8. [8]VA Board of Veterans' Appeals, Citation Nr 0735173, Docket No. 04-17 159 (decided Nov 8, 2007) - ORDER granting service connection for asbestosis [other_primary]

   Finding type

   litigation_documented

   Finding

   Adjudicated VA Board of Veterans' Appeals decision names this hull by hull number in an asbestos-exposure claim decided on the merits. Service personnel records established the veteran was a second-class petty officer shipfitter (metal, SFM) stationed on board the USS Bryce Canyon (AD-36) (active duty January 1966-October 1969); evaluations showed assignment to the shipfitting shop with duties including welding, silver brazing, plumbing, pipe fitting, and sheet-metal fabrication and repairs. Buddy statements from sailors who worked with him 'attest to their constant exposure to asbestos dust, fumes, and other asbestos materials, and their use of asbestos blankets, welding gloves, and grindings discs.' The Board recited 'Internet research reveals that the USS Bryce Canyon was associated with asbestos exposure. It is therefore conceded that the veteran was exposed to asbestos,' then found as fact that his diagnosed asbestosis 'is the result of asbestos exposure during active service' and granted service connection - resolving conflicting medical evidence (a 30+ year post-service civilian exposure history) in the veteran's favor.

   Limitations

   Adjudicated administrative decision (most final stage located for this hull): the exposure concession is hull-specific via duty assignment (shipfitting shop aboard this vessel) but rests on personnel records, evaluations, buddy statements, and 'internet research' - not on any hull material survey or sampling. The Board conceded exposure and granted service connection; a VA examiner had attributed disease to 30+ years of post-service civilian exposure, so nexus was contested even though the aboard-ship exposure concession itself was not. Does not establish quantity, condition, or that any specific product aboard contained asbestos.

   Finding

   Federal asbestos personal-injury record names this hull. Charles Krik, a Navy boilerman/boilermaker 1954-1970, alleged exposure to asbestos from Owens-Illinois's Kaylo block insulation during 'Bryce Canyon (Repair ship) - 1958-1961': deposition testimony recited that he boarded the ship November 1958 and 'did all the insulation repair,' ordered insulation out of a standard Navy supply catalog, performed about one firebox brickwork job every two months aboard, and that Kaylo was the standard Navy brickwork insulation (used on fireboxes, steam drums, mud drums); defendant's own 1983 discovery responses put Kaylo at 13%-25% asbestos and manufacturing end 30 April 1958. The court denied Owens-Illinois's motion for summary judgment (product-identification/causation) and its 'sham affidavit' motion to strike, holding a reasonable jury could conclude exposure to Kaylo was a 'substantial factor' in the illness and that defendant-made Kaylo reasonably could have been aboard ships until at least late 1959. Maritime law held applicable.

    Finding type

    litigation_product_id

    Finding

    Federal asbestos personal-injury record names this hull with product identification. Plaintiffs alleged Michael R. Marcus developed mesothelioma from asbestos-containing products worked on during Navy service; the order recites his service as boiler technician/boiler repairman aboard USS Bryce Canyon June 1975-August 1978 (among five named ships) and that 'while posted on the USS Bryce Canyon, Mr. Marcus worked on other naval vessels beyond those named.' For product ID: Velan acknowledged it 'did supply valve or steam traps for installation in four of the ships that Mr. Marcus recalled by name' - the opinion parenthetically lists USS Bryce Canyon among them; Velan's corporate representative conceded 'any valves sold by Velan prior to 1992 to the navy contained asbestos gaskets and packings' and steam traps sold to the Navy before 1984 'had an asbestos gasket'; the court DENIED Velan's summary-judgment motion on that record. Separately, Cleaver Brooks asserted the propulsion boilers in USS Bryce Canyon and USS Kitty Hawk 'were manufactured by Foster Wheeler Corporation' (the point was not rebutted on this record). Summary-judgment motions resolved in mixed grant/deny across ~15 defendants; the case then terminated via stipulated dismissals with prejudice (e.g., Armstrong International, order of 11 September 2024 on the public docket).

    VA Board of Veterans' Appeals decision names this hull in the service history of an asbestos-exposure service-connection claim: the veteran (active duty July 1958-July 1986) served aboard USS BRYCE CANYON (AD-36) between September 1968 and July 1971 (among USS Mahan, Duncan, and Oklahoma City); he claimed a disability caused by asbestos exposure 'on ships during his nearly 30-year career.' The Board found no claims-file records documenting in-service asbestos exposure and no current lung disability, and REMANDED for development (VA examination) rather than adjudicating exposure.

The Records Research Center reviewed the 1966-1967 USS Bryce Canyon (AD-36) command histories and deck logs for his two documented assignment periods aboard (September 8-October 4, 1966 and October 25, 1966-July 1, 1967) in the herbicide-agent context.

    Finding

    Source discrepancies resolved or flagged: (a) Keel date - ShipScribe's contract table prints 5 Jul 45, secondary compilations (Wikipedia, hullnumber.com, NavalCoverMuseum) print 7 July 1945, and NavSource lists 'date unknown'; ShipScribe (closest to contract records) is carried in laid_down and the conflict is flagged, not resolved. (b) Class heading - the HyperWar/ibiblio photo index heads the AD-36 ship page 'Hamul class,' while DANFS ('cl. Shenandoah'), NavSource, and ShipScribe all class her Shenandoah (the AD-26 class was designed 'similar to HAMUL (AD-20)' per ShipScribe); Shenandoah adopted. (c) Name collision - MARAD ShipHistory Detail/613 'BRYCE CANYON' is a 1944 Kaiser (Swan Island) T2-SE-A1 tanker, official no. 246965, not this Navy hull. (d) Class roster - ShipScribe/DANFS-type rosters place completed sisters at AD-26, 27, 28, 29, 31, 36 with AD-30, 33, 35 cancelled; Grand Canyon reclassified AR-28 in 1971 while this hull remained AD-36 throughout.

    Limitations

    Publication-level discrepancy flagging among the cited sources; the keel-date conflict is carried rather than resolved (no primary contract record consulted). Does not materially affect identity or service timeline. No asbestos content in any of these sources.
