AGENCY: Federal Aviation 

Administration, DOT. 

ACTION: Final rule. 

SUMMARY: This amendment adopts a 

new airworthiness directive (AD) for the 

specified restricted category typecertificated helicopters. The AD requires 

a review of the helicopter records to 

determine the Commercial and 

Government Entity (CAGE) code of the 

tail rotor (T/R) slider. If the T/R slider 

is FAA approved or has a certain legible 

CAGE code, this AD requires no further 

action. If you cannot determine whether 

the T/R slider is FAA approved and it 

has no stamped CAGE code, an illegible 

stamped CAGE code, or an affected 

CAGE code, the AD also requires, before 

further flight and at specified intervals, 

magnaflux inspecting the T/R slider for 

a crack. If a crack is found, the AD 

requires, before further flight, replacing 

the T/R slider with an airworthy T/R 

slider. The AD also requires replacing 

the T/R slider with an airworthy T/R 

slider on or before accumulating 1,000 

hours time-in-service (TIS) or on or 

before 12 months, whichever occurs 

first. This amendment is prompted by 

two accidents attributed to sub-standard 

T/R sliders that failed during flight. The 

actions specified by this AD are 

intended to prevent failure of a T/R 

slider, loss of T/R control, and 

subsequent loss of control of the 

helicopter. 

DATES: Effective October 16, 2006.

SUPPLEMENTARY INFORMATION: A 

proposal to amend 14 CFR part 39 to 

include an AD for the specified 

restricted category type-certificated 

helicopters was published in the 

Federal Register on June 22, 2006 (71 

FR 35840). That action proposed to 

require a review of the helicopter 

records to determine the CAGE code of 

the T/R slider. If the T/R slider is FAA 

approved or has a certain legible CAGE 

code, the AD proposed no further 

action. If you cannot determine whether 

the T/R slider is FAA approved or if it 

has an illegible CAGE code or CAGE 

Code 15716 or 26098, the AD proposed, 

before further flight and at specified 

intervals, magnaflux inspecting the T/R 

slider for a crack. If a crack is found, the 

AD proposed, before further flight, 

replacing the T/R slider with an 

airworthy T/R slider. The AD also 

proposed replacing the T/R slider that 

has an illegible CAGE code or Code 

15716 or 26098 with an airworthy T/R 

slider on or before accumulating 1,000 

hours TIS or on or before 12 months, 

whichever occurs first. 

Interested persons have been afforded 

an opportunity to participate in the 

making of this amendment. No 

comments were received on the 

proposal or the FAA’s determination of 

the cost to the public. The FAA has 

determined that air safety and the 

public interest require the adoption of 

the rule as proposed. 

We estimate that this AD will affect 

75 helicopters of U.S. registry and that 

it will take about: 

• 1 work hour to review the 

helicopter records and 2 work hours to 

remove and replace the T/R slider for a 

total of 3 work hours per helicopter to 

determine the CAGE code for each 

helicopter in the fleet; 

• 3 work hours for each magnaflux 

inspection with a total of 24 such 

inspections on each of 10 helicopters 

based on 600 hours TIS per year; and 

• 2 work hours to replace the T/R 

slider with 10 helicopters needing the 

T/R slider replaced. 

The average labor rate is $65 per work 

hour. Required parts will cost about 

$825 for each T/R slider. Based on these 

figures, we estimate the total cost 

impact of the AD on U.S. operators to 

be $70,975 ($195 per helicopter to 

determine the CAGE code and $5,635 

per helicopter for repetitively inspecting 

and ultimately replacing the T/R slider 

on 10 helicopters). 

Regulatory Findings 

We have determined that this AD will 

not have federalism implications under 

Executive Order 13132. This AD 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. 

For the reasons discussed above, I 

certify that the regulation: 

1. Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866; 

2. Is not a ‘‘significant rule’’ under the 

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. 

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 


bjneal on PROD1PC71 with RULES
53320 Federal Register / Vol. 71, No. 175 / Monday, September 11, 2006 / Rules and Regulations 

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.

FAA–2006–25097; Directorate Identifier 

2005–SW–19–AD. 

Applicability: Model HH–1K, TH–1F, TH–

1L, UH–1A, UH–1B, UH–1E, UH–1F, UH–1H, 

UH–1L, and UH–1P helicopters, and 

Southwest Florida Model SW204, SW204HP, 

SW205, and SW205A–1 helicopters, with tail 

rotor (T/R) slider, part number (P/N) 204–

010–720–3 or P/N 204010720–3, installed, 

certificated in any category. 

Compliance: Required as indicated. 

To prevent failure of the T/R slider, which 

could result in loss of T/R control and 

subsequent loss of control of the helicopter, 

accomplish the following: 

(a) Within 25 hours time-in-service (TIS), 

unless accomplished previously: 

(1) Review the helicopter records to 

determine the Commercial and Government 

Entity (CAGE) code of the T/R slider. If 

necessary, remove the installed T/R slider to 

determine the CAGE code. 

