Common Information
TASK 71-00-02-400-020-A00 (A1-PPBU) - Install The Thermal Anti-Ice (TAI) Duct, Installation-020
General
Fig/item numbers in parentheses in the procedure agree with those used in the EIPC. Only the primary Fig/item numbers are used. For the service bulletin alpha variants refer to the EIPC.
For all parts identified in a different Chapter/Section/Subject, the applicable Chapter/Section/Subject comes before the Fig/item number.
Lubricate all the bolt shanks given in this procedure with CoMat 10-073 SYNTHETIC GREASE, MoDISULFIDE, Mo disulphide. Lubricate all the bolt holes with CoMat 10-072 ANTISEIZE COMPOUND (MoDISULFIDE), unless other lubricants are referred to in the procedure.
Transportation covers/blanks must be removed immediately before the installation of the components.
For the torque tightening procedures, refer to the SPM TASK 70-41-00-400-501 and the SPM TASK 70-41-01-400-501.
After assembly apply CoMat 07-038 AIR DRYING ENAMEL to any damaged surface protection, joint flanges and attach parts. Use the correct color of the air drying enamel. Refer to the SPM TASK 70-38-21-380-501.
Special torque data and assembly tolerances are included in this procedure.
Special torque data is identified with the symbol * after the torque value.

Attach the coupling ICE AND RAIN PROTECTION-ANTI-ICE DUCTS (30-21-49, 01-080) to the duct ICE AND RAIN PROTECTION-ANTI-ICE DUCTS (30-21-49, 01-070). Tighten the coupling.
Install the duct to the female link bearing ICE AND RAIN PROTECTION-ANTI-ICE DUCTS (30-21-49, 01-170) with the bolt, the flanged bush, the washer and the nut ICE AND RAIN PROTECTION-ANTI-ICE DUCTS (30-21-49, 01-130 , ICE AND RAIN PROTECTION-ANTI-ICE DUCTS 01-150, ICE AND RAIN PROTECTION-ANTI-ICE DUCTS 01-160 and ICE AND RAIN PROTECTION-ANTI-ICE DUCTS 01-140). Make sure the washer is installed correctly. Refer to the detail on A.
Torque the nut ICE AND RAIN PROTECTION-ANTI-ICE DUCTS (30-21-49, 01-140) to 85 to 105 lbf.in. (10 to 12 Nm).
NOTE
It is not necessary to lubricate the hose 237 nut.Pre SBN 71-0069 and Pre SBE 71-0070: Connect the hose 237 to the duct. Torque the hose nut to 175 to 195 * lbf.in (19.78 to 22.0 Nm).
Install the duct.
