When structural life is uncertain, readiness is at risk. TDA provides independent airworthiness engineering services based on real-world operational data.
Aircraft Structural Analysis & Fatigue Life Assessment
Understand structural risk. Extend service life responsibly.
We deliver independent structural integrity analysis informed by mission profiles, operational spectra, and validated stress modeling.
Capabilities include:
- Aeroelastic external loads modeling and simulation
- Mission spectrum development and sequencing
- Gust and turbulence environment modeling
- Classical stress analysis and finite element modeling (FEM)
- Fatigue and damage tolerance assessment
- Crack growth and durability evaluation
- Structural modification analysis and flight clearance substantiation
- Failure investigation and structural risk assessment
We support fixed-wing, rotary-wing, unmanned aircraft systems (UAS), special mission, and intelligence, surveillance, and reconnaissance (ISR) aircraft programs with disciplined engineering aligned with established airworthiness and ASIP frameworks.
Working with USN, USMC, USAF, FMS Partners (Australia, Denmark, Japan),
and OEMs including Boeing, Bell, Sikorsky/Lockheed Martin, Parker Hannifin, Moog, and Yulista.
*The U.S. Navy estimates approximately $121M in savings for the H-60 (2018), plus over $125M in NAE savings each year based on incorporation of other rotary- and fixed-wing aircraft.
Fleet Readiness & Maintenance Optimization
See how today’s flying impacts tomorrow’s availability.
We deliver fleet-level life-cycle modeling that quantifies structural degradation and informs inspection planning, sustainment strategy, and retirement decisions.
We support programs through:
Fatigue Life Expended (FLE) tracking
Total Life Index (TLI) methodology
Probability of Failure (PoF) modeling
- Utilization rate analysis and mission sensitivity studies
- Inventory forecasting and retirement projections
- Environmental and mission mix impact assessment
The result: quantitative life-cycle visibility, reduced uncertainty, and improved fleet availability.
Data Analytics & Engineering Decision Support
Turn high-volume operational data into validated engineering outputs.
We process, validate, and reduce operational data into fatigue spectra, exceedance metrics, and life-cycle projections suitable for engineering decision-making.
We analyze:
Flight Data Recorder (FDR) downloads
Structural Health Monitoring (SHM) inputs
Regime recognition and usage classification data
- Aircraft health monitoring system outputs
- Logbook and configuration records
- Flight test strain and loads data
Our analytical workflows ensure that operational use directly informs fatigue modeling, inspection planning, and life-extension strategies.
training and knowledge transfer
Strengthen engineering judgment.
We provide short courses and on-site instruction led by practicing engineers with direct program experience supporting defense and government aviation.
Fleet tracking and decision platforms
into life-cycle visibility.
We develop and support purpose-built platforms that integrate validated loads modeling, fatigue assessment, and configuration tracking into program-level decision tools.
