Airworthiness Directives; AERMACCI S.p.A. Models S.208 and S.208A
Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD) that
applies to all AERMACCI S.p.A. Models S.208 and S.208A airplanes. This
AD requires inspecting the landing gear rod springs to assure they are
made with a wire diameter of 4.5 millimeters (mm), and replacing any
that have a wire diameter of 4.0 mm. This AD is the result of mandatory
continuing airworthiness information (MCAI) issued by the airworthiness
authority for Italy. The actions specified by this AD are intended to
prevent failure of the landing gear caused by an insufficient wire
diameter of the rod springs, which could result in loss of control of
the airplane during landing operations.
DATES: Effective May 26, 1998.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director
[[Page 17317]]
of the Federal Register as of May 26, 1998.
ADDRESSES: Service information that applies to this AD may be obtained
from SIAI Marchetti S.p.A., Product Support Department, Via
Indipendenza 2, 21018 Sesto Calende (VA), Italy; telephone: +39-331-

examined at the Federal Aviation Administration (FAA), Central Region,
Office of the Regional Counsel, Attention: Rules Docket No. 97-CE-140-
AD, Room 1558, 601 E. 12th Street, Kansas City, Missouri 64106; or at

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 AERMACCI S.p.A.
Models S.208 and S.208A airplanes was published in the Federal Register
as a notice of proposed rulemaking (NPRM) on February 2, 1998 (63 FR
5324). The NPRM proposed to require inspecting the landing gear rod
springs to assure they are made with a wire diameter of 4.5 millimeters
(mm), and replacing any that have a wire diameter of 4.0 mm.
Accomplishment of the proposed action as specified in the NPRM would be
in accordance with SIAI Marchetti S.p.A. Service Bulletin No. 205B59,
dated July 29, 1995.
The NPRM was the result of mandatory continuing airworthiness
information (MCAI) issued by the airworthiness authority for Italy.
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 6 airplanes in the U.S. registry will be
affected by this AD, that it will take approximately 9 workhours per
airplane to accomplish the action required by this AD, and that the
average labor rate is approximately $60 an hour. Parts cost
approximately $15 per airplane. Based on these figures, the total cost
impact of this AD on U.S. operators is estimated to be $3,330, or $555
per airplane. This figure is based on the presumption that all of the
affected airplanes will have landing gear rod springs with an incorrect
diameter, and will require replacement of these rod springs.
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.

Adoption of the Amendment
Accordingly, pursuant to the authority delegated to me by the
Administrator, the Federal Aviation Administration amends part 39 of
the Federal Aviation Regulations (14 CFR part 39) as follows:
PART 39--AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
2. Section 39.13 is amended by adding a new airworthiness directive
(AD) to read as follows:
98-08-04 AERMACCI S.P.A.: Amendment 39-10453; Docket No. 97-CE-140-
AD.
Applicability: Models S.208 and S.208A airplanes, all serial
numbers, certificated in any category.
Note 1: This AD applies to each airplane 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 airplanes 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 (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 as indicated in the body of this AD, unless
already accomplished.
To prevent failure of the landing gear caused by an insufficient
wire diameter of the rod springs, which could result in loss of
control of the airplane during landing operations, accomplish the
following:
(a) Within the next 100 hours time-in-service (TIS) after the
effective date of this AD, inspect the landing gear rod springs to
assure they are made with a wire diameter of 4.5 millimeters (mm).
Accomplish this inspection in accordance with SIAI Marchetti S.p.A.
Service Bulletin No. 205B59, dated July 29, 1995.
(b) If any landing gear rod springs are found to have a wire
diameter of 4.0 mm, prior to further flight after the inspection
required by paragraph (a) of this AD, replace these rod springs with
rod springs that have a wire diameter of 4.5 mm. Accomplish this
replacement in accordance with the applicable maintenance manual.
(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.
(d) An alternative method of compliance or adjustment of the
compliance times that provides an equivalent level of safety may be
approved by the Manager, Small Airplane Directorate, 1201 Walnut,
suite 900, Kansas City, Missouri 64106. The request shall be
forwarded through an appropriate FAA Maintenance Inspector, who may
add comments and then send it to the Manager, Small Airplane
Directorate.
Note 2: Information concerning the existence of approved
alternative methods of
[[Page 17318]]
compliance with this AD, if any, may be obtained from the Small
Airplane Directorate.
(e) Questions or technical information related to SIAI Marchetti
S.p.A. Service Bulletin No. 205B59, dated July 29, 1995, should be
directed to SIAI Marchetti S.p.A., Product Support Department, Via
Indipendenza 2, 21018 Sesto Calende (VA), Italy; telephone: +39-331-

examined at the FAA, Central Region, Office of the Regional Counsel,
Room 1558, 601 E. 12th Street, Kansas City, Missouri.
(f) The inspection required by this AD shall be done in
accordance with SIAI Marchetti S.p.A. Service Bulletin No. 205B59,
dated July 29, 1995. This incorporation by reference was approved by
the Director of the Federal Register in accordance with 5 U.S.C.
