Airworthiness Directives; Avions Mudry et Cie Model CAP 10B
Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment supersedes Airworthiness Directive (AD) 93-10-
11, which currently requires installing an inspection opening in the
wing, repetitively inspecting the upper wing spar cap for cracks, and
repairing any cracks on all Avions Mudry et Cie (Avions) Model CAP 10B
airplanes. This AD will retain the same actions already required by AD
93-10-11, and will add inspecting, and repairing if necessary, the
lower surface of the wing spar. 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 structural cracks in the wing spar, which could lead to loss of
a wing and loss of control of the airplane.
DATES: Effective July 17, 1998.
The incorporation by reference of Avions Mudry & Cie Service
Bulletin CAP10B No. 16 (ATA 57-004), dated April 27, 1992, as listed in
the regulations, was previously approved by the Director of the Federal
Register, as of July 23, 1993 (58 FR 31342, June 2, 1993).
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of July 17, 1998.

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 all Avions Model CAP
10B airplanes was published in the Federal Register as a notice of
proposed rulemaking (NPRM) on March 26, 1998 (63 FR 14660). The
proposed AD would supersede AD 93-10-11, Amendment 39-8592 (58 FR
31342, June 2, 1993) with a new AD that would require installing an
inspection opening in the wing, repetitively inspecting the upper and
lower wing spars for structural cracking, and if any cracks are found,
repairing the cracks in accordance with a repair method provided by the
[[Page 31105]]
manufacturer through the FAA. The difference between the actions
proposed in the NPRM and AD 93-10-11 is the addition of the inspections
and possible repairs of the lower wing spar.
Accomplishment of the proposed action as specified in the NPRM
would be in accordance with Avions Mudry & Cie Service Bulletin No. 15,
CAP10B-57-003, Revision 1, dated April 3, 1996, and Avions SB CAP 10B
No. 16 (ATA 57-004), dated April 27, 1992.
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 37 airplanes in the U.S. registry will be
affected by this AD, that it will take approximately 5 workhours per
airplane to accomplish this action, and that the average labor rate is
approximately $60 an hour. Based on these figures, the total cost
impact of this AD on U.S. operators is estimated to be $11,100, or $300
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.

Adoption of the Amendment

Administrator, the Federal Aviation Administration amends part 39 of
the Federal Aviation Regulations (14 CFR part 39) as follows:

Sec. 39.13 [Amended]
2. Section 39.13 is amended by removing Airworthiness Directive
(AD) 93-10-11, Amendment No. 39-8592, and by adding a new AD to read as

126-AD; Supersedes AD 93-10-11, Amendment 39-8592.
Applicability: Model CAP 10B airplanes, all serial numbers,
certificated in any category.
Note 1: This AD applies to each airplane identified in the
preceding applicability provision, 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 the unsafe condition has not been
eliminated, the request should include specific proposed actions to
address it.
Compliance: Required as indicated in the body of this AD, unless
already accomplished.
To prevent structural cracks in the wing spars, which could lead
to loss of a wing and loss of control of the airplane, accomplish
the following:
(a) For airplanes having a serial number of 263 or lower, within
the next 100 hours time-in-service (TIS) after July 23, 1993 (the
effective date of AD 93-10-11, Amendment 39-8592), install a
permanent inspection opening in each wing in accordance with the
Technical Instructions section of Avions Mudry & Cie (Avions)
Service Bulletin (SB) CAP 10B No. 16 (ATA 57-004), dated April 27,
1992.
Note 2: The installation specified in paragraph (a) of this AD
is incorporated during production for airplanes having a serial
number of 264 or higher.
(b) For all serial numbers, within the next 100 hours TIS after
the effective date of this AD, or within the next 1,000 hours TIS
after the last inspection required in accordance with AD 93-10-11,
Amendment 39-8592, whichever occurs later, unless already
accomplished, and thereafter at intervals not to exceed 1,000 hours
TIS, inspect the upper and lower wing surfaces of both wing spars
for cracks in accordance with Avions SB No. 15, CAP10B-57-003,
Revision 1, dated April 3, 1996.
(c) If any cracks are found, prior to further flight, repair the
cracks with a repair scheme obtained from the manufacturer through
the FAA Project Officer at the Small Airplane Directorate, 1201
Walnut, suite 900, Kansas City, Missouri 64106.
Note 3: The compliance times required in this AD take precedence
over the compliance times stated in Avions SB No. 15, CAP10B-57-003,
Revision 1, dated April 3, 1996.
(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.
(e) An alternative method of compliance or adjustment of the
compliance times that provides an equivalent level of safety may be
approved by the Manager, Small Airplane Directorate, 1201 Walnut, suite
900, Kansas City, Missouri 64106.
(1) The request shall be forwarded through an appropriate FAA
Maintenance Inspector, who may add comments and then send it to the
Manager, Small Airplane Directorate.
(2) Alternative methods of compliance approved in accordance with
AD 93-10-11 are not considered approved as alternative methods of
compliance for this AD.
Note 4: Information concerning the existence of approved
alternative methods of compliance with this AD, if any, may be
obtained from the Small Airplane Directorate.

15, CAP10B-57-003, Revision 1, dated April 3, 1996, and Avions SB
