Keep ordinary cargo-tank reports until the next test or inspection of the same type passes. That is the rule in 49 CFR 180.417(b)(3). A new leak test does not replace a pressure-test report. Build papers and certain MC 330/331 reports have other clocks. Sort the file before you discard anything.

Which clock goes with which file?
49 CFR 180.417(a)–(c) sets out separate rules:
- Owners keep the required build certificates and related papers through ownership and one year afterward.
- Keep ordinary test reports until the next test or inspection of the same type passes.
- Keep the additional MC 330/331 reports covered by paragraph (c) while in the carrier’s service and one year afterward.
A carrier that does not own the tank also needs the required build-paper copies. It keeps them during use and for one year afterward. There are short-term lease exceptions. Read the paragraph that fits the lease.
How would I label the folder?
Use the truck ID and document type. Put the build papers in their own section. Keep each test type together. A failed test is not a successful replacement. This is a filing suggestion, not a new retention period.
Before a sale or lease, compare the packet with paragraph (d). It covers which certificates and reports must be supplied. Do not assume a title folder has them all.
Questions and answers
Does a new annual report replace a pressure-test report?
Only a successful test of the same type meets the ordinary replacement rule. Check what kind of test each report records.
Can we set one disposal date for all truck papers?
No. Build papers, ordinary tests and the additional reports have different rules. Have the fleet’s records owner check the categories before setting dates.
Next step
Have your records owner sort one truck’s file by document type. The bobtail operations page covers the wider truck manual.
