Discussion Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170 Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain EMBRAER Model ERJ 170 airplanes. This AD requires inspecting for excess sealant applied to the attachment bolts of the negative pressure relief valve, and performing corrective actions if necessary. This AD results from reports that excess sealant was applied to the PO 00000 Frm 00011 Fmt 4700 Sfmt 4700 The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to certain EMBRAER Model ERJ 170 airplanes. That NPRM was published in the Federal Register on April 21, 2006 (71 FR 20593). That NPRM proposed to require inspecting for excess sealant applied to the attachment bolts of the negative pressure relief valve, and performing corrective actions if necessary. Comments We provided the public the opportunity to participate in the development of this AD. We received no E:\FR\FM\20JNR1.SGM 20JNR1 35384 Federal Register / Vol. 71, No. 118 / Tuesday, June 20, 2006 / Rules and Regulations comments on the NPRM or on the determination of the cost to the public. Clarification of Serial Number Range To clarify the range of the serial numbers of the affected airplanes we have added the word ‘‘inclusive’’ to the applicability of the AD. Conclusion We have carefully reviewed the available data and determined that air safety and the public interest require adopting the AD with the change described previously. We have determined that this change will neither increase the economic burden on any operator nor increase the scope of the AD. Costs of Compliance This AD will affect about 54 airplanes of U.S. registry. The required actions will take about 1 work hour per airplane, at an average labor rate of $80 per work hour. Based on these figures, the estimated cost of this AD for U.S. operators is $4,320, or $80 per airplane. 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. wwhite on PROD1PC61 with RULES Regulatory Findings We have 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; VerDate Aug<31>2005 16:35 Jun 19, 2006 Jkt 208001 (2) Is not a ‘‘significant rule’’ under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and (3) 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. See the ADDRESSES section for a location to examine the regulatory evaluation.

ACTION: Final rule. AGENCY: The FAA is superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 727–200 series airplanes. That AD currently requires initial and repetitive inspections for cracks in the forward frame of the No. 3 cargo door cutout; and corrective actions, if necessary. The existing AD also provides for an optional structural modification, which terminates the repetitive inspections. This new AD reduces the compliance time for the initial inspections and adds an optional method of inspection for both the initial and repetitive inspections. This AD also adds initial and repetitive inspections of an additional area, and repair if necessary. Additionally, this AD clarifies that the previously optional structural modification is now required by other rulemaking. This AD results from additional reports of cracking in the forward frame of the No. 3 cargo door cutout. We are issuing this AD to detect and correct cracking of the forward frame and fuselage skin of the No. 3 cargo door cutout, which could result in failure of the frame and skin, and consequent rapid decompression of the airplane.

Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that supersedes AD 86–17–05 R1, amendment 39–5714 (52 FR 32534, August 28, 1987). The existing AD applies to certain Boeing Model 727– 200 series airplanes. That NPRM was published in the Federal Register on March 7, 2006 (71 FR 11345). That NPRM proposed to continue to require initial and repetitive inspections for cracks in the forward frame of the No. 3 cargo door cutout; and corrective actions, if necessary. That NPRM proposed to reduce the compliance time for the initial inspections and add an optional method of inspection for both the initial and repetitive inspections. That NPRM also proposed to add initial and repetitive inspections of an additional area, and repair if necessary. Additionally, that NPRM clarified that the previously optional structural modification is now required by other rulemaking. Comments We provided the public the opportunity to participate in the PO 00000 Frm 00013 Fmt 4700 Sfmt 4700 35385 development of this AD. We have considered the comments that have been received on the NPRM. Request for Clarification of Certain Language Boeing requests that certain language be added to the Actions Since Existing AD was Issued section of the NPRM to clarify that the forward frame is the subject of the findings and that the skin and doubler in the area are also involved as an area of concern. We agree that adding the suggested language would clarify the location of the subject unsafe condition (i.e., the forward frame of the No. 3 cargo door cutout, along with the surrounding skin and doubler). However, because that section of the NPRM is not restated in the final rule, we find that no change to the AD is necessary in this regard. Request To Correct AD Number in Restatement of Requirements Heading Boeing points out that there is a typographical error in the AD number identified in the ‘‘REQUIREMENTS OF AD 86–17–05 R1 WITH REDUCED THRESHOLD AND NEW OPTIONAL INSPECTION METHOD:’’ heading in the regulatory text of the NPRM, and requests that the error, ‘‘AD 86–17–05 RL,’’ be corrected to read ‘‘AD 86–17– 05 R1.’’ We agree. We have verified that an error did occur in the AD number in that heading during printing of the NPRM. That AD number is correct in this final rule. Conclusion We have carefully reviewed the available data, including the comments that have been received, and determined that air safety and the public interest require adopting the AD with the change described previously. We have determined that this change will neither increase the economic burden on any operator nor increase the scope of the AD. Costs of Compliance There are about 269 airplanes of the affected design in the worldwide fleet. The new requirements of this AD add no additional economic burden. The current costs for U.S. operators to comply with this AD are repeated for the convenience of affected operators, as follows: E:\FR\FM\20JNR1.SGM 20JNR1

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

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain EMBRAER Model ERJ 170 airplanes. This AD requires inspecting 
for excess sealant applied to the attachment bolts of the negative 
pressure relief valve, and performing corrective actions if necessary. 
This AD results from reports that excess sealant was applied to the 
attachment bolts of the negative pressure relief valve, which 
interfered with the valve's movable diaphragm. We are issuing this AD 
to prevent incorrect operation of the negative pressure relief valve, 
which could result in negative pressures that exceed the structural 
strength limits of the airframe and lead to reduced structural 
integrity of the airplane.

DATES: This AD becomes effective July 25, 2006.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of July 25, 
2006.

SUPPLEMENTARY INFORMATION:

Examining the Docket

    You may examine the airworthiness directive (AD) docket on the 
Internet at http://dms.dot.gov or in person at the Docket Management 
Facility office between 9 a.m. and 5 p.m., Monday through Friday, 
except Federal holidays. The Docket Management Facility office 
(telephone (800) 647-5227) is located on the plaza level of the Nassif 
Building at the street address stated in the ADDRESSES section.

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that would apply to certain EMBRAER Model 
ERJ 170 airplanes. That NPRM was published in the Federal Register on 
April 21, 2006 (71 FR 20593). That NPRM proposed to require inspecting 
for excess sealant applied to the attachment bolts of the negative 
pressure relief valve, and performing corrective actions if necessary.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We received no

[[Page 35384]]

comments on the NPRM or on the determination of the cost to the public.

Clarification of Serial Number Range

    To clarify the range of the serial numbers of the affected 
airplanes we have added the word ``inclusive'' to the applicability of 
the AD.

Conclusion

    We have carefully reviewed the available data and determined that 
air safety and the public interest require adopting the AD with the 
change described previously. We have determined that this change will 
neither increase the economic burden on any operator nor increase the 
scope of the AD.

Costs of Compliance

    This AD will affect about 54 airplanes of U.S. registry. The 
required actions will take about 1 work hour per airplane, at an 
average labor rate of $80 per work hour. Based on these figures, the 
estimated cost of this AD for U.S. operators is $4,320, or $80 per 
airplane.

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 have 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 DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979); and
    (3) 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. See the ADDRESSES 
section for a location to examine the regulatory evaluation.
