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 all HPH 

s. r.o. Models 304C, 304CZ, and 304CZ– 

17 sailplanes. 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 lack of a drain hole in 

the elevator control rod, which may 

allow water to accumulate in the control 

rod and lead to possible corrosion. This 

condition could cause the elevator 

control rod to fail, which could result in 

loss of control of the sailplane. We are 

issuing this proposed AD to require 

actions to address the unsafe condition 

on these products. 

DATES: We must receive comments on 

this proposed AD by July 20, 2012. 

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 AD No.: 2012– 

0073, dated April 30, 2012 (referred to 

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

unsafe condition for the specified 

products. The MCAI states: 

A broken elevator control rod in the 

vertical fin on a Kestrel sailplane has been 

reported. 

The technical investigation revealed that 

water had soaked into the elevator control 

rod through a control bore hole and resulted 

in corrosion damage. The investigation 

concluded that the corrosion cannot be 

detected from outside the elevator control 

rod. 

This condition, if not detected and 

corrected, could lead to failure of the elevator 

control rod, possibly resulting in loss of 

control of the sailplane. 

To address this unsafe condition, HPH 

spol. s r.o. published Service Bulletins (SB): 

G304CZ–06a), G304CZ17–06a), G304C–06a), 

providing instructions for elevator control 

rod inspection and replacement. 

For the reasons described above, this AD 

requires accomplishment of a one-time 

inspection of the elevator control rod in the 

vertical fin and replacement with an 

improved control rod if control rod without 

drainage hole is used. 

You may obtain further information 

by examining the MCAI in the AD 

docket. 

Relevant Service Information 

HPH spol.s r.o. has issued Service 

Bulletin No.: G304CZ—06 a)_R01, 

G304C—06 a)_R01, G304CZ17—06 

a)_R01, dated April 23, 2012. 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. 

Costs of Compliance 

We estimate that this proposed AD 

will affect 10 products of U.S. registry. 

We also estimate that it would take 

about 6 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 $233 per 

product. 

Based on these figures, we estimate 

the cost of the proposed AD on U.S. 

operators to be $7,430, or $743 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), 

(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.

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

2. The FAA amends § 39.13 by adding 

the following new AD: 

HPH s. r.o. Sailplanes: Docket No. FAA– 

2012–0598; Directorate Identifier 2012– 

CE–017–AD. 

(a) Comments Due Date 

We must receive comments by July 20, 

2012. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to HPH s. r.o. Models

Discussion 

We issued an NPRM to amend 14 CFR 

part 39 to include an AD that would 

apply to certain The Boeing Company 

Model 757 airplanes. That NPRM 

published in the Federal Register on 

March 1, 2012 (77 FR 12506). That 

NPRM proposed to require modifying 

the fuel quantity indication system 

wiring or fuel tank systems to prevent 

development of an ignition source 

inside the center fuel tank. 

That action (77 FR 12506, March 1, 

2012) invites comments on regulatory, 

economic, environmental, and energy 

aspects of the proposal. 

That action (77 FR 12506, March 1, 

2012) was prompted by fuel system 

reviews conducted by the manufacturer. 

The actions specified by the NPRM are 

intended to prevent ignition sources 

inside the center fuel tank, which, in
