AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts a

new airworthiness directive (AD),

applicable to certain Boeing Model 767–

200 and –300 series airplanes, that

requires replacement of the existing

potable water fill line tube with a new

hose. This action is necessary to prevent

fracture of a clamshell coupling on the

potable water fill line, which could

cause water to flow into the aft cargo

compartment. A large amount of water

in the cargo compartment could cause

large shifts in the airplane’s center of

gravity, which could result in reduced

controllability of the airplane. This

action is intended to address the

identified unsafe condition.

DATES: Effective June 1, 2001.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of June 1,

2001.

ADDRESSES: The service information

referenced in this AD may be obtained

from Boeing Commercial Airplane

Group, P.O. Box 3707, Seattle,

SUPPLEMENTARY INFORMATION: A

proposal to amend part 39 of the Federal

Aviation Regulations (14 CFR part 39) to

include an airworthiness directive (AD)

that is applicable to certain Boeing

Model 767–200 and –300 series

airplanes was published in the Federal

Register on December 21, 2000 (65 FR

80390). That action proposed to require

replacement of the existing potable

water fill line tube with a new hose.

Comments

Interested persons have been afforded

an opportunity to participate in the

making of this amendment. Due

consideration has been given to the

comments received.

Support for the Proposal

One commenter supports the

proposed rule, and two other

commenters state no objection to the

proposed rule because they do not

operate airplanes subject to the

proposed rule.

Request To Limit Applicability

One commenter requests that the FAA

revise the applicability of the proposed

AD to state that the actions are only

required for airplanes equipped with a

potable water system. The commenter

states that it operates several airplanes

included in the applicability statement

of the proposed rule that are not

equipped with a potable water system.

The unsafe condition addressed by the

proposed AD may occur when water is

being pumped into the airplane to fill

the potable water system. However, if

the airplane has no potable water

system, there is no cause for water to be

pumped into the airplane. Thus,

airplanes without a potable water

system would not be subject to the

unsafe condition. The FAA concurs, and

has revised the applicability statement

of this AD to include only Boeing Model

767–200 and –300 series airplanes listed

in Boeing Alert Service Bulletin 767–

38A0057, dated July 13, 2000, that are

equipped with a potable water system.

Conclusion

After careful review of the available

data, including the comments noted

above, the FAA has determined that air

safety and the public interest require the

adoption of the rule with the change

previously described. The FAA has

determined that this change will neither

increase the economic burden on any

operator nor increase the scope of the

AD.

21072 Federal Register / Vol. 66, No. 82 / Friday, April 27, 2001 / Rules and Regulations

Cost Impact

There are approximately 159 Model

767–200 and –300 series airplanes of the

affected design in the worldwide fleet.

The FAA estimates that 18 airplanes of

U.S. registry will be affected by this AD,

that it will take approximately 1 work

hour per airplane to accomplish the

required actions, and that the average

labor rate is $60 per work hour.

Required parts will cost approximately

$482 per airplane. Based on these

figures, the cost impact of the AD on

U.S. operators is estimated to be $9,756,

or $542 per airplane.

The cost impact figure discussed

above is based on assumptions that no

operator has yet accomplished any of

the requirements of this AD action, and

that no operator would accomplish

those actions in the future if this AD

were not adopted. The cost impact

figures discussed in AD rulemaking

actions represent only the time

necessary to perform the specific actions

actually required by the AD. These

figures typically do not include

incidental costs, such as the time

required to gain access and close up,

planning time, or time necessitated by

other administrative actions.

Regulatory Impact

The regulations adopted herein will

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. Therefore, it is

determined that this final rule does not

have federalism implications under

Executive Order 13132.

For the reasons discussed above, I

certify that this action (1) is not a

‘‘significant regulatory action’’ under

Executive Order 12866; (2) is not a

‘‘significant rule’’ under 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. A final evaluation has

been prepared for this action and it is

contained in the Rules Docket. A copy

of it may be obtained from the Rules

Docket at the location provided under

the caption ADDRESSES.

certificated in any category.

Note 1: This AD applies to each airplane

identified in the preceding applicability

provision, regardless of whether it has been

modified, altered, or repaired in the area

subject to the requirements of this AD. For

airplanes that have been modified, altered, or

repaired so that the performance of the

requirements of this AD is affected, the

owner/operator must request approval for an

alternative method of compliance in

accordance with paragraph (c) of this AD.

The request should include an assessment of

the effect of the modification, alteration, or

repair on the unsafe condition addressed by

this AD; and, if the unsafe condition has not

been eliminated, the request should include

specific proposed actions to address it.

Compliance: Required as indicated, unless

accomplished previously.

To prevent fracture of a clamshell coupling

on the potable water fill line, which could

cause a large amount of water to flow into the

aft cargo compartment, and result in large

shifts in the airplane’s center of gravity and

consequent reduced controllability of the

airplane, accomplish the following:
