Slat/Flap Systems: Rigging requirements for Global 7500/ 8000 aircraft

ATA: 27-51

Effectivity: Global 7500/8000 aircraft

This article provides details on what must be performed on aircraft when any slat or flap component is affected or disturbed during maintenance. 

Any time a slat or flap mechanical component is disconnected or replaced from the slat or flap system, a rigging check must be performed on the affected system. 

• Inboard-flap control surfaces- Rigging check 

• Outboard-flap control surfaces- Rigging check 

• Slat No. 1 - Rigging check 

• Slat No. 2 - Rigging check 

• Slat No. 3 - Rigging check 

• Slat No. 4 - Rigging check 

 The rigging check may imply that the aircraft is defueled and on a jack to make sure that the bending of the wing  does not affect the 0° position. 

• For the flap system: Less than 11,000 pounds (5,500 pounds per wing) is allowed with the aircraft on the ground (RIL GX-0671). 

• For the slat system: Aircraft must be pressure defueled and on jacks. 

If the rigging check fails, then the full surface rigging must be performed per AMP. 

Once the mechanical 0° position is confirmed/achieved, then the Slat Flap Electronic Control Unit (SFECU) electrical rigging must be performed to record the system's 0° position. 

• Flap system - Electrical rigging 

• Leading edge slat-system - Electrical rigging 

SFECU and sensor replacement: 

SFECU and position sensor replacement require an electrical rigging to be performed, which also implies a rigging check, defueled and on jacks. 

This article is a high-level summary of the AMP.

Engineering does not allow deviation from the AMP.
