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

ACTION: Final rule.

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

SUMMARY: The FAA is superseding two existing airworthiness directives 
(AD), which apply to certain Boeing airplanes as specified above. Those 
ADs currently require inspection of the attachment of the shoulder 
restraint harness to the mounting bracket on certain observer and 
attendant seats to determine if a C-clip is used in the attachment, and 
corrective action if necessary. This new AD removes certain airplanes 
from the applicability of one existing AD and adds other airplanes. We 
also determined that this new AD refers to identical revisions of 
certain service information cited by another existing AD. This AD 
results from the determination that some airplanes had been 
inadvertently included in or excluded from the applicability of one 
existing AD and that certain additional new airplanes are now subject 
to the identified unsafe condition. We are issuing this AD to prevent 
detachment of the shoulder restraint harness of the attendant or 
observer seat from its mounting bracket during service, which could 
result in injury to the occupant of the seat.

DATES: This AD becomes effective February 12, 2007.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of February 12, 
2007.
    On October 21, 2003 (68 FR 57609, October 6, 2003), the Director of 
the Federal Register approved the incorporation by reference of certain 
other publications listed in the AD.
    On January 4, 2002 (66 FR 59681, November 30, 2001), the Director 
of the Federal Register approved the incorporation by reference of 
certain other publications listed in the AD.

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that supersedes AD 2001-24-02, amendment 
39-12518 (66 FR 59681, November 30, 2001). The existing AD applies to 
certain Boeing Model 707-100, -100B, -300, and -E3A (military 
airplanes); 727-100 and -200; 737-200, -200C, -300, -400, and -500; 
747SP and 747SR; 747-100B, -200B, -200C, -200F, -300, -400, and -400D; 
757-200 and -200PF; and 767-200 and -300 series airplanes. That NPRM 
was published in the Federal Register on June 8, 2006 (71 FR 33267). 
That NPRM proposed to continue to require an inspection of the 
attachment of the shoulder restraint harness to the mounting bracket on 
certain observer and attendant seats to determine if a C-clip is used 
in the attachment, and corrective action, if necessary. That NPRM also 
proposed to remove certain airplanes from the applicability of the 
existing AD and add others.
    Since we issued that NPRM, we were made aware that another AD 
should be affected by the proposed action. AD 2003-20-08, amendment 39-
13326 (68 FR 57609, October 6, 2003), was issued to correct the same 
unsafe condition on certain Boeing Model 747-100B, -200B, -200C, -200F, 
-300, -400, -400D, 747SP, and 747SR series airplanes, and Model 767-200 
and -300 series airplanes, not addressed by AD 2001-24-02. As this new 
AD cites certain primary sources of service information that are 
already cited in AD 2003-20-08, we determined that this could lead to 
confusion regarding applicability and unnecessary extra recordkeeping. 
Therefore, we also determined that this AD should be revised to 
supersede AD 2003-20-08 as well as AD 2001-24-02. Because none of the 
airplanes affected by AD 2003-20-08 appear on the U.S. Register, the 
requirements and costs to operators described in the NPRM will not 
change; therefore, we determined that providing additional notice and 
opportunity for public comment is unnecessary before this AD is issued.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comments that have been 
received on the NPRM.

Support for the NPRM

    Boeing concurs with the contents of the NPRM.

Recommendation for Reference to Additional AD

    United Airlines (UAL) and United Parcel Service (UPS) recommend a 
reference to an additional existing AD. UAL and UPS state that AD 2003-
20-08 addresses exactly the same problem on Boeing Model 747 and 767 
airplanes. UPS and UAL recommend that the NPRM refer to both AD 2001-
24-02 and AD 2003-20-08.
    We agree. Further, as discussed earlier, we have determined that 
this AD should not only refer to AD 2003-20-08, it should supersede 
that AD. AD 2001-24-02 refers to Boeing Service Bulletins 747-25-3244 
and 767-25-0288, both at Revision 1, both dated May 17, 2001, as 
primary sources of service information, while AD 2003-20-08 refers to 
Boeing Service Bulletin 747-25-3244, Revision 4, dated June 26, 2003, 
and Boeing Special Attention Service Bulletin 767-25-0288, Revision 3, 
dated August 1, 2002, as primary sources of service information. No 
conflict exists between those references.

