Airworthiness Directives; Wytwornia Sprzetu Komunikacyjnego (WSK) 
PZL-Rzeszow S.A. Franklin 6A-350-C1, -C1A, -C1L, -C1R -C2, -C2A, and 
4A-235 Series Reciprocating Engines

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule, request for comments.

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

SUMMARY: This amendment supersedes an emergency airworthiness directive 
(AD) that was sent previously to all known U.S. owners and operators of 
WSK PZL-Rzeszow S.A. Franklin 6A-350-C1, -C1A, -C1L, -C2, -C2A, and 4A-
235 series reciprocating engines. This action requires removing 
diaphragm type AC4886 fuel pump, AC part number (P/N) 5656774, PZL P/N 
26.11.1710, before further flight, and prohibits installing diaphragm 
type AC4886 fuel pump, AC P/N 5656774, PZL P/N 26.11.1710. This 
amendment is prompted by several reports of failures of the valves and 
diaphragms in certain diaphragm type AC4886 fuel pumps, AC P/N 5656774, 
PZL P/N 26.11.1710, and adds the 6A-350-C1R engine to the 
applicability. The actions specified by this AD are intended to prevent 
reduction or loss of engine power or external fuel leaks.

DATES: Effective March 21, 2003.
    Comments for inclusion in the Rules Docket must be received on or 
before May 5, 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-20-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 
the Internet using the following address: ``[email protected]''. 
Comments sent via the Internet must contain the docket number in the 
subject line.

FOR FURTHER INFORMATION CONTACT: Richard Woldan, Aerospace Engineer, 
Engine Certification Office, FAA, Engine and Propeller Directorate, 12 
New England Executive Park; Burlington, MA 01803-5299; telephone (781) 
238-7136; fax (781) 238-7199.

SUPPLEMENTARY INFORMATION: On August 27, 2002, the Federal Aviation 
Administration (FAA) issued Emergency airworthiness directive (AD) 
2002-18-51, that applies to WSK PZL-Rzeszow S.A. Franklin 6A-350-C1, -
C1A, -C1L, -C2, -C2A, and 4A-235 series reciprocating engines. That AD 
requires before further flight, removing type AC4886 fuel pump, AC P/N 
5656774, PZL P/N 26.11.1710, and prohibits installation of diaphragm 
type AC4886 fuel pump, AC P/N 5656774, PZL P/N 26.11.1710 fuel pump 
after receipt of that AD. That action was prompted by several reports 
of pump failure. This condition, if not corrected, could result in 
reduction or loss of engine power or external fuel leaks.
    Since AD 2002-18-51 was issued, the FAA has determined that the 6A-
350-C1R engine was inadvertently omitted from the applicability of that 
AD.

FAA's Determination of an Unsafe Condition and Required Actions

    Since the unsafe condition described is likely to exist or develop 
on other engines of the same type design, the FAA issued emergency AD 
2002-18-51 to prevent reduction or loss of engine power or external 
fuel leaks. This AD requires before further flight, removing diaphragm 
type AC4886 fuel pumps, AC P/N 5656774, PZL P/N 26.11.1710, and 
prohibits installation of diaphragm type AC4886 fuel pumps, AC P/N 
5656774, PZL P/N 26.11.1710, fuel pump after the effective date of this 
AD.

Immediate Adoption of This AD

    Since it was found that immediate corrective action was required, 
notice and opportunity for prior public comment thereon were 
impracticable and contrary to the public interest, and good cause 
existed to make the AD effective immediately on August 27, 2002, to all 
known U.S. owners and operators of WSK PZL-Rzeszow S.A. Franklin 6A-
350-C1, -C1A, -C1L, -C2, -C2A, and 4A-235 series reciprocating engines. 
These conditions still exist, and the AD is hereby published in the 
Federal Register as an amendment to section 39.13 of part 39 of the 
Federal Aviation Regulations (14 CFR part 39) to make it effective to 
all persons.

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 notice must submit a self-addressed, 
stamped postcard on which the following statement is made: ``Comments 
to

[[Page 10654]]

Docket Number 2002-NE-20-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.

August 2002 on this subject.
    (b) After receipt of this AD, do not install diaphragm type 
AC4886 fuel pump, AC P/N 5656774, PZL P/N 26.11.1710.

Alternative Methods of Compliance

    (c) 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, Engine Certification Office (ECO). 
Operators must submit their requests through an appropriate FAA 
Maintenance Inspector, who may add comments and then send it to the 
Manager, ECO.

    Note 2: Information concerning the existence of approved 
alternative methods of compliance with this airworthiness directive, 
if any, may be obtained from the ECO.
