Identifier 2017–NM–090–AD] 

RIN 2120–AA64 

Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede 

Airworthiness Directive (AD) 2013–01– 

02, which applies to 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 Model 757–200, 

–200PF, and –300 series airplanes. AD 

2013–01–02 requires replacing the 

control switches of certain cargo doors. 

Since we issued AD 2013–01–02, 

additional un-commanded cargo door 

operation has been reported. This 

proposed AD would require 

replacement of certain cargo door 

control switches with a new improved 

switch; installation of an arm switch in 

certain cargo doors; operational and 

functional tests; and applicable oncondition actions. This proposed AD 

would also add airplanes to the 

applicability. We are proposing this AD 

to address the unsafe condition on these 

products. 

DATES: We must receive comments on 

this proposed AD by November 20, 

2017.

Discussion 

On January 4, 2013, we issued AD 

2013–01–02, Amendment 39–17316 (78 

FR 4051, January 18, 2013) (‘‘AD 2013– 

01–02’’), 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 Model 757–200, 

–200PF, and –300 series airplanes. AD 

2013–01–02 requires replacing the 

control switches of the forward, aft, and 

nose cargo doors of Model 747 

airplanes; and replacing the control 

switches of cargo doors 1 and 2 of 

Model 757 series airplanes. AD 2013– 

01–02 resulted from reports of problems 

associated with the uncommanded 

operation of cargo doors. We issued AD 

2013–01–02 to prevent injuries to 

persons and damage to the airplane. 

Actions Since AD 2013–01–02 Was 

Issued 

Since we issued AD 2013–01–02, 

additional un-commanded cargo door 

operation has been reported. In the most 

recent report the switch had only been 

installed for 44 months. Testing of failed 

switches found that the cargo door 

control switch can remain actuated after 

released to the OFF position. We have 

determined that the replacements 

required by AD 2013–01–02 do not 

adequately address the identified unsafe 

condition and that new improved 

switches must be installed. With a new 

cargo door control and arm switch 

configuration installed, the operator 

must manually move both switches to 

operate the cargo door. Both switches 

are spring loaded to the off position and 

releasing either switch will stop the 

door operation. 

We have also determined that certain 

Model 757–200CB series airplanes and 

Model 747–8F and 747–8 series 

airplanes are affected by the identified 

unsafe condition and must be included 

in this proposed AD. 

Related Service Information Under 1 

CFR Part 51 

We reviewed the following Boeing 

service information. 

• Boeing Service Bulletin 747–52– 

2307, dated May 23, 2017, and Boeing 

Service Bulletin 747–52–2308, dated 

June 5, 2017. This service information 

describes procedures for replacement of 

the nose, forward, and aft cargo door 

control switches with new improved 

switches, installation of an arm switch 

in the forward and aft cargo doors, a 

nose cargo door normal operational test, 

forward and aft cargo door open and 

close functional tests, and applicable 

on-condition actions. These documents 

are distinct since they apply to different 

airplane models in different 

configurations. 

• Boeing Service Bulletin 757–52– 

0093, Revision 1, dated April 21, 2017. 

This service information describes 

procedures for replacement of the 

forward and aft cargo door control 


asabaliauskas on DSKBBXCHB2PROD with PROPOSALS
Federal Register / Vol. 82, No. 193 / Friday, October 6, 2017 / Proposed Rules 46723 

switches with new improved switches, 

installation of an arm switch in the 

forward and aft cargo doors, an 

operational test of the No. 1 and No. 2 

cargo doors, repetitive functional tests 

of the No. 1 and No. 2 cargo doors, and 

applicable on-condition actions. 

This service information is reasonably 

available because the interested parties 

have access to it through their normal 

course of business or by the means 

identified in the ADDRESSES section. 

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 these same 

type designs. 

Proposed AD Requirements 

This proposed AD would retain none 

of the requirements of AD 2013–01–02. 

