The Proposed Amendment

Accordingly, pursuant to the

authority delegated to me by the

Administrator, the Federal Aviation

Administration proposes to amend 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 USC 106(g), 40101, 40113,

44701.

§ 39.13 [Amended]

2. Section 39.13 is amended by

adding the following new airworthiness

directive:

Boeing: Docket 95–NM–244–AD.

Applicability: All Model 767 series

airplanes, certificated in any category.

Note 1: This AD applies to each airplane

identified in the preceding applicability

provision, regardless of whether it has been

otherwise 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 use the authority

provided in paragraph (d) of this AD to

request approval from the FAA. This

approval may address either no action, if the

current configuration eliminates the unsafe

condition; or different actions necessary to

address the unsafe condition described in

this AD. Such a request should include an

assessment of the effect of the changed

configuration on the unsafe condition

addressed by this AD. In no case does the

presence of any modification, alteration, or

repair remove any airplane from the

applicability of this AD.

Compliance: Required as indicated, unless

accomplished previously.

To prevent reduced controllability of the

airplane and damage to or cracking of the

leading edge slats or the fixed leading edge

of the wing, accomplish the following:

(a) Within 500 hours time-in-service after

the effective date of this AD, unless

previously accomplished within the last

3,000 hours time-in-service prior to the

effective date of this AD: Perform a visual

inspection to verify proper clearance of the

overtravel stop, in accordance with the

Boeing 767 Airplane Maintenance Manual

(AMM), Chapter 27–81–20.

(1) If proper clearance exists, repeat the

inspection for proper clearance thereafter at

intervals not to exceed 6,000 hours time-inservice or 18 months, whichever occurs later.

(2) If clearance exists, but is incorrect, at

the next convenient maintenance interval,

but no later than 500 flight hours after

accomplishment of the inspection, adjust the

stop clearance for the slats in accordance

with the AMM. Repeat the inspection for

proper clearance thereafter at intervals not to

exceed 6,000 hours time-in-service or 18

months, whichever occurs later.

(3) If no clearance exists (i.e., stop contact),

prior to further flight, adjust the stop

clearance for the slats in accordance with the

AMM. After the adjustment, within 3,000

hours time-in-service or 1,500 flight cycles

after accomplishing the inspection required

by paragraph (a) of this AD, whichever

occurs later, replace the rotary actuator and

adjacent offset gearbox in accordance with

the AMM. After replacement, repeat the

inspection for proper clearance at intervals

not to exceed 6,000 hours time-in-service or

18 months, whichever occurs later.

(b) Within 500 hours time-in-service after

the effective date of this AD, unless

previously accomplished within the last

3,000 hours time-in-service prior to the

effective date of this AD, perform a visual

inspection to detect external signs of internal

corrosion of the rotary actuator of the

outboard leading edge slat, in accordance

with the Boeing 767 Airplane Maintenance

Manual (AMM), Chapter 27–81–20.

(1) If no sign of internal corrosion is

detected, accomplish paragraph (b)(1)(i) or

(b)(1)(ii) of this AD, as applicable.

(i) For airplanes on which a rotary actuator

having part number (P/N) 256T2120–3 or

earlier is installed: Within 4,000 flight hours

after the effective date of this AD, replace

that rotary actuator with a new rotary

actuator having P/N 256T2120–5 or later.

After replacement, repeat the inspection of

the rotary actuator at intervals not to exceed

6,000 flight hours or 18 months, whichever

occurs later.

(ii) For airplanes on which a rotary

actuator having P/N 256T2120–5 or later is

installed: Repeat the inspection of the rotary

actuator thereafter at intervals not to exceed

6,000 flight hours or 18 months, whichever

occurs later.

(2) If any sign of internal corrosion is

detected, accomplish paragraph (b)(2)(i) or

(b)(2)(ii) of this AD, as applicable.

(i) For airplanes on which a rotary actuator

having part number (P/N) 256T2120–3 or

earlier is installed: Within 4,000 flight hours

after the effective date of this AD, replace

that rotary actuator with a new rotary

actuator having P/N 256T2120–5 or later.

After replacement, repeat the inspection of

the rotary actuator at intervals not to exceed

6,000 flight hours or 18 months, whichever

occurs later.

(ii) For airplanes on which a rotary

actuator having P/N 256T2120–5 or later is

installed: Within 6,000 flight hours or 18

months after accomplishing the initial

inspection required by paragraph (b) of this

AD, replace that rotary actuator with a new

rotary actuator having P/N 256T2120–5 or

later. After replacement, repeat the

inspection required of the rotary actuator at

intervals not to exceed 6,000 flight hours or

18 months, whichever occurs later.

(c) Within 500 hours time-in-service after

the effective date of this AD, unless

previously accomplished within the last

3,000 hours time-in-service prior to the

effective date of this AD, perform a visual

inspection to verify proper installation

(including loose bolts and missing lockwires)

of the control rods of the outboard leading

edge slats, in accordance with the Boeing 767

Airplane Maintenance Manual (AMM),

Chapter 27–81–20.

(1) If all control rods are installed properly,

repeat the inspection to verify proper

installation thereafter at intervals not to

exceed 6,000 flight hours or 18 months,

whichever occurs later.

(2) If any bolt is loose or any lockwire

missing, prior to further flight, tighten the

bolt or install a new lockwire, in accordance

with the AMM. Repeat the inspection to

verify proper installation thereafter at

intervals not to exceed 6,000 flight hours or

18 months, whichever occurs later.

(d) 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,

Transport Airplane Directorate. 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 2: Information concerning the

existence of approved alternative methods of

compliance with this AD, if any, may be

obtained from the Seattle ACO.

(e) 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.

The Proposal

The FAA is considering an

amendment to part 71 of the Federal

Aviation Regulations (14 CFR part 71) to

establish Class E5 airspace at Bigfork

Municipal Airport, Bigfork, MN, to

accommodate a Nondirectional Radio

Beacon (NDB) to serve Runway 15.

Controlled airspace extending upward

from 700 to 1200 feet AGL is needed to

contain aircraft executing the approach.

The intended effect of this action is to

provide segregation of aircraft using

instrument approach procedures in

instrument conditions from other

aircraft operating in visual weather

conditions. The area would be depicted

on appropriate aeronautical charts

thereby enabling pilots to

circumnavigate the area or otherwise

comply with IFR procedures. Class E

airspace designations for airspace areas

extending upward from 700 feet or more

above the surface of the earth are

published in paragraph 6005 of FAA

Order 7400.9C dated August 17, 1995,

and effective September 16, 1995, which

is incorporated by reference in 14 CFR

71.1. The Class E airspace designation

listed in this document would be

published subsequently in the Order.

The FAA has determined that this

proposed regulation only involves an

established body of technical

regulations for which frequent and

routine amendments are necessary to

keep them operationally current.

Therefore this, proposed regulation—(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)

does not warrant preparation of a

Regulatory Evaluation as the anticipated

impact is so minimal. Since this is a

routine matter that will only affect air

traffic procedures and air navigation, it

is certified that this proposed rule will

not have a significant economic impact

on a substantial number of small entities

under the criteria of the Regulatory

Flexibility Act.

Accordingly, pursuant to the

authority delegated to me, the Federal

Aviation Administration proposes to

amend part 71 of the Federal Aviation

Regulations (14 CFR part 71) as follows:
