Installation of the Vertical Stabilizer Tip
WARNING:
PUT THE SAFETY DEVICES AND THE WARNING NOTICES IN POSITION BEFORE YOU START A TASK ON OR NEAR:
- THE FLIGHT CONTROLS
- THE FLIGHT CONTROL SURFACES
- THE LANDING GEAR AND THE RELATED DOORS
- COMPONENTS THAT MOVE.
WARNING:
BE CAREFUL WHEN YOU USE CONSUMABLE MATERIALS. OBEY THE MATERIAL MANUFACTURER'S INSTRUCTIONS AND YOUR LOCAL REGULATIONS.
CAUTION:
MAKE SURE YOU DO NOT DAMAGE THE ANTENNA.
ZONE: 324
1. Reason for the JobNOTE: You can remove or install the vertical stabilizer tip with your hands as an alternative to the SLING-UNIVERSAL,TAIL PLANE and the CRANE HEIGHT 15 M (50 FT). If you do not use the sling and the crane but operate the vertical tip manually, you must be careful not to cause damage to the vertical stabilizer.

A. Preparation of the Vertical Stabilizer Tip for Installation
(1) Do a check for the condition of the sealant on the mating surfaces along the spar-box and the leading-edge rib. If necessary, replace the sealant:
(a) Remove the sealant from the mating surfaces along the spar-box and the leading-edge rib with a SCRAPER - NON METALLIC.
(b) Apply the Polysulfide Sealant-Low Adhesion Brushable - (Material No.06AEA1) to the mating surfaces of the tip (1). Do not apply the sealant to the bonding points.
(c) Apply the release agent Release Agent-- Liquid Wax - (Material No.14DBB1) along the mating surfaces of the spar-box and the leading-edge rib. Do not apply the release agent to the bonding points.
(2) Clean the component interfaces and the adjacent area.
(3) Do an inspection of the component interfaces and the adjacent area.
(4) Make sure that the parts retained from the removed component are clean and in the correct condition.
(5) Examine the anchor nuts on the leading-edge rib and the spar-box for good condition.
