Airworthiness Directives; Cessna Aircraft Company 180, 182, and
185 Series Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD) that
applies to all Cessna Aircraft Company (Cessna) 180, 182, and 185
series airplanes that have wing extension supplemental type certificate
(STC) SA00276NY or supplemental type approval (STA) SA93-136
incorporated. This AD requires 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, this AD requires installing a
reinforcing strap. This AD 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 this AD are
intended to prevent wing failure during flight caused by the absence of
an angle stiffener, which could cause loss of control of the airplane.
DATES: Effective September 21, 1998.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of September 21, 1998.

SUPPLEMENTARY INFORMATION:
Events Leading to the Issuance of This AD
A proposal to amend part 39 of the Federal Aviation Regulations (14
CFR part 39) to include an AD that would apply to all Cessna 180, 182,
and 185 series airplanes equipped with wing extension STC SA00276NY or
STA SA93-136 was published in the Federal Register as a notice of
proposed rulemaking (NPRM) on March 19, 1998 (63 FR 13374). The NPRM
proposed to 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. Accomplishment of the
proposed action as specified in the NPRM would be in accordance with
Air Research Technology Service Bulletin No. SB-1-96, Issue 1, dated
April 11, 1996.
The NPRM was 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 or
STA.
Interested persons have been afforded an opportunity to participate
in the making of this amendment. No comments were received on the
proposed rule or the FAA's determination of the cost to the public.
The FAA's Determination
After careful review of all available information related to the
subject presented above, the FAA has determined that air safety and the
public interest require the adoption of the rule as proposed except for
minor editorial corrections. The FAA has determined that these minor
corrections will not change the meaning of the AD and will not add any
additional burden upon the public than was already proposed.
Cost Impact
The FAA estimates that there are 55 airplanes in the U.S. registry
that will be affected by this AD, that it will 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 this 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 this action, and will presume that none of the owners/
operators of the affected airplanes have accomplished this action.
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.
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) 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 final evaluation prepared for this
action is contained in the Rules Docket. A copy of it may be obtained
by contacting the Rules Docket at the location provided under the
caption ADDRESSES.

alternative method of compliance in accordance with paragraph (d) 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 within the next 50 hours time-in-service
(TIS) after the effective date of this AD, unless already
accomplished.
To prevent wing failure during flight caused by the absence of
an angle stiffener, which could cause loss of control of the
airplane, accomplish the following:
(a) Inspect inside the left and right wings, aft of the spar,
closest to where the strut connects to the wing, for an angle
stiffener along the lower spar cap between Wing Station (W.S.) 90

Instructions of Air Research Technology, Inc. (ART) Service Bulletin
(SB) No. SB-1-96, Issue 1, dated April 11, 1996.
(b) If an angle stiffener is not installed, prior to further
flight, install a stainless steel reinforcement strap on the
underside of each wing, along the spar at W.S. 100.50 in accordance
with Part B of the Accomplishment Instructions of ART SB No. SB-1-
96, Issue 1, dated April 11, 1996.
(c) 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.