[[Page 648]]

However, this AD also refers to Boeing Service Bulletin 747-25-3244, 
Revision 4, dated June 26, 2003; and Boeing Special Attention Service 
Bulletin 767-25-0288, Revision 3, dated August 1, 2002, as primary 
sources of service information. Two existing ADs that refer to 
identical service information to require identical actions could lead 
to confusion regarding applicability and unnecessary extra 
recordkeeping. As revising this AD to supersede AD 2003-20-08 will not 
add any requirements to this AD or increase costs to operators, we have 
determined that additional time for comments is unnecessary. Therefore, 
to eliminate parallel rulemaking and reduce the workload to operators 
and the FAA, we have revised this AD to supersede AD 2003-20-08 as well 
as AD 2001-24-02. As part of this revision, we have added a new Table 2 
in paragraph (f) of this AD to address the applicability of AD 2001-24-
02, and re-identified the existing Table 2 and all subsequent tables in 
the AD.

Request To Approve Existing Alternative Methods of Compliance (AMOCs)

    UAL, UPS, and ABX Air (ABX) request that previously granted AMOCs 
with AD 2001-24-02 be approved for use with this AD. UAL is of the 
opinion that these previously granted AMOCs should also be valid for 
use under this new ruling. ABX relates that it went through the AMOC 
process for AD 2001-24-02 and requests that the following statement be 
added to the NPRM: ``AMOCs approved previously per AD 2001-24-02, 
amendment 39-12518, are approved as AMOCs with the applicable actions 
in paragraph (f) of this AD.'' UPS states that although this AD retains 
the requirements of AD 2001-24-02, this AD does not address the 
approved AMOCs to AD 2001-24-02. UPS asserts that all airplanes 
affected by AD 2001-24-02 would have been inspected within 36 months 
after January 4, 2002 (the effective date of AD 2001-24-02), or would 
be operating under an AMOC approved for use with AD 2001-24-02. UPS 
asserts that, if this AD supersedes AD 2001-24-02 without permitting 
use of the previously approved AMOCs, airplanes would be grounded 
immediately as of the effective date of this AD.
    We agree. The only changes to this AD affect airplane 
applicability; therefore, all previously granted AMOCs are still valid. 
Further, we have determined that approved AMOCs with AD 2003-20-08 are 
still valid as well. Therefore, we have revised paragraph (m) of this 
AD to state that previously approved AMOCs with AD 2001-24-02 and AD 
2003-20-08 are valid for use with this AD.

Request To Exempt Freighter Airplanes

    UPS requests that airplanes which have been configured to carry 
freight be exempted from the applicability of this AD. UPS states that 
freighter airplanes no longer have the noted observer or attendant 
seats installed.
    We agree that the specified seats are not currently installed on 
freighter airplanes, the specified C-clips are not present, and, as 
paragraph (c) of the AD states, the AD applies only to airplanes with 
observer or attendant seats installed. However, should such a seat be 
installed on a freighter airplane for any reason, that airplane would 
be subject to the requirements of this AD. Therefore, no change is 
needed to the AD in this regard.

Request To Revise Applicability

    UPS requests that we revise the applicability of the NPRM. UPS 
asserts that, because the compliance time of AD 2001-24-02 has passed, 
all airplanes specified by that AD must be in compliance and this rule 
is not necessary for those airplanes. UPS requests that we make this AD 
applicable only to new airplanes instead of superseding AD 2001-24-02.
    We do not agree. We have determined that the new AD is necessary to 
accurately reflect all applicable airplanes, to ensure that operators 
outside the U.S. are made aware of the AD requirements, and to ensure 
that any airplane imported into the country and placed on the U.S. 
Register is subject to the requirements of this AD. We have not changed 
the AD in this regard.

Conclusion

    We have carefully reviewed the available data, including the 
comments that have been received, and determined that air safety and 
the public interest require adopting the AD with the changes described 
previously. We have determined that these changes will neither increase 
the economic burden on any operator nor increase the scope of the AD.

Costs of Compliance

    Since we issued AD 2001-24-02 and AD 2003-20-08, we have increased 
the labor rate used in the cost estimate calculations to $80 per work 
hour. However, with respect to the total cost impact for the fleet, 
this increase in the hourly labor rate will be offset by the decrease 
in the number of affected airplanes in this AD. Further, none of the 
additional airplanes affected by AD 2003-20-08 appear on the U.S. 
Registry; therefore, no additional costs apply to U.S. operators.
    The following table provides the estimated costs for U.S. operators 
to comply with this AD.

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

[[Page 649]]

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.
