The Aviation Machinist’s Mate (AD) rating maintained, repaired, and tested aircraft piston engines, turboprop engines, and jet engines; operated aircraft engine test cells; and performed powerplant maintenance in aircraft hangars and engine shops. The publicly filed asbestos litigation record documents AD exposure from asbestos-containing insulation in aircraft engines, asbestos gaskets and seals used in jet engine maintenance, asbestos-containing construction materials in maintenance hangars, and the Navy’s documented knowledge that aircraft engines contained asbestos-containing components through the 1970s.

Documented Exposure Sources

Aircraft Engine Asbestos — Direct Documentation

Jet Engine Maintenance — Asbestos Gaskets and Seals

Aircraft gas turbine engines used asbestos-containing gaskets, seals, and insulation blankets throughout the relevant period. ADs who performed turbine section removals, compressor overhauls, combustor liner replacements, and exhaust system repairs worked directly with asbestos-containing engine components that shed fibers when disturbed, cut, or ground.

Aircraft Maintenance Hangars — Construction Materials

The carrier hangar bay overhead — where ADs worked on aircraft suspended from maintenance platforms — was fireproofed with sprayed asbestos on structural steel through the 1970s, creating overhead asbestos exposure during aircraft maintenance operations.

Rating Specialties

The AD rating was divided into specialties tied to powerplant type:

  • ADJ — jet engine specialists; maintained J57, J79, TF30, F404, and other naval gas turbines; highest asbestos exposure from engine disassembly
  • ADE — reciprocating engine specialists; maintained R-1820, R-2800, and R-3350 piston engines; asbestos gaskets were standard in piston engine overhauls
  • ADR — airframe and powerplant combination (later split out); broader aircraft maintenance with equivalent asbestos exposure

All AD specialties worked in the same maintenance hangar and engine shop environments with asbestos-containing construction materials.

The Aviation Machinist’s Mate rating qualifies for VA service connection under VA asbestos-claim guidance based on documented asbestos in aircraft engines, asbestos-containing gaskets and seals in engine maintenance, and asbestos-containing construction materials in the maintenance hangars and engine shops where ADs worked. The corpus directly documents asbestos in aircraft engines — the AD’s primary maintenance item — appearing in formal litigation records.

Key documents for an AD claim:

  • DD-214 Block 11 — primary specialty showing AD rate and subspecialty (ADJ, ADE, ADR)
  • Ship assignments — carrier duty stations documenting hangar bay aircraft maintenance
  • Shore duty — NAS maintenance department assignments documenting engine shop and hangar work
  • Diagnosis — mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease

Civil claims may run against manufacturers of asbestos-containing aircraft engine components, asbestos gaskets and seals used in engine overhaul, and asbestos-containing floor tile and construction materials in Navy aviation maintenance facilities.
