AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all 

Airbus Model A318 series airplanes, 

Model A319 series airplanes, Model 

A320–211, –212, –214, –231, –232, and 

–233 airplanes, and Model A321 series 

airplanes. This AD was prompted by a 

report of a circumferential crack at the 

gland retaining-ring groove of certain 

retraction actuators on the main landing 

gear (MLG). This AD requires an 

inspection to identify the part numbers 

of MLG retraction actuators and 

replacement of certain MLG retraction 

actuators. We are issuing this AD to 

prevent MLG retraction actuator failure 

that could prevent the full extension 

and/or down-locking of the MLG, 

possibly resulting in MLG collapse 

during landing or rollout, and 

consequent damage to the airplane and 

injury to the occupants. 

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.

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 all Airbus Model A318 series 

airplanes, Model A319 series airplanes, 

Model A320–211, –212, –214, –231, 

–232, and –233 airplanes, and Model 

A321 series airplanes. The NPRM 

published in the Federal Register on 

July 17, 2014 (79 FR 41658). 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2013–0283R1, 

dated December 9, 2013 [Corrected 

December 11, 2013] (referred to after 

this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for the specified products. The MCAI 

states: 

During routine pre-flight inspection of an 

Airbus A319, a hydraulic fluid leak was 

detected, coming from the retraction actuator 

of the main landing gear (MLG). The results 

of subsequent investigations revealed that a 

galvanic difference between materials 

induced an internal corrosion which was the 

crack initiator of the component. Actuators 

from 201590 series were identified as 

potentially affected, unless inspected and 

corrected during MLG overhaul. 

This condition, if not detected and 

corrected, could lead to retraction actuator 

failure, preventing the full extension and/or 

down-locking of the MLG, possibly resulting 

in MLG collapse during landing or rollout 

and consequent damage to the aeroplane and 

injury to occupants. 

To address this potential unsafe condition, 

Airbus published Service Bulletin (SB) 

A320–32–1408, providing instructions to 

identify and replace the affected actuators 

that have already exceeded 20,000 flight 

cycles (FC) or 10 years of operation since 

new, or since last overhaul. 

For the reason described above, EASA AD 

2013–0283 was issued to require a one-time 

identification and replacement of each 

affected MLG retraction actuator.

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (79 

FR 41658, July 17, 2014) or on the 

determination of the cost to the public. 

Clarification of Costs of Compliance 

We have revised the Costs of 

Compliance section of this AD to clarify 

the costs of the follow-on actions. 

Conclusion 

We reviewed the relevant data 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 

41658, July 17, 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 41658, 

July 17, 2014). 

Costs of Compliance 

We estimate that this AD affects 851 

airplanes of U.S. registry. 

We also estimate that it will take 

about 3 work-hours per product to 

comply with the basic requirements of 

this AD. The average labor rate is $85 

per work-hour. Based on these figures, 

we estimate the cost of this AD on U.S. 

operators to be $217,005, or $255 per 

product. 


rmajette on DSK2VPTVN1PROD with RULES
69034 Federal Register / Vol. 79, No. 224 / Thursday, November 20, 2014 / Rules and Regulations 

In addition, we estimate that any 

necessary follow-on actions will take 

about 8 work-hours and require parts 

costing $36,135 per MLG actuator, for a 

cost of $36,845 per MLG actuator. We 

have no way of determining the number 

of aircraft that might need these actions. 

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 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 the 

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.

ACTION: Final rule. 

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 to 

safely assume control and execute a goaround or manual landing. 

DATES: This AD is effective December 

26, 2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD
