Overview
• Explanation of term “FADEC”• New regulatory guidance: Notice N 8000.331
– New definition of “Complex” Airplane!
• Multi-Engine piston aircraft with FADEC• Practical Tests: Single-Engine ops• Your Questions

What is “FADEC”?
F – Full A – Authority D – Digital E – Engine C – Control
In other words:
Computerized engine control!

4FADEC & the CFIMay 5, 2007
FAA Notice N 8000.331• New regulatory guidance, eff. Nov 2006• Redefines “Complex Airplane” two ways
– If FADEC installed:
Retractable Landing Gear
+ Flaps
+ FADEC
= Complex Airplane!– If FADEC not installed:
• Use conventional definition!
• Most significance for light piston twins

New Piston Twin with FADEC• Diamond Aircraft
DA42 “Twin Star”
– TAA– Diesel engines (typ)
• LE critical!– FADEC– G1000 Avionics– Carbon fiber– Training role

DA42 trivia:• Chandelles, Lazy-8’s approved!
– FSDO does not recommend these maneuvers.
• Grass runways approved!• “Dynamic” stalls not approved• Vlo (extension & extended) = Vne = 194• Powerplant instrumentation:
– Percent load, 0 – 100% and – RPM
• Loss of electrical power to FADEC unit(s)• Again: Critical Left engine!

9FADEC & the CFIMay 5, 2007
FADEC Single-engine operations
• Troubleshooting steps are minimal– Fewer things to check: focus is back on flying– ECU doing most of the work. New Term: “ECU Swap”– Autofeather provision
• Zero-Thrust settings– Not published (yet) for DA42
Federal AviationAdministration
10FADEC & the CFIMay 5, 2007
Intentional feathering
• Retard thrust• Eng M. Sw. Off
Prop feathers!
• Restart:– Reverse steps!– Diesels use compression for ignition!
