TRACE DETECTION, WARNING AND PORTABLE EXTINGUISHER EVIDENCE

ATA 26 • Caravan

TM-034 | Caravan Fire Detection & Extinguisher Maintenance

Distributed architecture

Three engine detection sections and connected warning paths

Detection & inspection

Separate sensing, annunciation, CAS and portable equipment

Diagnostic evidence

Compare loop condition, warning response and bottle evidence
Cessna 208/208B three-section engine fire detection and the described portable Halon 1211 installation. Distinguishes annunciator, CAS and later NXi CMC effectivity; modified detection systems or alternative extinguishers require their applicable data. Includes a 26-page handbook, six prediction exercises, eight diagnostic cases and a 40-question final.

What's included?

  • 8 focused lessons
  • Completion certificate
  • 40-question final
  • 8 guided fault cases
  • 26-page handbook

Understand the connected system

Understand how three engine fire-detection sections, their electrical paths and cockpit warnings work together. Distinguish annunciator, CAS and later NXi CMC effectivity; relate loop condition and installation geometry to fault evidence. Portable Halon 1211 equipment has its own inspection, weight and serviceability evidence.

Practise defensible fault isolation

Practise six prediction-and-Apply exercises, eight two-stage fault cases, loop-radius and bottle-weight comparisons and twelve independent decisions. Complete the lab and pass a separate 40-question final at 80%.
