Airworthiness Directives; DassaultAviation Model FALCON 7X Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

AD results from mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

Following investigation of an in service 

event, it has been determined that in case a 

short circuit occurs on a weight-on-wheels 

(WOW) proximity sensor wiring, both circuit 

breakers that supply power to that wiring 

will trip, causing simultaneous de-power of 

all WOW proximity sensors of that part of the 

system. The loss of the corresponding WOW 

information would lead to untimely 

inhibition of warnings that could 

compromise the pilot capacity to react to 

abnormal or failure landing conditions. 

* * * * * 

The proposed AD would require 

actions that are intended to address the 

unsafe condition described in the MCAI. 

DATES: We must receive comments on 

this proposed AD by February 14, 2011. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2010–0031, 

dated March 3, 2010 (referred to after 

this as ‘‘the MCAI’’), to correct an unsafe 

condition for the specified products. 

The MCAI states: 

Following investigation of an in service 

event, it has been determined that in case a 

short circuit occurs on a weight-on-wheels 

(WOW) proximity sensor wiring, both circuit 

breakers that supply power to that wiring 

will trip, causing simultaneous de-power of 

all WOW proximity sensors of that part of the 

system. The loss of the corresponding WOW 

information would lead to untimely 

inhibition of warnings that could 

compromise the pilot capacity to react to 

abnormal or failure landing conditions. 

This AD requires the modification of the 

WOW System to improve its robustness 

against short circuit of the proximity sensors 

wiring by adding dedicated fuses to each 

WOW proximity sensor, in accordance with 

Dassault Aviation Service Bulletin (SB) F7X– 

065. 

You may obtain further information 

by examining the MCAI in the AD 

docket. 

Relevant Service Information 

Dassault-Aviation has issued 

Mandatory Service Bulletin 7X–065, 

dated July 24, 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.

82328 Federal Register / Vol. 75, No. 250 / Thursday, December 30, 2010 / Proposed Rules 

Differences Between This AD and the 

MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 

provided in the MCAI and related 

service information. 

We might also have proposed 

different actions in this AD from those 

in the MCAI in order to follow FAA 

policies. Any such differences are 

highlighted in a NOTE within the 

proposed AD. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 21 products of U.S. registry. 

We also estimate that it would take 

about 9 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Required 

parts would cost about $0 per product. 

Where the service information lists 

required parts costs that are covered 

under warranty, we have assumed that 

there will be no charge for these costs. 

As we do not control warranty coverage 

for affected parties, some parties may 

incur costs higher than estimated here. 

Based on these figures, we estimate the 

cost of the proposed AD on U.S. 

operators to be $16,065, or $765 per 

product. 

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); 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket.

Airworthiness Directives; Piper 

Aircraft, Inc. (Type Certificate 

Previously Held by The New Piper 

Aircraft, Inc.) Models PA–46–310P, PA– 

46–350P, and PA–46R–350T 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 Piper Aircraft, 

Inc. Models PA–46–310P and PA–46– 

350P airplanes that are equipped with a 

Lewis or Transicoil turbine inlet 

temperature (T.I.T.) gauge and 

associated probe. The existing AD 

currently requires calibrating the T.I.T. 

system; replacing any T.I.T. system that 

fails the calibration test; repetitively 

replacing the T.I.T. probe on certain 

Model PA–46–350P airplanes; and 

inserting a copy of the AD into the 

pilot’s operating handbook (POH) for 

certain airplanes. Since we issued that 

AD, the manufacturer has revised 

related service information and added 

an airplane model to the list of affected 

airplanes. This proposed AD would 

retain the actions required by AD 99– 

15–04 R1, add certain Model PA–46R– 

350T airplanes to the Applicability 

section, expand the applicability to 

include other T.I.T. systems, and 

incorporate new service information. 

We are proposing this AD to prevent 

improper engine operation caused by 

improperly calibrated T.I.T. indicators 

or defective T.I.T. probes, which could 

result in engine damage/failure with 

consequent loss of control of the 

airplane. 

DATES: We must receive comments on 

this proposed AD by February 14, 2011. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

On May 17, 2000, we issued AD 99– 

15–04 R1, Amendment 39–11747 (65 FR 

33745, May 25, 2000), for certain Piper 

Aircraft, Inc. (type certificate previously 

held by The New Piper Aircraft, Inc.) 

Models PA–46–310P and PA–46–350P 

airplanes that are equipped with a 

Lewis or Transicoil turbine inlet 

temperature (T.I.T.) gauge and 

associated probe. That AD required 

calibrating the T.I.T. system; replacing 

any T.I.T. system that fails the 

calibration test; repetitively replacing 

the T.I.T. probe on Model PA–46–350P 

airplanes; and inserting a copy of the 

AD into the Emergency Procedures 

section of the POH for certain airplanes. 

That AD resulted from field reports that 

indicated service accuracy problems 

with the existing T.I.T. system on 

certain Piper Aircraft, Inc. Models PA– 

46–310P and PA–46–350P. We issued 

that AD to prevent improper engine 

operation caused by improperly 

calibrated T.I.T. indicators or defective 

T.I.T. probes, which could result in 

engine damage/failure with consequent 

loss of control of the airplane. 

Actions Since Existing AD Was Issued 

Since we issued AD 99–15–04 R1, the 

manufacturer has revised related service 

information and has added an airplane 

model to the list of affected airplanes. 

We have also determined that the scope 

of this proposed AD goes beyond only 

airplanes equipped with Lewis or 

Transicoil gauges and/or probes.
