Airworthiness Directives; Boeing 

Model 737–600, –700, –700C, –800, and 

–900 Series Airplanes, Equipped with 

CFM56–7 Engines 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede an existing airworthiness 

directive (AD) that applies to certain 

Boeing Model 737–600, –700, and –800 

series airplanes. The existing AD 

currently requires repetitive inspections 

to detect damage of the aft strut 

insulation blanket, and eventual 

replacement of the insulation blankets 

with new, improved blankets. This 

proposed AD would add airplanes to the 

applicability and require installation of 

a new heat insulation blanket and new 

cover plate on the left and right side 

engine struts. This proposed AD would 

not retain the requirements of the 

existing AD and would terminate the 

requirements of the existing AD. This 

proposed AD results from reports of 

damaged heat insulation blankets on the 

engine struts. We are proposing this AD 

to prevent exposure of the lower surface 

of the strut to extreme high 

temperatures, consequent creation of a 

source of fuel ignition, and increased 

risk of an uncontrollable fire and 

possible fuel tank explosion. 

DATES: We must receive comments on 

this proposed AD by March 24, 2008.

SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this proposed AD. Send your comments 

to an address listed under the 

ADDRESSES section. Include ‘‘Docket No. 

FAA–2008–0147; Directorate Identifier 

2007–NM–294–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 

On February 4, 1999, we issued AD 

99–04–11, amendment 39–11035 (64 FR 

6791, February 11, 1999), for certain 

Boeing Model 737–600, –700, and –800 

series airplanes. That AD requires 

repetitive inspections to detect damage 

of the aft strut insulation blanket. That 

AD also requires eventual replacement 

of the insulation blankets with new, 

improved blankets, which constitutes 

terminating action for the requirements 

of that AD. That AD resulted from 

reports of damaged aft strut insulation 

blankets. We issued that AD to prevent 

such damage, which could result in 

exposure of the lower surface of the 

strut to extreme high temperatures, 

consequent creation of a source of fuel 

ignition, and increased risk of an 

uncontrollable fire and possible fuel 

tank explosion. 

Actions Since Existing AD Was Issued 

Since we issued AD 99–04–11, we 

have received reports of failures of the 

insulation blankets that were installed 

in accordance with the requirements of 

that AD. A failed heat insulation blanket 

might go undetected in that area. 

Relevant Service Information 

We have reviewed Boeing Special 

Attention Service Bulletin 737–54–

1045, dated July 25, 2007. The service 

bulletin describes procedures for 

installing a new heat insulation blanket, 

P/N S315A213–57, and a new cover 

plate on the left and right side engine 

struts. Accomplishing the actions 

specified in the service information is 

intended to adequately address the 

unsafe condition. 

FAA’s Determination and Requirements 

of the Proposed AD 

We have evaluated all pertinent 

information and identified an unsafe 

condition that is likely to develop on 


ebenthall on PRODPC61 with PROPOSALS
Federal Register / Vol. 73, No. 27 / Friday, February 8, 2008 / Proposed Rules 7485 

other airplanes of the same type design. 

For this reason, we are proposing this 

AD, which would supersede AD 99–04–

11 and require accomplishing the 

actions specified in the service bulletin 

described previously. This proposed AD 

would also add Model 737–700C and 

–900 series airplanes to the 

applicability. 

Costs of Compliance 

There are about 2,148 airplanes of the 

affected design in the worldwide fleet. 

This proposed AD would affect about 

740 airplanes of U.S. registry. The 

following table provides the estimated 

costs for U.S. operators to comply with 

this proposed AD. The average labor 

rate is $80 per work hour.

Installation (new proposed action) ................................................................... 4 $4,730 $5,050 $3,737,000

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 

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 that the 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); and 

3. 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket. See the ADDRESSES section 

for a location to examine the regulatory 

evaluation. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Safety. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part
