The vord “safotying" te a shop term universally used in the aircratt
industry. Briofly, sefetying 19 defined eo "Securing by-vartous means any
nut, bolt, or tumbuckle on the atrcraft, so that vitretion or rotation will
not cause it to loosen during operation."
‘Three basic methods are used in safetying; safety vire, cotter pins,
and self-locking nuts or retainer vashers and pal mute,
Wire, either soft brase or steel, is used on cylinder atuds, control
cable turnbuckles, and engine eccessory attaching bolts.
Cotter pina are used on airplane and engine controls, landing gear
and tail vheo! assomblies, or any other point vhere.a turning or actuating
movenent tukes place.
Self locking nute or vashere are used only on fairing attachments, or
other non-noving couponents of the airplane,
Self locking nuts are secured with fibre insorte at the inside top of
‘the nut. ‘Thie lock nut should be replaced any time it is renoved from the
bolt.
Three typos of lock washers (external spider, internal spider, end
split types) ere used at points on non-noving parts.
Pal or spood nuts include designe which force the nut thread against
‘the bolt or screw thread vhen tightened, ‘These nute should never be used
over egatn end should be replaced vith new when removed.
CAUIION: In tho event any sefetying should be replaced on the aircraft,
Xt should be inepected by a licensed aircraft or engine mechanic.
Substitution of any one of the three methods described above, one
for enother, is not permissible. ‘RIGGING INSTRUCTIONS T
LOVELING:
‘Tevel in fore and aft direction by using the front window 9111 or any
portion of the cabin floor as a reference for a bubble level.
ING Broom .
‘DIEEDRAL - The plus 2° angle of dihedral ts fixed by the length of the front strut.
ANGLE OF INCIDENCE - Tho plus 1° sagle of incidence 1s fixed in the manufacture of
‘the airplane, et the wing root fittings on the fuselage. The engle of incidence at
the rib nearest the atrut point attachuent fitting of the ving may be corrected to
agreo with the engle of incidence st the root, by adjusting the screy adjustment
fat the lover end of the rear etyut whore it attaches to tho front strut. This
provides zero washout.#

Adjust turbuckles to obtain 22 -26 cable tension.
ELEVATOR REGoING:
‘lace protractor so both ends of the level are resting on fabric supported

‘The above readings should be obtained by adjusting the turnbuckles; with the

‘¥—Tt the Givpiane seams to have © tondoncy toverd Wing heaviness, the necessary
vash in or vash out may be secured by adjusting the rear strut at ite lower
attaclmont point. Wash out (reduce tip incidence) the high (11ght) wing one degree;
then, 1f necessary, vash in tho lov (heavy) wing. CAUTION: Only a C.A.A. licensed
airoraft mechanic should attempt the assembly and rigging of vings end strute. ASSINBLT INSTRUCTIONS FOR EXPORT AIRCRAFT
As the aircraft 19 packaged for export, all correct bolts are attached to
the prover fittings. All parts should fit easily without forcing or distortion
of any fittings. If any difficulty 1s encounterod in assembly, inspect carefully
for evidence of dauege inflicted in ehiynent or handling.
I~ TALL SUPPORT WIRES
‘Tho eupport wires on the horizontal stabilizer should be tensioned to
give the teil asvenbly rigidity. The horizontal ourfaces are rigged
parallel to the ving plane and the vertical fin rigged perpendicular
‘to the ving plane.
IT - ELEVATORS
Adjust the turnbuckles to attain the correct cable tension, end check the
‘travela. (Seo rizging instructions). Be certain that the stick clears the
front and rear esate.
TIT - AttzRons
Adjust the tumbucklos in the cabin so each aileron 'droope’ about
Finch belov the trailing edge of the wing, when the control atick 12
Centored. (See rigsing instructions for correct tonsions end travel.)
