Airworthiness Directives; Teledyne Continental Motors E-165, E-
185, E-225, O-470 and IO-470 Series Reciprocating Engines
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD) that
is applicable to Teledyne Continental Motors E-165, E-185, E-225, O-470
and IO-470 series reciprocating engines. This action supersedes
priority letter AD 97-15-01 that currently requires removal from
service of affected cylinders, and reassembly with serviceable parts.
This action adds the latest revision to applicable Critical Service
Bulletin (CSB), corrects references to Parts of that CSB, and lists a
new contact telephone number to obtain the CSB from the manufacturer.
This amendment is prompted by the availability of the new CSB revision
and the need to correct the CSB references. The actions specified by
this AD are intended to prevent extreme side loading of the piston, and
consequent failure of the piston and engine.
DATES: Effective October 27, 1997.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of October 27, 1997.
Comments for inclusion in the Rules Docket must be received on or
before December 9, 1997.
ADDRESSES: Submit comments in triplicate to the Federal Aviation
Administration (FAA), New England Region, Office of the Assistant Chief

SUPPLEMENTARY INFORMATION: On July 17, 1997, the Federal Aviation
Administration (FAA) issued priority letter airworthiness directive
(AD) 97-15-01, applicable to Teledyne Continental Motors (TCM) new and
rebuilt Model O-470 and IO-470 series engines with serial numbers (S/
Ns) listed in Table 1 of TCM Critical Service Bulletin (CSB) No. CSB97-
10, dated June 19, 1997; and TCM Model E-165, E-185, E-225, O-470 and
IO-470 series engines, regardless of S/N, which have cylinder(s) with
part number and purchase date as shown in Table 2 of TCM CSB No. CSB97-
10, dated June 19, 1997. The priority letter AD requires removal from
service of affected cylinders, and reassembly with serviceable parts.
That action was prompted by a report from TCM of an engine equipped
with factory new cylinders with approximately 28 hours time in service
(TIS) that was discovered to have high aluminum particulates during an
oil analysis. Further investigation revealed the piston pin plug was
experiencing increased wear, which was, in turn, traced to the
roughness of the cylinder bore. A stock sweep at the factory revealed
10 additional cylinders with this condition. The cylinder bore surface
finish on some cylinders is rougher than specified. This condition was
caused during a manganese phosphate coating process on the cylinder
barrel bore. The cylinders are exposed to the phosphate process in
batches of 10 cylinders. The manganese phosphate coating provides
resistance to corrosion during the first hours of operation. The
problem occurred because of extended exposure of the cylinder bore to
the manganese phosphate treatment which results in the surface finish
being rougher than specified, although the piston pin plug will wear
first; it will, in turn, wear a groove in the cylinder wall which will
cause massive oil consumption in the near future. This will result in
accelerated piston pin plug wear, as the piston pin plug is made of
aluminum while the cylinder barrel is made of nitrided steel. The FAA
has determined that one side of the piston pin could disconnect from
the piston if the wear of the pin plug becomes excessive. This
condition, if not corrected, can result in extreme side loading of the
piston, and consequent failure of the piston and engine.
Since issuance of the priority letter AD, the FAA has determined
that the references to Parts 2A and 2B, and Appendix A of the CSB are
in error, and should reference Parts 2-1(a) and 2-2. In addition, this
superseding AD lists a new, toll-free contact telephone number to
obtain the CSB from the manufacturer.
Also, the FAA has reviewed and approved the technical contents of
the latest revision, TCM CSB No. CSB97-10A, dated July 15, 1997, that
provides a list of S/Ns of new and rebuilt model O-470 and IO-470
engines with affected cylinders installed, and a list of cylinders with
part number and purchase date that may be installed on E-165, E-185, E-
225, O-470 and IO-470 series engines, regardless of serial number. This
CSB describes procedures for removal and shipment to the factory of
affected cylinders, and procedures for reassembly with serviceable
parts.
Since an unsafe condition has been identified that is likely to
exist or develop on other engines of this same type design, this AD
supersedes priority letter AD 97-15-01 to add reference to the latest
revision of the applicable CSB, correct incorrect references to parts
of the applicable CSB, and list a new contact telephone number to
obtain the CSB from the manufacturer. Operators that have removed
affected cylinders in accordance with priority letter AD 97-15-01 or
the original version of the CSB are in compliance with this AD and no
further action is required. The actions are required to be accomplished
in accordance with the CSB described previously.
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.
[[Page 52943]]
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 Docket Number 97-ANE-39-AD.'' The postcard will be date stamped and
returned to the commenter.
The regulations adopted herein will not have substantial direct
effects 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. Therefore, in
accordance with Executive Order 12612, it is determined that this final
rule does not have sufficient federalism implications to warrant the
preparation of a Federalism Assessment.
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.
