Engine
The airplane is powered by a Lycoming Engines IO-390-C3B6,
four-cylinder, normally aspirated, fuel-injected engine producing 215 HP
at 2,700 RPM. The engine has a 2200-hour Time Between Overhaul (TBO),
and may be eligible for an extension as defined in Lycoming Service
Instruction No. 1009. Dual, conventional magnetos provide ignition.
Starting performance is improved by the addition of a SlickSTART™
magneto start booster.
The engine is attached to the firewall by a four-point steel mount structure.
The firewall attach points are structurally reinforced with gusset-type
attachments that transfer thrust and bending loads into the fuselage shell.
