The 7-Day Window
The Geometry Gap

Every Aerospace
Borescope Looks Forward.
Biofilm Grows on the Wall.

A direct-view borescope traveling down a fuel line sees the lumen ahead — not the wall it is traveling along. Biofilm colonizes the inner wall surface. White-light optics cannot distinguish it from clean metal. 365 nm UV detects structural defects via FPI dye, not biofilm. No competitor offers the combination required: side-view optics + 405 nm UV fluorescence + aerospace tube diameter.

Biofilm reaches irreversible MIC corrosion threshold in 7 days. Standard inspection cycles are monthly or quarterly. The detection gap is structural — not a matter of technique or frequency.

Aerodetex holds four first-in-class capabilities no competitor matches: 405 nm biofilm-specific UV fluorescence, side-view tube wall inspection, dual-wavelength structural NDT + biofilm detection in one pass, and interchangeable probe diameters for aerospace fluid system access.

The Aerospace Industry Knows Biofilm Is a Problem.
It Does Not Have a Tool to Detect It.

Two methods dominate aerospace biofilm monitoring today. Both were designed for different purposes and applied to biofilm detection by default — not by design. Neither is capable of detecting early-stage biofilm in the 7-day window before MIC becomes irreversible.

Culture-Based Sampling

Collect fluid sample → ship to lab → incubate 24–72 hrs → count colonies

  • Detects planktonic (free-floating) organisms only
  • Biofilm-embedded organisms not captured in bulk fluid samples
  • Results arrive days after the critical 7-day MIC threshold
  • No uniform detection standard exists for aerospace fuel systems
Too slow. Too late.

White-Light Borescopy

Insert white-light probe → visually inspect internal surfaces

  • Early-stage biofilm (days 1–7) is optically transparent under white light
  • Cannot differentiate biofilm from fluid residue or staining
  • NASA confirmed: 100% of contaminated systems tested negative under white-light
  • Structural defects and biological contamination require separate inspection passes
Cannot see it.

UV Fluorescence (Videtex)

365 nm + 405 nm dual-wavelength probe → real-time autofluorescence imaging in-situ

  • Detects biofilm EPS matrix and fungal hyphae at day 1 — before MIC acceleration
  • 405 nm excites flavins (FAD, NADH) in biofilm without dye application
  • 365 nm detects structural defects per ASTM E1417 in the same pass
  • 3.9 mm lead probe fits standard aircraft access ports; full range 1.8–6.0 mm covers every aerospace fluid system geometry
Real-time. In-situ. Day one.

Three Systems. Three Failure Modes.
One Detection Platform.

Aerodetex addresses the three aerospace fluid system applications with the strongest combination of documented risk, regulatory pressure, and inspection accessibility — each with a distinct market entry path and value proposition.

MIC Prevention

Aircraft Fuel Tank Inspection

MIC accelerates by 2 orders of magnitude on day 7. Standard monthly inspection cycles miss the critical window.

UV fluorescence detects biofilm at the fuel-water interface on day one — before corrosion pits form in aluminum alloy tank panels.

Explore Use Case

No Standard Exists Today.
The Trajectory Is Clear.

The EPA found 100% of aircraft water systems non-compliant in 2004 and issued the Aircraft Drinking Water Rule in 2009 — but it addresses coliforms only, not biofilm. NASA has documented biofilm incidents in ISS life-support systems for over a decade and is actively funding biofilm mitigation research. The U.S. Air Force spends $1.6 billion annually on aviation corrosion.

The regulatory response to these pressures is a matter of when, not if. Organizations that establish UV fluorescence inspection capability before mandates arrive will be compliance-ready rather than compliance-reactive.

The Cost of Missing the 7-Day Window

A missed inspection cycle converts a zero-cost biofilm remediation event into a six-figure structural repair. The Videtex probe, integrated into a standard borescopic inspection workflow, adds minimal time and cost to an inspection that is already being performed.

Market Context: $90.85B Global Aircraft MRO (2024)

The global aircraft MRO market is projected to reach $120.96B by 2030 (CAGR 4.75%). Corrosion-related maintenance is a structurally recurring cost center that grows with fleet age and is disproportionately driven by undetected early-stage contamination. MIC is estimated to constitute 20% of total corrosion losses.

Built on Peer-Reviewed
Aerospace Research.

The Aerodetex detection protocol is grounded in published research from NASA NTRS, the Naval Research Laboratory, and peer-reviewed materials science literature. The 7-day MIC acceleration threshold, the 100% spacecraft water system contamination finding, and the failure modes of current detection methods are all documented in primary sources.

The aerospace industry is a specification-driven market. Third-party validation studies and co-authored case studies with MRO operators are the most credible marketing assets available. Aerodetex is actively seeking research partnerships.

Lu et al., Materials 2024 (PMID 39063815)

MIC corrosion current density in aluminum alloy fuel tanks increases by ~2 orders of magnitude on day 7. Recommended detection cycle: every 7 days.

NASA NTRS 2024 (ICES-2024-112)

Biofilm detected in 100% of inspected ISS ECLSS water systems. Real-time biofilm detection has never been performed on any spacecraft fluid system.

Naval Research Laboratory (ADA413907)

Aspergillus and Hormoconis resinae found in 100% of H-53 helicopter platforms. Contamination discovered only at depot-level maintenance — not during routine inspection.

EPA Aircraft Drinking Water Rule (2009)

100% of aircraft public water systems found non-compliant in 2004. Rule addresses coliforms only — biofilm remains unregulated in aircraft water systems.

The Same Platform That Protects Patients
Now Protects Aerospace Systems.

Aerodetex is built on the Videtex dual-wavelength UV fluorescence platform — the same technology used by Endodetex for medical endoscope channel inspection. The science is identical. The probe diameters are interchangeable. The biofilm detection principle works in any fluid system where contamination matters.
