ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737–200 and –200C series airplanes. This AD was prompted by a report of elevator vibration and bearing swage failures. This AD requires, for certain airplanes, repetitive inspections for any discrepancies (such as a gap or a loose spacer) of the aft attach lugs for the elevator tab control mechanism, and replacement if necessary; and, for other airplanes, contacting the FAA for inspection or repair instructions and doing the work specified in those instructions. We are issuing this AD to detect and correct discrepancies in the SUMMARY: aft attach lugs for the elevator tab control mechanism, which could result in elevator and tab vibration. Consequent structural failure of the elevator or horizontal stabilizer could result in loss of structural integrity and loss of airplane control. DATES: This AD is effective November 21, 2012.

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 published in the Federal Register on August 1, 2012 (77 FR 45513). That NPRM proposed to require, for certain airplanes, repetitive inspections for any discrepancies (such as a gap or a loose spacer) of the aft attach lugs for the elevator tab control mechanism, and replacement if necessary; and, for other airplanes, contacting the FAA for inspection or repair instructions and doing the work specified in those instructions. Comments We gave the public the opportunity to participate in developing this AD. We have considered the comment received. Boeing supports the NPRM (77 FR 45513, August 1, 2012). 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 NPRM (77 FR 45513, August 1, 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 45513, August 1, 2012). Costs of Compliance We estimate that this AD affects 200 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Action erowe on DSK2VPTVN1PROD with Inspection for Group 2 airplanes. Labor cost 7 work-hours × $85 per hour = $595 per inspection cycle.

That AD currently requires revising the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness to incorporate new limitations for fuel tank systems. This new AD requires revising the maintenance program to incorporate revised fuel maintenance and inspection tasks, and adds airplanes to the applicability. This AD was prompted by Airbus issuing more restrictive maintenance requirements and/or airworthiness limitations. We are issuing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.

The Fuel Airworthiness Limitations (FAL) are specified in Airbus A318/A319/A320/ A321 FAL Document reference 95A.1931/05, which is approved by the European Aviation Safety Agency (EASA) and referenced in the Airbus A318/A319/A320/A321 ALS Part 5. The issue 4 of Airbus A318/A319/A320/ A321 FAL Document introduces more restrictive maintenance requirements and/or airworthiness limitations. Failure to comply with these more restrictive maintenance requirements and airworthiness limitations contained in this document constitutes an unsafe condition. This [EASA] AD retains the requirement of EASA AD 2006–0203, which is superseded, and requires the implementation of the new or more restrictive maintenance requirements and/or airworthiness limitations as specified in Airbus A318/A319/A320/A321 FAL Document issue 4.

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 737-200 and -200C series airplanes. This AD 
was prompted by a report of elevator vibration and bearing swage 
failures. This AD requires, for certain airplanes, repetitive 
inspections for any discrepancies (such as a gap or a loose spacer) of 
the aft attach lugs for the elevator tab control mechanism, and 
replacement if necessary; and, for other airplanes, contacting the FAA 
for inspection or repair instructions and doing the work specified in 
those instructions. We are issuing this AD to detect and correct 
discrepancies in the aft attach lugs for the elevator tab control 
mechanism, which could result in elevator and tab vibration. Consequent 
structural failure of the elevator or horizontal stabilizer could 
result in loss of structural integrity and loss of airplane control.

DATES: This AD is effective November 21, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of November 21, 
2012.

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 published in the Federal Register on August 1, 2012 (77 FR 
45513). That NPRM proposed to require, for certain airplanes, 
repetitive inspections for any discrepancies (such as a gap or a loose 
spacer) of the aft attach lugs for the elevator tab control mechanism, 
and replacement if necessary; and, for other airplanes, contacting the 
FAA for inspection or repair instructions and doing the work specified 
in those instructions.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We have considered the comment received. Boeing supports the 
NPRM (77 FR 45513, August 1, 2012).

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 
NPRM (77 FR 45513, August 1, 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 45513, August 1, 2012).

Costs of Compliance

    We estimate that this AD affects 200 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

    For Group 1 airplanes, we do not have definitive data that would 
enable us to provide cost estimates for the action specified in this 
AD.
    We estimate the following costs to do any necessary replacements 
that would be required based on the results of the inspection. We have 
no way of determining the number of aircraft that might need these 
replacements:

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

    This AD was prompted by a report of elevator vibration and 
bearing swage failures. We are issuing this AD to detect and correct 
discrepancies in the aft attach lugs for the elevator tab control 
mechanism, which could result in elevator and tab vibration. 
Consequent structural failure of the elevator or horizontal 
stabilizer could result in loss of structural integrity and loss of 
airplane control.

cycles or 2,000 flight hours after the effective date of this AD, 
whichever occurs first, inspect the left and right elevator tab 
control mechanisms, and repair or replace as applicable, in 
accordance with a method approved by the Manager, Seattle Aircraft 
Certification Office (ACO), FAA. For a repair method to be approved, 
the repair must meet the certification basis of the airplane, and 
the approval must specifically refer to this AD.

(h) Inspection for Group 2 Airplanes

    For Group 2 airplanes as identified in Boeing Alert Service 
Bulletin 737-27A1302, dated April 24, 2012: Within 1,500 flight
