14 CFR Part 39
[Docket No. 97-NM-64-AD; Amendment 39-10589; AD 98-13-01]
RIN 2120-AA64
Airworthiness Directives; Aerospatiale Model ATR42 and ATR72
Series Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD),
applicable to certain Aerospatiale Model ATR42 and ATR72 series
airplanes, that
[[Page 32610]]
requires replacement of the left longitudinal net of the forward cargo
compartment with a new reinforced net. This amendment is prompted by
issuance of mandatory continuing airworthiness information by a foreign
civil airworthiness authority. The actions specified by this AD are
intended to prevent blockage of the access door, which could restrict
access for crewmembers between the flight deck and the passenger
compartment during normal operations or an emergency evacuation.
DATES: Effective July 20, 1998.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of July 20, 1998.
ADDRESSES: The service information referenced in this AD may be
obtained from Aerospatiale, 316 Route de Bayonne, 31060 Toulouse, Cedex
03, France. This information may be examined at the Federal Aviation
Administration (FAA), Transport Airplane Directorate, Rules Docket,
1601 Lind Avenue, SW., Renton, Washington; or at the Office of the
Federal Register, 800 North Capitol Street, NW., suite 700, Washington,
DC.
FOR FURTHER INFORMATION CONTACT: Norman B. Martenson, Manager,
International Branch, ANM-116, FAA, Transport Airplane Directorate,
1601 Lind Avenue, SW., Renton, Washington 98055-4056; telephone (425)
227-2110; fax (425) 227-1149.
SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) to include an airworthiness
directive (AD) that is applicable to certain Aerospatiale Model ATR42
and ATR72 series airplanes was published in the Federal Register on
April 14, 1998 (63 FR 18155). That action proposed to require
replacement of the left longitudinal net of the forward cargo
compartment with a new reinforced net.
Comments
Interested persons have been afforded an opportunity to participate
in the making of this amendment. No comments were submitted in response
to the proposal or the FAA's determination of the cost to the public.
Explanation of Changes Made to Proposal
The FAA has revised the final rule to reflect a change of the
manufacturer's name referenced in the proposal for the service
bulletins from Aerospatiale to Avions de Transport Regional.
Conclusion
The FAA has determined that air safety and the public interest
require the adoption of the rule with the change previously described.
The FAA has determined that this change will neither increase the
economic burden on any operator nor increase the scope of this AD.
Cost Impact
The FAA estimates that 141 airplanes of U.S. registry will be
affected by this AD, that it will take approximately 1 work hour per
airplane to accomplish the required replacement, and that the average
labor rate is $60 per work hour. Required parts will be supplied by the
manufacturer at no cost to the operators. Based on these figures, the
cost impact of the AD on U.S. operators is estimated to be $8,460, or
$60 per airplane.
The cost impact figure discussed above is based on assumptions that
no operator has yet accomplished any of the requirements of this AD
action, and that no operator would accomplish those actions in the
future if this AD were not adopted.
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 final evaluation has been prepared for this action
and it is contained in the Rules Docket. A copy of it may be obtained
from the Rules Docket at the location provided under the caption

Adoption of the Amendment
Accordingly, pursuant to the authority delegated to me by the

98-13-01 Aerospatiale: Amendment 39-10589. Docket 97-NM-64-AD.
Applicability: Model ATR42-300 and -320 series airplanes, on
which Aerospatiale Modification 1878, 2482, 3193, or 8154 has not
been installed, or on which simultaneous installation of
Modifications 0481 and 0588 has not been accomplished; and Model
ATR72-102, -202, and -212 series airplanes on which Aerospatiale
Modification 2482, 3193, or 4648 has not been installed;
certificated in any category.
Note 1: This AD applies to each airplane identified in the
preceding applicability provision, regardless of whether it has been
otherwise 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 (c) 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 the unsafe condition has not been
eliminated, the request should include specific proposed actions to
address it.
Compliance: Required as indicated, unless accomplished
previously.
To prevent blockage of the access door, which could restrict
access for crewmembers between the flight deck and the passenger
compartment during normal operations or an emergency evacuation,
accomplish the following:
(a) Within 6 months after the effective date of this AD, replace
existing cargo nets with new improved cargo nets, in accordance with
paragraph (a)(1) or (a)(2) of this AD, as applicable.

cargo nets in accordance with Avions de Transport Regional Service
Bulletin ATR72-25-1052, dated February 11, 1997; or Revision 1,
dated July 1, 1997.
(b) As of the effective date of this AD, no person shall install
on any airplane any cargo net having one of the following part
numbers: 5366, 5367, 5370, 5375, or 5579.
[[Page 32611]]
(c) An alternative method of compliance or adjustment of the
compliance time that provides an acceptable level of safety may be
used if approved by the Manager, International Branch, ANM-116, FAA,
Transport Airplane Directorate. Operators shall submit their
requests through an appropriate FAA Principal Maintenance Inspector,
who may add comments and then send it to the Manager, International
Branch, ANM-116.
Note 2: Information concerning the existence of approved
alternative methods of compliance with this AD, if any, may be
obtained from the International Branch, ANM-116.
(d) Special flight permits may be issued in accordance with
sections 21.197 and 21.199 of the Federal Aviation Regulations (14
CFR 21.197 and 21.199) to operate the airplane to a location where
the requirements of this AD can be accomplished.
