Airworthiness Directives; Dassault Aviation Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to supersede an existing airworthiness directive
(AD) that applies to certain Dassault Aviation Model FALCON 7X
airplanes. The existing AD currently requires revising the Abnormal
Procedures and Limitations sections of the Dassault F7X airplane flight
manual. Since we issued that AD, we have determined that additional
actions are necessary to address the identified unsafe condition. This
proposed AD would require performing a test of the power distribution
control units (PDCU) cards and generator control units (GCU) cards to
detect faculty components, and if any faulty components are found,
replacing any affected PDCU or GCU card. We are proposing this AD to
detect and correct a leakage failure mode of transient voltage
suppression (TVS) diodes used on PDCU cards or GCU cards in the primary
power distribution boxes (PPDB), which, in combination with other
system failures, could lead to loss of controllability of the airplane.
DATES: We must receive comments on this proposed AD by April 30, 2012.

Discussion
On August 11, 2010, we issued AD 2010-18-03, Amendment 39-16416 (75
FR 51931, August 24, 2010). That AD required actions intended to
address an unsafe condition on certain Dassault Aviation Model FALCON
7X airplanes. The preamble of AD 2010-18-03 explains that we consider
the requirements of that AD ``interim action'' and are considering
further rulemaking to mandate inspection (testing) of the PDCU and GCU
cards and replacement of faulty cards, as required by European Aviation
Safety Agency AD 2010-0073, dated April 15, 2010. The planned
compliance time for those actions would allow enough time for prior
public comment on the merits of those actions. This proposed AD follows
from that determination.
The unsafe condition is a leakage failure mode of TVS diodes used
on PDCU or GCU cards in the PPDB, which, in combination with other
system failures, could lead to loss of controllability of the airplane.
You may obtain further information by examining the MCAI in the AD
docket.
Relevant Service Information
Dassault Aviation has issued Mandatory Service Bulletin 7X-133,
dated December 4, 2009. Goodrich Power Systems has issued the following
service bulletins:
Goodrich Service Bulletin 80232190-24-01, dated August 13,
2009;
Goodrich Service Bulletin 80232191-24-01, dated August 13,
2009; and
Goodrich Service Bulletin 80232192-24-01, dated August 13,
2009.
The actions described in this service information are intended to
correct the unsafe condition identified in the MCAI.
FAA's Determination and Requirements of This Proposed AD
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are proposing this AD because we
evaluated all pertinent information and determined an unsafe condition
exists and is likely to exist or develop on other products of the same
type design.
Costs of Compliance
Based on the service information, we estimate that this proposed AD
would affect about 9 products of U.S. registry.
The actions that are required by AD 2010-18-03, Amendment 39-16416
(75 FR 51931, August 24, 2010), and retained in this proposed AD, take
about 4 work-hours per product, at an average labor rate of $85 per
work hour. Based on these figures, the estimated cost of the currently
required actions is $340 per product.
We estimate that it would take about 4 work-hours per product to
comply with the new basic requirements of this proposed AD. The average
labor rate is $85 per work-hour. Based on these figures, we estimate
the cost of the proposed AD on U.S. operators to be $3,060, or $340 per
product.
We have received no definitive data that would enable us to provide
cost estimates for the on-condition actions specified in this proposed
AD. We have no way of determining the number of products that may need
these actions.
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. ``Subtitle VII: Aviation
Programs,'' describes in more detail the scope of the Agency's
authority.
We are issuing this rulemaking under the authority described in
``Subtitle VII, Part A, Subpart III, Section 44701: General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.
Regulatory Findings
We determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would not
have a substantial direct effect 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.
For the reasons discussed above, I certify this proposed
regulation:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation in Alaska, and
(4) 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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 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. The FAA amends Sec. 39.13 by removing AD 2010-18-03, Amendment
39-16416 (75 FR 51931, August 24, 2010), and adding the following new
AD:
Dassault Aviation: Docket No. FAA-2012-0265; Directorate Identifier
2010-NM-216-AD.
(a) Comments Due Date
We must receive comments by April 30, 2012.
(b) Affected ADs
This AD supersedes AD 2010-18-03, Amendment 39-16416 (75 FR
51931, August 24, 2010).
(c) Applicability
This AD applies to Dassault Aviation Model FALCON 7X airplanes,
certificated in any category, all serial numbers except those on
which Dassault Aviation Modification M724 is embodied.
[[Page 15295]]
(d) Subject
Air Transport Association (ATA) of America Code 24: Electrical
Power.
(e) Reason
This AD was prompted by a determination that additional actions
are necessary to address the identified unsafe condition identified
in AD 2010-18-03, Amendment 39-16416 (75 FR 51931, August 24, 2010).
We are issuing this AD to detect and correct a leakage failure mode
of transient voltage suppression (TVS) diodes used on power
distribution control units (PDCU) cards or generator control units
(GCU) cards in the primary power distribution boxes, which, in
combination with other system failures, could lead to loss of
controllability of the airplane.
(f) Compliance
You are responsible for having the actions required by this AD
performed within the compliance times specified, unless the actions
have already been done.
(g) Retained Airplane Flight Manual Revision (AFM)
This AFM revision is retained from AD 2010-18-03, Amendment 39-
16416 (75 FR 51931, August 24, 2010): Within 30 days after September
8, 2010 (the effective date of AD 2010-18-03, Amendment 39-16416 (75
FR 51931, August 24, 2010)), revise the Abnormal Procedures and
Limitations sections of the Dassault F7X AFM to include the
following statement. This may be done by inserting copies of this AD
into the AFM Limitations section and Abnormal Procedures section.
``Upon display of ELEC:BUS MISCONFIG TIED in Crew Alerting
