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. 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.

Estimated Costs

Base model	Number of work hours (@ 1/4-work hour/seat)	Hourly labor rate	Total cost per airplane	Number of airplanes/U.S. registry	Total fleet cost	Number of airplanes/worldwide
707	1	$80	$80	21	$1,680	250
727	1	80	80	881	70,480	1,986
737	2	80	160	459	73,440	885

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.
