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. 

We prepared an economic evaluation 

of the estimated costs to comply with 

this AD. See the DMS to examine the 

economic evaluation. 

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.

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 

removing Amendment 39–13870 (69 FR 

67805, November 22, 2004), and by 

adding a new airworthiness directive 

(AD), Amendment 39–14739, to read as 

follows: 

2006–18–01 MD Helicopters, Inc.: 

Amendment 39–14739. Docket No. 

FAA–2006–24631; Directorate Identifier 

2005–SW–01–AD. Supersedes AD 2004–

23–15, Amendment 39–13870, Docket 

No. FAA–2004–19613, Directorate 

Identifier 2004–SW–38–AD. 

Applicability: Model MD900 helicopters, 

with a Notar fan system that has a tensiontorsion (TT) strap, part number (P/N) 

900R3442009–103, 900R6442009–103, 

900R3442009–101, or 500N5311–5, installed, 

certificated in any category. 

Compliance: Required as indicated. 

To prevent failure of a TT strap in the 

Notar fan system, loss of directional control, 

and subsequent loss of control of the 

helicopter, accomplish the following: 

(a) Before further flight, unless 

accomplished previously, for TT Straps, P/N 

900R3442009–103 and 900R6442009–103, 

reduce the life limit from 3,034 to 2,500 

hours time-in-service (TIS) and revise the life 

limit on the component history card or 

equivalent record to reflect this reduced 

retirement life. 

(b) Within 10 hours TIS, unless 

accomplished previously, for any TT strap 

that has accumulated 1,190 or more hours 

TIS, and then at intervals not to exceed 300 

hours TIS, remove the TT strap from the 

helicopter and do a visual and an X-ray 

inspection in accordance with the Inspection 

Instructions, paragraph 2.B.(1). through (5)., 

and Figures 1 and 2 of MD Helicopters 

Service Bulletin SB900–095, dated November 

3, 2004 (SB). Replace any unairworthy TT 

strap before further flight. 

(c) Before the TT strap accumulates 1,200 

hours TIS, for any TT strap with less than 

1,190 hours TIS, and then at intervals not to 

exceed 300 hours TIS, remove the TT strap 

from the helicopter and do a visual and an 

X-ray inspection in accordance with the 

Inspection Instructions, paragraph 2.B.(1). 

through (5)., and Figures 1 and 2 of the SB. 

Replace any unairworthy TT strap before 

further flight. 

(d) The X-ray inspection of the TT strap 

must be performed by a Level II or higher Xray technician who is qualified under the 

guidelines established by MIL–STD–410E, 

ATA Specification 105, AIA–NAS–410, or an 

FAA-accepted equivalent for qualification 

standards. 

(e) This AD revises the Airworthiness 

Limitations section of the maintenance 

manual by reducing the life limit of the TT 

straps, P/N 900R3442009–103 and 

900R6442009–103, from 3,034 hours TIS to 

2,500 hours TIS. Additionally, this AD 

revises the Airworthiness Limitations section 

of the maintenance manual by adding 

repetitive inspection requirements at 

intervals not to exceed 300 hours TIS for TT 

straps, P/N 900R3442009–103, 

900R6442009–103, 900R3442009–101, and 

500N5311–5, that have 1,200 or more hours 

TIS until the TT strap reaches its retirement 

life. 

(f) To request a different method of 

compliance or a different compliance time 

for this AD, follow the procedures in 14 CFR 

39.19. Contact the Manager, Los Angeles

Amendment to Class D Airspace; 

Provo, UT 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This action amends the Class 

D airspace area at Provo, UT. A review 

of the legal description revealed that it 

does not reflect the current airport 

reference point (ARP) for Provo 

Municipal Airport. 

EFFECTIVE DATE: 0901 UTC, November 

23, 2006. The Director of the Federal 

Register approves this incorporation by 

reference action under 14 CFR 71.1, 

subject to the annual revision of FAA 

Order 7400.9 and publication of 

conforming amendments.

SUPPLEMENTARY INFORMATION: 

History 

An examination of the Class D 

airspace area designation at Provo, UT, 

revealed that the legal description did 


cprice-sewell on PROD1PC66 with RULES
Federal Register / Vol. 71, No. 167 / Tuesday, August 29, 2006 / Rules and Regulations 51097 

not reflect the current ARP for Provo 

Municipal Airport. This action will 

change the longitude in the ARP for the 

airport. Class D airspace areas are 

published in Paragraph 5000 of FAA 

Order 7400.9N dated September 1, 2005, 

and effective September 15, 2005, which 

is incorporated by reference in 14 CFR 

71.1. The Class D airspace designation 

listed in this document will be 

published subsequently in the Order. 

The Rule 

This action amends Title 14 Code of 

Federal Regulations (14 CFR) part 71 by 

amending the longitude in the legal 

description of Provo Municipal 

Airport’s ARP. Accordingly, since this 

action only involves a change in the 

airport’s legal description of the Provo, 

UT, Class D airspace area, and does not 

involve a change in the dimensions or 

operating requirements of that airspace, 

notice and public procedure under 5 

U.S.C. 553(b) are unnecessary. The FAA 

has determined that this regulation only 

involves an established body of 

technical regulations for which frequent 

and routine amendments are necessary 

to keep them operationally current. 

Therefore, this regulation: (1) Is not a 

‘‘significant regulatory action’’ under 

Executive Order 12866; (2) is not a 

‘‘significant rule’’ under Department of 

Transportation 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.

SUPPLEMENTARY INFORMATION: 

History 

On August 1, 2006, a final rule was 

published in the Federal Register (71 

FR 43355), Docket No. FAA–2006–

24234; Airspace Docket No. 06–AWP–5. 

This rule amended the Class E airspace 

area at Provo, UT, revising the legal 

description ARP to match that of the 

Provo, UT, Class D airspace. 

Unfortunately, the Class D airport ARP 

was also incorrect in that it did not 

match the current ARP in the National 

Airspace System Resource Database. 

The correction to the Class E ARP is 

made in this docket. In addition, the 

two references to FAA Order 7400.9O, 

dated September 1, 2006, and effective 

September 15, 2006, are corrected to 

read FAA Order 7400.9N, dated 

September 1, 2005, and effective 

September 15, 2005, which is current as 

of this date. Two editorial changes are 

made; in the Summary, the word 

amends replaces attends, and in the 

legal description, the term Class E 

replaces Class D airspace. 

Correction to Final Rule 

■ Accordingly, pursuant to the authority 

delegated to me, the changes as 

described above are corrected, and the 

legal description for Provo, UT, as 

published in the Federal Register on 

August 1, 2006, (71 FR 43355), and 

incorporated by reference in 14 CFR 

71.1, is corrected as follows:
