SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to add an AD that would apply 

to DG Flugzeugbau GmbH Model DG– 

1000T airplanes. The NPRM was 

published in the Federal Register on 

June 27, 2014 (79 FR 36440), and 

proposed to revise AD 2013–22–14, 

Amendment 39–17646 (78 FR 65869, 

November 4, 2013) (‘‘AD 2013–22–14’’). 

Since we issued AD 2013–22–14, the 

manufacturer of the Solo Kleinmotoren 

Model 2350 C engine has developed an 

engine modification to restore engine 

operation. 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued AD No.: 2013– 

0217R1, dated May 5, 2014 (referred to 

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

unsafe condition for the specified 

products. The MCAI states: 

An occurrence of Solo 2350 C engine shaft 

failure and consequent propeller detachment 

was reported. The preliminary investigation 

revealed that the failed shaft was earlier 

modified in accordance with an approved 

method. 

This condition, if not corrected, could lead 

to additional cases of release of the propeller 

from the engine, possibly resulting in damage 

to the sailplane, or injury to persons on the 

ground. 

To address this potential unsafe condition, 

EASA issued Emergency AD 2013–0217–E to 

prohibit operation of the engine. 

Since that AD was issued, Solo 

Kleinmotoren GmbH developed a 

modification consisting of installing an 

improved eccenter axle—pulley assembly, 

allowing to resume operation of the engine. 

For the reason described above, this AD is 

revised to incorporate the optional 

modification, cancelling the operational 

restriction. 

The MCAI can be found in the AD 

docket on the Internet at: http://

www.regulations.gov/

#!documentDetail;D=FAA-2013-0929- 

0003. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (79 

FR 36440, June 27, 2014) or on the 

determination of the cost to the public. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed except for minor editorial 

changes. We have determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (79 FR 

36440, June 27, 2014) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (79 FR 36440, 

June 27, 2014). 

Costs of Compliance 

We estimate that this AD will affect 2 

products of U.S. registry. We also 

estimate that it will take about .5 workhour per product to comply with the 

retained requirement of placing a copy 

of AD 2013–22–14 into the Limitations 

section of the aircraft flight manual, 


rmajette on DSK2TPTVN1PROD with RULES2
54896 Federal Register / Vol. 79, No. 178 / Monday, September 15, 2014 / Rules and Regulations 

which prohibits engine operation. The 

average labor rate is $85 per work-hour. 

Based on these figures, we estimate 

the cost of this retained requirement on 

U.S. operators to be $85, or $42.50 per 

product. 

In addition, we estimate that the 

optional engine modification will take 

about 1.5 work-hours and require parts 

costing $100, for a cost of $227.50. If 

both products of U.S. registry 

incorporated the engine modification, 

the cost of the modification on U.S. 

operators will be $455. 

If the engine modification is done, it 

will also take about .5 work-hour per 

product to remove the engine operation 

restriction (copy of AD 2013–22–14) 

from the Limitations section of the 

aircraft flight manual. The average labor 

rate is $85 per work-hour, for a cost of 

$42.50 per product. 

According to the manufacturer, some 

of the costs of this AD may be covered 

under warranty, thereby reducing the 

cost impact on affected individuals. We 

do not control warranty coverage for 

affected individuals. 

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 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.

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all 

Dassault Aviation Model FAN JET 

FALCON, FAN JET FALCON SERIES C, 

D, E, F, and G airplanes; Model 

MYSTERE–FALCON 200 airplanes; and 

Model MYSTERE–FALCON 20–C5, 20– 

D5, 20–E5, and 20–F5 airplanes. This 

AD was prompted by reports of a 

manufacturing defect in the charge 

indicator on fire extinguisher bottles. 

This AD requires repetitive weighing of 

fire extinguisher bottles having a certain 

part number, and eventual replacement 

of those bottles to terminate the 

repetitive weighing. We are issuing this 

AD to detect and correct a dormant 

failure in the fire suppression system, 

which could result in the inability to 

put out a fire in an engine, auxiliary 

power unit, or rear compartment. 

DATES: This AD becomes effective 

October 20, 2014. 

The Director of the Federal Register

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to all Dassault Aviation Model 

FAN JET FALCON, FAN JET FALCON 

SERIES C, D, E, F, and G airplanes; 

Model MYSTERE–FALCON 200 

airplanes; and Model MYSTERE– 

FALCON 20–C5, 20–D5, 20–E5, and 20– 

F5 airplanes. The NPRM published in 

the Federal Register on May 21, 2013 

(78 FR 29669). The NPRM was 

prompted by reports of a manufacturing 

defect in the charge indicator on fire 

extinguisher bottles. The NPRM 

proposed to require repetitive weighing 

of fire extinguisher bottles having a 

certain part number, and eventual 

replacement of those bottles to 

terminate the repetitive weighing. We 

are issuing this AD to detect and correct 

a dormant failure in the fire suppression 

system, which could result in the 

inability to put out a fire in an engine, 

auxiliary power unit, or rear 

compartment. 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2012–0189, 

dated September 24, 2012 (referred to 

after this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for all Dassault Aviation Model FAN 

JET FALCON, FAN JET FALCON 

SERIES C, D, E, F, and G airplanes; 

Model MYSTERE–FALCON 200 

airplanes; and Model MYSTERE– 

FALCON 20–C5, 20–D5, 20–E5, and 20– 

F5 airplanes. The MCAI states: 

A manufacturing defect of the charge 

indicator of fire extinguisher bottles has been 

reported on Dassault Aviation Fan Jet Falcon 

and Myste`re-Falcon 20 series aeroplanes. 

The results of the investigations concluded 

that this defect may lead to corrosion of the 

charge indicator, causing improper 

indication of loss of pressure inside the 

bottle. In addition, the Part Numbers (P/N) of 

the fire extinguishers and batch numbers of 

the affected charge indicators have been 

identified. 

This condition, if not detected and 

corrected, could constitute a dormant failure 

that might impact the capability to extinguish 

a fire, either in an engine or the Auxiliary 

Power Unit (APU) or the rear compartment, 

possibly resulting in damage to the aeroplane 

and injury to the occupants.
