Airworthiness Directives; Embraer S.A. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Embraer S.A. Model ERJ 170 and ERJ 190 airplanes. This proposed 
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. Improper assembly of the 
fire extinguishing bottle might cause the extinguishing agent to be 
discharged toward the unselected cargo compartment rather than toward 
the cargo compartment with fire. This proposed AD would require an 
inspection of the HRD bottle for correct installation and to determine 
if the pressure switch is in the correct position, and re-installation 
if necessary; an inspection of the HRD and LRD bottle discharge heads 
to determine the part number and replacement if necessary; and, for 
certain airplanes, an inspection to determine the part numbers of the 
HRD and LRD electrical connectors, and relocation if necessary. We are 
proposing this AD to prevent the inability of the fire extinguishing 
system to suppress fire.

DATES: We must receive comments on this proposed AD by November 30, 
2012.

Discussion

    The Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC), 
which is the aviation authority for Brazil, has issued Brazilian 
Airworthiness Directives 2012-07-01 and 2012-07-02, both effective July 
30, 2012 (referred to after this as ``the MCAI''), to correct an unsafe 
condition for the specified products. The MCAI states:

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 possibility 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.

* * * * *
Required actions include an inspection of the HRD bottle for correct 
installation and to determine if the pressure switch is in the correct 
position, and re-installation if necessary; an inspection of the HRD 
and LRD bottle discharge heads to determine the part number and 
replacement if necessary; and, for certain airplanes, an inspection to 
determine the part numbers of the HRD and LRD electrical connectors, 
and relocation if necessary. You may obtain further information by 
examining the MCAI in the AD docket.

Relevant Service Information

    Embraer has issued the following service bulletins to correct the 
unsafe condition identified in the MCAI.
     EMBRAER Service Bulletin 170-26-0011, Revision 01, dated 
June 19, 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 01, dated 
June 19, 2012 (for Model ERJ 190-100 STD, -100 LR, -100 ECJ, and -100 
IGW airplanes; and Model ERJ 190-200 STD, -200 LR, and -200 IGW 
airplanes).
     EMBRAER Service Bulletin 190LIN-26-0006, Revision 01, 
dated June 19, 2012 (for Model ERJ 190-100 STD, -100 LR, -100 ECJ, and 
-100 IGW airplanes; and Model ERJ 190-200 STD, -200 LR, and -200 IGW 
airplanes).

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 163 products of U.S. registry. We also estimate that 
it would take about 7 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $85 per 
work-hour. Based on these figures, we estimate the cost of the proposed 
AD on U.S. operators to be $96,985, or $595 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 1 work-hour and require parts costing $68,588, for a cost of 
$68,673 per product. We have no way of determining the number of 
products that may need these actions.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. ``Subtitle VII: Aviation 
Programs,'' describes in more detail the scope of the Agency's 
authority.
    We are issuing this rulemaking under the authority described in 
``Subtitle VII, Part A, Subpart III, Section 44701: General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would not 
have a substantial direct effect on the States, on the relationship 
between the national

[[Page 63274]]

Government and the States, or on the distribution of power and 
responsibilities among the various levels of government.
    For the reasons discussed above, I certify this proposed 
regulation:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska; and
    4. Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.

I and Part II, as applicable, of the Accomplishment Instructions of 
EMBRAER Service Bulletin 170-26-0011, Revision 01, dated June 19, 
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

further flight, replace the discharge bottle with a discharge bottle 
having the same part number.

bottle electrical connectors. If the part numbers of the HRD or LRD 
bottle electrical connectors are not the part numbers specified in 
Figure 1 of EMBRAER Service Bulletin 170-26-0011, Revision 01, dated 
June 19, 2012 (for Model ERJ 170-100 LR, -100 STD, -100 SE, and -100
