9-3 LOCKWIRE PROCEDURE (cont'd)
Various examples of lockwiring are shown in Figure 9-2, "General Lockwire Patterns."
1. All items to be lockwired must be properly torqued. Applying torque that is above or
below specified limits to obtain alignment of the holes is not permitted.
2. Lockwire shall be installed in such a manner that the strand through the hole will have
a tendency to pull the in the tightening direction.
3. Insert half of the required length of lockwire through the first unit and bend around the
head of the unit. The direction of wraps and twist of strands shall be such that the
loop around the unit comes under the strand protruding from the hole so that the loop
will stay down and will not tend to slip up and leave a slack loop.
4. Twist the strands while taut until the twisted part is just short of a hole in the next unit.
The twisted portion should be within one-eighth (1/8) inch from the hole in either unit.
5. Insert the uppermost strand through the hole in the second unit and follow the rules in
paragraph three.
6. After lockwiring the last unit, continue twisting the wire to form a pigtail providing a
minimum of four twists to insure that the pigtail will not unravel. Cut off the excess
lockwire and bend the pigtail toward the part and against the bolt head flats. DO NOT
ALLOW THE PIGTAIL TO EXTEND ABOVE THE BOLT HEAD.
