AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede 

Airworthiness Directive (AD) 2007–13– 

05, which applies to all The Boeing 

Company Model 777 airplanes. AD 

2007–13–05 currently requires 

repetitive measurements of the freeplay 

of the right and left elevators, rudder, 

and rudder tab, and related investigative 

and corrective actions if necessary. 

Since we issued AD 2007–13–05, the 

manufacturer determined that the 

procedure for the rudder freeplay 

inspection does not properly detect 

excessive freeplay in the rudder control 

load loop. This proposed AD would 

require repetitive freeplay inspections 

and lubrication of the right and left 

elevators, rudder, and rudder tab; and 

related investigative and corrective 

actions if necessary. We are proposing 

this AD to detect and correct flutter, 

which can cause damage to the control 

surface structure and consequent loss of 

control of the airplane. 

DATES: We must receive comments on 

this proposed AD by September 12, 

2014. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:

Discussion 

On April 11, 2007, we issued AD 

2007–13–05, Amendment 39–15109 (72 

FR 33856, June 20, 2007), for all The 

Boeing Company Model 777 airplanes. 

AD 2007–13–05 requires repetitive 

measurement of the freeplay of the right 

and left elevators, rudder, and rudder 

tab; and related investigative and 

corrective actions if necessary. AD 

2007–13–05 also requires repetitive 

lubrication of the elevator, rudder, and 

rudder tab components. AD 2007–13–05 

resulted from reports of freeplayinduced vibration of unbalanced control 

surfaces. We issued AD 2007–13–05 to 

detect and correct flutter, which can 

cause damage to the control surface 

structure and consequent loss of control 

of the airplane. 

Actions Since AD 2007–13–05, 

Amendment 39–15109 (72 FR 33856, 

June 20, 2007) Was Issued 

Since we issued AD 2007–13–05, 

Amendment 39–15109 (72 FR 33856, 

June 20, 2007), the manufacturer 

determined that the procedure for the 

rudder freeplay inspection does not 

properly detect excessive freeplay in the 

rudder control load loop. 

Relevant Service Information 

We reviewed Boeing Special 

Attention Service Bulletin 777–27– 

0062, Revision 2, dated January 27, 

2014. For information on the procedures 

and compliance times, see this service 

information at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2014– 

0485. 

FAA’s Determination 

We are proposing this AD because we 

evaluated all the relevant information 

and determined the unsafe condition 

described previously is likely to exist or 

develop in other products of the same 

type design. 

Proposed AD Requirements 

Although this proposed AD does not 

explicitly restate the requirements of AD 

2007–13–05, Amendment 39–15109 (72 

FR 33856, June 20, 2007), this proposed 

AD would retain all requirements of AD 

2007–13–05. Those requirements are 

referenced in the service information 

identified previously, which, in turn, is 

referenced in paragraphs (g) and (h) of 

this proposed AD. 

This proposed AD would require 

repetitive inspections (measurements) of 

the freeplay of the right and left 

elevators, rudder, and rudder tab; and 

related investigative and corrective 

actions if necessary. This proposed AD 

would also require repetitive lubrication 

of the elevator, rudder, and rudder tab 

components. 

The phrase ‘‘corrective actions’’ is 

used in this proposed AD. ‘‘Corrective 

actions’’ are actions that correct or 

address any condition found. Corrective 

actions in an AD could include, for 

example, repairs.

Costs of Compliance 

We estimate that this proposed AD 

affects 142 airplanes of U.S. registry. 

The new actions of this proposed AD 

would add no additional economic 

burden to that imposed by AD 2007–13– 

05, Amendment 39–15109 (72 FR 

33856, June 20, 2007). The current costs 

for this AD are repeated for the 

convenience of affected operators, as 

follows: 

ESTIMATED COSTS

0 $425 per lubrication cycle ......... $60,350 per lubrication cycle. 

We have received no definitive data 

that would enable us to provide cost 

estimates for the on-condition corrective 

actions specified in this proposed AD. 

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 

proposed AD would not have federalism 

implications under Executive Order 

13132. This proposed AD would 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 the proposed regulation: 

(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. 

List of Subjects in 14 CFR Part 39

Airworthiness Directives; The Boeing

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede 

Airworthiness Directive (AD) 2012–19– 

11, which applies to certain The Boeing 

Company Model 737 airplanes. AD 

2012–19–11 currently requires 

incorporating design changes to 

improve the reliability of the cabin 

altitude warning system by installing a 

redundant cabin altitude pressure 

switch, replacing the aural warning 

module (AWM) with a new or reworked 

AWM, and changing certain wire 

bundles or connecting certain 

previously capped and stowed wires as 

necessary. For certain airplanes, AD 

2012–19–11 also requires prior or 

concurrent incorporation of related 

design changes by modifying the 

instrument panels, installing light 

assemblies, modifying the wire bundles, 

and installing a new circuit breaker, as 

necessary. Since we issued AD 2012– 

19–11, we have determined that certain 

airplanes were not included in the 

requirement to incorporate related 

design changes. This proposed AD 

would add, for certain airplanes, a 

requirement to incorporate related 

design changes. This proposed AD also, 

for certain airplanes, no longer gives 

credit for accomplishing certain 

previous actions. We are proposing this 

AD to prevent the loss of cabin altitude 

warning, which could delay flightcrew 

recognition of a lack of cabin 

pressurization, and could result in 

incapacitation of the flightcrew due to 

hypoxia (a lack of oxygen in the body), 

and consequent loss of control of the 

airplane. 

DATES: We must receive comments on 

this proposed AD by September 12, 

2014. 

ADDRESSES: You may send comments,
