Evidence before adjustment

Separate physical security, warning response, support and structure
Understand how Caravan doors transmit handle movement, carry loads and report latch conditions. Includes a 25-page handbook, eight connected lessons, six prediction exercises, eight two-stage fault cases and a 40-question final. Identify the actual door, serial and optional installation before selecting the applicable task.

What's included?

  • 8 focused lessons
  • Completion certificate
  • 40-question final

Understand the connected system

Trace handles, spindles, bellcranks, pushrods and latch pins. Explain upper-door gas springs, lower-door damping and restraint cables. Distinguish conventional DOOR WARNING, identified NXi CMC inputs and optional roll-up drive. Connect geometry, structural inspections and restoration to complete effective tasks.

Practice defensible fault isolation

Complete six prediction-and-Apply exercises, eight two-stage cases, a required door-geometry evidence bench and twelve independent decisions. Complete all 24 lab requirements and pass the separate 40-question final at 80%. Based on supplied Cessna D2078 Chapter 52, with the May 2024 chapter edition identified; aircraft-effective tasks govern physical work.
