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 all The 

Boeing Company Model 727 airplanes. 

This AD was prompted by a report of 

cracking in the left-side chord of the fin 

closure rib on the vertical stabilizer. 

This AD requires repetitive inspections 

of the left and right side chords of the 

fin closure rib for cracking and 

corrosion, and related investigative and 

corrective actions if necessary. We are 

issuing this AD to detect and correct 

cracking and corrosion in the left- and 

right-side chords of the fin closure rib, 

which could lead to widespread 

cracking in the chords that might 

weaken the fin closure rib structure and 

result in loss of airplane control due to 

lack of horizontal stabilizer support. 

DATES: This AD is effective September 

20, 2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of September 20, 2013.

SUPPLEMENTARY INFORMATION: 

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. The 

NPRM published in the Federal 


tkelley on DSK3SPTVN1PROD with RULES
Federal Register / Vol. 78, No. 159 / Friday, August 16, 2013 / Rules and Regulations 49907 

Register on May 2, 2013 (78 FR 25662). 

The NPRM proposed to require 

repetitive inspections of the left- and 

right-side chords of the fin closure rib 

for cracking and corrosion, and related 

investigative and corrective actions if 

necessary. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

have considered the comments received. 

Boeing stated that it supports the NPRM 

(78 FR 25662, May 2, 2013). 

FedEx Express commented that it has 

four airplanes that will be affected by 

the NPRM (78 FR 25662, May 2, 2013). 

This commenter also noted that the 

proposed inspection threshold and 

intervals can be accomplished within its 

planned scheduled maintenance checks, 

that the work-hours and elapsed time to 

accomplish the proposed inspections 

will not impact the overall span-time of 

the planned scheduled maintenance 

check, and that the proposed 

inspections do not require any special 

inspection techniques, training, or 

tooling. 

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 (78 FR 

25662, May 2, 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 25662, 

May 2, 2013). 

Costs of Compliance 

We estimate that this AD affects 98 

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 

Inspections ....... 17 work-hours × $85 per hour = 

$1,445 per inspection cycle.

$0 $1,445 per inspection cycle ............. $141,610 per inspection cycle. 

We have received no definitive data 

that would enable us to provide cost 

estimates for the on-condition actions 

specified in this 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 

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.

SUPPLEMENTARY INFORMATION: 

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. The 

NPRM published in the Federal 

Register on May 22, 2013 (78 FR 30243). 

The NPRM proposed to require either 

incorporating updates to the aircraft 

computer system or incorporating a 

temporary revision to the aircraft flight 

manual. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (78 

FR 30243, May 22, 2013) or on the 

determination of the cost to the public. 

However, we have received a revision to 

one of the service bulletins referenced 

in the NPRM. The revision does not add 

any additional burden to the owners/ 

operators of the airplanes affected by the 

NPRM; therefore, we are including the 

revised service information into this AD 

as an additional method of compliance. 

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

unsafe condition; and 

• Do not add any additional burden
