SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this proposal. Send your comments to 

an address listed under the ADDRESSES

section. Include ‘‘Docket No. FAA– 

2012–0938; Directorate Identifier 2011– 

NM–271–AD’’ at the beginning of your 

comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this proposed AD. We will 

consider all comments received by the 

closing date and may amend this 

proposed AD because of those 

comments. 

We will post all comments we 

receive, without change, to http:// 

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 early fatigue 

cracks near chem-mill areas on the 

crown skin panels of Model 737–300, 

–400, and –500 series airplanes. The 

cracks resulted from high stresses in the 

areas where chem-mill pockets are 

adjacent to non-chem-mill areas. 

Although we have not received any 

reports of this type of fuselage fatigue 

cracks on Model 737–600, –700, –700C, 

–800, –900, or –900ER series airplanes, 

a full-scale fatigue test article was 

inspected for skin cracks at similar 

structural details and two chem-mill 

cracks were found that occurred late in 

the testing program. This condition, if 

not detected and corrected, could result 

in rapid decompression of the airplane. 

Relevant Service Information 

We reviewed Boeing Service Bulletin 

737–53–1309, dated October 20, 2011, 

for Model 737–600 series airplanes. 

That service bulletin describes, among 

other things, procedures for doing 

repetitive external detailed inspections 

and external non-destructive 

inspections (medium frequency eddy 

current (MFEC), magneto optic imager 

(MOI), C-scan, or ultrasonic phased 

array (UTPA) inspections) of the 

fuselage skin at specified locations 

where chem-mill areas are adjacent to 

non-chem-mill areas at antenna and 

door bearstrap installations, and repairs 

if necessary. 

Boeing Service Bulletin 737–53–1309, 

dated October 20, 2011, also describes 

procedures for installing modification 

doublers, which involves an external 

detailed inspection and an external nondestructive (MFEC, MOI, C-scan, or 

UTPA) inspection for any cracking of 

the area to be modified prior to the 

doubler being placed on that area, a 

high frequency eddy current inspection 

of all existing holes for cracking, and 

contacting Boeing if necessary. The 

service bulletin also specifies that when 

a certain modification is accomplished, 

the repetitive inspection for the area 

under the modification is no longer 

necessary. 

Boeing Service Bulletin 737–53–1309, 

dated October 20, 2011, specifies an 

initial compliance time of 43,000 total 

flight cycles, or 1,500 flight cycles after 

the original issue date of that service 

bulletin, whichever occurs later. That 

service bulletin specifies a repetitive 

interval not to exceed 1,500 flight cycles 

or 2,100 flight cycles, depending on 

inspection method. 

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 the same 

type design. 

Proposed AD Requirements 

This proposed AD would require 

accomplishing the actions specified in 

the service information described 

previously, except as discussed under 

‘‘Differences Between the Proposed AD 

and the Service Information.’’ 

Similar Rulemaking 

The crown skin panels on Model 737– 

600 series airplanes are of a similar 

design to those on Model 737–300, 

–400, –500, –700, –700C, –800, –900, 

and –900ER series airplanes. Therefore, 

all these models may be subject to the 

identified unsafe condition. We are 

considering similar rulemaking for these 

additional models. 

Differences Between the Proposed AD 

and the Service Information 

Boeing Service Bulletin 737–53–1309, 

dated October 20, 2011, specifies to 

contact the manufacturer for disposition 

of certain repair conditions, but this 

proposed AD would require repairing 

those conditions in one of the following 

ways: 

• In accordance with a method that 

we approve; or 

• Using data that meet the 

certification basis of the airplane, and 

that have been approved by the Boeing 

Commercial Airplanes Organization 

Designation Authorization (ODA) whom 

we have authorized to make those 

findings. 

Tables 2 and 3 in paragraph 1.E., 

‘‘Compliance,’’ of Boeing Service 

Bulletin 737–53–1309, dated October 

20, 2011, specify post-modification 

inspections at certain chem-mill step 

locations, which may be used in support 

of compliance with section 

121.1109(c)(2) or 129.109(c)(2) of the 

Federal Aviation Regulations (14 CFR 

121.1109(c)(2) or 129.109(c)(2)). 

However, this NPRM does not propose 

mstockstill on DSK4VPTVN1PROD with PROPOSALS

Federal Register / Vol. 77, No. 181 / Tuesday, September 18, 2012 / Proposed Rules 57543 

to require those post-modification 

inspections. This difference has been 

coordinated with Boeing. 

Costs of Compliance 

We estimate that this proposed AD 

affects 6 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 product Cost on U.S. operators 

Inspection of chem-mill 

step locations.

37 work-hours × $85 per hour = $3,145 per inspection cycle.None ............ $3,145 per inspection 

cycle.

$18,870 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 proposed 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 

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

SUPPLEMENTARY INFORMATION: 

I. Background 

The Native American Housing 

Assistance and Self-Determination Act 

of 1996 (25 U.S.C. 4101 et seq.) 

(NAHASDA) changed the way that 

housing assistance is provided to Native 

Americans. NAHASDA eliminated 

several separate assistance programs 

and replaced them with a single block 

grant program, known as the Indian 

Housing Block Grant (IHBG) program. 

The regulations governing the IHBG 

formula allocation are codified in 

subpart D of part 1000 of HUD’s 

regulations in title 24 of the Code of 

Federal Regulations. In accordance with 

section 106 of NAHASDA, HUD 

developed the regulations with active 

tribal participation using the procedures 

of the Negotiated Rulemaking Act of 

1990 (5 U.S.C. 561–570). 

Under the IHBG program, HUD makes 

assistance available to eligible Indian 

tribes for affordable housing activities. 

The amount of assistance made 

available to each Indian tribe is 

determined using a formula that was 

developed as part of the NAHASDA
