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. 

ADDRESSES: You may send comments by 

any of the following methods:

2010–NM–216–AD’’ at the beginning of 

your comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this proposed AD. We will 

consider all comments received by the 

closing date and may amend this 

proposed AD based on those comments. 

We will post all comments we 

receive, without change, to http:// 

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this proposed AD. 

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.
