The Industry Challenge
Aerospace and Defense operators are under increasing pressure to sustain aging fleets amid supply chain disruptions, skilled labor shortages, regulatory complexity, and rising MRO demand. Regional supply constraints, long lead times, and limited engineering capacity often slow repairs, delay returns to service, and drive up lifecycle costs.
Why It Matters
Aftermarket performance directly impacts mission readiness, safety, and cost control. When repair engineering, service documentation, and fleet data are disconnected, organizations face longer downtimes, repeated failures, and missed opportunities to improve reliability. In mission-critical environments, sustainment is not just maintenance—it is a strategic capability.
Our Approach
QDSS applies an engineering-led, data-driven approach to aftermarket services. We integrate repair engineering, service engineering, fleet data analysis, and root cause corrective action into a unified sustainment model. Our teams work alongside OEMs, operators, and MROs to resolve in-service issues, improve product reliability, and extend asset life—while maintaining compliance and traceability.
We focus on standardization, simplification, and speed, enabling faster decisions, repeatable repairs, and continuous improvement across the fleet.

Our Disciplines
Repair Engineering
Engineering ownership of repair design, analysis, and readiness. We develop repair schemes, support deviation approvals, manage vendor qualification, and enable rapid disposition to return assets to service safely and efficiently.
Includes:
- Repair design and structural analysis
- Repair readiness level processes
- Tooling design and management
- Vendor management and qualification
- Deviation and disposition support
Product Improvement Initiatives
Turning in-service experience into measurable product improvement. We analyze operational data to identify reliability gaps, drive cost-reduction initiatives, and improve maintainability across the fleet.
Includes:
- Proactive and condition-based maintenance strategies
- Defect investigation and resolution
- Productivity and cost-reduction improvements
- Life-extension initiatives
- Model-Based Systems Engineering (MBSE) support
Root Cause Corrective Action (RCCA)
Structured problem-solving to prevent recurrence. We lead root cause investigations for in-service events, ensuring containment, corrective action, and verification are executed with rigor and traceability.
Includes:
- Team-oriented problem solving (TOPS8D)
- Failure Mode and Effects Analysis (FMEA)
- Containment and corrective action execution
- Verification and validation
- Quality escape management
Service Engineering
Sustaining products in operation through accurate, actionable service content. Our teams resolve field issues, manage service bulletins, and ensure maintenance documentation reflects real-world operating conditions.
Includes:
- Service bulletin development and execution
- Field issue investigation and resolution
- Maintenance publications and service documents
- Customer-fielded hardware management
- Data reduction and analysis
Product Fleet Data Management & Analysis
Data-driven insights that inform sustainment decisions. We consolidate fleet data to support health monitoring, maintenance planning, and lifecycle optimization.
Includes:
- Fleet health monitoring
- Maintenance planning and optimization
- Earned Value Management (EVM)
- System-level analysis and reporting
- Probabilistic life analysis
- Procedure documentation and validation
