What information is in the WRB header?

• A. TSN, CSN, TSLSV, CSLSV, Serial Number, Owner, Last Shop Visit
• B. Serial Number, Owner, Last Shop Visit
• C. TSN, CSN, TSLSV
• D. TSN, CSN, TSLSV, CSLSV, Serial Number, Owner

Answer: (A)

WRB header stores identification and maintenance status for an asset, combining time/usage metrics with key identifiers. It includes time and usage measures—time since new (TSN), cycles since new (CSN), time since last shop visit (TSLSV), and cycles since last shop visit (CSLSV)—along with who owns the asset (Owner), the asset’s serial number (Serial Number), and the date or record of the last shop visit. This full set lets you quickly see how long the asset has been in service, how much wear or usage it has accumulated, who is responsible for it, and when it was last serviced. The best answer includes all of these fields, whereas the other options omit one or more essential pieces (like Last Shop Visit or one of the time/usage fields), making them incomplete.
