Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are superseding an 

existing airworthiness directive (AD) for 

certain The Boeing Company Model 

747–100, 747–100B, 747–100B SUD, 

747–200B, 747–200C, 747–200F, 747– 

300, 747–400, 747–400D, 747–400F, 

747SR, and 747SP series airplanes; and 

certain Model 757–200, –200PF, and 

–300 series airplanes. That AD currently 

requires replacing the control switches 

of the forward, aft, and nose cargo doors 

of Model 747 airplanes; and requires 

replacing the control switches of cargo 

doors 1 and 2 of Model 757 series 

airplanes. This new AD adds airplanes 

to the applicability and revises the 

initial compliance times for those 

airplanes. This AD was prompted by 

reports of problems associated with the 

uncommanded operation of cargo doors. 

We are issuing this AD to prevent 

injuries to persons and damage to the 

airplane and equipment. 

DATES: This AD is effective February 22, 

2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of February 22, 2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain other publications listed in 

this AD as of December 3, 2009 (74 FR 

55763, October 29, 2009).

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2009–22–08, 

Amendment 39–16059 (74 FR 55763, 

October 29, 2009). That AD applies to 

the specified products. The NPRM 

published in the Federal Register on 

August 3, 2012 (77 FR 46343). That 

NPRM proposed to continue to require 

replacing the control switches of the 

forward, aft, and nose cargo doors of 

Model 747 airplanes; and the control 

switches of cargo doors 1 and 2 of 

Model 757 airplanes. That NPRM also 

proposed to add airplanes to the 

applicability and to revise the initial 

compliance times for those airplanes. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the proposal (77 FR 46343, 

August 3, 2012) and the FAA’s response 

to each comment. 

Support for the NPRM (77 FR 46343, 

August 3, 2012) 

Boeing supported the NPRM (77 FR 

46343, August 3, 2012). 

American Airlines found that the 

NPRM (77 FR 46343, August 3, 2012) 

would not require additional actions for 

its Model 757 fleet; therefore, American 

Airlines had no comments concerning 

the NPRM. 

Request for Clarification of Proposed 

Compliance Times 

Asiana Airlines requested that we 

clarify the compliance times specified 

in paragraph (g) of the NPRM (77 FR 

46343, August 3, 2012). Specifically, 

Asiana Airlines requested clarification 

of the compliance times for Model 747 

Groups 1 and 2 airplanes on which the 

door switches had been replaced before 

the effective date of AD 2009–22–08, 

Amendment 39–16059 (74 FR 55763, 

October 29, 2009), per Boeing Special 

Attention Service Bulletin 747–52– 

2286, dated September 28, 2007; and on 

which the certificate of airworthiness 

had been issued long before 72 months 

after the effective date of AD 2009–22– 

08. 

We agree to provide clarification. 

Paragraph (g)(1) of this AD restates the 

compliance time from AD 2009–22–08, 

Amendment 39–16059 (74 FR 55763, 

October 29, 2009) for Groups 1 and 2 

Model 747 airplanes identified in 

Boeing Special Attention Service 

Bulletin 747–52–2286, Revision 1, dated 

October 28, 2010. If an operator has 

already replaced the switches before the 

effective date of this AD in accordance 

with either Boeing Special Attention 

Service Bulletin 747–52–2286, dated 

September 28, 2007; or Boeing Special 

Attention Service Bulletin 747–52– 

2286, Revision 1, dated October 28, 

2010; then no further action is necessary 

for compliance with paragraph (g) of 

this AD. No change to this AD is 

necessary. 

Explanation of Change Made to This 

AD 

We have added new paragraph (i)(3) 

to this final rule to allow delegation of 

repairs to the Boeing Commercial 

Airplanes Organization Designation 

Authorization (ODA). We have reidentified subsequent paragraphs 

accordingly. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting the AD 

with the change described previously— 

and minor editorial changes. We have 

determined that these minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (77 FR 

46343, August 3, 2012) for correcting 

the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (77 FR 46343, 

August 3, 2012).

Costs of Compliance 

We estimate that this AD affects 225 

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 Number of 

airplanes 

Cost on U.S. 

operators 

Replacement [retained from existing AD 2009–22–08, Amendment 39–16059 (74 FR 55763, 

October 29, 2009)].

Up to 5 work-hours × $85 per 

hour = $425.

$195 Up to $620 ........ 221 Up to $137,020. 

Replacement [new action for 

added airplanes].

5 work-hours × $85 per hour = 

$425.

195 $620 .................. 4 $2,480. 

According to the manufacturer, some 

of the costs of this AD may be covered 

under warranty, thereby reducing the 

cost impact on affected individuals. We 

do not control warranty coverage for 

affected individuals. As a result, we 

have included all costs in our cost 

estimate. 

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 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.

stress corrosion. We are issuing this AD 

to require actions to address the unsafe 

condition on these products. 

DATES: This AD is effective February 7, 

2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD
