Liebherr-Aerospace Delivers
First Components for A350 XWB Flap System

A Supplier to Airbus from the Very Beginning

Recently, the first ship set of the load-
sensing drive strut for the A350 XWB flap
system, developed and manufactured by
Liebherr-Aerospace Lindenberg GmbH
(Germany), was delivered to the Airbus
system test bench in Bremen (Germany).
The set consists of a strut for the flap sta-
tions 1 and 4 and the associated harness-
es. This mechanical-electronic compo-
nent is installed four times in each aircraft.

The load-sensing drive struts signal to
the high-lift controller if there are unac-
ceptably high loads between the actu-
ation system and the flaps, which may
occur in case of certain faults. The con-
troller then causes the flap system to en-
ter the so called fail-safe mode, by turn-
ing it off. Airbus simulates one wing side
of the aircraft on the system test bench.

From the earliest days of Airbus in
1969, Liebherr-Aerospace has been
on board of this unparalleled Euro-
pean aviation initiative. The compa-
ny has equipped the Airbus A300,
the A310, the A320 family, the
A330 / A340 and the A380 – in short,
all families of Airbus aircraft – with

components and systems in the
fields of flight control / actuation, air
management and landing gear. The
A350 XWB will soon be supplied too.
In the course of their long-standing
business relationship, Airbus has
awarded many prizes to Liebherr-
Aero space. The latest recognition

was the Bronze Award 2011, which
Liebherr-Aerospace Toulouse SAS
received for its improved perfor-
mance despite the complete loss
of the Liebherr-Aerospace facility in
Guaratinguetá (Brazil) during a cata-
strophic fire.

was successfully put into operation
with a load-sensing drive strut to con-
duct the usual tests for technical perfor-
mance, endurance, fatigue, vibration and
environmental sustainability.
