AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Model 750 airplanes. This proposed AD 

would require an inspection to 

determine the serial numbers of the 

auxiliary power unit (APU) generator 

and the left and right engine direct 

current (DC) generators, and related 

corrective actions if necessary. This 

proposed AD would also require 

revising the airplane flight manual. This 

proposed AD results from a report of a 

DC generator overvoltage event which 

caused smoke in the cockpit and 

damage to numerous avionics and 

electrical components. We are 

proposing this AD to detect and correct 

an overvoltage condition on the DC 

electrical busses caused by exciter stator 

winding failures, and subsequent failure 

of the generator control unit (GCU) 

overvoltage protection circuitry, which 

could result in damage to critical 

electrical and avionics components. 

DATES: We must receive comments on 

this proposed AD by December 27, 

2010. 

ADDRESSES: You may send comments by 

any of the following methods:

SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this proposed AD. Send your comments 

to an address listed under the 

ADDRESSES section. Include ‘‘Docket No. 

FAA–2010–1107; Directorate Identifier 

2009–NM–263–AD’’ at the beginning of 

your comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this proposed AD. We will 

consider all comments received by the 

closing date and may amend this 

proposed 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 proposed AD. 

Discussion 

We have received a report of a DC 

generator overvoltage event which 

caused smoke in the cockpit and 

damage to numerous avionics and 

electrical components. This event 

occurred on the ground before an engine 

was started. This event was determined 

to be the result of a short in the APU 

generator windings and subsequent 

damage to the overvoltage protection 

circuit in the GCU due to prolonged 

holding of the generator reset switch in 

the cockpit. This condition, if not 

corrected, could result in an overvoltage 

condition on the DC electrical busses 

caused by exciter stator winding 

failures, and subsequent failure of the 

GCU overvoltage protection circuitry 

associated with the engine and APU DC 

generators. 

Relevant Service Information 

We have reviewed Cessna Service 

Letter SL750–24–08, dated August 13, 

2009, which describes procedures for an 

inspection to determine the serial 

number of the APU generator and the 

left and right engine 400 amp DC 

generators. For any airplane having any 

generator with a serial number from 060 

through 297 without suffix ‘‘C,’’ the 

service letter specifies to replace the 

affected generator(s) before further 

flight. We also reviewed Cessna 

Airplane Flight Manual Temporary 

Changes 75EUMA TC–R01–35, dated 

May 8, 2009; 75EUA TC–R01–35, dated 

May 8, 2009; and 75FMA TC–R01–46, 

dated April 23, 2009; which provide 

instructions not to hold the main or 

APU generator reset switches in the 

reset position for more than one second 

and to make no more than two attempts 

to reset a generator. 

FAA’s Determination and Requirements 

of This Proposed AD 

We are proposing this AD because we 

evaluated all relevant information and 

determined the unsafe condition 

described previously is likely to exist or 

develop in other products of the same 

type design. This proposed AD would 

require accomplishing the actions 

specified in the service information 

described previously. 

Interim Action 

We consider this proposed AD 

interim action. The manufacturer is 

currently developing a modification that 

will address the unsafe condition 

identified in this AD. Once this 

modification is developed, approved, 

and available, we might consider 

additional rulemaking. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 67 airplanes of U.S. 

registry. We also estimate that it would 

take up to 10 work-hours per product to 

comply with this proposed AD. The 

average labor rate is $85 per work-hour. 

Based on these figures, we estimate the 

cost of this proposed AD to the U.S. 

operators to be up to $56,950, or $850 

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), 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. 

You can find our regulatory 

evaluation and the estimated costs of 

compliance in the AD Docket.

Approval and Promulgation of OneYear Extension for Attaining the 1997 

8-Hour Ozone Standard for the New 

Jersey Portion of the PhiladelphiaWilmington-Atlantic City Moderate 

Nonattainment Area 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Proposed rule. 

SUMMARY: Under the Clean Air Act, EPA 

is proposing to approve an extension 

from June 15, 2010 to June 15, 2011 of 

the applicable attainment date for the 

New Jersey portion of the PhiladelphiaWilmington-Atlantic City 1997 8-hour 

ozone nonattainment area (Philadelphia 

Area), which is classified as moderate 

nonattainment for the 1997 8-hour 

ozone national ambient air quality 

standard (NAAQS). This proposed 

extension is based in part on complete, 

quality-assured air quality data recorded 

during the 2009 ozone season. In 

accordance with requirements for a 1- 

year extension, the Philadelphia Area’s 

4th highest daily 8-hour monitored 

ozone value during the 2009 ozone 

season at each monitor in the area is less 

than 0.084 parts per million (ppm). If 

EPA finalizes this proposed approval of 

the attainment date extension, EPA will 

revise the table with regard to the 8- 

hour ozone attainment dates for the 

New Jersey portion of the Philadelphia 

Area.
