14 CFR Part 39

[Docket No. 2002-CE-01-AD; Amendment 39-12744; AD 2002-09-11]
RIN 2120-AA64


Airworthiness Directives; SOCATA--Groupe AEROSPATIALE Model TBM 
700 Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment supersedes Airworthiness Directive (AD) 2001-
05-03, which applies to certain SOCATA--Groupe AEROSPATIALE (Socata) 
Model TBM 700 airplanes. AD 2001-05-03 currently 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. The French airworthiness 
authority has determined that certain service information referenced in 
AD 2001-05-03 be removed and additional inspection of the flap carriage 
attaching bolts, screws, and barrel nut be included. Therefore, this AD 
will retain the requirements of the current AD and will add the 
information communicated by the French airworthiness authority. The 
actions specified by this AD are intended to prevent the flap attaching 
bolts/screws from becoming loose and separating from the airplane, 
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 June 20, 2002.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the regulations as of June 
20, 2002.

SUPPLEMENTARY INFORMATION:

Discussion

    What events have caused this AD? Reports of occurrences on Socata 
Model TBM 700 airplanes where a screw of a flap attachment fitting was 
found partly unscrewed and another was missing caused us to issue AD 
2001-05-03, Amendment 39-12139 (66 FR 14308, March 12, 2001). The 
occurrences were the result of flap vibration. AD 2001-05-03 requires 
the following on Socata Model TBM 700 airplanes:

--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.

    Accomplishment of these actions is required in accordance with 
Socata Mandatory Service Bulletin SB 70-087 57, Amendment 1, dated 
November 2000, or Socata Mandatory Service Bulletin SB 70-087, dated 
September 2000.
    What has happened since AD 2001-05-03 to initiate this action? The 
Direction Generale de l'Aviation Civile (DGAC), which is the 
airworthiness authority for France, recently notified FAA of the need 
to change AD 2001-05-03. The DGAC reports the procedures in the 
original issue of Socata Mandatory Service Bulletin SB 70-087, dated 
September, 2000, do not correct the unsafe condition. The DGAC 
indicates that reference to this service information should be removed 
from the AD. In addition, the DGAC is requiring the barrel nut be 
inspected for correct installation, with corrective action as 
necessary, on certain Socata Model TBM 700 airplanes registered in 
France.
    What is the potential impact if FAA took no action? This condition, 
if not corrected, could result in the flap attaching bolts/screws 
becoming loose and separating from the airplane, which could cause 
rough or irregular control. Such rough or irregular control could lead 
to the 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 February 11, 2002 (67 FR 6207). 
The NPRM proposed to supersede AD 2001-05-03 with a new AD that would 
require you to:
--Inspect the flap carriage attaching bolts and screws for damage and 
replace as necessary;
--Apply Loctite on the attaching bolt and screw threads of inboard, 
central, and outboard carriages;
--Increase the tightening torques;
--Replace central carriage attaching bolts; and
--Inspect the barrel nut for correct positioning, and corrective action 
as necessary.

    The NPRM also proposed to remove compliance in accordance with the 
procedures in Socata Mandatory Service Bulletin SB 70-087 57, dated 
September 2000.
    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

[[Page 30542]]

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.

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 modifications:

----------------------------------------------------------------------------------------------------------------
                                                                Parts     Total cost per     Total cost on U.S.
                          Labor cost                             cost        airplane             operators
----------------------------------------------------------------------------------------------------------------
6 workhours  x  $60 per hour = $360..........................      $10   $360 + $10 = $370         $370  x  75 =
                                                                                                         $27.750
----------------------------------------------------------------------------------------------------------------

    The only difference between this AD and AD 2001-05-03 is the 
addition of the inspection of the flap carriage attachment bolts, 
screws, and barrel nut. The FAA has determined that the cost of this 
inspection is minimal and does not increase the cost impact over that 
already required by AD 2001-05-03.

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.
