Airworthiness Directives; SOCATA-Groupe AEROSPATIALE Models TB9, 
TB10, TB20, TB21, and TB200 Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD) that 
applies to certain Socata-Groupe Aerospatiale (Socata) Models TB9, 
TB10, TB20, TB21, and TB200 airplanes. This AD requires inspecting the 
bolts and spacers of the upper attachments of the front belts for 
cracks, dents, etc. (damage); replacing any damaged bolts or spacers; 
incorporating a front belts upper attachment reinforcement kit; and 
reconditioning the belts. This AD is the result of mandatory continuing 
airworthiness information (MCAI) issued by the airworthiness authority 
for France. The actions specified by this AD are intended to prevent 
failure of the upper seat belt attachment caused by excessive loads on 
the upper attachment of the belt, which could result in bodily injury 
to the occupants during landing.

DATES: Effective March 24, 1998.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of March 24, 1998.

ADDRESSES: Service information that applies to this AD may be obtained 
from Socata-Groupe Aerospatiale, Socata Product Support, Aeroport

SUPPLEMENTARY INFORMATION:

Events Leading to the Issuance of This AD

    A proposal to amend part 39 of the Federal Aviation Regulations (14 
CFR part 39) to include an AD that would apply to certain Socata Models 
TB9, TB10, TB20, TB21, and TB200 airplanes was published in the Federal 
Register as a notice of proposed rulemaking (NPRM) on November 7, 1997 
(62 FR 60189). The NPRM proposed to require inspecting the bolts and 
spacers of the upper attachments of the front belts for cracks, dents, 
etc. (damage); replacing any damaged bolts or spacers; incorporating a 
front belts upper attachment reinforcement kit; and reconditioning the 
belts. Accomplishment of the proposed action as specified in the NPRM 
would be in accordance with Socata Service Bulletin No. SB 10-103 and 
Socata Service Bulletin No. SB 10-104, both dated June 1996.
    The NPRM was the result of mandatory continuing airworthiness 
information (MCAI) issued by the airworthiness authority for France.
    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. No comments were received on the 
proposed rule or the FAA's determination of the cost to the public.

The FAA's Determination

    After careful review of all available information related to the 
subject presented above, the FAA has determined that air safety and the 
public interest require the adoption of the rule as proposed except for 
minor editorial corrections. The FAA has determined that these minor 
corrections will not change the meaning of the AD and will not add any 
additional burden upon the public than was already proposed.

Cost Impact

    The FAA estimates that 320 airplanes in the U.S. registry will be 
affected by this AD.
    Accomplishing this replacement will take approximately 3 workhours 
per airplane, at an average labor rate of approximately $60 an hour. 
Parts to accomplish this AD cost approximately $300. Based on these 
figures, the total cost impact of this AD on U.S. operators is 
estimated to be $153,600, or $480 per airplane.

Regulatory Impact

    The regulations adopted herein will not have substantial direct 
effects 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, in 
accordance with Executive Order 12612, it is determined that this final 
rule does not have sufficient federalism implications to warrant the 
preparation of a Federalism Assessment.
    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.
