip valve change then start the Atm,frequency show 450,then off the atm.at that time full atm change,now this time atm start but atm not carry the load,what happend,please advise me what i do?

The air crew were detailed to carr out a regular cargo msn on route  Bunia to goma in C-130B ac ser no 0962.During the takeoff roll,after 60 knots, capt shifted his  hand to flt con leaving the nose wh   steering as the normal procedure.  but at about 80 knots the ac suddenly swung to the left,the capt immediate decided to abort the msn and ac control by applying differential braking with the help of the co-pltand nose wh steering input.

Finaly we suspected that nose steering control valve malfunction during ac speed 80 knots. What might be the reason can anyone  inform.  Thanks  in advance.
