ACTION: Final rule; request for 

comments. 

SUMMARY: This amendment adopts a 

new airworthiness directive (AD) for the 

Aeronautical Accessories, Inc. (AAI) 

Low Skid Landing Gear Forward 

Crosstube (Crosstube) on certain Bell 

and Agusta model helicopters. This 

action requires replacing certain AAI 

serial-numbered crosstubes installed on 

these model helicopters. This 

amendment is prompted by the 

discovery of a defect in the raw material 

used in manufacturing certain

SUPPLEMENTARY INFORMATION: This 

amendment adopts a new AD for the 

Bell Model 205A, 205A–1, 205B, 212, 

412, 412EP, and 412CF and Agusta 

Model AB412, AB412EP helicopters. 

This action requires replacing certain 

AAI serial-numbered crosstubes 

installed on these model helicopters. 

This amendment is prompted by AAI’s 

discovery of a defect in a batch of raw 

material used in the manufacture of 

these crosstubes. Preliminary tests 

indicate that surface cracking on the 

inner wall of the tubing was introduced 

during the manufacturing process. 

There have been no failures reported in 

the field. The defect was discovered 

during the forming operation at AAI. 

This condition, if not corrected, could 

result in failure of a crosstube and 

subsequent collapse of the landing gear. 

We have reviewed AAI Alert Service 

Bulletin No. AA–10012, dated March 5, 

2010 (ASB), which describes a possible 

defect in the material used to 

manufacture the crosstube, part number 

(P/N) 212–320–103, which is also 

included as part of AAI Low Skid Gear 

Assembly Kits, P/N 412–320–500 and 

412–320–502. The ASB specifies 

locating the serial number (S/N) of each 

crosstube, and replacing, within 25 

hours time-in-service (TIS), each 

crosstube within the S/N range of AA– 

574 through AA–628, by following the 

replacement procedures contained in 

the Instructions for Continued 

Airworthiness AA–01136. 

This unsafe condition is likely to exist 

or develop on other helicopters of these 

same type designs with an affected 

crosstube. Therefore, this AD is being 

issued to prevent failure of a crosstube 

and subsequent collapse of the landing 

gear. This AD requires, within 25 hours 

TIS, replacing any affected crosstube 

with an airworthy crosstube. 

The short compliance time involved 

is required because the previously 

described critical unsafe condition can 

adversely affect the structural integrity 

of the helicopter. Therefore, replacing 

any affected crosstube with an 

airworthy crosstube is required within 

25 hours TIS, and this AD must be 

issued immediately. 

Since a situation exists that requires 

the immediate adoption of this 

regulation, it is found that notice and 

opportunity for prior public comment 

hereon are impracticable, and that good 

cause exists for making this amendment 

effective in less than 30 days. 

We estimate that this AD will affect 

19 helicopters, and replacing each 

affected crosstube will take about 5 

work hours at an average labor rate of 

$85 per work hour. Required parts will 

cost about $4,925 per helicopter. Based 

on these figures, we estimate the total 

cost impact of the AD on U.S. operators 

to be $101,650. 

Comments Invited 

This AD is a final rule that involves 

requirements that affect flight safety and 

was not preceded by notice and an 

opportunity for public comment; 

however, we invite you to submit any 

written data, views, or arguments 

regarding this AD. Send your comments 

to an address listed under ADDRESSES. 

Include ‘‘Docket No. FAA–2010–0487; 

Directorate Identifier 2010–SW–032– 

AD’’ at the beginning of your comments. 

We specifically invite comments on the 

WReier-Aviles on DSKGBLS3C1PROD with RULES

28752 Federal Register / Vol. 75, No. 99 / Monday, May 24, 2010 / Rules and Regulations 

overall regulatory, economic, 

environmental, and energy aspects of 

the AD. We will consider all comments 

received by the closing date and may 

amend the AD in light of those 

comments. 

We will post all comments we 

receive, without change, to http:// 

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact with FAA 

personnel concerning this AD. Using the 

search function of our docket Web site, 

you can find and read the comments to 

any of our dockets, including the name 

of the individual who sent the 

comment. You may review the DOT’s 

complete Privacy Act Statement in the 

Federal Register published on April 11, 

2000 (65 FR 19477–78). 

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 11032, 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 AD docket 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.

Amendment and Establishment of 

Restricted Areas and Other Special 

Use Airspace, Avon Park Air Force 

Range, FL 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This action restructures the 

special use airspace (SUA) at the Avon 

Park Air Force Range (APAFR), Florida. 

The changes provide additional 

restricted airspace needed for training in 

high altitude weapons releases and 

other hazardous activities, and 

reconfigure the military operations areas 

(MOA) to contain nonhazardous flight 

operations. These changes will permit 

realistic training in current tactics to be 

conducted at the Range and enable more 

efficient use of the National Airspace 

System. 

DATES: Effective date 0901 UTC, July 29, 

2010.

SUPPLEMENTARY INFORMATION: 

Background 

On Thursday, February 12, 2009, the 

FAA published in the Federal Register 

a notice of proposed rulemaking 

(NPRM) to restructure the SUA at the 

APAFR, Florida (74 FR 7018). Interested 

parties were invited to participate in 

this rulemaking proceeding by 

submitting written comments on the 

proposal to the FAA. Four responses 

were received. 

Discussion of Comments
