Airworthiness Directives; Glasflugel 

Models H 301 ‘‘Libelle,’’ H 301B 

‘‘Libelle,’’ Standard ‘‘Libelle,’’ and 

Standard Libelle-201B Sailplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA adopts a new 

airworthiness directive (AD) for all 

Glasflugel Models H 301 ‘‘Libelle,’’ H 

301B ‘‘Libelle,’’ Standard ‘‘Libelle,’’ and 

Standard Libelle-201B sailplanes. This 

AD requires you to replace the rudder 

actuator arm (manufactured according 

to drawing No. 301–45–10) with an 

improved design rudder actuator arm 

(manufactured following drawing No. 

301–45–13). This AD results from 

mandatory continuing airworthiness 

information (MCAI) issued by the 

airworthiness authority for Germany. 

We are issuing this AD to detect and 

correct damage to the rudder actuator 

arm, which could result in failure of the 

rudder actuator arm. This failure could 

result in reduced or loss of rudder 

control. 

DATES: This AD becomes effective on 

April 12, 2007. 

As of April 12, 2007, the Director of 

the Federal Register approved the 

incorporation by reference of certain 

publications listed in the regulation.

SUPPLEMENTARY INFORMATION: 

Discussion 

On August 4, 2006, we issued a 

proposal to amend part 39 of the Federal 

Aviation Regulations (14 CFR part 39) to 

include an AD that would apply to all 

Glasflugel Models H 301 ‘‘Libelle,’’ H 

301B ‘‘Libelle,’’ Standard ‘‘Libelle,’’ and 

Standard Libelle-201B sailplanes. This 

proposal was published in the Federal 

Register as a notice of proposed 

rulemaking (NPRM) on August 11, 2006 

(71 FR 46128). The NPRM proposed to 

require you to replace the rudder 

actuator arm (manufactured according 

to drawing No. 301–45–10) with an 

improved design rudder actuator arm 

(manufactured following drawing No. 

301–45–13). 

Comments 

We provided the public the 

opportunity to participate in developing 

this AD. The following presents the 

comment received on the proposal and 

FAA’s response to the comment: 

Comment Issue: Service Documents and 

Parts Manufacturer Approval 

Jack Buster of the Modification and 

Replacement Parts Association 

(MARPA) requests the following be 

incorporated into the regulatory action: 

1. Service documents deemed essential to 

the accomplishment of this proposed action 

be incorporated by reference and published 

in the Docket Management System (DMS); 

and 

2. The issue of parts manufacturer approval 

(PMA) be addressed in the proposed action 

and that all Directorates within the FAA treat 

the issue the same per Section 1, paragraph 

(b)(10) of Executive Order 12866. 

We agree that the service documents 

are essential and should be incorporated 

by reference. However, we do not 

incorporate by reference any document 

in a proposed AD action; instead we 

incorporate by reference the document 

in the final rule. Since we are issuing 

the proposal as a final rule AD action, 

the service information referenced in 

this action will be incorporated by 

reference. 

We are currently reviewing issues 

surrounding the posting of service 

bulletins in the Department of 

Transportation’s DMS as part of the AD 

docket. Once we have thoroughly 

examined all aspects of this issue and 

have made a final determination, we 

will consider whether our current 

practice needs to be revised. 

On the PMA issue, Mr. Buster’s 

comments are timely in that the FAA is 

currently reviewing this issue as it 

applies to all products: Transport 

airplanes, commuter airplanes, general 

aviation airplanes, engines and 

propellers, rotorcraft, and appliances. 

The FAA acknowledges that there are 

different ways of addressing this issue 

to ensure that unsafe PMA parts are 

identified and addressed. Once we have 

thoroughly examined all aspects of this 

issue including input from industry and 

have made a final determination, we 

will consider developing a standardized 

approach and standardized language on 

how to address PMA parts in 

airworthiness directives. 

We have determined that to delay this 

AD action would be inappropriate since 

an unsafe condition exists and that 

replacement of certain parts must be 

done to ensure continued safety. 

