Airworthiness Directives; Boeing

Model 747–400 Series Airplanes

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts a

new airworthiness directive (AD),

applicable to certain Boeing Model 747–

400 series airplanes, that requires an

inspection to detect miswiring of diodes

in the heating system of the pitot static

probes, and corrective action, if

necessary. The actions specified by this

AD are intended to prevent reduced

power to the heating system of the pitot

static probes, leading to ice

accumulation on the pitot static probes,

which could result in erroneous

airspeed or altitude indications to the

flight crew, and consequent reduced

operational safety in all phases of flight.

This action is intended to address the

identified unsafe condition.

DATES: Effective July 25, 2001.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of July 25,

2001.

ADDRESSES: The service information

referenced in this AD may be obtained

from Boeing Commercial Airplane

Group, P.O. Box 3707, Seattle,

Washington 98124–2207. This

information may be examined at the

Federal Aviation Administration (FAA),

SUPPLEMENTARY INFORMATION: A Notice

of Proposed Rulemaking (NPRM) to

amend part 39 of the Federal Aviation

Regulations (14 CFR part 39) to include

an airworthiness directive (AD)

applicable to certain Boeing Model 747–

400 series airplanes was published in

the Federal Register on February 21,

2001 (66 FR 10972). That action

proposed to require an inspection to

detect miswiring of diodes in the

heating system of the pitot static probes,

and corrective action, if necessary.

Editorial Change

The compliance time for rewiring of

any miswiring, detected during the

special detailed inspection required by

paragraph (a) of this AD, was

inadvertently omitted. Paragraph (a) of

this AD has been changed to require

rewiring of any miswiring prior to

further flight.

Comments

Interested persons have been afforded

an opportunity to participate in the

making of this amendment. Due

consideration has been given to the

single comment received.

The commenter supports the

proposed rule.

Conclusion

After careful review of the available

data, including the comment noted

above, the FAA has determined that air

safety and the public interest require the

adoption of the rule with the change

described previously. The FAA has

determined that this change will neither

increase the economic burden on any

operator nor increase the scope of this

AD.

Cost Impact

There are approximately 497 Model

747–400 series airplanes of the affected

design in the worldwide fleet. The FAA

estimates that 69 airplanes of U.S.

registry will be affected by this AD, that

it will take approximately 2 work hours

per airplane to accomplish the required

actions, and that the average labor rate

is $60 per work hour. Based on these

figures, the cost impact of the AD on

U.S. operators is estimated to be $8,280,

or $120 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)

Federal Register / Vol. 66, No. 119 / Wednesday, June 20, 2001 / Rules and Regulations 33017

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.

Adoption of the Amendment

Accordingly, pursuant to the

authority delegated to me by the

Administrator, the Federal Aviation

Administration amends part 39 of the

Federal Aviation Regulations (14 CFR

part 39) as follows:

PART 39—AIRWORTHINESS

DIRECTIVES

1. The authority citation for part 39

continues to read as follows:

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

§ 39.13 [Amended]

2. Section 39.13 is amended by

adding the following new airworthiness

directive:

2001–12–14 Boeing: Amendment 39–12269.

Docket 2000–NM–320–AD.

Applicability: Model 747–400 series

airplanes, as listed in Boeing Alert Service

Bulletin 747–30A2078, Revision 1, dated

November 16, 2000; 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 (b) 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 reduced power to the heating

system of the pitot static probes, leading to

ice accumulation on the pitot static probes,

which could result in erroneous airspeed or

altitude indications to the flight crew, and

consequent reduced operational safety in all

phases of flight, accomplish the following:

Inspection

(a) Within 15 months after the effective

date of this AD, perform a special detailed

inspection to detect miswiring of diodes in

the heating system of the pitot static probes

by using a multimeter to verify continuity

between certain relay sockets, absence of a

diode between certain relay sockets, and

diode orientation between certain relay

sockets, per Boeing Alert Service Bulletin

747–30A2078, Revision 1, dated November

16, 2000. If any miswiring is found, prior to

further flight, rewire per Boeing 747–400

Wiring Diagrams 30–31–11 and 30–31–21, as

referenced in the service bulletin.

Note 2: Inspections accomplished prior to

the effective date of this AD per Boeing Alert

Service Bulletin 747–30A2078, dated August

24, 2000, are considered acceptable for

compliance with the applicable action

specified in this amendment.

Note 3: For the purposes of this AD, a

special detailed inspection is defined as: ‘‘An

intensive examination of a specific item(s),

installation, or assembly to detect damage,

failure, or irregularity. The examination is

likely to make extensive use of specialized

inspection techniques and/or equipment.

Intricate cleaning and substantial access or

disassembly procedures may be required.’’

Alternative Methods of Compliance

(b) An alternative method of compliance or

adjustment of the compliance time that

provides an acceptable level of safety may be

used if approved by the Manager, Seattle

Aircraft Certification Office (ACO), FAA.

Operators shall submit their requests through

an appropriate FAA Principal Maintenance

Inspector, who may add comments and then

send it to the Manager, Seattle ACO.

Note 4: Information concerning the

existence of approved alternative methods of

compliance with this AD, if any, may be

obtained from the Seattle ACO.

Special Flight Permits

(c) Special flight permits may be issued in

accordance with sections 21.197 and 21.199

of the Federal Aviation Regulations (14 CFR

21.197 and 21.199) to operate the airplane to

a location where the requirements of this AD

can be accomplished.

Incorporation by Reference

(d) Except as provided by paragraph (a) of

this AD, The actions shall be done in

accordance with Boeing Alert Service

Bulletin 747–30A2078, Revision 1, dated
