Water System Troubleshooting
A BBJ was on a trip to Asia. The crew contacted maintenance on a Sunday morning to inform them that the water system had failed and that there was no pressure available anywhere in the aircraft. Maintenance asked the crew for verification of system component (valve) positions and other troubleshooting tasks. Maintenance then went on-line to the V-Log system to look at the system schematics and also to look at the cabin handbook to see what the crew had available as a reference. With the ability to look at these two books and explain to the crew what was required to troubleshoot the system, the problem was found and corrected in time for the flight that afternoon. Result: Aircraft dispatched on time.

Component S/N Verification
A Part 135 operator was in the process of conforming an aircraft to meet Part 135 requirements when they discovered that the S/N on the Nose Wheel Steering Unit did not match the S/N recorded in the aircraft logbook. Since this unit was a Life-Limited Component, with no record of when the unit was installed or total time on the unit, the unit would have to be changed. Utilizing the V-log system; the entries were researched individually, a logbook entry was found with a Nose Wheel Steering Unit replacement, but with a slightly different S/N than the unit installed on the aircraft. The logbook entry was proven to be in error. Consequently the unit did not have to be changed. Result: Savings of $25,000 to the operator.
