SUPPLEMENTARY INFORMATION: On June 6, 2006, the FAA issued AD 2006–12–19, Amendment 39–14645 (71 FR 34003, June 13, 2006). That AD requires replacing certain actuator yokes with improved actuator yokes on Hamilton Sundstrand model 14RF–19 propellers. That AD resulted from certain propeller system actuator yoke arms breaking during flight. That condition, if not corrected, could result in actuator yoke arms breaking during flight, which could cause high propeller vibration and contribute to reduced controllability of the airplane. Actions Since AD 2006–12–19 Was Issued Since that AD was issued, we discovered a P/N error in applicability VerDate Aug<31>2005 14:56 Jul 28, 2006 Jkt 208001 paragraph (c). Actuator assemblies P/N 790119–6 should be P/N 790199–6. AD 2006–12–19 technically cannot be complied with having an incorrect P/N. This AD supersedure corrects that P/N. Relevant Service Information We have reviewed and approved the technical contents of Hamilton Sundstrand Service Bulletin 14RF–19– 61–113, Revision 1, dated September 2, 2003, that describes procedures for installing a new propeller system actuator yoke arm, P/N 810436–3. FAA’s Determination and Requirements of This AD The unsafe condition described previously is likely to exist or develop on other Hamilton Sundstrand model 14RF–19 propellers of the same type design. We are issuing this AD to prevent actuator yoke arms breaking during flight, which could cause high propeller vibration and contribute to reduced controllability of the airplane. This AD requires replacing the actuator yoke arm, P/N 810436–2, on model 14RF–19 propellers with an improved actuator yoke arm, P/N 810436–3. You must use the service information described previously to perform the actions required by this AD. FAA’s Determination of the Effective Date Since an unsafe condition exists that requires the immediate adoption of this AD, we have found that notice and opportunity for public comment before issuing this AD are impracticable, and that good cause exists for making this amendment effective in less than 30 days. Comments Invited This AD is a final rule that involves requirements affecting flight safety and was not preceded by notice and an opportunity for public comment; however, we invite you to send us any written relevant data, views, or arguments regarding this AD. Send your comments to an address listed under ADDRESSES. Include ‘‘AD Docket No. FAA–2005–21691; Directorate Identifier 2005–NE–13–AD’’ in the subject line of your comments.

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD) for Hamilton Sundstrand model 14RF-19 propellers. That AD 
currently requires replacing certain actuator yokes with improved 
actuator yokes. This AD requires the same actions. This AD results from 
the discovery of a part number (P/N) error in the applicability 
paragraph of AD 2006-12-19. We are

[[Page 43042]]

issuing this AD to prevent actuator yoke arms breaking during flight, 
which could cause high propeller vibration and contribute to reduced 
controllability of the airplane.

DATES: Effective August 30, 2006. The Director of the Federal Register 
previously approved the incorporation by reference of certain 
publications listed in the regulations as of July 18, 2006 (71 FR 
34003; June 13, 2006).

SUPPLEMENTARY INFORMATION: On June 6, 2006, the FAA issued AD 2006-12-
19, Amendment 39-14645 (71 FR 34003, June 13, 2006). That AD requires 
replacing certain actuator yokes with improved actuator yokes on 
Hamilton Sundstrand model 14RF-19 propellers. That AD resulted from 
certain propeller system actuator yoke arms breaking during flight. 
That condition, if not corrected, could result in actuator yoke arms 
breaking during flight, which could cause high propeller vibration and 
contribute to reduced controllability of the airplane.

Actions Since AD 2006-12-19 Was Issued

    Since that AD was issued, we discovered a P/N error in 
applicability paragraph (c). Actuator assemblies P/N 790119-6 should be 
P/N 790199-6. AD 2006-12-19 technically cannot be complied with having 
an incorrect P/N. This AD supersedure corrects that P/N.

