VORTEX GENERATORS - REMOVAL/INSTALLATION
1. Equipment and Materials
A. Hardwood stick
B. Nonmetallic scraper
C. Solvent - Final Cleaning of Metal Prior to Non-structural Bonding (Series 88) (Ref AMM/SOPM 20-30-88).
D. Adhesive - BMS 5-19, Class B-1/2, Type 44 (Ref 20-30-31)
E. Vortex Generator Installation Tool - MIT69-58847-43 (Left Side) MIT69-58847-44 (Right Side)
2. Remove Vortex Generator
A. Drill out rivets, or remove bolts.
B. Pry off vortex generator with hardwood stick.
3. Prepare for Installation
A. Remove residual bonding agent with nonmetallic scraper and solvent.
B. Clean faying surfaces with solvent.
4. Install Vortex Generator
A. If installing lower vortex generators, locate generators.
(1)
Orient vortex generator installation tool along skin trim lines at stringer S-12 and station 1088 per Fig. 401.
(2)
Check edge distance of holes where fasteners were removed and orient tool to provide best edge distance for new fasteners. Secure tool with tape.
(3)
Measure offset between upper and lower edges of tool and edge of skin at station 1088. Ensure difference between these measurements is less than 0.68 inch.
(4)
Locate vortex generator in tool cutouts.
B. If installing upper vortex generator, orient vortex generator per Fig. 402.

C. Bond vortex generator or vortex generator assembly to fuselage surface with 100% coverage. Form 0.05 by 0.05 inch fillet around edge with excess adhesive.
(1)
Thoroughly blend base compound with activator according to manufacturer's instructions. Do not thin adhesive.
(2)
Apply thin, uniform coat of blended adhesive to each faying surface.
(3)
Assemble immediately, applying sufficient pressure to ensure complete contact of faying surfaces. A continuous bead of extruded adhesive usually indicates proper contact.
D. Remove installation tool.
E. Install rivets, or bolts.
(1) Rivet vortex generator assembly to stringers S-2, S-3, S-4, and S-5A.
NOTE: Installation of rivets will hold vortex generator in place and it is not necessary to wait for full cure of sealant before dispatching airplane. Airplane may be dispatched after sealant has set until it is firm. Although not fully cured, the sealant will not be blown out by the airstream.
F. Cure at 75 to 80°F.
(1) The time to obtain handling strength is 16 hours. Full cure is not obtained for a week or more.
2) Curing may be accelerated by applying heat not to exceed a bond line temperature of 120°F. As a rough rule of thumb the cure time will be reduced 50% for each 20°F rise in temperature. Conversely, temperatures below 75°F will greatly increase the required cure time.
