RIN 2120-AA64
Airworthiness Directives; Dornier Model 328-100 Series Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD),
applicable to certain Dornier Model 328-100 series airplanes, that
requires revising the Airplane Flight Manual (AFM) to require use of
the electrical fuel pump for take-off and landing and performance of an
operational check of the electrical fuel pump following landing. This
amendment also requires replacement of the jet booster pumps with new
or modified jet booster pumps, which terminates the requirement for the
AFM revision. 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
failure of the jet booster pumps, which could result in reduced engine
thrust during take-off or landing, and consequent increased risk of
impact with terrain.
DATES: Effective September 4, 1998.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of September 4, 1998.
ADDRESSES: The service information referenced in this AD may be
obtained from FAIRCHILD DORNIER, DORNIER

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 Dornier Model 328-100
series airplanes was published in the Federal Register on May 28, 1998
(63 FR 29144). That action proposed to require revising the Airplane
Flight Manual (AFM) to require use of the electrical fuel pump for
take-off and landing and performance of an operational check of the
electrical fuel pump following landing. That action also proposed to
require replacement of the jet booster pumps with new or modified jet
booster pumps, which would terminate the requirement for the AFM
revision.
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.
Conclusion
The FAA has determined that air safety and the public interest
require the adoption of the rule as proposed.
Cost Impact
The FAA estimates that 50 airplanes of U.S. registry will be
affected by this AD.
It will take approximately 1 work hour per airplane to accomplish
the required AFM revision, at an average labor rate of $60 per work
hour. Based on these figures, the cost impact of the AFM revision
required by this AD on U.S. operators is estimated to be $3,000, or $60
per airplane.
It will take approximately 6 work hours per airplane to accomplish
the required replacement, at an average labor rate of $60 per work
hour. Required parts will be provided by the manufacturer at no cost to
the operators. Based on these figures, the cost impact of the
replacement required by this AD on U.S. operators is estimated to be
$18,000, or $360 per airplane.
The cost impact figures discussed above are 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
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 the following new
airworthiness directive:
98-16-10 Dornier Luftfahrt GMBH: Amendment 39-10686. Docket 98-NM-
90-AD.
Applicability: Model 328-100 series airplanes, serial numbers
3005 through 3093 inclusive; 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 (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 as indicated, unless accomplished
previously.
To prevent failure of the jet booster pumps, which could result
in reduced engine thrust during take-off or landing, and consequent
increased risk of impact with terrain, accomplish the following:
(a) Within 5 days after the effective date of this AD, revise
the Limitations Section of the FAA-approved Airplane Flight Manual
(AFM) by inserting a copy of Dornier All Operators Telefax AOT-328-
28-014, Revision 1, dated October 16, 1996, into the AFM to require
use of the electrical fuel pump for take-off and landing and
performance of an operational check of the electrical fuel pump
following landing.
(b) Within 180 days after the effective date of this AD, replace
the jet booster pumps having part number (P/N) 219335-2 with new or
modified jet booster pumps, having P/N 219335-3, in accordance with
Dornier Service Bulletin SB-328-28-211, dated March 26, 1997.
Accomplishment of this replacement constitutes terminating action
for the requirements of paragraph (a) of this AD; after the
replacement has been accomplished, the previously required
limitation may be removed from the AFM.
(c) As of the effective date of this AD, no person shall install
a jet booster pump, part number 219335-2, on any airplane.
(d) 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.
[[Page 40819]]
(e) 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.
(f) The actions shall be done in accordance with Dornier All
Operators Telefax (AOT) AOT-328-28-014, Revision 1, dated October
16, 1996; and Dornier Service Bulletin SB-328-28-211, dated March
26, 1997. This incorporation by reference was approved by the
Director of the Federal Register in accordance with 5 U.S.C. 552(a)

Note 3: The subject of this AD is addressed in German
airworthiness directives 97-004, dated January 30, 1997; and 97-149,
dated May 22, 1997.
(g) This amendment becomes effective on September 4, 1998.