Relevant Service Information

    We have reviewed and approved the technical contents of Hamilton 
Sundstrand Service Bulletin 14RF-19-61-113, Revision 1, dated September 
2, 2003, that describes procedures for installing a new propeller 
system actuator yoke arm, P/N 810436-3.

FAA's Determination and Requirements of This AD

    The unsafe condition described previously is likely to exist or 
develop on other Hamilton Sundstrand model 14RF-19 propellers of the 
same type design. We are issuing this AD to prevent actuator yoke arms 
breaking during flight, which could cause high propeller vibration and 
contribute to reduced controllability of the airplane. This AD requires 
replacing the actuator yoke arm, P/N 810436-2, on model 14RF-19 
propellers with an improved actuator yoke arm, P/N 810436-3. You must 
use the service information described previously to perform the actions 
required by this AD.

FAA's Determination of the Effective Date

    Since an unsafe condition exists that requires the immediate 
adoption of this AD, we have found that notice and opportunity for 
public comment before issuing this AD are impracticable, and that good 
cause exists for making this amendment effective in less than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety and was not preceded by notice and an opportunity for public 
comment; however, we invite you to send us any written relevant data, 
views, or arguments regarding this AD. Send your comments to an address 
listed under ADDRESSES. Include ``AD Docket No. FAA-2005-21691; 
Directorate Identifier 2005-NE-13-AD'' in the subject line of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of the rule that might 
suggest a need to modify it.
    We will post all comments we receive, without change, to https://
dms.dot.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 the DMS Web 
site, anyone can find and read the comments in any of our dockets, 
including the name of the individual who sent the comment (or signed 
the comment on behalf of an association, business, labor union, etc.).

Examining the AD Docket

    You may examine the docket that contains the AD, any comments 
received, and any final disposition in person at the Docket Management 
Facility Docket Office between 9 a.m. and 5 p.m., Monday through 
Friday, except Federal holidays. The Docket Office (telephone (800) 
647-5227) is located on the plaza level of the Department of 
Transportation Nassif Building at the street address stated in 
ADDRESSES. Comments will be available in the AD docket shortly after 
the DMS receives them.

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.

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;

[[Page 43043]]

    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 a summary of the costs to comply with this AD and 
placed it in the AD Docket. You may get a copy of this summary by 
sending a request to us at the address listed under ADDRESSES.

34003, June 13, 2006), and by adding a new airworthiness directive, 
Amendment 39-14701, to read as follows:

2006-16-01 Hamilton Sundstrand: Amendment 39-14701. Docket No. FAA-
2005-21691; Directorate Identifier 2005-NE-13-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective August 
15, 2006.

Affected ADs

    (b) This AD supersedes AD 2006-12-19.

Applicability

    (c) This AD applies to Hamilton Sundstrand Model 14RF-19 
propellers with propeller system actuator yoke arms, part number (P/
N) 810436-2, which might be installed in actuator assemblies P/N 
790199-6. These propellers are installed on, but not limited to, 
SAAB 340 airplanes.

Unsafe Condition

    (d) This AD results from the discovery of a part number (P/N) 
error in the applicability paragraph of AD 2006-12-19. We are 
issuing this AD to prevent actuator yoke arms breaking during 
flight, which could cause high propeller vibration and contribute to 
reduced controllability of the airplane.

AD performed within 60 days after the effective date of this AD, 
unless the actions have already been done.

Service Bulletin 14RF-19-61-113, Revision 1, dated September 2, 
2003, replace all actuator yoke arms, P/N 810436-2, with improved 
actuator yoke arms, P/N 810436-3.
    (g) Mark newly installed actuators using the Accomplishment 
Instructions of Hamilton Sundstrand Service Bulletin 14RF-19-61-113, 
Revision 1, dated September 2, 2003.
    (h) After the effective date of this AD, do not install any 
actuator yoke arms, P/N 810436-2, into any propeller assembly.

Alternative Methods of Compliance

    (i) The Manager, Boston Aircraft Certification Office, has the 
authority to approve alternative methods of compliance for this AD
