## Summary

The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 777-200 and -300 series airplanes. This AD requires inspecting for the installation of the tie plate for the wire bundles routed from lower section 41 into the center control stand in the flight deck; inspecting for any wire chafing or damage and repair if necessary; and installing a tie plate if necessary. This AD is prompted by a report of missing tie plates for the wire bundles. We are issuing this AD to prevent wire chafing, which could result in the loss of flight control, communication, navigation, and engine fire control systems. Loss of these systems could consequently result in a significant reduction of safety margins, an increase in flight crew workload, and in the case where loss of engine fire control is combined with an engine fire, could result in an uncontrollable fire.

## The airworthiness directive

### Adoption of the Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:

1. The authority citation for part 39 continues to read as follows:

2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD):

2005-13-29 Boeing: Amendment 39-14166. Docket No. FAA-2005-20660; Directorate Identifier 2004-NM-242-AD.

### (a) Effective Date

  (a) This AD becomes effective August 1, 2005.

### (b) Affected ADs

  (b) None.

### (c) Applicability

  (c) This AD applies to Boeing Model 777-200 and -300 series airplanes, certificated in any category; as identified in Boeing Alert Service Bulletin 777-27A0060, dated September 18, 2003.

### (d) Unsafe Condition

  (d) This AD was prompted by a report of missing tie plates for wire bundles that are routed from lower section 41 into the center control stand in the flight deck. We are issuing this AD to prevent wire chafing, which could result in the loss of flight control, communication, navigation, and engine fire control systems. Loss of these systems could consequently result in a significant reduction of safety margins, an increase in flight crew workload, and in the case where loss of engine fire control is combined with an engine fire, could result in an uncontrollable fire.

### (e) Compliance

  (e) You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.

### (f) Inspection

  (f) Within 18 months after the effective date of this AD, inspect for installation of the tie plate for the wire bundles routed from lower section 41 into the center control stand in the flight deck, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin 777-27A0060, dated September 18, 2003.

  (1) If the tie plate is found to be installed, no further action is required by this AD.

  (2) If the tie plate is missing, before further flight, do a detailed inspection of the wire bundles for any chafing or damage and repair if necessary, and install a tie plate in accordance with the Accomplishment Instructions of the service bulletin.

Note 1:

For the purposes of this AD, a detailed inspection is: “An intensive examination of a specific item, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at an intensity deemed appropriate. Inspection aids such as mirror, magnifying lenses, etc., may be necessary. Surface cleaning and elaborate procedures may be required.”

### (g) Alternative Methods of Compliance (AMOCs)

  (g) The Manager, Seattle Aircraft Certification Office, FAA, has the authority to approve AMOCs for this AD, if requested in accordance with the procedures found in 14 CFR 39.19.

### (h) Material Incorporated by Reference

  (h) You must use Boeing Alert Service Bulletin 777-27A0060, dated September 18, 2003, to perform the actions that are required by this AD, unless the AD specifies otherwise. The Director of the Federal Register approves the incorporation by reference of this document in accordance with 5 U.S.C. 552(a) and 1 CFR part 51.

### SUPPLEMENTARY INFORMATION

The FAA proposed to amend 14 CFR part 39 with an AD for certain Boeing Model 777-200 and -300 series airplanes. That action, published in the Federal Register on March 22, 2005 (70 FR 14430), proposed to require inspecting for the installation of the tie plate for the wire bundles routed from lower section 41 into the center control stand in the flight deck; inspecting for any wire chafing or damage and repair if necessary; and installing a tie plate if necessary.

### Comment

We provided the public the opportunity to participate in the development of this AD. We have considered the comment that has been submitted on the proposed AD. The commenter supports the proposed AD.

### Conclusion

We have carefully reviewed the available data, including the comment that has been submitted, and determined that air safety and the public interest require adopting the AD as proposed.

### Costs of Compliance

There are about 289 airplanes of the affected design in the worldwide fleet. The following table provides the estimated costs for U.S. operators to comply with this AD.

*Estimated Costs*

| Action | Work hour | Average labor rate per hour | Parts | Cost per airplane | Number of U.S.-registered airplanes | Fleet cost |
| --- | --- | --- | --- | --- | --- | --- |
| Inspection | 1 | $65 | $9 | $74 | 130 | $9,620 |

### 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. See the ADDRESSES section for a location to examine the regulatory evaluation.
