Federal Register / Vol. 75, No. 50 / Tuesday, March 16, 2010 / Rules and Regulations 12441 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective April 20, 2010. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Thielert Aircraft 

Engines GmbH (TAE) models TAE 125–01 

and TAE 125–02–99 reciprocating engines 

installed in, but not limited to, Cessna 172 

and (Reims-built) F172 series (EASA STC No. 

EASA.A.S.01527); Piper PA–28 series (EASA 

STC No. EASA.A.S. 01632); APEX (Robin) 

DR 400 series (EASA STC No. A.S.01380); 

and Diamond Aircraft Industries Models 

DA40 and DA42 airplanes. 

Reason 

(d) As a consequence of occurrences and 

service experience, Thielert Aircraft Engines 

GmbH has introduced a new rail pressure 

control valve part number (P/N) 05–7320– 

E000702 and P/N 02–7320–04100R3 and has 

amended the Airworthiness Limitation 

Section (ALS) of the Operation & 

Maintenance Manual OM–02–02 to include a 

replacement of the rail pressure control 

valve. Failure of this part could result in inflight shutdowns of the engine(s). 

This AD results from mandatory 

continuing airworthiness information 

(MCAIs) issued by an aviation authority of 

another country to identify and correct an 

unsafe condition on an aviation product. We 

are issuing this AD to prevent engine in-flight 

shutdown, possibly resulting in reduced 

control of the aircraft. 

Actions and Compliance 

(e) Unless already done, do the following 

actions. 

TAE 125–02–99 Reciprocating Engines 

(1) For TAE 125–02–99 reciprocating 

engines, within 100 flight hours after the 

effective date of this AD, replace the existing 

rail pressure control valve with a rail 

pressure control valve P/N 05–7320– 

E000702, and modify the Vrail plug to make 

it compatible with the replacement rail 

pressure control valve. 

(2) Guidance on the valve replacement and 

rail modification specified in paragraph (e)(1) 

of this AD can be found in Thielert Repair 

Manual RM–02–02, Chapter 73–10.08, and 

Chapter 39–40.08, respectively. 

TAE 125–01 Reciprocating Engines 

(3) For TAE 125–01 reciprocating engines, 

within 100 flight hours after the effective 

date of this AD, replace the existing rail 

pressure control valve with a rail pressure 

control valve, P/N 02–7320–04100R3. 

(4) Guidance on the valve replacement 

specified in paragraph (e)(3) of this AD can 

be found in Thielert Repair Manual RM–02– 

01, Chapter 29.0. 

TAE 125–02–99 and TAE 125–01 Engines, 

Repetitive Replacements of Rail Pressure 

Control Valves 

(5) Thereafter, for affected TAE 125–02–99 

and TAE 125–01 engines, replace the rail 

pressure control valve with the same P/N 

valve within every 600 flight hours. 

FAA AD Differences 

(f) This AD differs from the Mandatory 

Continuing Airworthiness Information 

(MCAI) and/or service information as 

follows: 

(1) For the TAE 125–02–99 reciprocating 

engines, we reduced the initial compliance 

time from within 110 flight hours to within 

100 flight hours after the effective date of this 

AD. 

(2) For the TAE 125–01 reciprocating 

engines, we changed initial compliance time 

from within the next 3 months to within 100 

flight hours after the effective date of this AD. 

(3) The MCAIs instruct the operators to 

follow Thielert Maintenance Manual, 

Chapter 5, Airworthiness Limitations, for the 

repetitive replacement compliance time for 

the rail pressure control valve, which, in the 

manual, is 600 flight hours. We found it 

necessary to specify the repetitive 

replacement compliance time in this AD, of 

within every 600 flight hours. 

Alternative Methods of Compliance 

(AMOCs) 

(g) The Manager, Engine Certification 

Office, FAA, has the authority to approve 

AMOCs for this AD, if requested using the 

procedures found in 14 CFR 39.19.

Airworthiness Directives; MD 

Helicopters, Inc. Model MD–900 

Helicopters 

AGENCY: Federal Aviation 

Administration, DOT. 

ACTION: Final rule. 

SUMMARY: This amendment supersedes 

an existing airworthiness directive (AD) 

for MD Helicopters, Inc. (MDHI) model 

MD–900 helicopters that currently 

requires applying serial numbers to 

certain parts, increasing the life limit for 

various parts, maintaining a previously 

established life limit for a certain 

vertical stabilizer control system (VSCS) 

bellcrank assembly and bellcrank arm, 

and correcting the part number for the 

VSCS bellcrank arm. This amendment 

requires the same actions as the existing 

AD, except it reduces the life limit of 

the swashplate spherical slider bearing 

(slider bearing). It further corrects what 

was described as a ‘‘bellcrank arm’’ life 

limit in the current AD and correctly 

describes it as another ‘‘bellcrank 

assembly’’ life limit. This amendment is 

prompted by two reports of cracks in the 

slider bearing that occurred well before 

the previously increased retirement life 

of 2,030 hours time-in-service (TIS) was 

reached. The actions specified by this 

AD are intended to establish appropriate 

life limits for various parts, and to 

prevent fatigue failure of those parts and 

subsequent loss of control of the 

helicopter. 

