### , 2012. Not Applicable. CANCELLATION / REVISION:

REA SON: It was found during an inspection of the cargo compartment fire extinguisher system that High Rate Discharge (HRD) bottle explosive cartridges were swapped between forward and aft cargo compartments. Additional investigation has also revealed the pos sibility of swapping between the electrical connectors of the HRD and Low Rate Discharge (LRD) bottles and a rotated installation of the HRD bottle . Such improper assembly of the fire extinguishing bottle may cause the extinguishing agent to be discharged toward the unselected cargo compartment rather than toward the cargo compartment with fire, resulting in an insufficient concentration of fire extinguishing agent in the cargo compartment with fire, and consequent inability of the fire extinguishing system to suppress fire. Since this condition may occur in other airplanes of the same type and affects flight safety, a corrective action is required. Thus, sufficient reason exists to request compliance with these requirements in the indicated time limit. Cargo Compartment Fire Extinguisher System

– High and Low Rate Discharge Bottle inspection and relocation/replacement, if necessary. REQU IRED ACTION:

Required as indicated below, unless already accomplished. COMPLIANCE: Low and High Rate Discharge bottles insp ection and correction/replacement (a) Within 3.000 flight hours after the effective date of this AD, do a General Visual Inspection (GVI) to detect discrepancies on the assembly of the cargo compartment fire extinguisher LRD and HRD bottles, electrical con nectors, harnesses and in the Discharge Heads of the HRD and LRD bottles in accordance with the Accomplishment Instructions of Embraer SB 170
