RIN 2120-AA64
Airworthiness Directives; Iniziative Industriali Italiane S.p.A.
Models Sky Arrow 650 TC and 650 TCN 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 certain Iniziative Industriali Italiane S.p.A.
(3I) Models Sky Arrow 650 TC and 650 TCN airplanes. This proposed AD
would require you to modify the nose gear support bulkhead (STA600).
This proposed AD is the result of mandatory continuing airworthiness
information (MCAI) issued by the airworthiness authority for Italy. The
actions specified by this proposed AD are intended to prevent failure
of the nose gear support bulkhead (STA600). Such failure could lead to
loss of control of the airplane during landing or take-off.
DATES: The Federal Aviation Administration (FAA) must receive any
comments on this proposed rule on or before May 9, 2003.
ADDRESSES: Submit comments to FAA, Central Region, Office of the
Regional Counsel, Attention: Rules Docket No. 2003-CE-11-AD, 901
Locust, Room 506, Kansas City, Missouri 64106. You may view any
comments at this location between 8 a.m. and 4 p.m., Monday through
Friday, except Federal holidays. You may also send comments
electronically to the following address: 9-ACE-7-Docket@faa.gov.
Comments sent electronically must contain ``Docket No. 2003-CE-11-AD''
in the subject line. If you send comments electronically as attached
electronic files, the files must be formatted in Microsoft Word 97 for
Windows or ASCII text.
You may get service information that applies to this proposed AD
from Iniziative Industriali Italiane S.p.A., Corso Trieste, n. 150,
00198 Rome, Italy; telephone: 06 84.15.821; facsimile: 06 855.71.62.

Discussion
What Events Have Caused This Proposed AD?
The Ente Nazionale per l'Aviazione Civile (ENAC), which is the
airworthiness authority for Italy, recently notified FAA that an unsafe
condition may exist on certain Iniziative Industriali Italiane S.p.A.
(3I) Models Sky Arrow 650 TC and 650 TCN airplanes. The ENAC reports
that data collected on in-service airplanes show that cracks have been
detected on the nose gear support bulkhead (STA600) of several
airplanes with high operating time on grass airfields and at flight
schools where activity of hard landings have occurred.
What Are the Consequences if the Condition Is Not Corrected?
If not corrected, the nose gear support bulkhead (STA600) could
fail. Such failure could lead to loss of control of the airplane during
landing or take-off.
Is There Service Information That Applies to This Subject?
Iniziative Industriali Italiane S.p.A. (3I) has issued 3i Service
Bulletin SB-C No. 02/02, dated October 15, 2002.
What Are the Provisions of This Service Information?
The service bulletin includes procedures for modifying the nose
gear support bulkhead (STA600).
What Action Did the ENAC Take?
The ENAC classified this service bulletin as mandatory and issued
Italian AD Number 2002-591, dated November 29, 2002, in order to ensure
the continued airworthiness of these airplanes in Italy.
Was This in Accordance With the Bilateral Airworthiness Agreement?
These airplane models are manufactured in Italy and are type
certificated for operation in the United States under the provisions of
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and
the applicable bilateral airworthiness agreement.
Pursuant to this bilateral airworthiness agreement, the ENAC has
kept FAA informed of the situation described above.
The FAA's Determination and an Explanation of the Provisions of This
Proposed AD
What Has FAA Decided?
The FAA has examined the findings of the ENAC; reviewed all
available information, including the service information referenced
above; and determined that:
--The unsafe condition referenced in this document exists or could
develop on other Iniziative Industriali Italiane S.p.A. (3I) Models Sky
Arrow 650 TC and 650 TCN airplanes of the same type design that are on
the U.S. registry;
--The actions specified in the previously-referenced service
information should be accomplished on the affected airplanes; and
--AD action should be taken in order to correct this unsafe condition.
What Would This Proposed AD Require?
This proposed AD would require you to incorporate the actions in
the previously-referenced service bulletin.
How Does the Revision to 14 CFR Part 39 Affect This Proposed AD?
On July 10, 2002, FAA published a new version of 14 CFR part 39 (67
FR 47997, July 22, 2002), which governs FAA's AD system. This
regulation now includes material that relates to special flight
permits, alternative methods of compliance, and altered products. This
material previously was included in each individual AD. Since this
material is included in 14 CFR part 39, we will not include it in
future AD actions.
Cost Impact
How Many Airplanes Would This Proposed AD Impact?
We estimate that this proposed AD affects 10 airplanes in the U.S.
registry.
What Would Be the Cost Impact of This Proposed AD on Owners/Operators
of the Affected Airplanes?
We estimate the following costs to accomplish the proposed
modification:
----------------------------------------------------------------------------------------------------------------
Total cost on
Labor cost Parts cost Total cost per U.S.
airplane operators.
----------------------------------------------------------------------------------------------------------------
19 workhours x $60 = $1,140..................................... $100 $1,240 $12,400.
----------------------------------------------------------------------------------------------------------------
The proposed modification to the nose gear support bulkhead
(STA600) would require 39 hours for cure and post cure time.
Regulatory Impact
Would This Proposed AD Impact Various Entities?
The regulations proposed herein would not have a substantial direct
effect 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, it
is determined that this proposed rule would not have federalism
implications under Executive Order 13132.
Would This Proposed AD Involve a Significant Rule or Regulatory Action?
For the reasons discussed above, I certify that this proposed
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.
