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 all Iniziative Industriali Italiane S.p.A. (3I) Models Sky 
Arrow 650 TC and 650 TCN airplanes. This AD requires you to 
repetitively inspect the engine mount for cracks and modify or replace 
the engine mount if cracks are

[[Page 37398]]

found. 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 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: 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.

SUPPLEMENTARY INFORMATION:

Discussion

What Events Have Caused This 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 Is the Potential Impact if FAA Took No Action?

    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.

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 all 
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 
16222). The NPRM proposed to require you to repetitively inspect the 
engine mount for cracks and modify or replace the engine mount if 
cracks are found.

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.

What Are the Differences Between This 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 require that you 
inspect within the next 50 hours TIS after the effective date of this 
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 these actions accomplished without compromising the 
safety of the airplanes.

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 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:

------------------------------------------------------------------------
                                                          Total cost per
              Labor cost                   Parts cost        airplane
------------------------------------------------------------------------
14 workhours x $60 = $840.............            $100             $940
------------------------------------------------------------------------


[[Page 37399]]

    We estimate the following costs to accomplish any necessary 
replacements that will be required based on the results of the 
inspection. We have no way of determining the number of airplanes that 
may need such replacement:

------------------------------------------------------------------------
                                                          Total cost per
              Labor cost                   Parts cost        airplane
------------------------------------------------------------------------
1 workhours x $60 = $660..............            $500           $1,160
------------------------------------------------------------------------

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.
