AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (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: The manufacturer has 

received a report of a failed canopy 

jettison test, during a regular 

maintenance check. The investigation 

revealed that a cable shroud of the 

jettison system protruded the canopy 

structure, which probably caused the 

malfunction. Inability to jettison the 

canopy in flight would prevent 

evacuation of the aeroplane in case of 

need. 

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 April 30, 2010. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Portal: Go to 

http://www.regulations.gov. Follow the 

instructions for submitting comments.

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued AD No. 2009– 

0279, dated December 23, 2009 (referred 

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

an unsafe condition for the specified 

products. The MCAI states: 

The manufacturer has received a report of 

a failed canopy jettison test, during a regular 

maintenance check. The investigation 

revealed that a cable shroud of the jettison 

system protruded the canopy structure, 

which probably caused the malfunction. 

Inability to jettison the canopy in flight 

would prevent evacuation of the aeroplane in 

case of need. 

For the reason stated above, this AD 

mandates an additional one time canopy 

jettison test and repair if necessary. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

Grob Aircraft AG has issued Service 

Bulletin No. MSB1078–164, dated July 

21, 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 the 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 this State of 

Design Authority, they have notified us 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all 

information and determined the unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Differences Between This Proposed AD 

and the MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 


emcdonald on DSK2BSOYB1PROD with PROPOSALS-1
Federal Register / Vol. 75, No. 50 / Tuesday, March 16, 2010 / Proposed Rules 12467 

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 

We estimate that this proposed AD 

will affect 3 products of U.S. registry. 

We also estimate that it would take 

about 2 work-hours per product to 

comply with the 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 $510 or $170 per 

product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 3 work-hours and require parts 

costing $68, for a cost of $323 per 

product. 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); 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.

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all 

Quartz Mountain Aerospace, Inc. Model 

11E airplanes. This proposed AD would 

require you to clean and lubricate the 

aileron pushrod bearings. This proposed 

AD results from reports of the aileron 

control stick force increasing and of the 

controls being very noisy. We are 

proposing this AD to detect and correct 

insufficient lubrication and residual 

metallic paint particles in the pushrod 

end ball joints, which could result in 

difficulty actuating aileron controls 

sometime during flight after takeoff. 

This condition could lead to difficulty 

controlling the airplane in flight.

ADDRESSES section. Include the docket 

number, ‘‘FAA–2010–0261; Directorate 

Identifier 2010–CE–008–AD’’ at the 

beginning of your comments. We 

specifically invite comments on the 

overall regulatory, economic,

concerning this proposed AD. 

Discussion 

We have received reports of the 

aileron control stick force increasing 

and of the controls being very noisy on 

Quartz Mountain Aerospace, Inc. Model 

11E airplanes. This condition may not 

be detectable before takeoff. In one 

actual instance, the condition occurred 

during flight. The stick force increased 

after preflight inspection and after 

takeoff. The airplane was operated by a 

student pilot, who had trouble flying the 

airplane when this occurred, and the 

certified flight instructor (CFI) had to 

take control and land the airplane. 

Lubricating the rod end removed the 

condition. 

Inspection revealed the left and right 

aileron push rod forward ends at the 

bellcrank were dry due to no 

lubrication. 

Further examination of the pushrod 

end ball joint hardware by the 

manufacturer found that the ball joint 

surfaces were additionally contaminated 

with specks of metallic paint as well as 

not being lubricated. A review of 

manufacturer build procedures found 

airplane painting with the rod ends 

exposed. Production procedures were 

changed to prevent further 

contamination. 

This condition, if not corrected, could 

lead to difficulty controlling the 

airplane in flight. 

Relevant Service Information 

We have reviewed Quartz Mountain 

Aerospace Service Bulletin No. SB 09– 

02, dated May 5, 2009. 

The service information describes 

procedures for cleaning and lubricating 

the aileron pushrod bearings. 

FAA’s Determination and Requirements 

of the Proposed AD 

We are proposing this AD because we 

evaluated all information and 

determined the unsafe condition 

described previously is likely to exist or 

develop on other products of the same 

type design. This proposed AD would 

require you to clean and lubricate the 

aileron pushrod bearings. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 12 airplanes in the U.S. 

registry. 

We estimate the following costs to do 

the proposed cleaning and lubrication: 

Labor cost Parts cost Total cost per 

airplane 

Total cost on 

U.S. 

operators 

1 work-hour × $85 per hour = $85 .............................................................................................. $10 $95 $1,140
