1.0&Introduction&
This manual contains factory recommended procedures and instructions for ground handling,
inspection, servicing and maintaining the North Wing S-LSA aircraft. The procedures described
are to be used in conjunction with the appropriate Airworthiness Authority of the country of
registration. Any airworthiness requirement published by the national authority takes
precedence over this manual.
1.1#Skills#
Maintenance of any aircraft requires a skill level commensurate with the specific maintenance
task. This manual identifies the skill level for each maintenance task according to the
following industry standard certification levels:
Owner:
Tasks that can be expected to be completed by a responsible and skilled owner who holds a
pilot certificate but who has not received any specific authorized training. This includes all
items in Part 43 appendix A – Preventative maintenance.
LSA Repairman – Inspection:
Items that can be expected to be completed on an E-LSA by a responsible owner who holds an
FAA repairman certificate (light sport aircraft), with an inspection rating or equivalent.
Abbreviation: LR-I
LSA Repairman - Maintenance :
Items that can be expected to be completed on a S-LSA by a responsible individual who holds
a FAA repairman certificate (light sport aircraft) with a maintenance rating or equivalent from
an FAA approved 104 hour course on Weight Shift Control. Abbreviation: LR-M
A&P:
Items that can be expected to be completed by a responsible individual who holds a mechanic
certificate with airframe or power plant ratings, or both, or equivalent.
Task Specific:
Items that can be expected to be completed by a responsible individual who holds either a
mechanic certificate or a repairman certificate and has received task specific training to
perform the task. Abbreviation: TS
For those functions and tasks identified as suitable for an owner to perform, a sound
understanding of mechanical systems, and good experience with the necessary tools and
procedures is required. A lack of complete understanding of any task may render the aircraft
un-airworthy and unsafe. Assessment and judgment of the condition of each individual
component is required, which necessitates a sound understanding of the purpose of each
component in the system. If there are any doubts regarding the required and appropriate
maintenance, then the safety of the aircraft may be jeopardized in continuing with self

North&Wing&S,LSA&Maintenance&Manual&

maintenance. In this situation a North Wing-approved repair station should be contacted for
the correct procedures and or servicing.
All maintenance and repairs must be logged in the appropriate Airframe, Engine, Propeller, or
Wing log book and signed by the person who performed the repair. Logbook pages are given
in Appendix A of this manual. If additional pages are required, simply copy the required
pages and insert in this manual. Although it is recommended, it is not required to maintain
four separate log books as indicated above. However, any maintenance on any of the four
systems must be logged in a maintenance log book and signed by the person performing the
task.
1.2#Prohibited#Maintenance#and#Alterations#
This manual addresses only “Line” maintenance functions and tasks that can reasonably be
performed by a responsible and skilled as described above. It does not address any “Heavy”
maintenance tasks such as the removal of the engine cylinder heads, gear box, or electrical end
of the engine block. For all required maintenance on the Rotax 582, refer to the Rotax engine
manual provided with your North Wing S-LSA trike. For heavy repairs as mentioned above,
consult a factory trained and certified Repairman Maintenance technician for Rotax engines.
A list of Rotax repair stations can be found on-line, or contact your North Wing dealer.
Although “repairs” may be authorized for nearly all components, ”alterations” to the following
items beyond those specifically identified herein are strictly prohibited due to their critical
safety role:
o!airframe assembly
o!backframe
o!mast assembly
o!seat frame
o!root tube
o!steering assembly
o!pivot block assembly
o!wing ribs, cables, struts, crossbar, or control frame
o!bolt sizes or lengths

WARNING
THE INFORMATION IN THIS MANUAL NEEDS TO BE FOLLOWED, AND IT IS NOT
ACCEPTABLE TO MAKE CHANGES TO THE MATERIALS AND OR PHYSICAL
FEATURES OF THIS AIRCRAFT. IN PARTICULAR THE GRADES OF BOLTS THAT
HAVE BEEN UTILIZED IN THE MANUFACTURE OF THIS AIRCRAFT ARE CRITICAL
FOR ITS CONTINUING AIRWORTHINESS. NEVER REPLACE BOLTS WITH ANY
OTHER SIZE OR GRADE. GRADE 8 BOLTS ARE NOT INTERCHANGEABLE WITH
AIRCRAFT (AN) GRADE BOLTS. THE FATIGUE CHARACTERISTICS OF AIRCRAFT
GRADE BOLTS ARE SUPERIOR TO OTHER BOLTS AND ALLOW LONGER SAFE
SERVICE LIFE UNDER CYCLIC LOADS LIKE THOSE EXPERIENCED IN AIRCRAFT.
THE LENGTH OF BOLT IS IMPORTANT. IF A SHORTER BOLT IS USED THE THREAD
MAY ENCROACH ON THE LOAD BEARING AREA, WHICH INCREASES THE
STRESSES EXPERIENCED BY IT.
1.3#Tooling#and#Materials#
In general, all maintenance described herein is capable of being done with standard mechanics
tools. However, since the Rotax engine is built in Austria, a set of metric open end, box,
sockets, and hex wrenches may be needed. The only tools that might be considered somewhat
special or unusual needed for the maintenance described in this manual are the following:
•!Low range torque wrench capable of up to 230 inch pounds of torque with both metric
and English size sockets
•!High range torque wrench capable of up to 50 foot-pounds of torque with both metric
and English size sockets
•!Bettsometer for testing wing fabric strength
•!Syringe with capacity of at least 4 ounces for bleeding the hydraulic brakes
•!Propeller pitch gauge
•!Safety wire twisting pliers and safety wire
•!Air pump
•!Lubricants and other liquid/paste materials required by Rotax
•!Loctite 243, 567
•!Anti-seize lubricant
•!Plastic wire ties of various sizes
•!Oil resistant thread sealer (tape of paste)
Other items may be required that are not on this list.
1.4#Service#Difficulties#and#Errors#
Any service difficulties, errors in this manual, or product defects should be reported to North
Wing via the web site, fax, or telephone. Corrections will be made as appropriate and reported
on the North Wing UUM Inc. web site.

