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 all Iniziative Industriali Italiane S.p.A.
(3I) Models Sky Arrow 650 TC and 650 TCN airplanes. This proposed AD
would require you to repetitively inspect the engine mount for cracks
and modify or replace the engine mount if cracks are found. 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 detect and
correct cracks in the engine mount, which could result in failure of
the engine mount. Such failure could lead to separation of the engine
from the airplane.
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-10-AD, 901

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 all 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 shows that cracks have been
detected on the engine mount 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?
This condition, if not detected and corrected, could result in
failure of the engine mount. Such failure could lead to separation of
the engine from the airplane.
Is There Service Information That Applies to This Subject?
Iniziative Industriali Italiane S.p.A. has issued 3i Service
Bulletin SB-C No. 01/02, dated October 15, 2002.
What Are the Provisions of This Service Information?
The service bulletin includes procedures for:
--Repetitively inspecting the engine mount for cracks; and
--Modifying the engine mount if cracks are found.
What Action Did the ENAC Take?
The ENAC classified this service bulletin as mandatory and issued
Italian AD Number 2002-590, 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
Sec. 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.
What Are the Differences Between This Proposed AD, the ENAC AD, and the
Service Information?
The ENAC AD and the service information requires (on Italian-
registered airplanes) inspection within the next 10 hours time-in-
service (TIS) after the effective date of the AD. We propose a
requirement that you inspect within the next 50 hours TIS after the
effective date of this proposed AD. We do not have justification to
require this action within the next 10 hours TIS.
We use compliance times such as 10 hours TIS when we have
identified an urgent safety of flight situation. We believe that 50
hours TIS will give the owners or operators of the affected airplanes
enough time to have the proposed actions accomplished without
compromising the safety of the airplanes.
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
inspection:
----------------------------------------------------------------------------------------------------------------
Total cost per
Labor cost Parts cost airplane Total cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
1 workhour x $60 = $60.............. No parts required...... $60 $60 x 10 = $600.
----------------------------------------------------------------------------------------------------------------
We estimate the following costs to accomplish the necessary
modification:
[[Page 16224]]
------------------------------------------------------------------------
Total cost per
Labor cost Parts cost airplane
------------------------------------------------------------------------
14 workhours x $60 = $840............... $100 $940
------------------------------------------------------------------------
We estimate the following costs to accomplish any necessary
replacements that would be required based on the results of the
proposed inspection. We have no way of determining the number of
airplanes that may need such replacement:
------------------------------------------------------------------------
Total cost per
Labor cost Parts cost airplane
------------------------------------------------------------------------
11 workhours x $60 = $660............... $500 $1,160
------------------------------------------------------------------------
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.
