30550 Federal Register / Vol. 61, No. 117 / Monday, June 17, 1996 / Proposed Rules

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), 40113, and

44701.

§ 39.13 [Amended]

2. Section 39.13 is amended by

removing Amendment 39–1055 (35 FR

12532, August 6, 1970), and

Amendment 39–672 (33 FR 15543,

October 19, 1968), and by adding a new

airworthiness directive (AD), to read as

follows:

Schweizer Aircraft Corporation and Hughes

Helicopters, Inc.: Docket No. 94–SW–

17–AD. Supersedes AD 68–21–05,

Amendment 39–1055 and Amendment

39–672.

Applicability: Model 269A helicopters,

serial numbers (S/N) 0011 through 1109,

Model 269A–1 helicopters, S/N 0001 through

0041, Model 269B, S/N 0001 through 0444,

and Model TH–55A, with main rotor thrust

bearing, part number (P/N) 269A5050–50,

–51 or –73, installed, certified in any

category.

Note 1: This AD applies to each helicopter

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

helicopters 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 (g) 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 helicopter

from the applicability of this AD.

Compliance: Required within 25 hours

time-in-service (TIS) after the effective date

of this AD, unless accomplished previously.

To prevent failure of the main rotor thrust

bearing, loss of the main rotor, and

subsequent loss of control of the helicopter,

accomplish the following:

(a) From available helicopter records,

determine the TIS of the appropriate main

rotor thrust bearing (bearing), part number

(P/N) 269A5050–50, 269A5050–51, or

269A5050–73.

(1) If the TIS on the bearing, P/N

269A5050–50 or –51, equals or exceeds 300

hours TIS, replace the bearing before further

flight.

(2) If the TIS on the hearing, P/N

269A5050–50 or –51, equals or exceeds 275

hours TIS, retire the bearing from service

within 25 hours TIS after the effective date

of this AD.

(b) Inspect bearing, P/N 269A5050–50 or

–51, for rotational roughness, corrosion,

inadequate lubrication, physical damage,

moisture or inadequate drainage due to

build-up of zinc chromate paste in

accordance with Step II, paragraph b of

Schweizer Service Notice (SSN) No. N–59,

dated October 9, 1968.

(1) If bearing rotational roughness,

corrosion, inadequate lubrication, physical

damage, moisture or inadequate drainage due

to build-up of zinc chromate paste is found,

replace the bearing with an airworthy

bearing.

(2) If no bearing rotational roughness,

corrosion, lack of lubrication, physical

damage, moisture or inadequate drainage due

to build-up of zinc chromate paste is found,

thereafter, inspect the bearing in accordance

with this paragraph upon attaining an

additional 150 hours TIS.

(3) For replacement bearings, inspect in

accordance with this paragraph upon

attaining 150 hours TIS, unless the bearing

reaches its 300 hour TIS retirement life limit

prior to this inspection.

(c) For bearing, P/N 269A5050–73:

(1) Inspect the bearing for corrosion, rust,

freedom of rotation, looseness, binding,

nicks, burrs, cracks and lubrication.

Thereafter, inspect the bearing at intervals

not to exceed 600 hours TIS.

(2) As necessary, repack the bearing cavity

in accordance with Schweizer Aircraft

Corporation CKP–C–41 ‘‘Installation

Instructions For 269 Series Helicopters, SA–

269K–057–1 Main Rotor Thrust Bearing Kit,’’

dated June 9, 1994.

(d) This AD establishes a retirement life of

300 hours TIS for bearings, P/Ns 269A5050–

50 and –51 and a retirement life of 3,000

hours TIS for bearing, P/N 2695050–73.

However, bearings, P/Ns 269A5050–50 and

–51, with at least 275 hours TIS but less than

300 hours TIS on the effective date of this

AD, need not be retired until or before the

accumulation of an additional 25 hours TIS

after the effective date of this AD.

(e) Inspect the thrust bearing nut (nut), P/

N 269A1306–5, for corrosion and physical

damage and determine whether the nut has

been modified in accordance with Step III of

SSN No. N–59, dated October 9, 1968.

(1) If corrosion or physical damage is

found, replace the nut with an airworthy nut

that has been modified in accordance with

Step III of SSN No. N–59, dated October 9,

1968.

(2) If the nut has not been modified,

modify the nut in accordance with Step III

of SSN No. N–59, dated October 9, 1968.

(f) Inspect the interior of the main rotor

mast (mast) for corrosion, physical damage,

foreign materials, moisture or inadequate

drainage due to a buildup of zinc chromate

paste and determine whether the mast has

been modified in accordance with Step II of

SSN No. N–59, dated October 9, 1968 to

install a drain hole.

(1) If corrosion or physical damage is

found, replace the mast with an airworthy

mast that has been modified in accordance

with Step III of SSN No. N–59, dated October

9, 1968.

(2) If the interior of the mast has foreign

materials, moisture or inadequate drainage

due to a buildup of zinc chromate past, clean

the area with a suitable solvent in accordance

with Step II of SSN No. N–59, dated October

9, 1968.

(3) If the mast has not been modified,

modify the mast in accordance with Step III

of SSN No. N–59, dated October 9, 1968.

(g) 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, New York

Aircraft Certification Office. Operators shall

submit their requests through an FAA

Principal Maintenance Inspector, who may

concur or comment and then send it to the

Manager, New York Aircraft Certification

Office.

Note 2: Information concerning the

existence of approved alternative methods of

compliance with this AD, if any, may be

obtained from the New York Aircraft

Certification Office.

(h) 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 helicopter

to a location where the requirements of this

AD can be accomplished.

The Proposal

The FAA is proposing to amend 14

CFR part 71 by establishing two Federal

Airways, V–603 from Pulaski, VA, to

Columbia, SC, and V–605 from Holston

Mountain, TN, to Spartanburg, SC.

Presently, aircraft transitioning through

the terminal airspace at Charlotte/

Douglas International Airport operating

at or below 12,500 feet are being radar

vectored west of that airport to provide

for a safe and efficient operation.

Establishing V–603 and V–605 would

provide a published route through the

Charlotte terminal airspace, expedite the

flow of air traffic, and reduce the

workload for pilots and controllers.

Domestic Very High Frequency

Omnidirectional Range Federal airways

are published in paragraph 6010(a) 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 airways 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. It,

therefore—(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 rule,

when promulgated, will not have a

significant economic impact on a

substantial number of small entities

under the criteria of the Regulatory

Flexibility Act.

List of Subjects in 14 CFR Part 71

Airspace, Incorporation by reference,

Navigation (air).

The Proposed Amendment

In consideration of the foregoing, the

Federal Aviation Administration

proposes to amend 14 CFR part 71 as
