Airworthiness Directives; Boeing Model 767-200, -300, and -400ER 
Series Airplanes

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

ACTION: Final rule.

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

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD),

[[Page 8718]]

which applies to certain Boeing Model 767 series airplanes. That AD 
currently requires a one-time inspection for missing, damaged, or 
incorrectly installed parts in the separation link assembly on the 
deployment bar of the emergency escape system on the entry or service 
door, and installation of new parts if necessary. This new AD requires 
replacing the separation link assembly on the applicable entry and 
service doors with an improved separation link assembly, and doing 
related investigative and corrective actions if necessary; and 
inspecting for discrepancies of the unloaded spring dimensions in the 
separation link assembly, and doing corrective actions if necessary. 
This AD also removes certain airplanes from the applicability. This AD 
results from reports that entry and service doors did not open fully 
during deployment of emergency escape slides, and additional reports of 
missing snap rings. We are issuing this AD to prevent failure of an 
entry or service door to open fully in the event of an emergency 
evacuation, which could impede exit from the airplane. This condition 
could result in injury to passengers or crewmembers.

DATES: This AD becomes effective April 2, 2009.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of April 2, 2009.

SUPPLEMENTARY INFORMATION:

Discussion

    The FAA issued a supplemental notice of proposed rulemaking (NPRM) 
to amend 14 CFR part 39 to include an AD that supersedes AD 2001-26-19, 
amendment 39-12585 (67 FR 265, January 3, 2002). The existing AD 
applies to certain Boeing Model 767 series airplanes. That supplemental 
NPRM was published in the Federal Register on September 23, 2008 (73 FR 
54747). That supplemental NPRM proposed to require replacing the 
separation link assembly on the applicable entry and service doors with 
an improved separation link assembly, and doing related investigative 
and corrective actions if necessary; and inspecting for discrepancies 
of the unloaded spring dimensions in the separation link assembly, and 
doing corrective actions if necessary. That supplemental NPRM also 
proposed to remove certain airplanes from the applicability.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. No comments have been received on the 
supplemental NPRM or on the determination of the cost to the public.

Conclusion

    We have carefully reviewed the available data and determined that 
air safety and the public interest require adopting the AD as proposed 
in the supplemental NPRM.

Costs of Compliance

    There are about 1,225 airplanes of the affected design in the 
worldwide fleet. This AD affects about 355 airplanes of U.S. registry. 
The new actions take up to about 6 work hours per airplane, at an 
average labor rate of $80 per work hour. Required parts cost up to 
about $10,671 per airplane. Based on these figures, the estimated cost 
of the new actions specified in this AD for U.S. operators is 
$3,958,605, or $11,151 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.

emergency escape system on all the applicable entry and service 
doors with an improved separation link assembly, and do all the 
applicable related investigative and corrective actions before 
further flight, by accomplishing all of the applicable actions 
specified in the Accomplishment Instructions of Boeing Special 
Attention Service Bulletin 767-25-0428, dated August 23, 2007; or 
Revision 1, dated May 8, 2008. After the effective date of this AD 
only Boeing Special Attention Service Bulletin 767-25-0428, Revision 
1, may be used.
