AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain Boeing Model 757–200 and 757–

300 series airplanes. This proposed AD 

would require installing a copper 

bonding jumper between a ground and 

the clamp on the tube of the forward 

and aft gray water composite drain 

masts. This proposed AD results from a 

report of charred insulation blankets 

and burned wires around the forward 

gray water composite drain mast found 

during an inspection of the forward 

cargo compartment on a Model 767–

300F airplane. We are proposing this 

AD to prevent a fire near a composite 

drain mast and possible disruption of 

the electrical power system due to a 

lightning strike on a composite drain 

mast, which could result in the loss of 

several functions essential for safe 

flight. 

DATES: We must receive comments on 

this proposed AD by July 2, 2007. 

ADDRESSES: Use one of the following 

addresses to submit comments on this 

proposed AD.

Discussion 

We have received a report indicating 

that, during an inspection of the forward 

cargo compartment on a Model 767–

300F airplane, an operator found 

charred insulation blankets and burned 

wires around the forward gray water 

composite drain mast. Additional 

charring on the insulation blankets was 

noticed several feet away along the 

routing of the drain mast’s ground wire 

and power wires. Analysis of the 

damaged parts revealed that a lightning 

strike on the composite drain mast 

caused the damage to the wires and 

insulation blankets. This condition, if 

not corrected, could cause disruption of 

electrical power and fire and heat 

damage to equipment in the event of a 

lightning strike on the composite drain 

mast, which could result in the loss of 

several functions essential for safe 

flight. 

A design review of the gray water 

composite drain mast installation on 

Model 737NG, 757, 767, and 777 

airplanes revealed that the installation 

of a heavier bonding jumper is 

necessary to provide adequate lightning 

protection to the gray water composite 

drain mast installation. The subject area 

on Model 757 airplanes is almost 

identical to that on the affected Model 

767–300F airplane. Therefore, Model 

757 airplanes may be subject to the 

unsafe condition revealed on the Model 

767–300F airplane. We are currently 

considering additional rulemaking to 

address the identified unsafe condition 

on Model 737NG, 767, and 777 

airplanes. 

Relevant Service Information 

We have reviewed Boeing Special 

Attention Service Bulletin 757–30–

0024, dated July 24, 2006. The service 

bulletin describes procedures for 

installing a 135-ampere copper bonding 

jumper between a ground and the clamp 

on the tube of the forward and aft gray 

water composite drain masts. 

Above the waste-water access panel, 

the installation includes: 

• Replacing the existing ground 

bracket with a new ground bracket; 

• Installing a bonding jumper 

between the ground bracket and the 

clamp on the tube of the forward gray 

water composite drain mast; 

• Doing a drain mast installation test; 

and 

• Measuring the resistance of the 

bonding jumper installation. 

In the bulk cargo compartment, the 

installation includes: 

• Installing a new ground bracket; 

• Installing a bonding jumper 

between the ground bracket and the 

clamp on the tube of the aft gray water 

composite drain mast; 

• Doing a drain mast installation test; 

and 

• Measuring the resistance of the 

bonding jumper installation. 

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 exist or 

develop on other airplanes of this same 

type design. For this reason, we are 

proposing this AD, which would require 

accomplishing the actions specified in 

the service information described 

previously. 

Costs of Compliance 

There are about 83 airplanes of the 

affected design in the worldwide fleet. 

The following table provides the 

estimated costs for U.S. operators to 

comply with this proposed AD. 

ESTIMATED COSTS

Action Work hours Average labor 

rate per hour Parts Cost per airplane 

Number of 

U.S.-registered 

airplanes 

Fleet cost 

Bonding jumper installation 2 $80 $353, per kit (1 kit per drain

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.

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

2. The Federal Aviation 

Administration (FAA) amends § 39.13 

by adding the following new 

airworthiness directive (AD): 

Boeing: Docket No. FAA–2007–28160; 

Directorate Identifier 2007–NM–006–AD. 

Comments Due Date 

(a) The FAA must receive comments on 

this AD action by July 2, 2007.

(d) This AD results from a report of charred 

insulation blankets and burned wires around 

the forward gray water composite drain mast 

found during an inspection of the forward 

cargo compartment on a Model 767–300F 

airplane. We are issuing this AD to prevent 

a fire near a composite drain mast and 

possible disruption of the electrical power 

system due to a lightning strike on a 

composite drain mast, which could result in 

the loss of several functions essential for safe 

flight.
