Airworthiness Directives; Cessna Aircraft Company 180, 182, and
185 Series Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: This document proposes to adopt a new airworthiness directive
(AD) that would apply to all Cessna Aircraft Company (Cessna) 180, 182,
and 185 series airplanes equipped with wing extension supplemental type
certificate (STC) SA00276NY. The proposed action would require
inspecting between wing station (W.S.) 90 and W.S. 110 for an angle
stiffener at the lower wing spar splice. If the angle stiffener is not
installed, the proposed action would require installing a reinforcing
strap. The proposed action is the result of failed test results
revealing that the wings of these Cessna airplanes, without the
stiffener, do not meet the applicable design requirements after being
modified by the above STC. The actions specified by the proposed AD are
intended to prevent wing failure during flight, which, if not
corrected, could cause loss of control of the airplane.
DATES: Comments must be received on or before May 15, 1998.
ADDRESSES: Submit comments in triplicate to the Federal Aviation
Administration (FAA), Central Region, Office of the Regional Counsel,

Availability of NPRMs
Any person may obtain a copy of this NPRM by submitting a request
to the FAA, Central Region, Office of the Regional Counsel, Attention:
Rules Docket No. 97-CE-14-AD, Room 1558, 601 E. 12th Street, Kansas
City, Missouri 64106.
Discussion
The FAA has been notified by the Canadian civil airworthiness
authority, Transport Canada, that certain Cessna 180, 182, and 185
series airplanes, equipped with wing extensions by way of supplemental
type certificate (STC) SA00276NY, may not have had a wing stiffener
installed at factory. This condition has been discovered on several of
these airplanes during routine inspections. Since this discovery,
further investigation has shown that without the wing stiffener, the
wing is susceptible to structural failure. Both the FAA and Transport
Canada have been in contact with the manufacturer of this particular
STC and have approved an alternative to the wing stiffener. Tests have
shown that the wing would be stabilized by installing a wing
reinforcement strap to add strength to this area of the wing, if it is
without the wing stiffener.
Relevant Service Information
Air Research Technology, Inc. has issued Service Bulletin No. SB-1-
96, Issue 1, dated April 11, 1996, which specifies procedures for
visually inspecting the underside of the wing, aft of the spar, closest
to where the strut connects to the wing, for the installation of an
angle stiffener along the lower spar cap between Wing Station (W.S.) 90
and W.S. 110. If an angle stiffener is not installed, then the service
information provides procedures for installing a stainless steel
reinforcement strap on the underside of the wing, along the spar, at
W.S. 100.50.
The FAA's Determination
After examining the circumstances and reviewing all available
information, including the relevant service information, related to the
incidents described above, the FAA has determined that AD action should
be taken to prevent wing failure during flight, which, if not corrected
could cause loss of control of the airplane.
Explanation of the Provisions of the Proposed AD
Since an unsafe condition has been identified that is likely to
exist or develop in other (Cessna) 180, 182, and 185 series airplanes
equipped with wing extension STC SA00276NY, the proposed AD would
require inspecting the inside of the underside of the wing, near Wing
Station (W.S.) 100, for an angle stiffener. If an angle stiffener is
not installed, the proposed AD would require installing a reinforcement
strap along the lower wing spar.
Cost Impact
The FAA estimates that there are 55 airplanes in the U.S. registry
that would be affected by the proposed AD, that it would take
approximately 1 workhour for the initial inspection and 7 workhours for
the installation of the reinforcement strap per airplane, and that the
average labor rate is approximately $60 an hour. Parts are supplied by
the wing extension kit manufacturer at no cost to the owner/operator.
Based on these figures, the total cost impact of the proposed AD on
U.S. operators is estimated to be $26,400 or $480 per airplane. The FAA
has no way to determine the number of owners/operators who may have
already accomplished the proposed action, and would presume that none
of the owners/operators of the affected airplanes have accomplished the
proposed action.
Regulatory Impact
The regulations proposed herein would 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
proposal would not have sufficient federalism implications to warrant
the preparation of a Federalism Assessment.
For the reasons discussed above, I certify that this action (1) is
not a ``significant regulatory action'' under Executive Order 12866;
(2) is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979); and (3) if promulgated,
will not have a significant economic impact, positive or negative, on a
substantial number of small entities under the criteria of the
Regulatory Flexibility Act. A copy of the draft regulatory evaluation
prepared for this action has been placed in the Rules Docket. A copy of
it may be obtained by contacting the Rules Docket at the location
provided under the caption ADDRESSES.