2.1.9&Torque Specifications and Securing
Before any fastener is torqued to specifications, it is important to assure at least one full thread
of the bolt will extend beyond the nut when tightened. If the nut does not extend at least that
far, the bolt thread itself may fail if tightened to specifications.
Not all bolt connections have specific torque requirements. There are three basic types of
bolt/nut connections that are addressed in the table below:
1.!Normal bolt/nut fasteners
2.!Nylock fasteners
3.!Castle nut fasteners
Normal bolt/nut fasteners will have torque specifications listed in the table below.
Nylock nuts are used for many applications. Some of those applications do not require
specific torque values while others do. For those applications where the bolt is exposed to
only shear forces, the nut should be tightened until there is no free play in the connection, or
all gap is eliminated between the nut and the fixtures being bolted together, then tightened
another quarter to half turn. These applications are referred to as “Snug” connections in this
manual. The limiting factor in the tightening of most Nylock applications on tubing is to avoid
distorting the tubing circular shape. For those applications where significant torque should
be used, a recommended torque is specified in the table below.
Castle nut fasteners are used for applications where the bolt is exposed only to shear stresses
and does not experience any longitudinal tensile stresses. The purpose of the castle nut is to
allow easy assembly and disassembly without the need for tools. Castle nuts must be secured
in place with a safety pin or ring of any appropriate design. For these fasteners some gap
between the bolt or nut under-side surface and the material being fastened is acceptable but
should not be excessive. That is, the nut should be tightened to remove all visible gap and
then adjusted to the nearest hole alignment for the safety pin. These types of attachments are
referred to in this manual as simply “Secured” as opposed to “Torqued” or “Snug”.
Some fasteners must be secured from loosening using either safety wire, ring safeties, or pin
safeties. The table below indicates which type of fastener should be used in each application,
the type of safety recommended for each where applicable, and the associated torque where
appropriate.

The trike center of gravity (CG) is adjusted by sliding the pivot block retaining collars forward
and aft to the desired position. The range is measured by the distance from the front edge of
the front retaining collar to the front tip of the keel tube (not nose bracket). See the sketch
below.
In its forward most position, the front collar is up against the control frame apex. This is a
distance of 50½” from the keel tube tip. The pivot block assembly may be moved rearward a
maximum of 2” resulting in a measurement from the keel tube tip to the front collar of 52½”.
The hang point is changed by loosening the split collar bolts evenly about 3 turns each with a
¼” Allen wrench. This should be enough to slide the collars to the desired position. Note! It
is helpful to have the wing nose up when moving the hang point forward, and the wing nose
down when moving the hang point rearward. This will allow the wing to slide in the pivot

block assembly with very little manual force. Retighten the collar bolts evenly. DO NOT
tighten just one collar bolt completely and then the other. This will distort and possibly
damage the keel tube.
Hang Point Moved Full Forward Hang Point Moved Full Back
Caution:
For loads greater than 850 lbs. the cg must be no further back than 51 inches. i.e. the range for
the cg for loads above 850 lbs is limited to 50½” – 51”. For loads less than 850 lbs, the cg
may be adjusted anywhere within the full range specified above.
2.3#Ground#Handling#
Care must be taken in maneuvering the trike on the ground for maintenance for several
reasons:
1.!Avoid overstressing the pivot block assembly that connects the trike to the wing
2.!Avoid causing the trike to flip onto the propeller by lifting the nose too high
3.!Avoid wear of the base tube due to rubbing against the nose tube
4.!Avoid wing tip damage by scraping the ground or hitting objects
2.3.1&Moving
To safely move the trike with the wing attached, use the following procedure:
1.!Anchor base tube securely to carriage either with a bungee holding the base tube
against the nose tube, or by using the seat belts to hold the base tube against the seat.
Be sure the wing is tilted at least 20°into the wind if trike is to be moved outside.
2.!Release the parking brake
3.!Confirm that the ignition magneto switches are off.

4.!Push on the propeller near the hub, steering left and right by pushing on one side of the
propeller harder than the other side. It is quite easy to steer the trike in the desired
direction using this method.
2.3.2&Parking and Tie Down
Never leave the trike outside without securing both the wing and the trike. Be sure the wing is
tilted into the wind, and secure the parking brake. For wind conditions greater than 5mph, the
wing should be secured using the tie down straps located inside the wing at the crosstube-to-
leading edge connection zipper. Position the wing at 90°to the wind direction so that the wind
tends to press the lowered wing down further. Anchor owner supplied straps to the tie down
straps inside the wing so as to hold this angle into the wind.
2.3.3&Lifting
The nose of the trike can be lifted using the hand hold underneath the nose of the wind fairing.
BE CAREFUL not to lift the nose too quickly or too high. Any trike will easily go beyond
the balance point, and can flip over onto the propeller causing substantial damage to the trike,
wing, and engine.
2.4#Lubrication#
The points requiring lubrication and the recommended lubricant is given in the following
table. Most bearings on North Wing S-LSA aircraft are permanently sealed and do not require
lubrication.
