Airworthiness Directives; Aeromot-Industria Mecanico Metalurgica
Ltda. Model AMT-200 Powered Gliders
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD) that
applies to certain Aeromot-Industria Mecanico Metalurgica Ltda.
(Aeromot) Model AMT-200 powered gliders. This AD requires replacing
certain flexible hoses in the engine oil system with flexible hoses
with a larger internal diameter. This AD is the result of mandatory
continuing airworthiness information (MCAI) issued by the airworthiness
authority for Brazil. The actions specified by this AD are intended to
prevent inefficiency of the engine lubricating system because of
ineffective flexible hoses, which could result in an in-flight engine
shutdown with consequent loss of powered glider controllability.
DATES: Effective September 7, 1998.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of September 7, 1998.
ADDRESSES: Service information that applies to this AD may be obtained
from Grupo Aeromot, Aeromot-Industria Mecanico Metalurgica Ltda., Av.
das Industrias-1210, Bairro Anchieta, Caixa Postal 8031, 90200-Porto
Alegre-RS, Brazil. This information may also be examined at the Federal
Aviation Administration (FAA), Central Region, Office of the Regional
Counsel, Attention: Rules Docket No. 98-CE-27-AD, Room 1558, 601 E.
12th Street, Kansas City, Missouri 64106; or at the Office of the
Federal Register, 800 North Capitol Street, NW, suite 700, Washington,

Engineer, FAA, Atlanta Aircraft Certification Office, One Crown Center,

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 Aeromot Model
AMT-200 powered gliders was published in the Federal Register as a
notice of proposed rulemaking (NPRM) on April 30, 1998 (63 FR 23685).
The NPRM proposed to require replacing any engine oil system hose, part
number 10702, 10703, or 10704, with a hose with a larger internal
diameter, part number 10706, 10707, or 10708. Accomplishment of the
proposed action as specified in the NPRM would be in accordance with
Aeromot Service Bulletin B.S. No. 200-79-036, Issue Date: January 30,
1997.
The NPRM was the result of mandatory continuing airworthiness
information (MCAI) issued by the airworthiness authority for Brazil.
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 18 powered gliders in the U.S. registry will
be affected by this AD, that it will take approximately 7 workhours per
powered glider to accomplish the replacements, 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
$7,560, or $420 per powered glider.
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
[[Page 39232]]
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
Accordingly, pursuant to the authority delegated to me by the
Administrator, the Federal Aviation Administration amends part 39 of
the Federal Aviation Regulations (14 CFR part 39) as follows:
PART 39--AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
2. Section 39.13 is amended by adding a new airworthiness directive
(AD) to read as follows:
98-15-19 Aeromot-Industria Mecanico Metalurgica Ltda.: Amendment
39-10670; Docket No. 98-CE-27-AD.
Applicability: Model AMT-200 powered gliders, serial numbers
200.046 through 200.066, certificated in any category.
Note 1: This AD applies to each powered glider 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 powered gliders 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 (d) 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 within the next 50 hours time-in-service
(TIS) after the effective date of this AD, unless already
accomplished.
To prevent inefficiency of the engine lubricating system because
of ineffective flexible hoses, which could result in an in-flight
engine shutdown with consequent loss of powered glider
controllability, accomplish the following:
(a) For powered gliders with a serial number in the range of
200.046 through 200.058: Replace any engine oil system hose, part
number 10702, with a hose with a larger internal diameter, part
number 10706. Accomplish the replacement in accordance with Part I
of the Accomplishment Instructions of Aeromot Service Bulletin B.S.
No. 200-79-036, Issue Date: January 30, 1997.
(b) For powered gliders with a serial number in the range of
200.059 through 200.066: Replace any engine oil system hose, part
number 10702, 10703, or 10704, with a hose with a larger diameter,
part number 10706, 10707, or 10708. Accomplish the replacement in
accordance with Part II of the Accomplishment Instructions of
Aeromot Service Bulletin B.S. No. 200-79-036, Issue Date: January
30, 1997.
(c) 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 powered glider to a location
where the requirements of this AD can be accomplished.
(d) An alternative method of compliance or adjustment of the
compliance time that provides an equivalent level of safety may be
approved by the Manager, Atlanta Aircraft Certification Office
(ACO), One Crown Center, 1895 Phoenix Blvd., suite 450, Atlanta,
Georgia 30349. The request shall be forwarded through an appropriate
FAA Maintenance Inspector, who may add comments and then send it to
the Manager, Atlanta ACO.
Note 2: Information concerning the existence of approved
alternative methods of compliance with this AD, if any, may be
obtained from the Atlanta ACO.
(e) Questions or technical information related to Aeromot
Service Bulletin B.S. No. 200-79-036, Issue Date: January 30, 1997,

Date: January 30, 1997. This incorporation by reference was approved
by the Director of the Federal Register in accordance with 5 U.S.C.
