General Description
General:
The Liberty XL2 airplane is manufactured by
Liberty Aerospace, Inc.
1383 General Aviation Drive
Melbourne, Florida, USA, 32935
1-800-759-5953
and is approved in the normal airworthiness category.
The XL2 may be operated under DAY or NIGHT VFR conditions depending on
installed standard and optional equipment. IFR certification is pending.
Description:
The Liberty XL2 airplane is a low-wing two-place aircraft with tricycle landing gear.
Its central structural element is a welded steel tubing frame or “chassis” which has
the following components attached:
•Engine and Propeller
•Wings (conventional aluminum construction)
•Main landing gear (aluminum construction)
•Nose landing gear (steel construction)
•Fuselage (composite construction), including;
•Aft fuselage with vertical fin (composite construction)
•Rudder and stabilators (aluminum construction)
•Center fuselage including crew/passenger cabin, fuel tank, and baggage
compartment
•Engine cowlings.
The wings are bonded aluminum semimonocoque structures, and are secured to the
chassis by means of heavy steel pins in attach fittings. With the wing or wings
removed the fuselage remains supported by the landing gear. The removable
aluminum horizontal tail is a stabilator type in which the entire unit moves to change
pitch on the aircraft. The only movable surfaces on the horizontal tail are the anti-
servo tabs which are used for both pitch trim and anti-servo functions.
The composite vertical fin is integrated into the fuselage structure; the rudder is an
aluminum structure.
Ailerons and stabilators are operated by pushrods from cockpit control sticks.

The rudder is operated by pushrods attached to adjustable cockpit rudder pedal
assemblies. Aluminum trailing edge flaps are electrically operated.
The XL2 is powered by an air-cooled Teledyne Continental Motors IOF-240-B four
cylinder, horizontally opposed, fuel injected engine. The engine is rated at 125
continuous SAE horsepower at 2800 RPM. The engine is equipped with a Full
Authority Digital Engine Control (FADEC) system to control ignition timing and fuel
mixture without pilot intervention. Fuel is supplied from a single 28 gallon capacity
aluminum tank. It is installed in the fuselage between the pilot/passenger seatbacks
and the baggage compartment. The propeller is fixed pitch, constructed of wood
and fiberglass made by Sensenich p/n: W69EK7 63G.
