Routing

Route the wires of the cable loom over the existing cable looms. 

Locate the Connector J1742A on STA 17011 (Fokker 100) or STA 14547 (Fokker 

70) at the RH side of the cabin to wheelbay spar. 

Route the ALD wires forwards to the Flight Compartment following the cable ducts in 

separation ABCD6 until STA 14381 (Fokker 100) or STA 11917 (Fokker 70). At 

above station route the wires over separation B6 up to the ceiling, following the 

existing cable looms. Route the wires forward over separation B6 and follow this wire 

separation over the existing cable routing to just before galley 1. Use the crossover 

to go to the LH side. Then route towards the flight compartment ceiling. Stow the 

wires (length 2 meters) as indicated by Figure 1. 

Locate the Connector J1747A or J1749A on STA 17011 (Fokker 100) or STA 14547 

(Fokker 70) at the LH side of the cabin to wheelbay spar. 

Route the ALA wires forwards to the Flight Compartment following the cable ducts in 

separation ABCD5 until STA 14381 (Fokker 100) or STA 11917 (Fokker 70). At 

above station route the wires over separation B5 up to the ceiling, following the 

existing cable looms. Route the wires forward over separation B5 and follow this wire 

separation over the existing cable routing to the flight compartment ceiling. Continue 

the cable routing and stow the wires (length 2 meters) as indicated by Figure 1.
