14 CFR Part 39

[Docket No. FAA-2012-0265; Directorate Identifier 2010-NM-216-AD; 
Amendment 39-17098; AD 2012-12-18]
RIN 2120-AA64


Airworthiness Directives; Dassault Aviation Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are superseding an existing airworthiness directive (AD) 
for certain Dassault Aviation Model FALCON 7X airplanes. That AD 
currently requires revising the Abnormal Procedures and Limitations 
sections of the Dassault F7X Airplane Flight Manual. This new AD 
requires a test of the power distribution control units (PDCU) cards 
and generator control units (GCU) cards to detect faulty components, 
and if any faulty components are found, replacing any affected PDCU or 
GCU card. This AD was prompted by a determination that additional 
actions are necessary to address the identified unsafe condition. We 
are issuing 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: This AD becomes effective July 30, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of July 30, 2012.

ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov or in person at the U.S. Department of 
Transportation, Docket Operations, M-30, West Building Ground Floor, 
Room W12-140, 1200 New Jersey Avenue SE., Washington, DC.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM was published in the Federal Register on March 15, 2012 (77 
FR 15293), and proposed to supersede AD AD 2010-18-03, Amendment 39-
16416 (75 FR 51931, August 24, 2010).
    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,

[[Page 37796]]

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.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (77 FR 15293, March 15, 
2012) or on the determination of the cost to the public.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD as proposed.

Costs of Compliance

    We estimate that this AD will 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 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 this 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 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 AD will not have federalism implications 
under Executive Order 13132. This AD will 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 that this AD:
    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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains the NPRM (75 FR 51931, August 24, 
2010), the regulatory evaluation, any comments received, and other 
information. The street address for the Docket Operations office 
(telephone (800) 647-5527) is in the ADDRESSES section. Comments will 
be available in the AD docket shortly after receipt.

2. The FAA amends Sec.  39.13 by removing airworthiness AD 2010-18-03, 
Amendment 39-16416 (75 FR 51931, August 24, 2010), and adding the 
following new AD:

2012-12-18 Dassault Aviation: Amendment 39-17098. Docket No. FAA-
2012-0265; Directorate Identifier 2010-NM-216-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective July 30, 
2012.

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.

performed within the compliance times specified, unless the actions 
have already been done.

(g) Retained Airplane Flight Manual (AFM) Revision

    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, 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 System 
(Abnormal procedure 3-190-20), land atnearest suitable airport

15), set off the pump and if the backup pump is still rotating 
(green) in hydraulic synoptic, descend to a safe altitude or below 
15,000 ft
Caution: These temporary amendments take precedence over the same 
procedures displayed through the Electronic Check List (ECL) in the 
aeroplane.

    Note 1 to paragraph (g) of this AD: When a statement identical 
to that in paragraph (g) of this AD has been included in the 
Limitations section and Abnormal Procedures section in the general 
revisions of the AFM, the general revisions may be inserted into the 
AFM, and the copy of this AD may be removed.
