Legal-Technical Case Correlation Summary
Aviation Incident Discovery & Telemetry Framework
The Interplay of Flight Data and Legal Liability
Modern commercial aviation litigation requires immediate correlation between three distinct streams of discovery before physical spoliation or digital overwriting occurs:
1. Telemetry / FDR (Flight Data Recorder): Over 1,000 continuous digital parameters including control column deflection, engine N1/N2 trim, pitch/roll, autopilot status, and angle of attack (AOA) sensor outputs.
2. CVR (Cockpit Voice Recorder): 2-hour loop recording cockpit micro-audio, crew alerts, GPWS alarms, and manual switch clicks.
3. Manufacturer Service Bulletins: Prior FAA Airworthiness Directives (ADs) and OEM non-mandatory service letters identifying known software bugs, actuator icing, or pitot probe calibration drifts.
Cross-Border Jurisdiction & Forum Non Conveniens
When foreign air carrier flights suffer incidents involving American-manufactured aircraft (such as Boeing), plaintiffs face complex procedural hurdles:
Forum Non Conveniens: Manufacturers frequently move to dismiss claims filed in U.S. federal courts, asserting that foreign courts (carrier home state or crash jurisdiction) provide a more adequate forum.
Overcoming Dismissal: Plaintiffs must establish that the root cause arises from design decisions, component sourcing, flight control computer coding, or failure-to-warn conducted within the United States.
Montreal Convention Art. 28: Establishes strict liability thresholds for carriers up to 128,821 SDRs (approx $175,000 USD) with unlimited carrier liability unless the airline proves zero negligence.
What specific black box data files are requested during NTSB / FAA / EASA Annex 13 investigations?
Under ICAO Annex 13, the state of occurrence conducts the official technical safety probe. Attorneys and independent consultants rely on raw ARINC 717 and ARINC 767 digital stream dumps decoded via sensor conversion equations. This includes Pitot-Static pressure delta, inertial reference system (ADIRU) drift rates, stabilizer jackscrew position, and engine FADEC fault logs.
How does local evidence processing safeguard sensitive investigation records?
Litigation preparation requires strict confidentiality protections under attorney-client privilege and work-product doctrines (FRCP Rule 26(b)(3)). This tool processes all flight sensor timelines and discovery requests locally within your client browser session, generating offline exports without passing proprietary data to third-party servers.
Informational limits and expert requirements
This workbench is an organizational and analytical framework for investigative correlation and educational demonstration. It does not provide legal advice, formal expert witness testimony, or certified flight recreation. Aviation claims require licensed aviation counsel admitted in relevant jurisdictions and accredited aeronautical accident reconstruction engineers.
