Missing Logbook
During a pre-purchase inspection of a Lear 35, it was discovered that the number 3 logbook (covering a 5 year period) was missing and could not be located even after an extensive search by the aircraft broker and flight department personnel. Fortunately the aircraft had been placed on V-Log. The number 3 logbook was reproduced in paper form to be included in the permanent aircraft record. The pre-purchase inspection was continued using both V-Log’s digital record research tool and the paper logbooks. Result: Sale of aircraft completed.

Warranty Research
The crew of a GIV contacted maintenance informing them that the left converter had failed in route from New York City to Los Angeles. A quick check of the logbooks on V-Log's data base confirmed that this converter had been changed 11 months previous and was still under warranty. The purchasing department for the Aircraft Management Firm was already in the process of ordering the converter as an exchange unit when they were informed of the warranty situation. The purchase was changed from a normal exchange purchase to a warranty exchange. Result: Savings of $35,000 to the operator.

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. The crew was asked 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 the aircraft to meet Part 135 requirements when it discovered that the S/N on the Nose Wheel Steering Unit did not match the S/N recorded in the aircraft equipment list, or the information maintained by the maintenance tracking company. Since this unit was a Life-Limited Component, with no record of when the part was installed or it's total time, the unit would have to be changed. Utilizing the V-log system; all items with similar Part Numbers were searched through the entire logbook history of the aircraft. V-Log identified twelve logbook entries with similar part numbers. 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. Researching the 8130s then proved that the unit on the aircraft was verifiable, and the logbook entry containing the S/N of the part was in error. Consequently the unit did not have to be changed. Result: Savings of $20,000 to the operator.
