WARNING: MAKE SURE THAT PERSONS AND EQUIPMENT ARE CLEAR OF THE LEADINGEDGE AND TRAILING EDGE FLAPS AND FLAP DRIVE MECHANISMS BEFOREYOU MOVE THE FLAP CONTROL LEVER. WITH HYDRAULIC POWERREMOVED, THE FLAPS WILL MOVE AUTOMATICALLY BY ELECTRICALPOWER WHEN YOU MOVE THE FLAP CONTROL LEVER. THIS CAN CAUSEINJURY TO PERSONS OR DAMAGE TO EQUIPMENT.
WARNING: YOU MUST CAREFULLY DO THE STEPS IN THE TASK BELOW TO INSTALL THELEADING EDGE FLAP SAFETY LOCKS. THE LEADING EDGE FLAPS CANMOVE QUICKLY IF YOU DO NOT INSTALL THE SAFETY LOCKS CORRECTLY.THIS CAN CAUSE INJURY TO PERSONS OR DAMAGE TO EQUIPMENT.
(2) For tanks 1 and 2, extend the leading edge flaps and install leading edge flap locks (Ref27--81--00/201).
C. WING BRACKET INSTALLATION (BOTH WINGS)
NOTE: The sequence of steps 1 -- 20 may be rearranged to facilitate the installation, as long as allinstructions are accomplished.
NOTE: Wing brackets are installed in leading edge between LES 126.00 and 139.00, between stringer#1 and stringer #2. Stringers are attached to the underside of the leading edge skin. Stringer #1is closest to leading edge of wing, and supports leading edge flap tailgate fitting. Stringer #2 isapproximately four inches behind #1. Span--wise location of bracket 30212--1304--0104 maybe adjusted between LES 126.00 and LES 139.00, so that fastener holes in rivet plate30212--1305--0104 may either re--use existing holes from tab removed in step (2), or may haveproper spacing from existing holes if they are not re--used. Fill any unused holes.
(1) If three power leads are attached to tab on stringer 2, remove leads from tab.
(2) If the leading edge micro switch harness is attached to tab on stringer 1, remove harness from tab,and remove the tab from stringer 1.
(3) Temporarily locate rivet plate P/N 30212--1305--0104 on the forward side of stringer 1. The angle of30212--1305--0104 shall be opposite the stringer angle. (See Figure 1) If possible, pick up one holefrom the previously removed tab.
(4) It is recommended to use a hole--finder (reference B737 SRM 51--40--02, Paragraph 2b) to transferthree holes from rivet plate 30212--1305--0104 to aft side of stringer 1. This will allow drilling from aftside, thereby allowing more room for tooling.
(5) Match drill 2 ea. 0.11 inch diameter holes through stringer 1 and install temporary fasteners.
(6) Match drill one 0.228 +.005/--.003 diameter hole through center hole of rivet plate30212--1305--0104 and stringer 1.
