Hi guy and gals, here's some info which i'd like to share... mayb u already know he he...
1. An engineer had told me and tat foo about an incidence where there was once a refuelling process whereby a B744 enginner had forgotten to open the the HST isolation valve when doing high fuel load (about more than 130,000kg). As more fuel is added and the valve closed, the excessive fuel enters the center wing tank. Thus, the CG of the aircraft changed and not within the green band take off range. Due to time constraint and aircraft departing soon, the flight dispatch had no choice but to offload about 7 pallets of cargo...
2. While doing fuel sump drain, there are a few observations that u've to take note...
(a) If the water in fuel has a foul odour or brown colour, there is a possibility of microbial contamination. Refer to check on microbial growth (28-10-00/201).
(b) If the fuel has a pink or red colour refer to 747-SL-28-081A to do an inspection on red dye contamination.
