Structural analysis built for certification. Delivered with the rigor your program demands.
Palomar Aerospace specializes in fatigue and damage tolerance analysis for metallic structure, with deep expertise in pressurized fuselage applications across commercial aircraft ranging from regional to wide-body platforms. Crack growth and residual strength evaluations are performed using industry-standard tools including AFGROW and NASGRO, applied against the most conservative load conditions your program demands. Deliverables are structured to produce Instructions for Continued Airworthiness (ICA) ready for DER approval under FAA Form 8110-3. We also provide Alternate Means of Compliance (AMOC) support — including technical substantiation and FAA correspondence — for structures subject to Airworthiness Directive requirements.
Structural analysis at Palomar Aerospace spans the full spectrum — from classical hand calculations to complex finite element modeling. Our methods include closed-form analytical approaches as well as FEM solutions using industry-standard platforms including PATRAN, HYPERMESH, FEMAP, APEX, and StressCheck, with analysis workflows that incorporate automation to maximize efficiency and consistency. Where internal loads models are not available, we apply reverse engineering methods to develop the load inputs your analysis requires. Primary strength is fuselage structure, but our experience extends across all major airframe structural areas. Deliverables are documentation-complete compliance reports structured for DER review and FAA Form 8110-3 approval.
When in-service damage falls outside the Structural Repair Manual, operators and MROs need more than analysis — they need a repair designed fast and substantiated to certification standards. Palomar Aerospace provides end-to-end repair disposition: from rapid damage assessment and repair concept development to full static and fatigue substantiation. Our experience spans all major airframe structural areas with peak efficiency in fuselage structure, and includes AOG support for time-critical situations where schedule pressure is as real as the structural requirement. Deliverables are DER-ready compliance reports under FAA Form 8110-3 — giving operators and MROs a clear, approvable path forward.
Every deliverable Palomar Aerospace produces is built with one end goal — FAA Form 8110-3 approval. Our certification support experience spans large-scale Supplemental Type Certificates (STCs), special mission modifications including radome and antenna installations, and structural compliance under FAR Part 23 and FAR Part 25. We work closely with a network of DERs to shepherd analysis packages from first submittal to approval, with documentation structured to minimize revision cycles. For structures subject to Airworthiness Directives, we also provide Alternate Means of Compliance (AMOC) technical substantiation and FAA correspondence support — giving operators and MROs a compliant path forward without unnecessary program delays.
Palomar Aerospace was founded on a simple premise: that rigorous structural analysis, delivered efficiently and on time, should not require a large firm or an outsized budget. With over a decade of experience on commercial aircraft programs ranging from regional jets to wide-body platforms, we bring the technical depth of a major OEM with the responsiveness of a dedicated partner.
Our work spans fatigue and damage tolerance, structural stress analysis, repair disposition, and certification support — across FAR Part 23 and Part 25 programs, large STCs, and special mission modifications. Every engagement is led by a senior engineer from day one. No handoffs, no diluted oversight. Just sound engineering and deliverables built to be approved.
