Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 767–200, 

–300, –300F, and –400ER airplanes. 

This proposed AD was prompted by 

reports indicating that a standard access 

door was located where an impactresistant access door was required, and 

stencils were missing from some 

impact-resistant access doors. This 

proposed AD would require an 

inspection of the left- and right-hand 

wing fuel tank access doors to 

determine that impact-resistant access 

doors are installed in the correct 

locations, and to replace any door with 

an impact-resistant access door if 

necessary. This proposed AD also 

would require an inspection for stencils 

and index markers on impact-resistant 

access doors, and application of new 

stencils or index markers if necessary. 

This proposed AD would also require 

revising the maintenance program to 

incorporate changes to the airworthiness 

limitations section. We are proposing 

this AD to prevent foreign object 

penetration of the fuel tank, which 

could cause a fuel leak near an ignition 

source (e.g., hot brakes or engine 

exhaust nozzle), consequently leading to 

a fuel-fed fire. 

DATES: We must receive comments on 

this proposed AD by September 26, 

2013. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this proposed AD. 

Discussion 

We received reports of a standard 

access door located where an impactresistant access door is required, and 

stencils were missing from some spare 

impact-resistant access doors. This 

condition, if not corrected, could result 

in foreign object penetration of the fuel 

tank, which could cause a fuel leak near 

an ignition source (e.g., hot brakes or 

engine nozzle), consequently leading to 

a fuel-fed fire. 

Relevant Service Information 

We reviewed Boeing Service Bulletin 

767–28–0105, dated January 12, 2012; 

and critical design configuration control 

limitation (CDCCL) Task 57–AWL–01, 

‘‘Impact-Resistant Fuel Tank Access 

Door,’’ of Section 9, Airworthiness 

Limitations (AWLs) and Certification 

Maintenance Requirements (CMRs) of 

Boeing 767 Maintenance Planning Data 

Document D622T001–9, Revision 

October 2012. For information on the 

procedures and compliance times, see 

this service information at http:// 

www.regulations.gov by searching for 

Docket No. FAA–2013–0672. 

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 

The FAA issued section 121.316 of 

the Federal Aviation Regulations (14 

CFR 121.316) requiring that each 

turbine powered transport category 

airplane meet the requirements of 

section 25.963(e) of the Federal Aviation 

Regulations (14 CFR 25.963(e)). Section 

25.963(e) outlines the certification 

requirements for fuel tank access covers 

on turbine powered transport category 

airplanes. 

This proposed AD would require 

inspecting fuel tank access doors to 

determine that impact-resistant access 

doors are installed in the correct 

locations and replacing any door with 

an impact-resistant access door if 

necessary; inspecting application of 

stencils and index markers of impactresistant access doors and application of 

new stencils or index markers if 

necessary; and revising the maintenance 

program. 

This proposed AD requires revisions 

to certain operator maintenance 

documents to include a new CDCCL. 

Compliance with CDCCLs is required by 

section 91.403(c) of the Federal Aviation 

Regulations (14 CFR 91.403(c)). For 

airplanes that have been previously 

modified, altered, or repaired in the 

areas addressed by this proposed AD, 

the operator might not be able to 

accomplish the actions described in the 

revisions. In this situation, to comply 

with 14 CFR 91.403(c), the operator 

must request approval for an alternative 

method of compliance according to the 

procedures specified in paragraph (j) of 

this proposed AD. The request should 

include a description of changes to the 

required actions that will ensure the 

continued damage tolerance of the 

affected structure. 

After accomplishing the revision 

required by paragraph (h) of this AD, no 

alternative actions (e.g., inspections), 

intervals, and/or CDCCLs may be used 

unless the actions, intervals, and/or 

CDCCLs are approved as an alternative 

method of compliance (AMOC) in 

accordance with the procedures 

specified in paragraph (j) of this AD. 

Costs of Compliance 

We estimate that this proposed AD 

affects 425 airplanes of U.S. registry. We 

estimate the following costs to comply 

with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

roduct 

Cost on U.S. 

perators 

Inspection ........................................................ Up to 7 work-hours × $85 per hour = $595 ... $0 $595 $252,875 

Maintenance program revision ....................... 1 work-hour × $85 per hour = $85 ................. 0 85 36,125 

We estimate the following costs to do 

any necessary replacements that would 

be required based on the results of the 

proposed inspection. We have no way of 

determining the number of aircraft that 

might need these replacements: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per product 

Replacement per door .............................................. 3 work-hours × $85 per hour = $255 ....................... $8,000 $8,255 

Stencil and index marker .......................................... 9 work-hours × $85 per hour = $765 ....................... 0 765 

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 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 proposed 

regulation is within the scope of that 


ehiers on DSK2VPTVN1PROD with PROPOSALS-1
48828 Federal Register / Vol. 78, No. 155 / Monday, August 12, 2013 / Proposed Rules 

authority because it addresses an unsafe 

condition that is likely to exist or 

develop on products identified in this 

rulemaking action. 

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, Incorporation by reference, 

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:

indicating that a standard access door was 

located where an impact-resistant access 

door was required, and stencils were missing 

from some impact-resistant access doors. We 

are issuing this AD to prevent foreign object 

penetration of the fuel tank, which could 

cause a fuel leak near an ignition source (e.g., 

hot brakes or engine nozzle), consequently 

leading to a fuel-fed fire.

Within 72 months after the effective date 

of this AD, do the actions specified in 

paragraphs (g)(1) and (g)(2) of this AD, in 

accordance with the Accomplishment 

Instructions of Boeing Service Bulletin 767– 

28–0105, dated January 12, 2012. 

(1) Do either a general visual inspection or 

ultrasonic non-destructive test of the left- and 

right-hand wing fuel tank access doors to 

determine whether impact-resistant access 

doors are installed in the correct locations. If 

any standard access door is found, before 

further flight, replace with an impactresistant access door, in accordance with the 

Accomplishment Instructions of Boeing 

Service Bulletin 767–28–0105, dated January 

12, 2012. 

(2) Do a general visual inspection of the 

left- and right-hand wing fuel tank impactresistant access doors to verify stencils and 

index markers are applied. If a stencil or 

index marker is missing, before further flight, 

apply stencil or index marker, as applicable, 

in accordance with the Accomplishment 

Instructions of Boeing Service Bulletin 767– 

28–0105, dated January 12, 2012. 

(h) Maintenance Program Revision 

Within 60 days after the effective date of 

this AD, revise the maintenance program to 

incorporate critical design configuration 

control limitation (CDCCL) Task 57–AWL– 

01, ‘‘Impact-Resistant Fuel Tank Access 

Door,’’ of Section 9, Airworthiness 

Limitations (AWLs) and Certification 

Maintenance Requirements (CMRs) of Boeing
