Airworthiness Directives; Hartzell Propeller Inc. Model ( )HC-( 
)2Y( )-( ) propellers

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD) that 
is applicable to Hartzell Propeller Inc. model ( )HC-( )2Y( )-( ) 
propellers, with certain serial numbers (SN's) of two-bladed aluminum 
propeller hubs part numbers (P/N's) D-6522-1, D-6522-2, D-6529-1, and 
D-6559-3 installed. This action requires removal from service of those 
certain SN's of two-bladed aluminum propeller hubs and replacement with 
serviceable hubs. This amendment is prompted by a two-bladed aluminum 
propeller hub manufacturing quality control problem. The actions 
specified in this AD are intended to prevent in-flight propeller blade 
separation resulting in airframe and engine damage, and possible loss 
of the airplane.

DATES: Effective January 23, 2003. The incorporation by reference of 
certain publications listed in the rule is approved by the Director of 
the Federal Register as of January 23, 2003.
    Comments for inclusion in the Rules Docket must be received on or 
before March 10, 2003.

ADDRESSES: Submit comments in triplicate to the Federal Aviation 
Administration (FAA), New England Region, Office of the Regional 
Counsel, Attention: Rules Docket No. 2002-NE-25-AD, 12 New England 
Executive Park, Burlington, MA 01803-5299. Comments may be inspected at 
this location, by appointment, between 8 a.m. and 4:30 p.m., Monday 
through Friday, except Federal holidays. Comments may also be sent via

New England Region, Office of the Regional Counsel, 12 New England 
Executive Park, Burlington, MA; or at the Office of the Federal 
Register, 800 North Capitol Street, NW., suite 700, Washington, DC.

FOR FURTHER INFORMATION CONTACT: Tomaso DiPaolo, Aerospace Engineer, 
Chicago Aircraft Certification Office, FAA, Small Airplane Directorate, 
2300 East Devon Avenue, Des Plaines, IL 60018; telephone (847) 294-
7031; fax (847) 294-7834.

SUPPLEMENTARY INFORMATION: On August 19, 2002, the FAA was notified by 
Hartzell Propeller Inc. that certain two-bladed aluminum propeller hub 
SN's installed in 2-bladed propellers were found to have subsurface 
discontinuities in the aluminum. Some of these hubs have been installed 
in propellers and some have been shipped as spares. The discontinuities 
were not removed during the propeller hub forging process, and could 
initiate fatigue cracking in the propeller hub arms. This final rule; 
request for comments, replaces affected hubs determined to be under 
higher stresses based on specific airplane installation, within 50 
hours time-since-new (TSN) or 12 months from the effective date of the 
AD, whichever occurs first, and affected hubs determined to be under 
lower stresses based on specific airplane installation, within 100 
hours TSN or 12 months from the effective date of this AD, whichever 
occurs first. This condition, if not corrected, could result in in-
flight propeller blade separation, airframe and engine damage, and 
possible loss of the airplane.

Manufacturer's Service Information

    The FAA has reviewed and approved the technical contents of 
Hartzell Propeller Inc. Alert Service Bulletin

[[Page 1002]]

(ASB) HC-ASB-61-259, dated September 4, 2002, that provides a SN list 
of 123 affected propeller hubs and describes procedures for hub 
replacement. This AD action has denoted the remaining 52 serial 
numbered propeller hubs that need to be replaced.

FAA's Determination of an Unsafe Condition and Required Actions

    Since an unsafe condition has been identified that is likely to 
exist or develop on other propeller hubs of the same type design, this 
AD is being issued to prevent in-flight propeller blade separation 
resulting in airframe and engine damage, and possible loss of airplane 
control. This AD requires removal from service of certain two-bladed 
aluminum propeller hubs identified by SN and replacement with 
serviceable two-bladed aluminum propeller hubs. This action lists the 
remaining 52 serial numbered propeller hubs that need to be replaced. 
The actions are required to be done in accordance with the alert 
service bulletin described previously.

Immediate Adoption of This AD

    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.

Comments Invited

    Although this action is in the form of a final rule that involves 
requirements affecting flight safety and, thus, was not preceded by 
notice and an opportunity for public comment, comments are invited on 
this rule. Interested persons are invited to comment on this rule by 
submitting such written data, views, or arguments as they may desire. 
Communications should identify the Rules Docket number and be submitted 
in triplicate to the address specified under the caption ADDRESSES. All 
communications received on or before the closing date for comments will 
be considered, and this rule may be amended in light of the comments 
received. Factual information that supports the commenter's ideas and 
suggestions is extremely helpful in evaluating the effectiveness of the 
AD action and determining whether additional rulemaking action would be 
needed.
    Comments are specifically invited on the overall regulatory, 
economic, environmental, and energy aspects of the rule that might 
suggest a need to modify the rule. All comments submitted will be 
available, both before and after the closing date for comments, in the 
Rules Docket for examination by interested persons. A report that 
summarizes each FAA-public contact concerned with the substance of this 
AD will be filed in the Rules Docket.
    Commenters wishing the FAA to acknowledge receipt of their comments 
submitted in response to this action must submit a self-addressed, 
stamped postcard on which the following statement is made: ``Comments 
to Docket Number 2002-NE-25-AD.'' The postcard will be date stamped and 
returned to the commenter.

Regulatory Analysis

    This final rule does not have federalism implications, as defined 
in Executive Order 13132, because it would 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. Accordingly, 
the FAA has not consulted with state authorities prior to publication 
of this final rule.
    The FAA has determined that this regulation is an emergency 
regulation that must be issued immediately to correct an unsafe 
condition in aircraft, and is not a ``significant regulatory action'' 
under Executive Order 12866. It has been determined further that this 
action involves an emergency regulation under DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979). If it is determined 
that this emergency regulation otherwise would be significant under DOT 
Regulatory Policies and Procedures, a final regulatory evaluation will 
be prepared and placed in the Rules Docket. A copy of it, if filed, may 
be obtained from the Rules Docket at the location provided under the 
caption ADDRESSES.

trainers, any airplanes routinely exposed to acrobatics usage, and 
airplanes used for agricultural purposes, remove affected hubs 
listed by SN in Table 1 of this AD within 50 hours time-since-new 
(TSN) or 12 months from the effective date of this AD, whichever 
occurs first, and replace with serviceable hubs, in accordance with 
paragraphs 3.A. through 3.B.(3) of ASB HC-ASB-61-259, dated 
September 4, 2002.
    (b) For airplanes other than those listed in paragraph (a) of 
this AD, remove affected hubs listed by SN in Table 1 of this AD 
within 100 hours TSN or 12 months from the effective date of this 
AD, whichever occurs first, and replace with serviceable hubs, in 
accordance with paragraphs 3.A. through 3.B.(3) of ASB HC-ASB-61-
259, dated September 4, 2002.
    (c) After the effective date of this AD, do not install any 
propeller assembly that has a hub with a P/N D-6522-1, D-6522-2, D-
6529-1, or D-6559-3, with a SN listed in Table 1 of this AD.

Alternative Methods of Compliance

    (d) An alternative method of compliance or adjustment of the 
compliance time that provides an acceptable level of safety may be 
used if approved by the Manager, Chicago Aircraft Certification 
Office (ACO). Operators must submit their requests through an 
appropriate FAA Principal Maintenance Inspector, who may add 
comments and then send it to the Manager, Chicago ACO.

    Note 3: Information concerning the existence of approved