Therefore, we have made no change to 

the AD in this regard. 

Conclusion 

We have carefully reviewed the 

available data and determined that air 


pwalker on PROD1PC71 with RULES
Federal Register / Vol. 72, No. 45 / Thursday, March 8, 2007 / Rules and Regulations 10347 

safety and the public interest require 

adopting the AD as proposed except for 

minor editorial corrections. We have 

determined that these are minor 

corrections: 

• Are consistent with the intent that 

was proposed in the NPRM for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM. 

Costs of Compliance 

We estimate that this AD affects 160 

airplanes in the U.S. registry. 

We estimate the following costs to do 

the replacement of the rudder actuator 

arm (manufactured according to 

drawing No. 301–45–10): 

Labor Cost Parts cost 

Total cost 

per 

airplane 

Total cost 

on U.S. 

operators 

3 work-hours × $80 per hour = $240 .................................................................................................................. $150 $390 $62,400 

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 AD. 

Regulatory Findings 

We have 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); 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 summary of the costs 

to comply with this AD (and other 

information as included in the 

Regulatory Evaluation) and placed it in 

the AD Docket. You may get a copy of 

this summary by sending a request to us 

at the address listed under ADDRESSES. 

Include ‘‘Docket No. FAA–2006–24709; 

Directorate Identifier 2006–CE–28–AD’’

in your request.

Airworthiness Directives; Airbus Model 

A319, A320, and A321 Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

Airbus Model A319, A320, and A321 

airplanes. This AD requires installing 

spacer assemblies at the attachment 

points of the YZ-latches of the cargo 

loading system in the forward and aft 

cargo compartments, as applicable. This 

AD results from tests that have shown 

that the attachment points of the YZlatches of the cargo loading system fail 

under maximum loads. We are issuing 

this AD to prevent failure of the 

attachment points of the YZ-latches, 

which could result in unrestrained 

cargo causing damage to the fire 

protection system, hydraulic system, 

electrical wiring, or other equipment 

located in the forward and aft cargo 

compartments. This damage could 

adversely affect the continued safe flight 

of the airplane. 

DATES: This AD becomes effective April 

12, 2007. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of April 12, 2007. 

ADDRESSES: You may examine the AD

(telephone (800) 647–5227) is located on 

the plaza level of the Nassif Building at 

the street address stated in the 

ADDRESSES section. 

Discussion 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to certain Airbus Model A319, 

A320, and A321 airplanes. That NPRM 

was published in the Federal Register 

on December 28, 2006 (71 FR 78105). 

That NPRM proposed to require 

installing spacer assemblies at the 

attachment points of the YZ-latches of 

the cargo loading system in the forward 

and aft cargo compartments, as 

applicable. 

Comments 

We provided the public the 

opportunity to participate in the 

development of this AD. We have 

considered the one comment received. 

The commenter, Airbus, the 

manufacturer, supports the NPRM. 

New Revision of Service Bulletin 

Since we issued the NPRM, we have 

received Revision 02 of Airbus Service 

Bulletin A320–25–1294, dated 

September 5, 2006. Revision 02 was 

issued to update the effectivity and kit 

information. We have updated the 

service bulletin reference in paragraph 

(f) of the AD to be Revision 02, and 

added Revision 01 of the service 

bulletin to paragraph (g) of the AD, 

‘‘Credit for Actions Done According to 

Previous Issues of Service Bulletin.’’

Conclusion 

We have carefully reviewed the 

available data, including the single 

comment received, and determined that 

air safety and the public interest require 

adopting the AD with the changes 

described previously. We have 

determined that these changes will 

neither increase the economic burden 

on any operator nor increase the scope 

of the AD. 

Costs of Compliance 

This AD affects about 1 airplane of 

U.S. registry. The required actions take 

about 4 work hours per airplane, at an 

average labor rate of $80 per work hour. 

Required parts cost about $2,049 per 

airplane. Based on these figures, the 

estimated cost of this AD for the U.S. 

operator is $2,369. 

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 have 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