(2) If the T/R slider is an FAA approved 

part; for example, an original equipment 

manufacturer (OEM) part, and has a legible 

CAGE code other than Code 15716 or 26098; 

no further action is required. 

(3) If you cannot determine whether the T/ 

R slider is an FAA approved part and it 

contains no stamped CAGE code, an illegible 

stamped CAGE code, or is stamped with a 

CAGE code 15716 or 26098: 

(i) Before further flight, unless 

accomplished previously, and thereafter at 

intervals not to exceed 25 hours TIS, 

magnaflux inspect the T/R slider for a crack. 

(ii) If a crack is found, before further flight, 

replace the cracked T/R slider with an 

airworthy T/R slider. 

Note 1: T/R sliders manufactured by Forest 

Scientific, Inc., were produced under a 

military contract and do not meet the OEM 

specifications. The machining process 

resulted in excess surface roughness. See 

Figure 1 of this AD.

P/N on them and do not have a CAGE code 

marking on the part. 

(iii) On or before accumulating 1000 hours 

TIS or on or before 12 months, whichever 

occurs first, replace each T/R slider that has 

an illegible CAGE code or Code 15716 or 

26098 with an FAA approved airworthy 

slider without a CAGE code or with a legible 

CAGE code other than 15716 or 26098. Any 

T/R slider removed from service based on the 

requirements of this paragraph is not eligible 

for installation on any helicopter. 

(iv) Replacing the T/R slider with an FAA 

approved airworthy T/R slider without a 

CAGE code or with a legible CAGE code 

other than 15716 or 26098, constitutes 

terminating action for the requirements of 

this AD.

14 CFR Part 97 

[Docket No. 30512 ; Amendment No. 3183] 

Standard Instrument Approach 

Procedures; Miscellaneous 

Amendments 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This amendment amends 

Standard Instrument Approach 

Procedures (SIAPs) for operations at 

certain airports. These regulatory 

actions are needed because of changes 

occurring in the National Airspace 

System, such as the commissioning of 

new navigational facilities, addition of 

new obstacles, or changes in air traffic 

requirements. These changes are 

designed to provide safe and efficient 

use of the navigable airspace and to 

promote safe flight operations under 

instrument flight rules at the affected 

airports. 

DATES: This rule is effective September 

11, 2006. The compliance date for each 

SIAP is specified in the amendatory 

provisions. 

The incorporation by reference of 

certain publications listed in the 

regulations is approved by the Director 

of the Federal Register as of September 

11, 2006.

SUPPLEMENTARY INFORMATION: This 

amendment to Title 14, Code of Federal 

Regulations, part 97 (14 CFR part 97) 

amends Standard Instrument Approach 

Procedures (SIAPs). The complete 

regulatory description of each SIAP is 

contained in the appropriate FAA Form 

8260, as modified by the the National 

Flight Data Center (FDC)/Permanent 

Notice to Airmen (P–NOTAM), which is 

incorporated by reference in the 

amendment under 5 U.S.C. 552(a), 1 

CFR part 51, and § 97.20 of the Code of 

Federal Regulations. Materials 

incorporated by reference are available 

for examination or purchase as stated 

above. 

The large number of SIAPs, their 

complex nature, and the need for a 

special format make their verbatim 

publication in the Federal Register 

expensive and impractical. Further, 

airmen do not use the regulatory text of 

the SIAPs, but refer to their graphic 

depiction on charts printed by 

publishers of aeronautical materials. 

Thus, the advantages of incorporation 

by reference are realized and 

publication of the complete description 

of each SIAP contained in FAA form 

documents is unnecessary. The 

provisions of this amendment state the 

affected CFR sections, with the types 

and effective dates of the SIAPs. This 

amendment also identifies the airport, 

its location, the procedure identification 

and the amendment number. 

The Rule 

This amendment to 14 CFR part 97 is 

effective upon publication of each 

separate SIAP as amended in the 

transmittal. For safety and timeliness of 

change considerations, this amendment 

incorporates only specific changes 

contained for each SIAP as modified by 

FDC/P–NOTAMs. 

The SIAPs, as modified by FDC 

P–NOTAM, and contained in this 

amendment are based on the criteria 

contained in the U.S. Standard for 

Terminal Instrument Procedures 

(TERPS). In developing these chart 

changes to SIAPs, the TERPS criteria 

were applied to only these specific 

conditions existing at the affected 

airports. All SIAP amendments in this 

rule have been previously issued by the 

FAA in a FDC NOTAM as an emergency 

action of immediate flight safety relating 

directly to published aeronautical 

charts. The circumstances which 

created the need for all these SIAP 

amendments requires making them 

effective in less than 30 days. 

Further, the SIAPs contained in this 

amendment are based on the criteria 

contained in TERPS. Because of the 

close and immediate relationship 

between these SIAPs and safety in air 

commerce, I find that notice and public 

procedure before adopting these SIAPs 

are impracticable and contrary to the 

public interest and, where applicable, 

that good cause exists for making these 

SIAPs effective in less than 30 days.
