KEY RESPONSIBILITIES
Stress Analysis & Structural Substantiation
• Perform linear and non-linear FEA using MSC Nastran/Patran, HYPERMESH, ANSYS, or equivalent FEM tools for aircraft interior structural components.
• Conduct static, energetic (crash/HIC) for seating systems, passenger service units (PSUs), cabin panels, galleys, and monuments.
• Develop and maintain FE models for primary and secondary interior structures including composite and metallic assemblies.
• Execute hand calculations to validate FEA results and provide independent verification of structural margins.
• Perform stress substantiation per applicable FAA/EASA airworthiness regulations (FAR 25, CS-25) and OEM structural design requirements.
Product Scope — Interior Structures
• Seating Systems: Economy, business, and first-class seats including track attachment, lug analysis, seat pan, armrest, and recline mechanisms.
• Cabin Panels: Sidewall, ceiling, floor panels — including attachment interface, pressure, and inertia load analysis.
• Galley Structures: Full-size, quarter,



and half-galley stress verification including trolley loads, utility connections, and monument interfaces.
• Monuments: Lavatories, crew rest modules, partition walls, dividers — structural adequacy under static and energetic load conditions.
• Overhead Storage Bins (OSBs): Latching loads, hinge analysis, filling load cases, and door stop analysis.
Composite Structures
• Conduct composite laminate analysis — ply-by-ply stress, first-ply failure, progressive failure, and delamination assessment.
• Apply classical lamination theory (CLT) and failure criteria (Tsai-Wu, Tsai-Hill, Maximum Strain).
• Perform bonded joint and fastened joint analysis for composite-to-composite and composite-to-metallic interfaces.
• Collaborate with Materials & Process (M&P;) team to define lay-up, fiber orientation, and repair schemes.
Certification & Documentation
• Prepare stress reports and substantiation packages in compliance with OEM (Boeing, Airbu
