ACTION: Final rule. SUMMARY: We are adopting a new airworthiness directive (AD) for certain Boeing Model 737–100, –200, –200C, –300, –400, and –500 series airplanes. This AD requires repetitive detailed and high frequency eddy current inspections to detect cracks of the backup intercostals and the upper sill of the forward airstair doorway, and applicable corrective actions. This AD also provides for an optional terminating action, which would eliminate the need for repetitive inspections. This AD results from a report indicating that cracks were found in the backup intercostals and upper sill web of the forward airstair doorway. We are issuing this AD to detect and correct fatigue cracking of the backup intercostals and upper sill web of the forward airstair doorway, which could result in a rapid loss of cabin pressure. DATES: This AD is effective June 11, 2009. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of June 11, 2009.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an airworthiness directive (AD) that would apply to certain Boeing Model 737–100, –200, –200C, –300, –400, and –500 series airplanes. That NPRM was published in the Federal Register on December 5, 2008 (73 FR 74080). That NPRM proposed to require repetitive detailed and high frequency eddy current inspections to detect cracks of the backup intercostals and the upper sill of the forward airstair doorway, and applicable corrective actions. That NPRM also provided an optional terminating action, which would eliminate the need for repetitive inspections. Comments We gave the public the opportunity to participate in developing this AD. We considered the comments received from the two commenters. Support for the NPRM Boeing concurs with the contents of the NPRM. Request for Clarification Southwest Airlines requests more information regarding alternative procedures for airplanes that have had the airstair door deactivated per Boeing Service Bulletin 737–52–1092. Southwest Airlines asks whether instructions developed by operators, for open and close of an airstair door after deactivation per Boeing Service Bulletin 737–52–1092, will be considered approved equivalent procedures. No alternative procedures have been established that have general FAA approval; however, according to the PO 00000 Frm 00010 Fmt 4700 Sfmt 4700 provisions of paragraph (h) of the final rule we may approve requests for different compliance methods if the requests include data that prove that the new methods would provide an acceptable level of safety. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance There are 1,712 airplanes of the affected design in the worldwide fleet. This AD affects 509 airplanes of U.S. registry. The inspections take 2 work hours per airplane, at an average labor rate of $80 per work hour. Based on these figures, the estimated cost of the AD for U.S. operators is $81,440, or $160 per airplane, per inspection cycle. The optional terminating action, if done, would take 9 work hours, at an average labor rate of $80 per work hour. Required parts cost between $533 and $566 per airplane, depending on the airplane configuration. Based on these figures, the estimated cost of the optional terminating action would range between $1,253 and $1,286 per airplane, depending on the airplane configuration. 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 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 E:\FR\FM\07MYR1.SGM 07MYR1 Federal Register / Vol. 74, No. 87 / Thursday, May 7, 2009 / Rules and Regulations responsibilities among the various levels of government.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an airworthiness directive (AD) that would apply to 
certain Boeing Model 737-100, -200, -200C, -300, -400, and -500 series 
airplanes. That NPRM was published in the Federal Register on December 
5, 2008 (73 FR 74080). That NPRM proposed to require repetitive 
detailed and high frequency eddy current inspections to detect cracks 
of the backup intercostals and the upper sill of the forward airstair 
doorway, and applicable corrective actions. That NPRM also provided an 
optional terminating action, which would eliminate the need for 
repetitive inspections.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comments received from the two commenters.

Support for the NPRM

    Boeing concurs with the contents of the NPRM.

Request for Clarification

    Southwest Airlines requests more information regarding alternative 
procedures for airplanes that have had the airstair door deactivated 
per Boeing Service Bulletin 737-52-1092. Southwest Airlines asks 
whether instructions developed by operators, for open and close of an 
airstair door after deactivation per Boeing Service Bulletin 737-52-
1092, will be considered approved equivalent procedures.
    No alternative procedures have been established that have general 
FAA approval; however, according to the provisions of paragraph (h) of 
the final rule we may approve requests for different compliance methods 
if the requests include data that prove that the new methods would 
provide an acceptable level of safety.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
the AD as proposed.

Costs of Compliance

    There are 1,712 airplanes of the affected design in the worldwide 
fleet. This AD affects 509 airplanes of U.S. registry. The inspections 
take 2 work hours per airplane, at an average labor rate of $80 per 
work hour. Based on these figures, the estimated cost of the AD for 
U.S. operators is $81,440, or $160 per airplane, per inspection cycle.
    The optional terminating action, if done, would take 9 work hours, 
at an average labor rate of $80 per work hour. Required parts cost 
between $533 and $566 per airplane, depending on the airplane 
configuration. Based on these figures, the estimated cost of the 
optional terminating action would range between $1,253 and $1,286 per 
airplane, depending on the airplane configuration.

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

    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

[[Page 21255]]

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.
    You can find our regulatory evaluation and the estimated costs of 
compliance in the AD Docket.