This proposed AD would require 

accomplishing the actions identified as 

‘‘RC’’ (required for compliance) in the 

Accomplishment Instructions of Boeing 

Service Bulletin 747–52–2307, dated 

May 23, 2017; Boeing Service Bulletin 

747–52–2308, dated June 5, 2017; and 

Boeing Service Bulletin 757–52–0093, 

Revision 1, dated April 21, 2017; as 

applicable; except for any differences 

identified as exceptions in the 

regulatory text of this proposed AD. 

This proposed AD also would add 

airplanes to the applicability. 

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–2017– 

0905. 

Differences Between This Proposed AD 

and the Service Information 

The effectivity of Boeing Service 

Bulletin 757–52–0093, Revision 1, dated 

April 21, 2017, is limited to Model 757– 

200, –200CB, –200PF, and –300 series 

airplanes, line numbers 1 through 1050. 

However, the applicability of this 

proposed AD includes four additional 

Model 757 airplanes, variable numbers 

NP901 through NP904 inclusive. We 

have included this difference because of 

new findings related to these additional 

airplanes indicating they are subject to 

the identified unsafe condition. This 

difference has been coordinated with 

Boeing. Additionally, Boeing has 

indicated that Boeing Service Bulletin 

757–52–0093, Revision 1, dated April 

21, 2017, will be revised to include the 

additional airplanes. We will consider 

including the revised service 

information, if available, in the final 

rule. 

Costs of Compliance 

We estimate that this proposed AD 

affects 584 airplanes of U.S. registry. We 

estimate the following costs to comply 

with this proposed AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Replacement (Boeing Service Bulletin 

747-52-2307) (14 airplanes).

78 work-hours × $85 per hour = $6,630 $12,874 $19,504 ................ $273,056. 

Replacement (Boeing Service Bulletin 

747-52-2308) (94 airplanes).

24 work-hours × $85 per hour = $2,040 980 3,020 .................... 283,880. 

Replacement (Boeing Service Bulletin 

757-52-0093) (476 airplanes).

51 work-hours × $85 per hour = $4,335 10,626 14,961 .................. 7,121,436. 

Repetitive Test (Boeing Service Bulletin 

757-52-0093) (476 airplanes).

3 work-hours × $85 per hour = $255 per 

test cycle.

0 255 per test cycle 121,380 per test 

cycle. 

According to the manufacturer, some 

of the costs of this proposed 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 available 

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. 

This proposed AD is issued in 

accordance with authority delegated by 

the Executive Director, Aircraft 

Certification Service, as authorized by 

FAA Order 8000.51C. In accordance 

with that order, issuance of ADs is 

normally a function of the Compliance 

and Airworthiness Division, but during 

this transition period, the Executive 

Director has delegated the authority to 

issue ADs applicable to transport 

category airplanes to the Director of the 

System Oversight Division. 

Regulatory Findings 

We 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 this 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 

Air transportation, Aircraft, Aviation

Safety. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows:

(j) Alternative Methods of Compliance 

(AMOCs) 

(1) The Manager, Seattle ACO Branch, 

FAA, has the authority to approve AMOCs 

for this AD, if requested using the procedures 

found in 14 CFR 39.19. In accordance with 

14 CFR 39.19, send your request to your 

principal inspector or local Flight Standards 

District Office, as appropriate. If sending 

information directly to the manager of the 

certification office, send it to the attention of 

the person identified in paragraph (k)(1) of 

this AD. Information may be emailed to: 9- 

ANM-Seattle-ACO-AMOC-Requests@faa.gov.

identified in an RC step, must be done to 

comply with the AD. If a step or substep is 

labeled ‘‘RC Exempt,’’ then the RC 

requirement is removed from that step or 

substep. An AMOC is required for any 

deviations to RC steps, including substeps 

and identified figures. 

(ii) Steps not labeled as RC may be 

deviated from using accepted methods in 

accordance with the operator’s maintenance 

or inspection program without obtaining 

approval of an AMOC, provided the RC steps, 

including substeps and identified figures, can 

still be done as specified, and the airplane 

can be put back in an airworthy condition.
