Airworthiness Directives; Anjou Aeronautique Safety Belts and 
Restraint Systems

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA adopts a new airworthiness directive (AD) for certain 
Anjou Aeronautique (ANJOU) (formerly TRW Repa S.A., formerly L'AIGLON) 
safety belts and restraint systems that are installed in aircraft. This 
AD requires you to inspect safety belts and restraint systems for 
defects and service life limits, and, if necessary, repair safety belts 
and restraint systems that have not reached service life limits; and 
replace safety belts and restraint systems that have reached service 
life limits. This AD is the result of reports of inadvertent unbuckling 
of the ANJOU seat belts and two safety recommendations to take AD 
action. We are issuing this AD to detect and correct defective safety 
belts and restraint systems, which could result in failure of the 
safety belts and restraint systems. This failure could lead to lack of 
occupant restraint during normal or crash loads.

DATES: This AD becomes effective on February 17, 2004.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the regulation as of 
February 17, 2004.

SUPPLEMENTARY INFORMATION:

Discussion

What Events Have Caused This AD?

    The FAA issued Special Airworthiness Information Bulletin (SAIB) 
Number CE-02-44, dated September 4, 2002, for SOCATA--Groupe 
AEROSPATIALE (SOCATA) Model TBM 700 airplanes, concerning ANJOU seat 
belts. At that time, FAA did not make a determination of an unsafe 
condition and take AD action.
    Later, FAA issued SAIB Number CE-03-06, dated November 7, 2002, for 
SOCATA Rallye 150T, Rallye 150ST, Rallye 235E, and Rallye 235C 
airplanes, concerning ANJOU seat belts. Again, FAA then did not make a 
determination of an unsafe condition and take AD action.
    We continued to receive field reports of inadvertent unbuckling of 
the ANJOU seat belts. The FAA received two safety recommendations to 
take AD action (NPRM) to propose to require replacement of certain 
safety belts and restraint systems.

[[Page 75392]]

    In light of the field reports and safety recommendations, 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 SOCATA Models TB 9, 
TB 10, TB 20, TB 21, TB 200, TMB 700, Rallye 100S, Rallye 150T, Rallye 
150ST, Rallye 235E, and Rallye 235C airplanes. This proposal was 
published in the Federal Register as a notice of proposed rulemaking 
(NPRM) on March 7, 2003 (68 FR 11015). The NPRM proposed to require you 
to replace certain safety belts and restraint systems.
    Comments received on the NPRM suggest that FAA withdraw the 
proposal and that FAA consider issuing a new NPRM to propose that you:

--inspect certain ANJOU safety belts and restraint systems that are 
installed in airplanes for defects and service life limits;
--repair defective safety belts and restraint systems that have not 
reached service life limits; and
--replace safety belts and restraint systems that have reached service 
life limits.

    We agree, and therefore, are withdrawing that NPRM.

What Is the Potential Impact if FAA Took No Action?

    These defective safety belts and restraint systems could result in 
failure of the safety belts and restraint systems. This failure could 
lead to lack of occupant restraint during normal or crash loads.

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 ANJOU (formerly TRW Repa S.A., formerly L'AIGLON) safety belts 
and restraint systems that are installed in aircraft. This proposal was 
published in the Federal Register as a notice of proposed rulemaking 
(NPRM) on September 2, 2003 (68 FR 52145). The NPRM proposed to inspect 
safety belts and restraint systems for defects and service life limits, 
and, if necessary, repair safety belts and restraint systems that have 
not reached service life limits; and replace safety belts and restraint 
systems that have reached service life limits.

Comments

Was the Public Invited To Comment?

    We gave the public the opportunity to participate in the 
development of this AD. We received no comments on the proposal or on 
the determination of the cost to the public.

Conclusion

What Is FAA's Final Determination on This Issue?

    We have carefully reviewed the available data and determined that 
air safety and the public interest require adopting the AD 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.

Changes to 14 CFR Part 39--Effect on the AD

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

    On July 10, 2002, the FAA published a new version of 14 CFR part 39 
(67 FR 47997, July 22, 2002), which governs the FAA's AD system. This 
regulation now includes material that relates to altered products, 
special flight permits, and alternative methods of compliance. 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.

Costs of Compliance

How Many Airplanes Does This AD Impact?

    We estimate that this AD affects 617 aircraft in the U.S. registry 
that could have the affected ANJOU safety belts and restraint systems 
installed. Some aircraft have more than one unit installed.

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

    We estimate the following costs to accomplish the inspection and 
repair:

------------------------------------------------------------------------
                                                          Total cost per
                                                          6 safety belts
            Labor cost                  Parts cost        and restraint
                                                             systems
------------------------------------------------------------------------
1 workhour per 6 safety belts and  No cost.............             $65
 restraint systems x $65 per hour
 = $65.
------------------------------------------------------------------------

    The applicable service information identifies that replacement 
parts are available free of charge. For replacement of a safety belt 
assembly, the parts cost is approximately $150 per seat belt assembly. 
The number of installed safety belts and restraint systems may vary by 
individual aircraft configuration. Therefore, we have no way of 
determining the replacement cost for this AD.

Compliance Time of This AD

What Is the Compliance Time of This AD?

    The compliance time of this AD is within 50 hours time-in-service 
(TIS) or 4 calendar months after the effective date of this AD, 
whichever occurs first.

Why Is the Compliance Time of This AD Presented in Both Hours TIS and 
Calendar Time?

    Defective safety belts and restraint systems are a direct result of 
use of the safety belts and restraint systems. However, defective 
safety belts and restraint systems are not necessarily a result of 
repetitive airplane operation. For example, defective safety belts and 
restraint systems could occur on an affected airplane within a short 
period of airplane operation while you could operate another affected 
airplane for a considerable amount of time without experiencing 
defective safety belts and restraint systems. Therefore, to assure that 
any defective safety belt and restraint system is detected and 
corrected in a timely manner without inadvertently grounding any of the 
affected airplanes, we are using a compliance time based upon both 
hours TIS and calendar time.

Regulatory Findings

Will This AD Impact Various Entities?

    We have determined that this AD will not have federalism 
implications under Executive Order 13132. This AD 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.

[[Page 75393]]

Will This AD Involve a Significant Rule or Regulatory Action?

    For the reasons discussed above, I certify that this AD:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the 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.
    We prepared a summary of the costs to comply with this AD and 
placed it in the AD Docket. You may get a copy of this summary by 
sending a request to us at the address listed under ADDRESSES. Include 
``AD Docket No. 2003-CE-31-AD'' in your request.