DATES: Effective April 20, 2010.

SUPPLEMENTARY INFORMATION: A 

proposal to amend 14 CFR part 39 by 

superseding AD 99–16–13, Amendment 

39–11248 (64 FR 42824, August 6, 

1999), Docket No. 98–SW–42–AD, for 

the MDHI Model MD–900 helicopters 

was published in the Federal Register 

on October 22, 2009 (74 FR 54495). The 

action proposed to decrease the life 

limit of the slider bearing from 2,030 

hours TIS to 700 hours time-in-service 

(TIS). Additionally, changing the 

nomenclature for part number 

900F2341712–101 from bellcrank arm to 

bellcrank assembly was proposed. The 

action also proposed to retain the 

requirements of the existing AD to apply 

serial numbers to various parts, and to 

retain the life limits of various other 

parts. 

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. 

The FAA estimates that this AD will 

affect 27 helicopters of U.S. registry, and 

that it will take approximately 2.5 work 

hours per helicopter to accomplish the 

serialization of the affected parts at an 

average labor rate of $85 per work hour. 

Additionally, it is estimated that 8 of 

those aircraft will require replacement 

of the slider bearing, which will require 

approximately 7 work hours to 

accomplish at an average labor rate of 

$85 per work hour. Required parts will 

cost approximately $11,080 per 

helicopter for the slider bearing. Based 

on these figures, we estimate the total 

cost impact of the AD on U.S. operators 

to be $99,137. 

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 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.

Protection changed to U.S. Customs and 

Border Protection (CBP) and the name of 

the Bureau of Immigration and Customs 

Enforcement changed to U.S. 

Immigration and Customs Enforcement 

(ICE). This final rule revises two chapter 

headings in title 19 of the Code of 

Federal Regulations to reflect the name 

changes for those two Department of 

Homeland Security (DHS) components.

SUPPLEMENTARY INFORMATION: 

Background 

On November 25, 2002, the President 

signed the Homeland Security Act of 

2002, 6 U.S.C. 101 et seq., Public Law 

107–296, (the ‘‘HSA’’), establishing the 

Department of Homeland Security 

(DHS). Pursuant to section 403(1) of the 

HSA (6 U.S.C. 203(1)), the U.S. Customs 

Service was transferred from the 

Department of the Treasury to DHS 

effective March 1, 2003. In addition, the 

Customs Service was renamed as the 

‘‘Bureau of Customs and Border 

Protection’’ pursuant to section 1502 of 

the HSA. Section 442 of the HSA (6 

U.S.C. 252) established the ‘‘Bureau of 

Border Security.’’ Under section 1502 of 

the HSA, the Bureau of Border Security 

was renamed as the ‘‘Bureau of 

Immigration and Customs Enforcement,’’ 

effective March 1, 2003. The President’s 

‘‘Reorganization Plan Modification for 

the Department of Homeland Security,’’ 

dated January 30, 2003, memorializes 

these name changes. 

On January 18, 2007, DHS notified 

Congress that it was changing the name 

of the Bureau of Customs and Border 

Protection to ‘‘U.S. Customs and Border 

Protection (CBP)’’ and the name of the 

Bureau of Immigration and Customs 

Enforcement to ‘‘U.S. Immigration and 

Customs Enforcement (ICE).’’ Pursuant 

to section 872(a)(2) of the HSA (6 U.S.C. 

452(a)(2), notice of the name change was 

provided to Congress no later than 60 

days before the change could become 

effective. On April 23, 2007, a notice 

was published in the Federal Register to 

inform the public that DHS had changed 

the names of the two components 

effective March 31, 2007. 72 FR 20131. 

This document revises the headings of 

chapters I and IV of title 19 of the Code 

of Federal Regulations (19 CFR) to 

reflect the agency name changes as set 

forth in the Federal Register notice of 

April 23, 2007. 

Inapplicability of Prior Public Notice 

and Delayed Effective Date 

Requirements 

This regulation involves matters 

relating to agency management and 

involves a technical change regarding 

the name of the two DHS components. 

For this reason, pursuant to 5 U.S.C. 

553(a)(2), prior notice and comment is 

not required. Because this is not a 

substantive rule, publication and service 

of the rule thirty days before its effective 

date, pursuant to 5 U.S.C. 553(d), is 

likewise not required. 

The Regulatory Flexibility Act and 

Executive Order 12866 

Because no notice of proposed 

rulemaking is required, the provisions 

of the Regulatory Flexibility Act (5 

U.S.C. 601 et seq.) do not apply. 

Further, this amendment does not meet 

the criteria for a ‘‘significant regulatory 

action’’ for purposes of Executive Order 

12866. 

Amendments to the Regulations 

■ For the reasons set forth above in the 

preamble, under the authority of 6 

U.S.C. 452, and the April 23, 2007, DHS 

Federal Register notice announcing the 

name change for CBP and ICE, the 

headings of chapters I and IV of title 19 

of the Code of Federal Regulations are 

amended as set forth below: 

■ 1. Revise the chapter I heading to title 

19 to read as follows. 

Chapter I—U.S. Customs and Border 

Protection, Department of Homeland 

Security; Department of the Treasury 

■ 2. Revise the chapter IV heading to
