AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: This document publishes in the Federal Register an amendment
adopting Airworthiness Directive (AD) 98-23-01, which was sent
previously to all known U.S. owners and operators of aircraft and
engines equipped with certain Parker Hannifin Airborne dry air pumps,
conversion kits, and coupling kits, utilizing part number (P/N) B1-19-1
flexible coupling that has a date code resembling a clockface and
indicating a manufacture date of either ``12/97'' or ``5-6/98''. This
AD requires replacing the affected flexible coupling with P/N B1-7-3
flexible coupling (part of Parker Hannifin flexible coupling kit,
Airborne P/N 350). The AD resulted from reports
[[Page 63785]]
of failure of the affected flexible coupling due to a manufacturing
defect of this coupling. The actions specified by this AD are intended
to prevent failure of the primary dry air pump caused by defective
flexible coupling, which could result in loss of primary attitude and
direction references during instrument flight rules (IFR) operations.
DATES: Effective November 20, 1998, to all persons except those to whom
it was made immediately effective by priority letter AD 98-23-01,
issued October 29, 1998, 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 November 20, 1998.
Comments for inclusion in the Rules Docket must be received on or
before January 5, 1999.
ADDRESSES: Submit comments in triplicate to the Federal Aviation
Administration (FAA), Central Region, Office of the Regional Counsel,

SUPPLEMENTARY INFORMATION:
Discussion
On October 29, 1998, the FAA issued priority letter AD 98-23-01,
which applies to aircraft or engines equipped with certain Parker
Hannifin Airborne dry air pumps, conversion kits, and coupling kits,
utilizing P/N B1-19-1 flexible coupling that has a date code resembling
a clockface and indicating a manufacture date of either ``12/97'' or
``5-6/98''. This AD requires replacing the affected flexible coupling
with P/N B1-7-3 flexible coupling (part of Parker Hannifin flexible
coupling kit, Airborne P/N 350), in accordance with Parker Hannifin
Airborne Service Letter No. 48, dated October 20, 1998.
That AD resulted from approximately 50 reports of failure of the
flexible coupling on certain Parker Hannifin Airborne dry air pumps,
conversion kits, and coupling kits installed in aircraft or engines. To
this date, no accidents have occurred due to the failure of this
coupling. This condition could result in loss of primary attitude and
direction references during instrument flight rules (IFR) operations.
This condition is attributed to a manufacturing defect of Lots 1
and 2 of the B1-19-1 flexible coupling. This coupling was shipped
between January 1, 1998, and October 13, 1998. Dry air pumps,
conversion kits, and flexible coupling kits that incorporate any of the
part numbers and serial numbers referenced in the Applicability section
of this AD could have this manufacturing defect.
Dry air pumps that could incorporate the part number (P/N) B1-19-1
flexible coupling are installed as original equipment on many
airplanes, particularly Cessna, Raytheon, Piper, and Mooney airplanes.
In addition, Parker Hannifin holds a parts manufacturer approval (PMA)
for field replacements. The dry air pumps are the primary vacuum source
on small single-engine airplanes and the secondary vacuum source on
larger twin-engine airplanes.
The affected flexible coupling was shipped from Parker Hannifin
between January 1, 1998, and October 13, 1998.
Airborne dry air pumps, conversion kits, or coupling kits that were
installed or modified prior to January 1, 1998, would not incorporate
the affected coupling. A check of the maintenance records would show
whether the dry air pump, conversion kit, or coupling kit was installed
or modified prior to January 1, 1998.
Those Airborne dry air pumps, conversion kits, or coupling kits
installed or modified between January 1, 1998, and October 13, 1998,
could incorporate the affected coupling, depending on when the material
was received. The coupling could be held as spares or obtained from
salvaged parts. For this reason, any dry air pump, conversion kit, or
coupling kit with flexible coupling, P/N B1-19-1, that was installed or
modified after January 1, 1998, could be affected by the above
condition. The flexible coupling has a date code that resembles a
clockface and indicates a manufacture date of either ``12/97'' or ``5-
6/98''.
Relevant Service Information
Parker Hannifin issued Airborne Service Letter No. 48, dated
October 20, 1998, which specifies procedures for:
--Removing the dry air pump from the aircraft;
--Inspecting and identifying the P/N B1-19-1 flexible coupling; and
--Replacing the P/N B1-19-1 flexible coupling with P/N B1-7-3 flexible
coupling (part of Parker Hannifin flexible coupling kit, Airborne P/N
350).
The FAA's Determination and Explanation of the AD
Since an unsafe condition has been identified that is likely to
exist or develop in other aircraft or engines equipped with the above-
referenced flexible coupling, the FAA issued priority letter AD 98-23-
01 to prevent failure of the primary dry air pump caused by defective
flexible coupling, which could result in loss of primary attitude and
direction references during IFR operations.
