Investigatory Pillars & Evidence Gap Audit

Flight Data & Voice Recorders (FDR/CVR) Secured & Downloaded

Solid-state flight recorders recovered by India AAIB; joint readout with UK AAIB accredited representatives per Annex 13 Ch. 5.

Pillar: Physical Recorders • Fidelity: Primary Evidence Tier
ATC Communications & Radar Echo Impounded & Synchronized

Continuous surface movement radar, localizer antenna logs, and approach frequencies (118.10 MHz) preserved with GPS timecode.

Pillar: Air Traffic Control • Coverage: Continuous T-30 to Incident
Technical Maintenance & Airworthiness Partial - Records Requested

Awaiting certified operator sign-offs, deferred defects (MEL), engine cyclic life tracking, and recent Service Bulletin compliance.

Action: Formal preservation notice served to carrier legal representative
Meteorological & Microburst Data Doppler Archive Awaiting

VAAH aerodrome METAR/SPECI reports integrated. High-resolution Terminal Doppler Weather Radar windshear alerts pending agency release.

Pillar: Environmental Context • Source: IMD Aviation Met Unit
Annex 13 Framework (Aircraft Accident and Incident Investigation):

Sole objective of Annex 13 is the prevention of future accidents; not the apportioning of blame or legal liability. The State of Occurrence (India AAIB) institutes the inquiry, granting full accreditation to the State of the Operator & Registry (UK AAIB) and State of Design/Manufacturer (US NTSB/Boeing/GE).

  • Accredited representative rights: inspect wreckage, receive FDR readouts, question witnesses.
  • Preliminary Report mandated within 30 days of the occurrence to ICAO and participants.
  • Factual information release restricted to investigator-in-charge (IIC) authorized bulletins.

Black Box & Telemetry Admissibility

Flight Data Recorders (FDR) log over 1,000 aerodynamic and system parameters. Cockpit Voice Recorders (CVR) capture 2 hours of 4-channel audio. Under Annex 13 Paragraph 5.12, CVR transcripts are protected and restricted solely to technical analysis unless judicial authorities establish an overriding public need.

  • FDR: Speed, pitch, roll, throttle resolver angle, rudder input.
  • CVR: Ambient cockpit sounds, crew callouts, system automated alerts.
  • Radar/ADS-B: Pressure altitude, ground track, transponder squawks.

Montreal Convention 1999 (MC99)

For international carriage between signatory states, MC99 establishes strict carrier liability under Article 17 for passenger injury or death arising from an in-flight or embarkation accident. Carrier defenses are tiered:

  • Tier 1: Up to 128,821 SDR (~$175,000 USD) strict liability regardless of carrier fault.
  • Tier 2: Unlimited damages unless the airline proves the damage was not caused by its negligence.
  • Jurisdiction options: Passenger domicile, carrier hub, ticket issue, or destination.

Evidentiary Preservation Duties

Following any major aviation occurrence, immediate formal preservation letters (spoliation notices) are typically submitted to safeguard fleet-wide inspection logs, pilot training duty-hour rosters, and weather radar raw files before automated deletion cycles execute.

  • Aircraft Technical Logbooks (Sector flight records & repairs).
  • Quick Access Recorder (QAR) high-density memory cards.
  • Ground handling, de-icing, and fuel load manifest records.
