prohibited. This AD was prompted by a 

report of an uncontrolled pitch trim 

runaway during descent. We are issuing 

this AD to prevent loss of control of the 

airplane.

contained the requirements of this 

amendment. 

We must receive comments on this 

AD by August 11, 2011.

SUPPLEMENTARY INFORMATION: 

Discussion 

On May 27, 2011, we issued 

Emergency AD 2011–12–51, which 

requires that, as of receipt of the AD, 

operation of Model FALCON 7X 

airplanes is prohibited. 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued Emergency 

Airworthiness Directive 2011–0102–E, 

dated May 26, 2011 (referred to after 

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

condition for the specified products. 

EASA has advised that a Model 

FALCON 7X airplane experienced an 

uncontrolled pitch trim runaway during 

descent. The crew succeeded in 

recovering a stable situation and 

performed an uneventful landing. 

Analysis of the Digital Flight Data 

Recorder (DFDR) and Fault History 

Database (FHDB) confirmed the event, 

but did not identify the cause of the 

pitch trim runaway. This condition, if 

not corrected, could result in loss of 

control of the airplane. 

To address this unsafe condition, the 

EASA AD prohibits, from the effective 

date of the EASA AD, any flight 

operations of FALCON 7X airplanes. 

FAA’s Determination 

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 referenced above. We are issuing 

this AD because we evaluated all 

pertinent information and determined 

the unsafe condition exists and is likely 

to exist or develop on other products of 

the same type design. 

AD Requirements 

This AD requires that, as of effective 

date of the AD, operation of Model 

FALCON 7X airplanes is prohibited. 

Interim Action 

We consider this AD interim action 

pending the outcome of the 

investigation currently being carried out 

by the manufacturer. We may consider 

further rulemaking when additional 

information is available. 

FAA’s Determination of the Effective 

Date 

An unsafe condition exists that 

requires the immediate adoption of this 

AD. The FAA has found that the risk to 

the flying public justifies waiving notice 

and comment prior to adoption of this 

rule because an uncontrolled pitch trim 

runaway during descent could result in 

loss of control of the airplane. 

Therefore, we find that notice and 

opportunity for prior public comment 

are impracticable and that good cause 

exists for making this amendment 

effective in less than 30 days. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety and 

was not preceded by notice and an 

opportunity for public comment. 

However, we invite you to send any 

written data, views, or arguments about 

this AD. Send your comments to an 

address listed under the ADDRESSES

section. Include the docket number 

FAA–2011–0477 and Directorate 

Identifier 2011–NM–108–AD at the 

beginning of your comments. We 

specifically invite comments on the 

overall regulatory, economic, 

environmental, and energy aspects of 

this AD. We will consider all comments 

received by the closing date and may 

amend this AD because of 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 AD. 

Costs of Compliance 

We estimate that this AD affects 26 

airplanes of U.S. registry. There are no 

costs associated with complying with 

this AD. 

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 

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 

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.

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This 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: 

Several reports have been received on the 

elevator power control units (PCUs) where 

the shaft (tailstock) swaged bearing liners had 

shown a higher than normal rate of wear. 

Investigation revealed that the excessive wear 

was due to the paint contamination between 

the bearing roller and bearing liner. The 

bearing paint contamination is known to be 

abrasive and could seize the bearing. 

This condition, if not corrected, could lead 

to excessive airframe vibrations and 

difficulties in aircraft pitch control. 

* * * * * 

The unsafe condition is loss of 

controllability. We are issuing this AD 

to require actions to correct the unsafe 

condition on these products. 

DATES: This AD becomes effective 

August 1, 2011. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of August 1, 2011.

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 29, 2011 (76 FR 

17362). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

Several reports have been received on the 

elevator power control units (PCUs) where 

the shaft (tailstock) swaged bearing liners had 

shown a higher than normal rate of wear. 

Investigation revealed that the excessive wear 

was due to the paint contamination between 

the bearing roller and bearing liner. The 

bearing paint contamination is known to be 

abrasive and could seize the bearing. 

This condition, if not corrected, could lead 

to excessive airframe vibrations and 

difficulties in aircraft pitch control. 

This directive mandates a free-play check 

of the shaft swaged bearing installed in the 

elevator PCU tailstock end and replacement 

of the shaft swaged bearings if excessive freeplay is found. 

The unsafe condition is loss of 

controllability. 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 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. 

Differences Between This AD and the 

MCAI or Service Information

related service information and, in
