Description of Tool Usage:

The C27047 lock set is used to hold the number 2 thru 5 or 8 thru 11 flight spoilers in the deployed position during ground maintenance. One lock assembly is used on each of the eight extended actuators. The locks are installed in clamshell fashion over each actuator rod; the two clamshell halves are held together via a hinge pin and a locking pin. A C27001 ground lock set is required to lock the number 1 and 12 outboard ground spoilers. A C27046 lock set is required to lock the number 6 and 7 inboard ground spoilers.
