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 M7 Aerospace LLC Models 

SA226–AT, SA226–T, SA226–T(B), 

SA226–TC, SA227–AC (C–26A), 

SA227–AT, SA227–BC (C–26A), 

SA227–CC, SA227–DC (C–26B), SA227– 

TT, SA26–AT, and SA26–T airplanes. 

The NPRM published in the Federal 

Register on December 24, 2013 (78 FR 

77618). The NPRM was prompted by 

reports of airplanes with multiple 

fatigue cracks in the FS 69.31 front 

pressure bulkhead. The NPRM proposed 

to require repetitively inspecting 

(visually) the FS 51.31 front pressure 

bulkhead on SA26 series airplanes and 

FS 69.31 front pressure bulkhead on 

SA226 and SA227 series airplanes for 

cracks, and repairing any cracked 

bulkhead. This NPRM also proposed to 

require reporting certain inspection 

results to M7 Aerospace LLC. We are 

issuing this AD to correct the unsafe 

condition on these products. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (78 

FR 77618, December 24, 2013) or on the 

determination of the cost to the public. 

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 (78 FR 

77618, December 24, 2013) for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (78 FR 77618, 

December 24, 2013). 

Costs of Compliance 

We estimate that this AD affects 360 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product Cost on U.S. operators 

Inspect visually F.S. 69.31 or F.S. 51.31 bulkhead (as applicable), looking for cracking in 

the radius.

12 work-hours × $85 

per hour = $1,020 

per inspection.

Not Applicable .............. $1,020 $367,200 per inspection 

cycle. 

We estimate the following costs to do 

any necessary repairs that would be 

required based on the results of the 

inspection. We have no way of 

determining the number of airplanes 

that might need these repairs: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Repair damage ..................................................................... 400 work-hours × $85 per hour = $34,000 .......... $8,000 $42,000 

Paperwork Reduction Act 

A federal agency may not conduct or 

sponsor, and a person is not required to 

respond to, nor shall a person be subject 

to penalty for failure to comply with a 

collection of information subject to the 

requirements of the Paperwork 

Reduction Act unless that collection of 

information displays a current valid 

OMB control number. The control 

number for the collection of information 

required by this AD is 2120–0056. The 

paperwork cost associated with this AD 

has been detailed in the Costs of 

Compliance section of this document 

and includes time for reviewing 

instructions, as well as completing and 

reviewing the collection of information. 

Therefore, all reporting associated with 

this AD is mandatory. Comments 

concerning the accuracy of this burden 

and suggestions for reducing the burden 

should be directed to the FAA at 800

Collection Clearance Officer, AES–200. 

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.

RIN 2120–AA64 

Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 747–200B, 

747–300, 747–400, 747–400D, 747–400F 

series airplanes, and Model 767 series 

airplanes, powered by General Electric 

(GE) CF6–80C2 engines. This AD was 

prompted by reports of failure of the 

electro mechanical brake flexshaft (short 

flexshaft) of the thrust reverser actuation 

system (TRAS). This AD requires 

replacing the short flexshaft on each 

engine with a new short flexshaft, 

testing of the electro mechanical brake 

and center drive unit (CDU) cone brake 

to verify the holding torque, and 

performing related investigative and 

corrective actions if necessary. We are 

issuing this AD to prevent an 

uncommanded in-flight thrust reverser 

deployment and consequent loss of 

control of the airplane. 

DATES: This AD is effective April 25, 

2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of April 25, 2014.
