Compliance
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Required actions
For airplanes on which Embraer Service Bulletin 170-26-0011, dated December 1, 2011 (for Model ERJ 170-100 LR, -100 STD, -100 SE., and -100 SU airplanes; and Model ERJ 170-200 LR, -200 SU, and -200 STD airplanes); Embraer Service Bulletin 190-26-0011, dated December 1, 2011 (for Model ERJ 190-100 STD, -100 LR, and -100 IGW airplanes; and Model ERJ 190-200 STD, -200 LR, and -200 IGW airplanes); or Embraer Service Bulletin 190LIN-26-0006, dated December 1, 2011 (for Model ERJ 190-100 ECJ airplanes); has not been accomplished as of the effective date of this AD: Within 3,000 flight hours after the effective date of this AD, do the actions specified in paragraphs (g)(1), (g)(2), and (g)(3) of this AD. All actions must be done in accordance with Part I and Part II, as applicable, of the Accomplishment Instructions of Embraer Service Bulletin 170-26-0011, Revision 02, dated October 17, 2012 (for Model ERJ 170-100 LR, -100 STD, -100 SE., and -100 SU airplanes; and Model ERJ 170-200 LR, -200 SU, and -200 STD airplanes); Embraer Service Bulletin 190-26-0011, Revision 02, dated October 17, 2012 (for Model ERJ 190-100 STD, -100 LR, and -100 IGW airplanes; and Model ERJ 190-200 STD, -200 LR, and -200 IGW airplanes); or Embraer Service Bulletin 190LIN-26-0006, Revision 02, dated September 28, 2012 (for Model ERJ 190-100 ECJ airplanes). (1) Do a general visual inspection of the HRD bottle to determine if it is correctly installed and if the pressure switch is in the correct position. If the bottle is not correctly installed or the pressure switch is in the incorrect position, before further flight, remove and re-install the HRD bottle. (2) Inspect the HRD and LRD bottle discharge heads to determine the part number. If the part number of the discharge heads is not the part number specified in Figure 3 of Embraer Service Bulletin 170-26-0011, Revision 02, dated October 17, 2012 (for Model ERJ 170-100 LR, -100 STD, -100 SE., and -100 SU airplanes; and Model ERJ 170-200 LR, -200 SU, and -200 STD airplanes); Embraer Service Bulletin 190-26-0011, Revision 02, dated October 17, 2012 (for Model ERJ 190-100 STD, -100LR, and -100 IGW airplanes; and Model ERJ 190-200 STD, -200 LR, and -200 IGW airplanes); or Embraer Service Bulletin 190LIN-26-0006, Revision 02, dated September 28, 2012 (for Model ERJ 190-100 ECJ airplanes): Before further flight, replace the discharge bottle with a discharge bottle of the same part number that has a correct discharge head part number, as shown in Figure 3 of Embraer Service Bulletin 170-26-0011, Revision 02, dated October 17, 2012 (for Model ERJ 170-100 LR, -100 STD, -100 SE., and -100 SU airplanes; and Model ERJ 170-200 LR, -200 SU, and -200 STD airplanes); Embraer Service Bulletin 190-26-0011, Revision 02, dated October 17, 2012 (for Model ERJ 190-100 STD, -100LR, and -100 IGW airplanes; and Model ERJ 190-200 STD, -200 LR, and -200 IGW airplanes); or Embraer Service Bulletin 190LIN-26-0006, Revision 02, dated September 28, 2012 (for Model ERJ 190-100 ECJ airplanes), as applicable. (3) Inspect to identify the HRD and LRD bottle electrical connectors. If the identification of the HRD or LRD bottle electrical connectors is not specified in Figure 1 of Embraer Service Bulletin 170-26-0011, Revision 02, dated October 17, 2012 (for Model ERJ 170-100 LR, -100 STD, -100 SE., and -100 SU airplanes; and Model ERJ 170-200 LR, -200 SU, and -200 STD airplanes); Embraer Service Bulletin 190-26-0011, Revision 02, dated October 17, 2012 (for Model ERJ 190-100 STD, -100LR, and -100 IGW airplanes; and Model ERJ 190-200 STD, -200 LR, and -200 IGW airplanes); or Embraer Service Bulletin 190LIN-26-0006, Revision 02, dated September 28, 2012 (for Model ERJ 190-100 ECJ airplanes): Before further flight, relocate the HRD or LRD bottle electrical connectors by re-routing the electrical harness.
Unsafe condition
This AD was prompted by a report that high rate discharge (HRD) bottle explosive cartridges of a cargo compartment fire extinguisher system were swapped between the forward and aft cargo compartments. Additional investigation also revealed the possibility of swapping between the electrical connectors of the HRD and low rate discharge (LRD) bottles, and a rotated installation of the HRD bottle. We are issuing this AD to prevent the inability of the fire extinguishing system to suppress fire.
Affected ADs
None.

TrackAD holds all 12,278 of them and matches them against the aircraft you actually look after — airframe, engine, propeller and appliances in one pass — then works out what falls due and when.
- Bring your existing list in from a spreadsheet Paste the rows straight out of Excel. Headers like C/W Date and N/A are read for you.
- A copy that works when this does not One file. No internet, no login, no this software running. For the morning something has to be produced and the computer is not cooperating.
