Subtask 20-11-11-911-053
A. General

(1) Make sure that all lockwire holes are drilled.

(2) Make sure that the assembly was torqued to the requirements of the figure.

(3) Use lockwire only one time.

(4) Single wirelocking is permitted if the locking length is short and lies close to the component locked.

(5) Double wirelocking is preferred and is essential if the locking length is long and unsupported and/or can become damaged.

NOTE: Do not use lockwire to prevent unwanted operation of controls or switches for any normal, standby or emergency services which can be required at any times during flight.

4. Procedure

Subtask 20-11-11-911-050
A. Single Wirelocking

(Ref. Fig. 201/TASK 20-11-11-991-001 SHEET 201.1)
(1) Put the lockwire into the hole.

(2) Keep the wire tight, twist a minimum of four times.

(3) Put one end through the hole in the item to which locking is to run.

NOTE: Do not cut the end that is not used until the wirelocking operation is completed. You can use it if the first end breaks.

(4) Bend the wire back through 180 and thread it under itself.

(5) Draw the wire tight and thread the end under at least two more times, making a minimum of two turns up to a maximum of four.

B. Double Wirelocking

(Ref. Fig. 201/TASK 20-11-11-991-001 SHEET 201.1)
(1) Put the lockwire into the hole in the first part and the ends equalized and bent around the head of the part.

(2) Twist the strands, while tight, until the twisted part is just short of the hole in the next unit.

The twisted portion must be within 3 mm (0.1181 in.) from the hole in either unit.
NOTE: The direction of wrap and twist of the strands must be such that the loop around the part comes under the strand which protudes from the hole so that the loop stays down and does not tend to slip up and leave a slack loop.

(3) Insert the highest strand through the hole in the second unit and do the above procedure.

(4) After the last unit is wired, continue to twist the wires to form a pigtail of three to five twists.

(5) Bend the cut ends of the pigtail in towards the item to prevent formation of a snag.

A. Check of the Wire

(1) Trim off the remaining wire and discard.

(2) Remove all pieces of off-cut wire from the aircraft structure.

(3) Make sure that locking is tight.

(4) Make sure that the wire shows no signs of kinking, peeling and other types of damage.

(5) If no protection was applied in the wire holes before installation, you must inject the adequate protective compound after wire installation Material No 05002 (SPECIAL MATERIALS (Material No. 05-002))  or Material No 05027C (SPECIAL MATERIALS (Material No. 05-027C))  .
