**ACTION :**  Final rule.

**SUMMARY :**  We are adopting a new airworthiness directive (AD) for certain the Boeing Company Model 777–200, –200LR, and –300ER series airplanes. This AD was prompted by a report from the manufacturer indicating that the lowered ceiling support structure of Section 41, in airplanes incorporating the overhead space utilization (OSU) option, was found to be under-strength when subjected to a 9.0 g forward load. This AD requires installing new structural members, tie rod(s), and attach fittings on the left and right sides of the lowered ceiling support structure. We are issuing this AD to prevent the forward lowered ceiling panels and support structure from becoming dislodged during a 9.0 g forward load and consequent injury to personnel or interference with an emergency evacuation.

**DATES :**  This AD is effective July 30,
2012.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of July 30, 2012.

### 37794 Federal Register / Vol. 77, No. 122 / Monday, June 25, 2012 / Rules and Regulations

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM published in the Federal Register on November 30, 2011 (76 FR 74012). That NPRM proposed to require installing new structural members in and new tie rod(s) and attach fittings on the left and right sides of the lowered ceiling support structure.

Comments

We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the proposal (76 FR 74012, November 30, 2011) and the FAA’s response to each comment. Request to Include Latest Revision of Service Information

United Airlines, Air France, and Boeing requested that we revise the proposed rule (76 FR 74012, November 30, 2011) to reflect the latest revision of the service information in this AD.

We agree. Boeing has issued Boeing Special Attention Service Bulletin 777– 25–0482, Revision 1, dated February 21, 2012. This service bulletin was revised due to minor changes to correct hardware and location for its installation. We have changed this final rule to reference Boeing Special Attention Service Bulletin 777–25– 0482, Revision 1, dated February 21, 2012, and changed total task hours in the Costs of Compliance section of this AD from 19 hours to 23 hours to account for the revised labor hours. Paragraph (h) of this final rule has also been added to give credit for actions performed before the effective date of this AD using Boeing Special Attention Service Bulletin 777–25–0482, dated February 24, 2011.

Conclusion

We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting the AD with the changes described previously and minor editorial changes. We have determined that these minor changes:

• A re consistent with the intent that was proposed in the NPRM (76 FR 74012, November 30, 2011) for correcting the unsafe condition; and

• Do not add any additional burden upon the public than was already proposed in the NPRM (76 FR 74012, November 30, 2011).

We also determined that these changes will not increase the economic burden on any operator or increase the scope of the AD.
Costs of Compliance

We estimate that this AD affects 4 airplanes of U.S. registry.

We estimate the following costs to comply with this AD:



### E STIMATED 

### C OSTS

Action Labor cost Parts cost Cost per product Cost on U.S. operators

Install ceiling support structure members, fittings, and tie rods. 23 work-hours × $85 per hour = $1,955 ........ $13,329 $15,284 $61,136

According to the manufacturer, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. 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

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),

(3) Will not affect intrastate aviation in Alaska, and

(4) 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. List of Subjects in 14 CFR Part 39

**Airworthiness Directives; Dassault Aviation Airplanes** 

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

**ACTION :**  Final rule.

**SUMMARY :**  We are superseding an existing airworthiness directive (AD) for certain Dassault Aviation Model FALCON 7X airplanes. That AD currently requires revising the Abnormal Procedures and Limitations sections of the Dassault F7X Airplane Flight Manual. This new AD requires a test of the power distribution control units (PDCU) cards and generator control units (GCU) cards to detect faulty components, and if any faulty components are found, replacing any affected PDCU or GCU card. This AD was prompted by a determination that additional actions are necessary to address the identified unsafe condition. We are issuing this AD to detect and correct a leakage failure mode of transient voltage suppression (TVS) diodes used on PDCU cards or GCU cards in the primary power distribution boxes (PPDB), which, in combination with other system failures, could lead to loss of controllability of the airplane.

**DATES :**  This AD becomes effective July 30, 2012.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of July 30, 2012.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on March 15, 2012 (77 FR 15293), and proposed to supersede AD AD 2010–18–03, Amendment 39–16416 (75 FR 51931, August 24, 2010).

On August 11, 2010, we issued AD 2010–18–03, Amendment 39–16416 (75 FR 51931, August 24, 2010). That AD required actions intended to address an unsafe condition on certain Dassault Aviation Model FALCON 7X airplanes. The preamble of AD 2010–18–03 explains that we consider the requirements of that AD ‘‘interim action’’ and are considering further rulemaking to mandate inspection (testing) of the PDCU and GCU cards and replacement of faulty cards, as required by European Aviation Safety Agency AD 2010–0073, dated April 15,