Determination of the Effective Date of the 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 by individual letters
issued on October 29, 1998, to all known U.S. operators of aircraft or
engines equipped with the above-referenced flexible coupling. These
conditions still exist, and the AD is hereby published in the Federal
Register as an amendment to section 39.13 of the Federal Aviation
Regulations (14 CFR 39.13) to make it effective as to all persons.
Comments Invited
Although this action is in the form of a final rule that involves
requirements affecting immediate flight safety and, thus, was not
preceded by notice and opportunity to 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 above. 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.
[[Page 63786]]
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 rule must submit a self-addressed,
stamped postcard on which the following statement is made: ``Comments
to Docket No. 98-CE-108-AD.'' The postcard will be date stamped and
returned to the commenter.
Regulatory Impact
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.

A'' in the serial number block.
Note 2: The affected flexible coupling was shipped from Parker
Hannifin between January 1, 1998, and October 13, 1998. Dry air
pumps, conversion kits, or coupling kits that were installed or
modified prior to January 1, 1998, would not incorporate the
affected coupling. This AD allows the aircraft owner or pilot to
check the maintenance records to determine whether the dry air pump,
conversion kit, or coupling kit was installed or modified since
January 1, 1998. See paragraph (d) of this AD for authorization.
Note 3: This AD applies to any aircraft or engine equipped with
Airborne dry air pumps, conversion kits, and coupling kits, that
have flexible coupling, part number
(P/N) B1-19-1. Aircraft or engines with the P/N B1-19-1 flexible
coupling are affected regardless of whether they have been modified,
altered, or repaired in the area subject to the requirements of this
AD. For aircraft or engines that have been modified, altered, or
repaired so that the performance of the requirements of this AD is
affected, the owner/operator must request approval for an
alternative method of compliance in accordance with paragraph (f) of
this AD. The request should include an assessment of the effect of
the modification, alteration, or repair on the unsafe condition
addressed by this AD; and, if the unsafe condition has not been
eliminated, the request should include specific proposed actions to
address it.
Compliance: Required as indicated in the body of this AD, unless
already accomplished.
To prevent failure of the primary dry air pump caused by
defective flexible coupling, which could result in loss of primary
attitude and direction references during instrument flight rules
(IFR) operations, accomplish the following:
(a) Within 2 calendar days after the effective date of this AD
or prior to further flight after the effective date of this AD,
whichever occurs later, replace any affected flexible coupling with
P/N B1-7-3 flexible coupling (part of Parker Hannifin flexible
coupling kit, Airborne P/N 350) in accordance withParker Hannifin
Airborne Service Letter No. 48, dated October 20, 1998.
(b) If parts have been ordered from Parker
Hannifin, but are not available, accomplish the following:
(1) Operate the aircraft in visual flight rules
(VFR) conditions only;
(2) Operate the aircraft during daytime hours only; and
(3) When parts become available, replace the coupling prior to
further flight.
(c) As of the effective date of this AD, no person shall
install, on any aircraft or engine,
[[Page 63787]]
any of the affected Airborne dry air pumps, conversion kits, and
coupling kits, with part number (P/N) B1-19-1 flexible coupling that
has a date code resembling a clockface on the coupling and
indicating a manufacture date of either ``12/97'' or ``5-6/98''.
(d) The owner/operator holding at least a private pilot
certificate as authorized by section 43.7 of the Federal Aviation
Regulations (14 CFR 43.7) may check the maintenance records to
determine whether the existing dry air pump, conversion kit, or
coupling kit was installed or modified since January 1, 1998. If the
dry air pump, conversion kit, or coupling kit was not installed or
modified since January 1, 1998, the AD does not apply and the owner/
operator must make an entry into the aircraft records showing
compliance with this AD in accordance with section 43.9 of the
Federal Aviation Regulations (14 CFR 43.9).
(e) Special flight permits may be issued in accordance with
sections 21.197 and 21.199 of the Federal Aviation Regulations (14
CFR 21.197 and 21.199) to operate the airplane to a location where
the requirements of this AD can be accomplished, provided that:
(1) The aircraft is operated in VFR conditions only; and
(2) The aircraft is operated during daytime hours only.
(f) An alternative method of compliance or adjustment of the
compliance times that provides an equivalent level of safety may be
approved by the Manager, Chicago Aircraft Certification Office
(ACO), 2300 E. Devon Avenue, Des Plaines, Illinois 60018. The
request shall be forwarded through an appropriate FAA Maintenance
Inspector, who may add comments and then send it to the Manager,
