  • Page 27: Section 10 - Description Of Systems

    SECTION 10 - DESCRIPTION OF SYSTEMS The C42 is a simple aircraft whose structures and systems are readily inspected and maintained. However, since some of its systems differ from those found on conventional aircraft; this section should be studied before dismantling, repair or inspection.
  • Page 28 Fuel Capacity The C42 has either a 50 litre or 65 litre fuel tank as standard. Both fuel tanks are inter-connectable so fitting an additional tank doubles the capacity to 100 litres or 130 litres. This capacity is placarded next to the filler cap.
