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.

Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES

2. The Federal Aviation Administration (FAA) amends Sec. 39.13 by
removing amendment 39-12585 (67 FR 265, January 3, 2002) and by adding
the following new airworthiness directive (AD):
[[Page 8719]]

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
