What Is a Structural Repair Manual (SRM) in Aviation?
Learn what a Structural Repair Manual (SRM) is, how it defines repair limits, and when DER or OEM approval is required in aviation MRO.
Certified Repairs
Diverse Aero Services (DAS) is a Miami-based FAA & EASA Part 145 structural MRO specializing in heavy airframe repairs, large-component overhauls, and DER-engineered solutions that reduce downtime and material spend.
We take an engineering-led approach to restore structural integrity while preserving serviceable material, compressing turnaround time, and lowering supply-chain risk — backed by advanced NDT, certified engineering, and 24/7 AOG support that keeps aircraft flying.
Trusted by airlines, cargo operators, and manufacturers worldwide.
FAA & EASA Part 145 is our baseline — not our ceiling. Through engineering-led decision-making, disciplined process control, and data-driven triage, we shorten TAT, strengthen long-term structural performance, and keep audits clean across every project.
Built-in compliance from intake to release, with end-to-end documentation aligned to operator, lessor, and regulatory expectations.
Our processes integrate approved data, structured work cards, calibrated tooling, and full traceability — so every repair is defensible in service and audit-ready on paper.
From complex fuselage sections to primary wing-structure assemblies, including frames, skins, stringers, spars, ribs, and critical load paths.
We combine advanced NDT, certified engineering, and controlled repair environments to restore structural integrity while minimizing unnecessary material replacement.
A proven track record across diverse aircraft platforms — commercial and cargo.
Our experience spans legacy fleets and next-generation aircraft, allowing us to balance speed, compliance, and durability in every structural repair program.
A strategic location for rapid response, efficient logistics, and access to major air routes.
From 24/7 AOG deployments to coordinated shop repairs, our Miami hub enables faster mobilization, shorter transit times, and tighter control over schedule risk.
From complex structural restorations to precision overhauls, DAS delivers certified MRO solutions designed for the most demanding airframe challenges.
For decades, Diverse Aero Services (DAS) has been a trusted partner for complex structural maintenance and large-component overhauls across commercial and cargo fleets. From major airframe repairs to full landing-gear restorations, our FAA & EASA Part 145 team delivers not just repairs, but engineered outcomes — balancing safety, compliance, cost control, and turnaround time (TAT).
From our state-of-the-art Miami facility, we serve operators worldwide with solutions designed for durability, regulatory rigor, and operational predictability. By integrating advanced NDT, DER-supported engineering pathways, and 24/7 AOG response, DAS enables operators to move from reactive maintenance to proactive, performance-driven structural MRO — reducing risk, compressing downtime, and protecting fleet value.
Partner with DAS for certified structural MRO solutions trusted by operators worldwide.
DAS provides FAA & EASA Part 145 structural MRO for major airframe structures, including fuselage and wing sections, nacelles (fan/inlet/core cowls, thrust reversers), radomes, flight controls (flaps, slats, rudders, ailerons), and floor/structural panels. We work across composites and sheet metal, combining advanced NDT, engineering, and certified repair pathways to restore airworthiness with minimal TAT.
Yes. DAS operates as a fully certified FAA & EASA Part 145 Repair Station, with controlled processes, approved data (SRM/OEM/DER), and complete traceability from induction to Return-to-Service. Our systems are aligned with operator and lessor requirements to keep audits clean and reduce compliance risk.
Yes. DAS delivers 24/7 AOG Miami structural response, deploying certified teams with mobile tooling, on-site NDT, and real-time engineering support. Our goal is to stabilize the aircraft quickly, define the safest repair path, and minimize operational downtime.
Yes — where eligible. DAS provides DER repair solutions for oversized, complex, or “replace-only” structural damage, creating compliant alternatives that reduce lead time and material cost. These FAA-approved engineering pathways maintain full regulatory integrity and documentation.
We perform composite repair using Qualified Composite Repairs (QCR) for minor damage, bonded repairs under controlled heat/pressure, and bolted repairs for larger restorations. All work follows validated cure profiles, environmental controls, and documented process records.
Yes. DAS performs precision sheet-metal repair, including forming, blending, and riveted/bolted restorations on metallic and hybrid structures. All repairs are finished to OEM-equivalent standards and supported by approved data and inspection records.
Yes. DAS uses controlled downdraft paint rooms to apply OEM-equivalent coatings and corrosion protection. This ensures structural durability, environmental resistance, and regulatory compliance after repair.
