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 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-10-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. You may also view this information at the Rules Docket at the address above.

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.
