- asbestos_application
- Finding
- No ship-specific asbestos survey, product inventory, abatement record, condition report, or primary exposure record was located. Machinery or diesel-exhaust insulation, gaskets, packing, electrical insulation, and deck covering are retained only as possible class/era application categories for a WWII Navy diesel landing ship; none is documented aboard USS LSM-220.

- Finding
- The exact CourtListener LSM-220 opinion query returned zero results. The exact USS LSM-220 opinion query did not complete before the Studio command time limit, and both exact-name and hull-number docket queries were stopped by the fleet pacing limiter. No asbestos allegation, other litigation, name collision, discovery record, trial finding, or judgment is carried from the partial sweep.
