Inspection of wires should concentrate on any areas where the wires come into physical
contact with other components. These areas may cause stress concentration and
mechanical wear. Some areas may need to be partially disassembled to fully inspect
wires. Kinks created during packing up, transport and storage should also be checked.
Any degradation of wires requires replacement. Check thimbles and stainless steel tangs
for deformation.
Control Cables
There is a single fine cord on the BioniX² wing, used to control the tension of the
CORSET configuration system. The fine cord of the CORSET runs through the hoist on
top of the keel, then through the pulley located on the hang point, then along the right
strut of the A-frame through two guides before winding itself around the cone-shaped
spool of the command lever. The system should be checked regularly to detect friction or
excessive wear. In cases of damage is visible on the protective sleeve of the fine cord, it
should be replaced. The replacement of the fine cord is in any case mandatory every 300
flight hours. This replacement is easy to perform by simply detaching the central batten
of the trailing edge, opening the zippers of the central neoprene junction up to the
kingpost, then pulling out the used cord and inserting a new one prepared by Air
Creation. To perform this operation, follow the instructions on paragraph 5.2.3 n° 18.
5.3.4 CORSET
The CORSET system consists of four main elements: the central battens which exert
tension on the sail, the hoist that controls the tension, the pulley on the hang point and the
command controls.
The central battens are slid in the pockets sewn into the upper surface of the sail. The
straps of the CORSET are wrapped around the battens in the openings made in the
pockets. The right back strap of the CORSET is blocked on the right batten by means of a
Parker screw to prevent the hoist from slipping forwards as it comes under tension. The
back ends of the central battens are inserted in the front near the king post.
A locking pin
blocks any rotational movement of the two parts. The front and rear parts are to be
inspected visually during periodic visits to find traces of wear, cracks or deformations
around the straps of the hoist and the restraining straps on the keel behind the king post
near the trailing edge. The general profile of the central battens is to be checked after
disassembly during major overhauls by means of the drawings provided.
The hoist consists of two blocks of pulleys linked to the central battens by straps and held
together by a PCV plate. This plate serves to protect the hoist from rubbing against the
tensioning cables. The pulleys, mounted on ball bearings, should be completely free to
turn without friction. Cleaning the pulleys is recommended during major overhauls to
eliminate dust that may have accumulated near the ball bearings.
The elbow of the hang point consists of two mounting brackets and a pulley. The pulley
should be totally free to turn without friction.
The command controls consist of a cone-shaped spool for winding and a handle that is
locked in position by a lug that fits in the holes of a stainless steel ring which is itself
secured to the body of the spool. The handle should naturally return to the locked
position after being pushed forward. If the return movement is insufficient, the
spring
I144917 should be replaced. The lug, Corset index D274030 and the blocking ring,
corset indexing plate D274025 can also be replaced in case of excessive usage.
No special maintenance of the CORSET system is necessary, except the periodic checks
described above.
