Airworthiness Directives; SOCATA--Groupe AEROSPATIALE Model TBM 
700 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) Model TBM 700 
airplanes. This AD requires you to apply Loctite on attaching bolt/
screw threads of inboard, central, and outboard carriages; increase 
tightening torques of associated hardware; and replace central carriage 
attaching bolts. 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 
loose, or the loss of, flap attaching bolts/screws, which could cause 
rough or irregular control. Such rough or irregular control could lead 
to the loss of control of the airplane.

DATES: This AD becomes effective on April 27, 2001.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the regulations as of April 
27, 2001.

SUPPLEMENTARY INFORMATION:

Discussion

    What events have caused this AD? The Direction Generale de 
l'Aviation Civile (DGAC), which is the airworthiness authority for 
France, recently notified FAA that an unsafe condition may exist on 
certain Socata Model TBM 700 airplanes. The DGAC reports two 
occurrences on Socata model TBM 700 airplanes where, following a 
flight, a screw of a flap attachment fitting was found partly unscrewed 
and another was missing. These occurrences are the result of flap 
vibration.
    What are the consequences if the condition is not corrected? Loose 
or the loss of flap attaching bolts/screws could result in rough or 
irregular control. Such rough or irregular control could lead to loss 
of control of 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 certain Socata Model TBM 700 
airplanes. This proposal was published in the Federal Register as a 
notice of proposed rulemaking (NPRM) on January 2, 2001 (66 FR 64). The 
NPRM proposed to require you to apply Loctite on attaching bolt/screw 
threads of inboard, central, and outboard carriages; increase 
tightening torques of associated hardware; and replace central carriage 
attaching bolts.
    Was the public invited to comment? Interested persons were 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.
    Socata has revised Service Bulletin No. SB 70-087 57, dated 
September 2000 (Amendment 1, dated November 2000), to incorporate minor 
procedural changes. This AD requires no further action if the original 
service bulletin is accomplished.

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 the addition of 
the revised service information and minor editorial corrections. We 
determined that this addition and 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

    How many airplanes does this AD impact? We estimate that this AD 
affects 75 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:

----------------------------------------------------------------------------------------------------------------
          Labor cost              Parts cost        Total cost per airplane       Total cost on U.S.  operators
----------------------------------------------------------------------------------------------------------------
6 workhours  x  $60 per hour              $10   $360 + $10 = $370                $370  x  75 = $27,750
 = $360.
----------------------------------------------------------------------------------------------------------------

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.

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

    (e) Can I comply with this AD in any other way? You may use an 
alternative method of compliance or adjust the compliance time if:
    (1) Your alternative method of compliance provides an equivalent 
level of safety; and
    (2) The Manager, Small Airplane Directorate, approves your 
alternative. Submit your request through an FAA Principal 
Maintenance Inspector, who may add comments and then send it to the 
Manager, Small Airplane Directorate.

    Note 1: This AD applies to each airplane identified in paragraph 
(a) of this AD, regardless of whether it has been modified, altered, 
or repaired in the area subject to the requirements of this AD. For 
airplanes that have been modified, altered, or repaired so that the 
performance of the requirements of this AD is affected, the owner/
operator must request approval for an alternative method of 
compliance in accordance with paragraph (e) of this AD. The request 
should include an assessment of the effect of the modification, 
alteration, or repair on the unsafe condition addressed by this AD; 
and, if you have not eliminated the unsafe condition, specific 
actions you propose to address it.
