Docket ID: [Docket No. 2003-CE-11-AD; Amendment 39-13206; AD 2003-13-06]

RIN ID: RIN 2120-AA64

NOTICE: RULES

ACTION: Airworthiness directives:

DOCUMENT ACTION: Final rule.

SUBJECT CATEGORY: Airworthiness Directives; Iniziative Industriali Italiane S.p.A. Models Sky Arrow 650 TC and 650 TCN Airplanes

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.

DOCUMENT 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 takeoff.

SUMMARY: Iniziative Industriali Italiane S.p.A.,

SUPPLEMENTAL INFORMATION

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 inservice 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 takeoff.

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: [[Page 37397]]
Total cost per Total cost on Labor cost Parts cost airplane U.S. operators 19 workhours x $60 = $1,140.................................. $100 $1,240 $12,400

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.
