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: Final rule.

-----------------------------------------------------------------------

SUMMARY: This amendment adopts a new airworthiness directive (AD) that 
applies to certain Iniziative Industriali Italiane S.p.A. (3I) Models 
Sky Arrow 650 TC and 650 TCN airplanes. This AD requires you to modify 
the nose gear support bulkhead (STA600). 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 nose gear support bulkhead (STA600). 
Such failure could lead to loss of control of the airplane during 
landing or take-off.

DATES: This AD becomes effective on August 11, 2003.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the regulations as of 
August 11, 2003.

ADDRESSES: You may get the service information referenced in this AD 
from Iniziative Industriali Italiane S.p.A., Corso Trieste, n. 150,

SUPPLEMENTARY INFORMATION:

Discussion

What Events Have Caused This AD?

    The Ente Na[zacute]ionale 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 Is the Potential Impact if FAA Took No Action?

    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.

Has FAA Taken Any Action to This Point?

    We issued a proposal to amend part 39 of the Federal Aviation 
Regulations (14 CFR part 39) to include an AD that would apply to 
certain Iniziative Industriali Italiane S.p.A. (3I) Models Sky Arrow 
650 TC and 650 TCN airplanes. This proposal was published in the 
Federal Register as a notice of proposed rulemaking (NPRM) on April 3, 
2003 (68 FR 16220). The NPRM proposed to require you to modify the nose 
gear support bulkhead (STA600).

Was the Public Invited to Comment?

    The FAA encouraged interested persons to participate in the making 
of this amendment. We did not receive any comments on the proposed rule 
or on our determination of the cost to the public.

FAA's Determination

What Is FAA's Final Determination on This Issue?

    After careful review of all available information related to the 
subject presented above, we have determined that air safety and the 
public interest require the adoption of the rule as proposed except for 
minor editorial corrections. We have determined that these minor 
corrections:

--Provide the intent that was proposed in the NPRM for correcting the 
unsafe condition; and
--Do not add any additional burden upon the public than was already 
proposed in the NPRM.

How Does the Revision to 14 CFR Part 39 Affect This 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 Does This AD Impact?

    We estimate that this AD affects 10 airplanes in the U.S. registry.

What Is the Cost Impact of This AD on Owners/Operators of the Affected 
Airplanes?

    We estimate the following costs to accomplish the modification:

----------------------------------------------------------------------------------------------------------------

    The modification to the nose gear support bulkhead (STA600) 
requires 39 hours for cure and post cure time.

Regulatory Impact

Does This AD Impact Various Entities?

    The regulations adopted herein will 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 final rule does not have federalism 
implications under Executive Order 13132.

Does This AD Involve a Significant Rule or Regulatory Action?

    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.
