[Docket No. 95-ANE-18; Amendment 39-9282; AD 95-08-10]
Airworthiness Directives; Teledyne Continental Motors (TCM) Model
TSIO-360 and LTSIO-360 Engines
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule, request for comments.
-----------------------------------------------------------------------
SUMMARY: This document publishes in the Federal Register Airworthiness
Directive (AD) 95-08-10 that was sent previously to all known U.S.
owners and operators of Teledyne Continental Motors (TCM) Model TSIO-
360 E, EB, F, FB, G, GB, KB, LB, MB, and Model LTSIO-360 E, EB, and KB
reciprocating engines by individual letters. This AD requires
replacement of the suspect turbocharger check valves prior to further
flight, and prohibits special flight permits. This amendment is
prompted by three reported engine failures caused by incorrectly
assembled turbocharger oil outlet check valves, resulting in an
improperly expanded rivet that held the check valve flapper assembly
together as one unit. The actions specified by this AD are intended to
prevent complete engine failure due to an incorrectly assembled
turbocharger oil outlet check valve.
DATES: Effective July 10, 1995, to all persons except those persons to
whom it was made immediately effective by [[Page 32582]] priority
letter AD 95-08-10, issued on April 6, 1995, which contained the
requirements of this amendment.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of July 10, 1995.
Comments for inclusion in the Rules Docket must be received on or
before August 22, 1995.
ADDRESSES: Submit comments in triplicate to the Federal Aviation
Administration (FAA), New England Region, Office of the Assistant Chief
Counsel, Attention: Rules Docket No. 95-ANE-18, 12 New England

SUPPLEMENTARY INFORMATION: On April 6, 1995, the Federal Aviation
Administration (FAA) issued priority letter airworthiness directive
(AD) 95-08-10, applicable to Teledyne Continental Motors (TCM) Model
TSIO-360 E, EB, F, FB, G, GB, KB, LB, MB, and Model LTSIO-360 E, EB,
and KB reciprocating engines, which requires removal of suspect
turbocharger oil outlet check valves. That action was prompted by three
reported cases of check valve failures, two of which resulted in
complete loss of engine power. The three reported failures were caused
by incorrectly assembled turbocharger oil outlet check valves,
resulting in an improperly expanded rivet which held the check valve
flapper assembly together as one unit. The improperly expanded rivet
allowed the rivet, washer, retainer, and seal components to separate
and shift within the check valve unit.
One reported case showed that a part of the flapper assembly
blocked the oil flow to the scavenge pump, and resulted in engine
failure. Another reported case showed that the scavenge pump was
disabled when one part of the flapper assembly shifted through the
unit, again resulting in engine failure. These failures occurred early
in the life of the check valve, ranging from one hour to 40 hours total
time since new.
The incorrectly assembled check valves were manufactured between
August 1, 1994, through March 20, 1995. Accordingly, all have date code
ink stamps of either A3Q94, A4Q94, or A1Q95, indicating they were
manufactured either during the third quarter of 1994, the fourth
quarter of 1994, or the first quarter of 1995. Since an incorrectly
assembled check valve can not be visually identified by other than by
this date code, this AD must consider all check valves with these date
codes as suspect, and require their removal prior to further flight.
This condition, if not corrected, could result in damage to the oil
scavenge pump, internal engine damage and subsequent loss of complete
engine power.
The FAA has reviewed and approved the technical contents of
Teledyne Continental Motors (TCM) Critical Service Bulletin (CSB) 95-
1A, Revision A, dated April 5, 1995, that describes inspection and
replacement of suspect oil outlet check valves.
Since the unsafe condition described is likely to exist or develop
on other engines of the same type design, the FAA issued priority
letter AD 95-08-10 to prevent damage to the oil scavenge pump, internal
engine damage and subsequent loss of complete engine power. The AD
requires removal prior to further flight, of suspect turbocharger oil
outlet check valves. The actions are required to be accomplished in
accordance with the service bulletin described previously.
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 by individual letters
issued on April 6, 1995, to all known U.S. owners and operators of
Teledyne Continental Motors (TCM) Model TSIO-360 E, EB, F, FB, G, GB,
KB, LB, MB, and Model LTSIO-360 E, EB, and KB 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 Docket Number 95-ANE-18.'' 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 [[Page 32583]] of
it, if filed, may be obtained from the Rules Docket at the location
provided under the caption ADDRESSES.

Note: This AD applies to each engine identified in the preceding
applicability provision, regardless of whether it has been modified,
altered, or repaired in the area subject to the requirements of this
AD. For engines that have been modified, altered, or repaired so
that the performance of the requirements of this AD is affected, the
owner/operator must use the authority provided in paragraph (e) to
request approval from the FAA. This approval may address either no
action, if the current configuration eliminates the unsafe
condition, or different actions necessary to address the unsafe
condition described in this AD. Such a request should include an
assessment of the effect of the changed configuration on the unsafe
condition addressed by this AD. In no case does the presence of any
modification, alteration, or repair remove any engine from the
applicability of this AD.
Compliance: Required as indicated, unless accomplished
previously.
To prevent engine failure due to incorrectly assembled
turbocharger oil outlet check valve, which could result in complete
engine failure, accomplish the following:
(a) Prior to further flight, determine if the turbocharger oil
outlet check valve has been installed or repaired on or after August
1, 1994. This AD is not applicable to engines that did not have the
turbocharger oil outlet check valve installed or repaired on or
after August 1, 1994.
(b) Prior to further flight, inspect the turbocharger oil outlet
check valve, TCM P/N 641068, in accordance with section B of
Teledyne Continental Motors (TCM) Critical Service Bulletin (CSB)
95-1A, Revision A, dated April 5, 1995, and replace any check valve
with an ink stamped date code of A3Q94, A4Q94 or A1Q95, or with no
readable date code, with a serviceable check valve as defined in
paragraph (c) of this AD.
(c) For the purpose of this AD, serviceable turbocharger oil
outlet check valve is defined as one with a date stamp code
indicating that it was manufactured before July 1, 1994, i.e.,
A2Q94, or earlier, or that it was manufactured after March 31, 1995,
i.e., A2Q95, or later.
(d) Install replacement valve in the turbocharger oil outlet
line with the flow arrow on the valve body pointing in the direction
of oil flow toward the scavenge pump in accordance with section B of
TCM CSB95-1A, Revision A, dated April 5, 1995.
(e) An alternative method of compliance that provides an
acceptable level of safety may be used if approved by the Manager,
Atlanta Aircraft Certification Office. The request should be
forwarded through an appropriate FAA Maintenance Inspector, who may
add comments and then send it to the Manager, Atlanta Aircraft
Certification Office.
