TM-061 | King Air B300/B300C Fuel Systems & Troubleshooting

Storage

Main groups, nacelles and auxiliary cells

Supply

Normal boost, standby and crossfeed

Indication

Capacitance quantity and independent low-level sensing
Understand standard B300/B300C fuel architecture: main and auxiliary storage, gravity feed, venting, boost, jet-pump transfer, crossfeed and quantity sensing. Includes a 30-page handbook, interactive flow and quantity workbench, 12 diagnostic cases and a 40-question final.

What's included?

  • 10 focused lessons
  • Completion certificate
  • 40-question final
  • 12 guided fault cases
  • 30-page handbook

Understand the connected system

Trace each main group to its nacelle, engine-feed and auxiliary-transfer paths. Separate crossfeed from tank-to-tank transfer, connect venting to replenishment, and distinguish capacitance quantity from independent low-level sensing. Covers the standard installation; ER/CER equipment requires its own applicable instructions.

Practise defensible fault isolation

Work through six flow exercises, 12 guided cases and an independent review. Complete the lab and pass the 40-question final at 80% to earn a completion certificate. Use current aircraft-effective maintenance instructions for practical work.
