SUPPLEMENTARY INFORMATION: Discussion We issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 to include an airworthiness directive (AD) that would apply to the specified products. That SNPRM published in the Federal Register on August 31, 2012 (77 FR 53155). The original NPRM (76 FR 69159, November 8, 2011) proposed to require checking the escape slide girt for serviceability, and replacement if necessary; modifying the cable routing provision; replacing the regulator padding; modifying the aspirator orientation; and modifying the valise. PO 00000 Frm 00016 Fmt 4700 Sfmt 4700 The original NPRM also proposed to require, for certain airplanes, modifying or replacing the Vespel piston, modifying the pilot valve regulator, installing a new firing cable and safety pin, and modifying the slide valise. The SNPRM proposed to add airplanes to the applicability of the original NPRM, and specify revised service information. For certain other airplanes, this AD requires an additional modification of the escape slide. Comments We gave the public the opportunity to participate in developing this AD. We have considered the comments received. Support for the SNPRM (77 FR 53155, August 31, 2012) Boeing stated that it concurs with the contents of the SNPRM (77 FR 53155, August 31, 2012), and therefore, no additional comments will be forthcoming. Goodrich Corporation stated that the comments it submitted to the original NPRM (76 FR 69159, November 8, 2011) have been satisfactorily addressed, and therefore, it has no additional comments or changes to offer. 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–except for minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the SNPRM (77 FR 53155, August 31, 2012) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the SNPRM (77 FR 53155, August 31, 2012). Additional Change Made to This Final Rule We have removed the girt replacement on-condition cost specified in the SNPRM (77 FR 53155, August 31, 2012) from this AD, because the proposed girt check for continued serviceability was removed from the SNPRM and is not included in this AD. Costs of Compliance We estimate that this AD affects 557 airplanes of U.S. registry.

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. pmangrum on DSK3VPTVN1PROD with According to the parts supplier, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: 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 responsibilities among the various levels of government.

Since we issued AD 2012–18–10, Amendment 39–17187 (77 FR 55686, September 11, 2012), the Civil Aviation Safety Authority (CASA), which is the aviation authority for the Commonwealth of Australia, has issued AD AD/GA200/1, Amendment 1, dated September 21, 2012 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The NPRM proposed to correct an unsafe condition for the specified products. The MCAI states that: As a result of a reported case of failure of a strut on a GA200C aircraft, GippsAero has issued a mandatory service bulletin to alert operators and maintenance organisations and to provide inspection and rectification actions. This Airworthiness Directive makes this inspection and rectification action mandatory. Failure to complete the actions required by this service bulletin may result in wing strut bolt failure, resulting in wing structural failure. Amendment 1 is issued to revise the repeat inspection compliance time to 500 hours (previously 100 hours). The requirement service bulletin is also revised to provide a corrective action if the inboard (upper) strut fitting hole is found to be larger than specified. The initial inspection compliance time of 10 hours remains unchanged. This AD retains the actions required in AD 2012–18–10, Amendment 39– 17187 (77 FR 55686, September 11, 2012), changes the compliance time for the repetitive inspections from intervals of 100 hours time-in-service (TIS) to intervals of 500 hours TIS, and incorporates the revised service bulletin that includes repair instructions in lieu E:\FR\FM\27DER1.SGM 27DER1

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 737-600, -700, -700C, -800, -900, and -900ER 
series airplanes. This AD was prompted by reports of escape slides 
failing to deploy from the forward and aft right-hand doors during 
scheduled maintenance slide deployments. This AD requires modifying the 
escape slide. Also, for certain airplanes, this AD requires modifying 
or replacing the Vespel piston. For certain other airplanes, this AD 
requires an additional modification of the escape slide. We are issuing 
this AD to prevent failure of an escape slide to deploy, which could 
result in the slide being unusable during an emergency evacuation and 
increased likelihood of injury to passengers or crewmembers due to the 
difficulty in evacuating the airplane.

DATES: This AD is effective January 31, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of January 31, 
2013.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a supplemental notice of proposed rulemaking (SNPRM) to 
amend 14 CFR part 39 to include an airworthiness directive (AD) that 
would apply to the specified products. That SNPRM published in the 
Federal Register on August 31, 2012 (77 FR 53155). The original NPRM 
(76 FR 69159, November 8, 2011) proposed to require checking the escape 
slide girt for serviceability, and replacement if necessary; modifying 
the cable routing provision; replacing the regulator padding; modifying 
the aspirator orientation; and modifying the valise. The original NPRM 
also proposed to require, for certain airplanes, modifying or replacing 
the Vespel piston, modifying the pilot valve regulator, installing a 
new firing cable and safety pin, and modifying the slide valise. The 
SNPRM proposed to add airplanes to the applicability of the original 
NPRM, and specify revised service information. For certain other 
airplanes, this AD requires an additional modification of the escape 
slide.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We have considered the comments received.

Support for the SNPRM (77 FR 53155, August 31, 2012)

    Boeing stated that it concurs with the contents of the SNPRM (77 FR 
53155, August 31, 2012), and therefore, no additional comments will be 
forthcoming.
    Goodrich Corporation stated that the comments it submitted to the 
original NPRM (76 FR 69159, November 8, 2011) have been satisfactorily 
addressed, and therefore, it has no additional comments or changes to 
offer.

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-except for minor editorial changes. We have 
determined that these minor changes:
     Are consistent with the intent that was proposed in the 
SNPRM (77 FR 53155, August 31, 2012) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the SNPRM (77 FR 53155, August 31, 2012).

Additional Change Made to This Final Rule

    We have removed the girt replacement on-condition cost specified in 
the SNPRM (77 FR 53155, August 31, 2012) from this AD, because the 
proposed girt check for continued serviceability was removed from the 
SNPRM and is not included in this AD.

Costs of Compliance

    We estimate that this AD affects 557 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

    According to the parts supplier, some of the costs of this AD may 
be covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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 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),
    (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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2012-25-05 The Boeing Company: Amendment 39-17286; Docket No. FAA-
2011-1222; Directorate Identifier 2010-NM-268-AD.

(a) Effective Date

    This AD is effective January 31, 2013.

(b) Affected ADs

    This AD affects AD 2008-24-08, Amendment 39-15748 (73 FR 72320, 
November 28, 2008).

(c) Applicability

    This AD applies to The Boeing Company Model 737-600, -700, -
700C, -800, -900, and -900ER series airplanes, certificated in any 
category, with Goodrich Corporation door escape slide part number 
(P/N) 5A3307-1, -3, -5, or -301, serial numbers (S/N) BNG0001

(d) Subject

    Joint Aircraft System Component (JASC)/Air Transport Association 
(ATA) of America Code 25, Equipment/Furnishings.

(e) Unsafe Condition

    This AD was prompted by reports of escape slides failing to 
deploy from the forward and aft right-hand doors during scheduled 
maintenance slide deployments. We are issuing this AD to prevent 
failure of an escape slide to deploy, which could result in the 
slide being unusable during an emergency evacuation and increased 
likelihood of injury to passengers or crewmembers due to the 
difficulty in evacuating the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Slide Modification

    Within 36 months after the effective date of this AD: Modify the
