Product Description
The Pratt & Whitney JT8D low-bypass turbofan was one of the most widely produced commercial jet engines of the 1960s-1980s, powering the Boeing 727, Boeing 737-100 and 737-200, and the McDonnell Douglas DC-9 series. Plaintiffs allege in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that the JT8D engine build package was assembled with asbestos-composite exhaust-flange and combustor gaskets, asbestos-fabric combustor-liner and hot-section wrap insulation, and asbestos-block lagging in the hot section. Plaintiffs allege these materials were selected for their high-temperature sealing and thermal-insulation performance in the turbine and exhaust modules of the engine.
Workers Exposed
Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that occupational exposure to alleged JT8D asbestos components occurred among:
- Airline engine-shop mechanics performing heavy overhaul and hot-section refurbishment
- Aircraft engine test-cell operators running post-overhaul acceptance tests
- Airline line-maintenance engine mechanics performing on-wing gasket and duct service
- U.S. Naval Air Systems Command engine mechanics working on JT8D-derived TF33 and related powerplants
- Engine-shop combustor and turbine disassembly technicians
Alleged exposure pathways included dust generated during gasket scraping from combustor and exhaust flanges, disturbance of combustor-liner and hot-section wrap insulation during teardown, and removal of hot-section block lagging during engine reset for overhaul.
