10 CFR Part 35 

RIN 3150–AI59 

Medical Use of Byproduct Material— 

Authorized User Clarification, 

Confirmation of Effective Date 

AGENCY: Nuclear Regulatory 

Commission. 

ACTION: Direct final rule: Confirmation 

of effective date. 

SUMMARY: The Nuclear Regulatory 

Commission (NRC) is confirming the 

effective date of September 28, 2009, for 

the direct final rule that was published 

in the Federal Register on July 14, 2009 

(74 FR 33901). This direct final rule 

amended the NRC’s regulations to 

clarify that individuals who do not need 

to comply with the training and 

experience requirements as described in 

the applicable regulations for the 

medical use of byproduct material (i.e., 

are ‘‘grandfathered’’) may serve as 

preceptors and work experience 

supervisors for individuals seeking 

recognition on NRC licenses for the 

same medical uses of byproduct 

material. 

DATES: The effective date of September 

28, 2009, is confirmed for this direct 

final rule. 

ADDRESSES: Documents related to this 

rulemaking, including comments 

received, may be examined at the NRC 

Public Document Room, Room O–1F23, 

11555 Rockville Pike, Rockville, MD

SUPPLEMENTARY INFORMATION: On July 

14, 2009 (74 FR 33901), the NRC 

published in the Federal Register a 

direct final rule amending its 

regulations in 10 CFR part 35 to clarify 

that individuals who do not need to 

comply with the training and 

experience requirements as described in 

the applicable regulations for the 

medical use of byproduct material (i.e., 

are ‘‘grandfathered’’) may serve as 

preceptors and work experience 

supervisors for individuals seeking 

recognition on NRC licenses for the 

same medical uses of byproduct 

material. In the direct final rule, NRC 

stated that if no significant adverse 

comments were received, the direct 

final rule would become final on 

September 28, 2009. The NRC did not 

receive any comments that warranted 

withdrawal of the direct final rule. 

Therefore, this rule will become 

effective as scheduled. 

Dated at Rockville, Maryland, this 21st day 

of August 2009. 

For the Nuclear Regulatory Commission.

14 CFR Part 23 

[Docket No. CE296; Special Conditions No. 

23–236–SC] 

Special Conditions: Cessna Aircraft 

Company, Model 525C (CJ4); Lithium 

Ion Battery Installation 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final special conditions. 

SUMMARY: These special conditions are 

issued for the Cessna Aircraft Company, 

model 525C (CJ4) airplane. This 

airplane will have a novel or unusual 

design feature(s) associated with the 

installation of lithium ion (Li-ion) 

batteries. Cessna Aircraft Company 

proposes to use a lithium-ion main 

battery on the new model 525C (CJ4) 

commuter category airplane for main 

battery applications, and is also 

considering the use of this technology in 

several other auxiliary battery 

applications in this airplane. This type 

of battery possesses certain failure, 

operational characteristics, and 

maintenance requirements that differ 

significantly from that of the nickel 

cadmium and lead acid rechargeable 

batteries currently approved in other 

normal, utility, acrobatic, and commuter 

category airplanes. The applicable 

airworthiness regulations do not contain 

adequate or appropriate safety standards 

for this design feature. These special 

conditions contain the additional safety 

standards that the Administrator 

considers necessary to establish a level 

of safety equivalent to that established 

by the existing airworthiness standards. 

DATES: Effective Date: August 19, 2009.

SUPPLEMENTARY INFORMATION: 

Background 

On August 9, 2006, Cessna Aircraft 

Company applied for an amendment to 

Type Certificate Number A1WI to 

include the new model 525C (CJ4). The 

model 525C (CJ4), which is a derivative 

of the model 525B (CJ3) currently 

approved under Type Certificate 

Number A1WI, is a commuter category, 

low-winged monoplane with ‘‘T’’ tailed 

vertical and horizontal stabilizers, 

retractable tricycle type landing gear 

and twin turbofan engines mounted on 

the aircraft fuselage. The maximum 

takeoff weight is 16,950 pounds, the 

VMO/MMO is 305 KIAS/M 0.77 and 

maximum altitude is 45,000 feet. Cessna 

Aircraft Company proposes to utilize Liion batteries for main battery 

applications, and is considering the use 

of this technology in several other 

auxiliary battery applications in this 

airplane. 

Type Certification Basis 

Under the provisions of 14 CFR part 

21, § 21.101, Cessna Aircraft Company 

must show that the model 525C (CJ4) 

meets the applicable provisions of the 

requirements incorporated by reference 

in Type Certificate No. A1W1 or 14 CFR
