ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
Hartzell Propeller Inc. models HC-B3TN-2, HC-B3TN-3, HC-B3TN-5, HC-
B3MN-3, HC-B4TN-3, HC-B4TN-5, HC-B4MN-5, HC-B4MP-3, HC-B4MP-5, and HC-
B5MP-3 propellers, installed with propeller mounting bolts, part number 
(P/N) B-3339. This AD requires initial and repetitive visual 
inspections and torque checks of certain manufacture lot numbers of 
propeller mounting bolts, P/N B-3339, and eventual removal from service 
of those bolts. This AD results from the discovery during routine

[[Page 40657]]

propeller installation that a bolt from a certain manufacture lot did 
not properly absorb the installation torque. This AD also results from 
the discovery that other bolts of the same part number from a different 
manufacture lot had material surface pitting. We are issuing this AD to 
prevent propeller attaching bolt failures or improperly secured 
propellers, which could lead to separation of the propeller from the 
airplane.

DATES: This AD becomes effective July 29, 2005. The Director of the 
Federal Register approved the incorporation by reference of certain 
publications listed in the regulations as of July 29, 2005.
    We must receive any comments on this AD by September 12, 2005.

SUPPLEMENTARY INFORMATION: Hartzell Propeller Inc. has informed us that 
recently during routine installation of a steel hub propeller, one of 
the propeller mounting bolts, P/N B-3339, did not properly absorb the 
installation torque. The suspect bolt was removed and examined. 
Hartzell Propeller Inc., found that the bolt does not have the proper 
material hardness as specified by the propeller type design 
requirements. That bolt was identified as part of LFC Manufacturing Lot 
No. 56. Hartzell Propeller Inc., examined their inventory of bolts and 
found two other Lot No. 56 bolts also below proper material hardness. 
During this investigation, Hartzell Propeller Inc. also discovered a 
quantity of bolts, P/N B-3339, from LFC Manufacturing Lot No. 12, with 
material surface pitting underneath the anti-corrosion coating. These 
pitted bolts also do not meet the propeller type design requirements. 
This condition, if not corrected, could result in propeller mounting 
bolt failures or improperly secured propellers, which could lead to 
separation of the propeller from the airplane.

Relevant Service Information

    We have reviewed and approved the technical contents of Hartzell 
Propeller Inc. Alert Service Bulletin (ASB) No. HC-ASB-61-279, Revision 
2, dated May 6, 2005, that describes procedures to visually inspect, 
torque check, and replace the affected bolts.

FAA's Determination and Requirements of This AD

    The unsafe condition described previously is likely to exist or 
develop on other Hartzell Propeller Inc. models HC-B3TN-2, HC-B3TN-3, 
HC-B3TN-5, HC-B3MN-3, HC-B4TN-3, HC-B4TN-5, HC-B4MN-5, HC-B4MP-3, HC-
B4MP-5, and HC-B5MP-3 propellers of the same type design, installed 
with propeller mounting bolts, P/N B-3339. For that reason, we are 
issuing this AD to prevent propeller mounting bolt failures or 
improperly secured propellers, which could lead to separation of the 
propeller from the airplane. This AD requires:
    <bullet> Initial visual inspection and torque check of all eight 
mounting flange bolts when P/N B-3339 bolts from LFC manufacturing Lot 
No. 12 or Lot No. 56 are present, within 50 hours time-in-service (TIS) 
or 12 months after the effective date of the AD, whichever occurs 
first; and
    <bullet> Thereafter, for all airplanes except Aerospatiale (Nord) 
Model 262(A) airplanes modified by STC SA2369SW, repetitive torque 
checks on all eight mounting flange bolts when P/N B-3339 bolts from 
LFC Manufacturing Lot No. 12 or Lot No. 56 are present, within 120 
hours TIS since-last-inspection; and
    <bullet> Thereafter, for Aerospatiale (Nord) Model 262(A) airplanes 
modified by STC SA2369SW, repetitive torque checks on all eight 
mounting flange bolts when P/N B-3339 bolts from LFC Manufacturing Lot 
No. 12 or Lot No. 56 are present, within 100 hours TIS since-last-
inspection; and
    <bullet> If any bolt fails the torque check, replacement of all 
eight bolts with P/N B-3339 bolts that are not from LFC Manufacturing 
Lot No. 12 or Lot No. 56, or with FAA-approved equivalent part number 
bolts.
    <bullet> As mandatory terminating action to the repetitive visual 
inspections and torque checks required by this AD, replacement of all 
P/N B-3339, LFC Manufacturing Lot No. 12 and Lot No. 56 bolts with P/N 
B-3339 bolts that are not from LFC Manufacturing Lot No. 12 or Lot No. 
56, or with FAA-approved equivalent part number bolts, within 12 months 
after the effective date of this AD.
    You must use the service information described previously to 
perform the visual inspections, torque checks, and bolt replacements 
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.

    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-2005-21735; 
Directorate Identifier 2005-NE-22-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 http://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 Docket 
Management System (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.). You may review the DOT's complete Privacy

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;
    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 at the 
address listed under ADDRESSES.

Unsafe Condition

    (d) This AD results from the discovery during routine propeller 
installation that a bolt from a certain manufacture lot did not 
properly absorb the installation torque. This AD also results from 
the discovery that other bolts of the same part number from a 
different certain manufacture lot had material surface pitting. We 
are issuing this AD to prevent propeller mounting bolt failures or 
improperly secured propellers, which could lead to separation of the 
propeller from the airplane.
