Airworthiness Directives; Avions Pierre Robin Model R2160
Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: This document proposes to adopt a new airworthiness directive
(AD) that would apply to certain Avions Pierre Robin Model R2160
airplanes. The proposed AD would require inspecting to assure that the
fuel filler cap has a 2.5 millimeter (mm) diameter hole drilled through
it or that a vinyl piping is connected to the filler neck inside the
cabin. If neither of these items exists, the proposed AD would require
replacing the fuel filler cap with a fuel filler cap that has a 2.5 mm
diameter hole drilled through it. The proposed AD is the result of
mandatory continuing airworthiness information (MCAI) issued by the
airworthiness authority for France. The actions specified in this
proposed AD are intended to detect and correct the installation of
improperly designed fuel venting system parts, which could result in an
inadequate fuel supply to the engine with loss of engine power.
DATES: Comments must be received on or before March 26, 1999.
ADDRESSES: Submit comments in triplicate to the Federal Aviation
Administration (FAA), Central Region, Office of the Regional Counsel,
Attention: Rules Docket No. 98-CE-81-AD, Room 1558, 601 E. 12th Street,
Kansas City, Missouri 64106. Comments may be inspected at this location

City, Missouri 64106.
Discussion
The Direction Generale de l'Aviation Civile (DGAC), which is the
airworthiness authority for France, notified the FAA that an unsafe
condition may exist on certain Avions Pierre Robin Model R2160
airplanes. The DGAC reports that deformation of the fuel tank could
result if one of the following does not exist:
--The fuel filler cap has a 2.5 millimeter (mm) diameter hole drilled
through it; or
--A vinyl piping is connected to the filler neck inside the cabin.
This condition, if not corrected, could result in an inadequate
fuel supply to the engine with loss of engine power.
Relevant Service Information
Avions Pierre Robin has issued Service Bulletin No. 135, dated May
17, 1994, which specifies procedures for inspecting the fuel tank
filler cap for proper ventilation; and specifies replacing the fuel
filler cap with a fuel filler cap that has a 2.5 mm diameter hole
drilled through it, part number (P/N) 52.23.07.010 (or FAA-approved
equivalent P/N).
The DGAC classified this service bulletin as mandatory and issued
French AD 94-130(A), dated June 8, 1994, in order to assure the
continued airworthiness of these airplanes in France.
The FAA's Determination
This airplane model is manufactured in France and is type
certificated for operation in the United States under the provisions of
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and
the applicable bilateral airworthiness agreement. Pursuant to this
bilateral airworthiness agreement, the DGAC has kept the FAA informed
of the situation described above.
The FAA has examined the findings of the DGAC; reviewed all
available information, including the service information referenced
above; and determined that AD action is necessary for products of this
type design that are certificated for operation in the United States.
Explanation of the Provisions of the Proposed AD
Since an unsafe condition has been identified that is likely to
exist or develop in other Avions Pierre Robin Model R2160 airplanes of
the same type design registered in the United States, the FAA is
proposing AD action. The proposed AD would require inspecting to assure
that the fuel filler cap has a 2.5 millimeter (mm) diameter hole
drilled through it or that a vinyl piping is connected to the filler
neck inside the cabin. If neither of these items exists, the proposed
AD would require replacing the fuel filler cap with a fuel filler cap
that has the hole drilled through it, P/N 52.23.07.010 (or FAA-approved
equivalent P/N).
Accomplishment of the proposed inspections would be required in
accordance with Avions Pierre Robin Service Bulletin No. 135, dated May
17, 1994. The proposed replacement (if necessary) would be required in
accordance with the applicable maintenance manual.
Cost Impact
The FAA estimates that 10 airplanes in the U.S. registry would be
affected by the proposed AD, that it would take approximately 1
workhour per airplane to accomplish both the proposed inspections and
replacement (if necessary), and that the average labor rate is
approximately $60 per work hour. Parts (if necessary) cost
approximately $60 per airplane. Based on these figures, the total cost
impact of the proposed AD on U.S. operators is estimated to be $1,200,
or $120 per airplane.
Regulatory Impact
The regulations proposed herein would 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
proposal would 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) if promulgated,
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 draft regulatory evaluation
prepared for this action has been placed in the Rules Docket. A copy of
it may be obtained by contacting the Rules Docket at the location
provided under the caption ADDRESSES.

The Proposed Amendment
Accordingly, pursuant to the authority delegated to me by the
Administrator, the Federal Aviation Administration proposes to amend
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:
Avions Pierre Robin: Docket No. 98-CE-81-AD.
Applicability: Model R2160 airplanes, all serial numbers up to
and including serial number 249, certificated in any category.
[[Page 10116]]
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 in the body of this AD, unless
already accomplished.
To detect and correct the installation of improperly designed
fuel venting system parts, which could result in an inadequate fuel
supply to the engine with loss of engine power, accomplish the
following:
(a) Within the next 50 hours time-in-service (TIS) after the
effective date of this AD, inspect to assure that the fuel filler
cap has a 2.5 millimeter (mm) diameter hole drilled through it or
that a vinyl piping is connected to the filler neck inside the
cabin. Accomplish this inspection in accordance with Avions Pierre
Robin Service Bulletin No. 135, dated May 17, 1994.
(b) If neither of the conditions specified in paragraph (a) of
this AD exists, prior to further flight, replace the fuel filler cap
with a fuel filler cap that has a 2.5 mm diameter hole drilled
through it, part number (P/N) 52.23.07.010 (or FAA-approved
equivalent P/N). Accomplish this replacement in accordance with the
applicable maintenance manual.
(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 airplane to a location where
the requirements of this AD can be accomplished.
(d) An alternative method of compliance or adjustment of the
compliance times that provides an equivalent level of safety may be
used if approved by the Manager, Small Airplane Directorate, FAA,
1201 Walnut, suite 900, Kansas City, Missouri 64106. 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.
Note 2: Information concerning the existence of approved
alternative methods of compliance with this AD, if any, may be
obtained from the Small Airplane Directorate.
