**SUMMARY :**  We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 777– 200LR, –300, –300ER, and 777F series airplanes. This AD was prompted by reports of dual pitch rate sensor (PRS) failures causing the primary flight computers to transition from primary mode to secondary mode, resulting in autopilot disconnects. This AD requires an inspection to determine the PRS part number, and replacement if necessary. We are issuing this AD to prevent a dual PRS failure that could cause an automatic disengagement of the autopilot and autoland, which may prevent continued safe flight and landing if disengagement occurs at low altitude and the flight crew is unable tosafely assume control and execute a goaround or manual landing. **DATES :**  This AD is effective December 26, 2014.

**SUPPLEMENTARY INFORMATION :** 

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain the Boeing Company Model 777 airplanes. The NPRM published in the Federal Register on April 25, 2014 (79 FR 22908). The NPRM was prompted by reports of dual PRS failures, resulting in autopilot disconnects. The NPRM proposed to require an inspection to determine the PRS part number, and replacement if necessary. We are issuing this AD to prevent a dual PRS failure that could cause an automatic disengagement of the autopilot and autoland, which may prevent continued safe flight and


### 69036 Federal Register / Vol. 79, No. 224 / Thursday, November 20, 2014 / Rules and Regulations

landing if disengagement occurs at low altitude and the flight crew is unable tosafely assume control and execute a goaround or manual landing.

Comments

We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM (79 FR 22908, April 25, 2014), and the FAA’s response to each comment. Support for the NPRM (79 FR 22908, April 25, 2014)

Boeing stated that it concurs with the contents of the NPRM (79 FR 22908, April 25, 2014). Request To Revise Alternative Method of Compliance (AMOC) Approval Authority

American Airlines requested that we revise paragraph (j) of the NPRM (79 FR 22908, April 25, 2014) to add information regarding Boeing’s authority to approve an AMOC. American Airlines stated that paragraph (j) of the NPRM does not provide operators information as to whether Boeing has the ability to grant AMOC approvals.

We do not agree with the commenter’s request. At this time, the FAA has delegated AMOC approvals to Boeing Authorized Representatives for structural modifications only. This AD requires an inspection or maintenance records check to determine the part numbers of the four PRSs, and replacement if necessary. This AD does not require, and Boeing Special Attention Service Bulletin 777–27– 0115, dated May 22, 2013, does not include, any structural modifications. We have not changed this AD in this regard. Conclusion

We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this AD as proposed except for minor editorial changes. We have determined that these minor changes:

• Are consistent with the intent that was proposed in the NPRM (79 FR 22908, April 25, 2014) for correcting the unsafe condition; and

• Do not add any additional burden upon the public than was already proposed in the NPRM (79 FR 22908, April 25, 2014). Costs of Compliance

We estimate that this AD affects 47 airplanes of U.S. registry.

We estimate the following costs to comply with this AD:



### E STIMATED 

### COSTS

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

Inspection ........................................................ 2 work-hours × $85 per hour = $170 ............. $0 $170 $7,990

We estimate the following costs to do any necessary replacements that would be required based on the results of the inspection. We have received no definitive data that would enable us to provide the cost of parts specified in this AD. We have no way of determining the number of airplanes that might need these replacements:



### O N 

### -CONDITION 

### C OSTS

Action Labor cost Parts cost Cost per product

Replacement (Up to 4 PRSs per airplane) .................... Up to 4 work-hours × $85 per hour = $340 .................. $0 Up to $340.

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 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment

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

**PART 39—AIRWORTHINESS DIRECTIVES** 

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

Authority: 49 U.S.C. 106(g), 40113, 44701.

**§ 39.13 [Amended]**

■ 2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD):
2014–23–04 The Boeing Company: Amendment 39–18020; Docket No.

For airplanes in group 1, as identified in Boeing Special Attention Service Bulletin 777–27–0115, dated May 22, 2013: A review of airplane maintenance records is acceptable in lieu of this inspection if the part number of the PRS can be conclusively determined from that review.
(h) Replacement

If any PRS having P/N 402875–05–01 is found during the inspection required by paragraph (g) of this AD: Before further flight, replace with a PRS having P/N 402875–03– 01, in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 777–27–0115, dated May 22,
2013.

**Airworthiness Directives; Bombardier, Inc. Airplanes** 

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

**ACTION :**  Final rule.

**SUMMARY :**  We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL–600–2B19 (Regional Jet Series 100 & 440) airplanes. This AD was prompted by a report indicating that inboard and outboard hydraulic lines of the brakes were found connected to the incorrect ports on the swivel assembly of the main landing gear (MLG). This AD requires modifying the MLG by installing a new bracket on the left and right lower aft-wing planks. We are issuing this AD to prevent incorrect installation of the brake hydraulic lines, which could cause the brakes and the anti-skid system to operate incorrectly, and consequent catastrophic failure of the airplane during a high-speed rejected takeoff.

**DATES :**  This AD becomes effective December 26, 2014.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of December 26, 2014.
