ACTION: Final rule. AGENCY: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A321 series airplanes. This AD requires repetitive measurements for correct control rod gap of the hold-open mechanism of all emergency doors, and corrective actions if necessary. This AD also requires replacing the control rods with new, improved control rods, which would terminate the repetitive measurements. This AD results from a report that an operator found it impossible to lock emergency doors 2 and 3 in the open position. We are issuing this AD to prevent failure of the emergency doors to lock in the open position, which could interfere with passenger evacuation during an emergency. DATES: Effective September 27, 2005. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of September 27, 2005.

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 Airbus Model A321 series airplanes. That NPRM was published in the Federal Register on June 3, 2005 (70 FR 32542). That NPRM proposed to require repetitive measurements for correct control rod gap of the hold-open mechanism of all emergency doors, and corrective actions if necessary. The NPRM also proposed to require replacing the control rods with new, improved control rods, which would terminate the repetitive measurements. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comment that has been received on the NPRM. Support for the Proposed AD The commenter supports the NPRM. Explanation of Change to Applicability We have revised the applicability of the NPRM to identify model designations as published in the most recent type certificate data sheet for the affected models. Conclusion We have carefully reviewed the available data, including the comment 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. PO 00000 Frm 00017 Fmt 4700 Sfmt 4700 49169 Costs of Compliance This AD will affect about 28 airplanes of U.S. registry. The measurement to determine control rod gap will take about 2 work hours per airplane, at an average labor rate of $65 per work hour. Based on these figures, the estimated cost of the measurement for U.S. operators is $3,640, or $130 per airplane, per measurement cycle. The replacement of the control rods with new, improved, water-resistant control rods will take about 9 work hours per airplane, at an average labor rate of $65 per work hour. Required parts will cost about $400 per airplane. Based on these figures, the estimated cost of the required replacement for U.S. operators is $27,580, or $985 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.

Airworthiness Directives; Airbus Model A321 Series Airplanes

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

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Airbus Model A321 series airplanes. This AD requires repetitive 
measurements for correct control rod gap of the hold-open mechanism of 
all emergency doors, and corrective actions if necessary. This AD also 
requires replacing the control rods with new, improved control rods, 
which would terminate the repetitive measurements. This AD results from 
a report that an operator found it impossible to lock emergency doors 2 
and 3 in the open position. We are issuing this AD to prevent failure 
of the emergency doors to lock in the open position, which could 
interfere with passenger evacuation during an emergency.

DATES: Effective September 27, 2005.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of September 27, 
2005.

ADDRESSES: You may examine the AD docket on the Internet at https://

SUPPLEMENTARY INFORMATION: 

Examining the Docket

    You may examine the AD docket on the Internet at https://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 Airbus Model 
A321 series airplanes. That NPRM was published in the Federal Register 
on June 3, 2005 (70 FR 32542). That NPRM proposed to require repetitive 
measurements for correct control rod gap of the hold-open mechanism of 
all emergency doors, and corrective actions if necessary. The NPRM also 
proposed to require replacing the control rods with new, improved 
control rods, which would terminate the repetitive measurements.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comment that has been 
received on the NPRM.

Support for the Proposed AD

    The commenter supports the NPRM.

Explanation of Change to Applicability

    We have revised the applicability of the NPRM to identify model 
designations as published in the most recent type certificate data 
sheet for the affected models.

Conclusion

    We have carefully reviewed the available data, including the 
comment 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

    This AD will affect about 28 airplanes of U.S. registry.
    The measurement to determine control rod gap will take about 2 work 
hours per airplane, at an average labor rate of $65 per work hour. 
Based on these figures, the estimated cost of the measurement for U.S. 
operators is $3,640, or $130 per airplane, per measurement cycle.
    The replacement of the control rods with new, improved, water-
resistant control rods will take about 9 work hours per airplane, at an 
average labor rate of $65 per work hour. Required parts will cost about 
$400 per airplane. Based on these figures, the estimated cost of the 
required replacement for U.S. operators is $27,580, or $985 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.
