- Finding type
- vessel_history
- Finding
- The same NAVSEA table lists 'YTM 0777 | LALAKA | 10-Oct-80 | SCRAP SALE.' The batch brief identifies YTM-777 as Lelaka's later hull number; NAVSEA's table itself does not explicitly connect YTB 0514 to YTM 0777 and spells the latter name differently.

- 1980 historical inventory entry
- Limitations
- Same-hull identification comes from the supplied brief, not an explicit cross-reference in this PDF. 'LALAKA' may be a transcription or administrative spelling error; do not treat it as a confirmed alternate vessel name. 'SCRAP SALE' is a disposition category and does not prove physical scrapping; later civilian identity remains unresolved. The PDF itself was inaccessible to direct inspection (HTTP 403). No asbestos claim follows.

- Shipyard industry discussion, asbestos products on American ships and pre-1975 delivery statement
- Finding type
- historical_record
- Finding
- OSHA's 1994 asbestos rulemaking states that asbestos products were used extensively on American ships from the early 1940s through the late 1970s and records OSHA's belief that ships delivered before 1975 contained extensive asbestos insulation. This is era-wide regulatory background only.

- Population
- American shipbuilding and shipyard workers generally
- Limitations
- OSHA makes a general historical statement, not a finding about Lelaka. It supplies no hull-specific product, location, quantity, exposure, disease, or causation evidence. The tug's construction date has not been independently verified from a primary hull record in this batch.

- Finding type
- historical_record
- Finding
- NARA identifies Record Group 19 Bureau of Ships records as a source of U.S. Navy vessel plans and material specifications. A search of NARA's public Ship Plan Index did not locate a Lelaka/YTB-514 entry; an archivist-assisted RG 19 search for tug plans or outfit records remains a lead.

- Repository-level lead only. The online index's omission is not proof that plans or material records do not exist. No box-level record was requested or reviewed, and no asbestos finding follows.

- Finding type
- historical_record
- Finding
- No qualifying hull-specific asbestos survey, abatement record, product document, or litigation record was located in the official sources and completed authenticated CourtListener queries logged below as of 24 September 2026. The two name-search docket hits were unrelated OCR/name collisions; exact-number docket searches and a combined exact-term opinion search returned zero results.

- Finding type
- vessel_history
- Finding
- NAVSEA's 28 June 2011 historical ship table lists 'YTB 0514 | LELAKA | 7-Dec-50 | UNK' under hull ID, hull name, removal date, and final disposition. The table does not explain why this earlier identifier has a 1950 removal date.

- Limitations
- The official PDF could be located in search-indexed text but direct retrieval returned 403, so the row could not be visually checked. 'Removal date' is the table's label, not proof of decommissioning, scrapping, or loss of the tug in 1950. No asbestos information appears in the indexed row.
