### Airworthiness Directives; Embraer S.A. **Airplanes**

**AGENCY** 

### : Federal Aviation Administration (FAA), Department of Transportation (DOT).

**ACTION** 

### : Final rule.

**SUMMARY** 

### : We are adopting a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 170 and ERJ 190 airplanes. 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. 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 AD requires 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 identify the HRD and LRD bottle electrical connectors, and relocation if necessary. We are issuing this AD to prevent the inability of the fire extinguishing system to suppress fire.

**DATES** 

### : This AD becomes effective May
3, 2013.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of May 3, 2013.

**SUPPLEMENTARY INFORMATION** 

### :

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on October 16, 2012 (77 FR 63272). That NPRM proposed to correct an unsafe condition for the specified products. The Mandatory Continuing Airworthiness Information (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 identify the HRD and LRD bottle electrical connectors, and relocation if necessary. You may obtain further information by examining the MCAI in the AD docket.

Comments

We gave the public the opportunity to participate in developing this AD. We considered the comments received.
Request To Refer to Revised Service Information

Embraer requested that we revise the NPRM (77 FR 63272, October 16, 2012) to include the latest revision of the referenced service information. Embraer also requested that we provide credit for actions done using the following service bulletins.

• Embraer Service Bulletin 170–26– 0011, Revision 01, dated June 19, 2012.

• Embraer Service Bulletin 190–26– 0011, Revision 01, dated June 19, 2012.

• Embraer Service Bulletin 190LIN– 26–0006, Revision 01, dated June 19,

2012.

We agree to refer to the following service bulletins in this AD as requested. We have revised paragraphs (c), (g), and (h) of this AD accordingly.

• Embraer Service Bulletin 170–26– 0011, Revision 02, dated October 17,

2012.

• Embraer Service Bulletin 190–26– 0011, Revision 02, dated October 17,

2012.

• Embraer Service Bulletin 190LIN– 26–0006, Revision 02, dated September
28, 2012.

We have also added new paragraph (i) to this AD (and re-identified subsequent paragraphs accordingly) to allow credit for actions done previously using the following service bulletins.

• Embraer Service Bulletin 170–26– 0011, Revision 01, dated June 19, 2012.


## 19091 Federal Register / Vol. 78, No. 61 / Friday, March 29, 2013 / Rules and Regulations

• Embraer Service Bulletin 190–26– 0011, Revision 01, dated June 19, 2012.

• Embraer Service Bulletin 190LIN– 26–0006, Revision 01, dated June 19,

2012. Request To Clarify the Proposed Applicability for Certain Actions

Embraer requested that we clarify the applicability for paragraphs (g), (h), and (i) of the NPRM (77 FR 63272, October 16, 2012), for airplanes subject to Embraer Service Bulletin 190LIN–26– 0006, Revision 02, dated September 28, 2012. Embraer stated that Embraer Service Bulletin 190LIN–26–0006, Revision 02, dated September 28, 2012, applies only to Model ERJ 190–100 ECJ airplanes, and requested that we revise paragraphs (g), (h), and (i) of the NPRM, accordingly.

We partially agree. We disagree with revising paragraph (i) of the NPRM (77 FR 63272, October 16, 2012). Paragraph (i) of the NPRM—now paragraph (j) of this AD—has no reference to Embraer Service Bulletin 190LIN–26–0006, Revision 02, dated September 28, 2012; therefore, we have made no change to that paragraph.

We agree that Embraer Service Bulletin 190LIN–26–0006, Revision 02, dated September 28, 2012, affects only Model ERJ 190–100 ECJ airplanes. Embraer Service Bulletin 190–26–0011, Revision 02, dated October 17, 2012, does not affect Model ERJ 190–100 ECJ airplanes. We have revised paragraphs (c), (g), and (h) of this AD accordingly.
Request To Clarify Inspection Requirement

Embraer requested that we clarify that the inspection is for proper identification of the electrical connectors, rather than for specific electrical connector part numbers, as specified in the NPRM (77 FR 63272, October 16, 2012). Embraer stated that the electrical connector identification is not the same as the part number.

We agree to clarify the inspection requirement as requested. We have revised paragraph (g)(3) of this AD to require the inspection to identify the HRD and LRD bottle electrical

connectors. Additional Change to NPRM

We have also revised paragraphs (g)(2) and (h)(2) of this AD to clarify the replacement part.

Conclusion

We reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting the AD with the changes described previously and minor editorial changes. We have determined that these changes:

• Are consistent with the intent that was proposed in the NPRM (77 FR 63272, October 16, 2012) for correcting the unsafe condition; and

• Do not add any additional burden upon the public than was already proposed in the NPRM (77 FR 63272, October 16, 2012).
Costs of Compliance

We estimate that this AD will affect 163 products of U.S. registry. We alsoestimate that it will take about 7 workhours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this AD to the 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 AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national 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 that this AD:

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 AD and placed it in the AD docket.
Examining the AD Docket

You may examine the AD docket on the Internet at http:// www.regulations.gov; or in person at the Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM (77 FR 63272, October 16, 2012), the regulatory evaluation, any comments received, and other information. The street address for the Docket Operations office (telephone (800) 647–5527) is in the **ADDRESSES**

### Airworthiness Directives; The Boeing **Company Airplanes**

**AGENCY** 

### : Federal Aviation Administration (FAA), DOT.

**ACTION** 

### : Final rule.

**SUMMARY** 

### : We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 777 airplanes. This AD was prompted by reports that escape slides/rafts did not deploy due to galvanic corrosion of the door-mounted slide/raft packboard release mechanisms. This AD requires doing a general visual inspection of the housing assembly of the packboard release mechanism to determine if its surface treatment has been sealed, and if the surface of the housing assembly is unsealed, replacing the housing assembly with a new or serviceable housing assembly. We are issuing this AD to detect and correct corrosion of the packboard release mechanisms, which could interfere with escape slide/raft deployment, prohibit doors from opening in the armed mode, and cause consequent delay and injury during evacuation of passengers and crew from the cabin in the event of an emergency.

**DATES** 

### : This AD is effective May 3, 2013.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of May 3, 2013.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM published in the Federal Register on January 19, 2012 (77 FR 2666). That NPRM proposed to require doing a general visual inspection of the housing assembly of the packboard release mechanism to determine if its surface treatment has been sealed, and if unsealed, replacing the housing assembly with a new or serviceable housing assembly.
