of the Interior acknowledges to exist as 

an Indian tribe pursuant to the Federally 

Recognized Indian Tribe List Act of 

1994. Tribal participation is voluntary. 

Tribes may express interest in 

participating in the advance 

notifications and may discontinue their 

participation at any time. Currently, 27 

Tribes have expressed interest in 

receiving the advance notifications. 

Tribes meeting the criteria may receive 

advance notifications after certifying 

that the Safeguards Information 

associated with the shipments of these 

materials will be adequately protected 

by complying with the requirements in 

10 CFR 73.21 and 73.22. 

After the NRC receives this 

certification and the contact information 

for the Tribal official or Tribal official’s 

designee, the NRC will add the Tribe to 

the list of advance notification contacts 

and the Tribal reservation information 

to the interactive map of Tribal 

boundaries at http://www.nrc.gov/ 

about-nrc/state-tribal/tribal-advancenotification.html. Current contact 

information can also be accessed 

throughout the year at http://nrcstp.ornl.gov/special/designee.pdf. The 

list is published annually in the Federal 

Register on or about June 30 to reflect 

any changes in information. Licensees 

should check these sites to determine 

whether they need to provide advance 

notification when they have any 

shipments meeting the criteria in 10 

CFR 71.97 or 73.37 that will pass within 

or across a participating Tribe’s 

reservation.

SUPPLEMENTARY INFORMATION: 

Background 

On April 20, 2010, the FAA published 

Special Condition No. 23–245–SC for 

the Cirrus Design Corporation new 

model SF50. The model SF50 is a 7-seat 

(5 adults and 2 children), pressurized, 

retractable gear, carbon composite, 

airplane with one turbofan engine 

mounted partially in the upper aft 

fuselage. 

The single turbofan engine is 

mounted on the upper aft fuselage, not 

in the pilot’s line of site. Upper aft 

fuselage mounted engine installations, 

along with the need to protect such 

installed engines from fires, were not 

envisioned in the development of the 

part 23 normal category regulations. 

The model SF50 certification project 

was granted an extension on September 

19, 2011. Amendment 23–62 (76 FR 

75736), published December 2, 2011, 

incorporated Special Condition No. 23– 

245–SC. On December 11, 2012, Cirrus 

Design Corporation elected to adjust the 

model SF50 certification basis to 14 CFR 

part 23, Amendment 62. 

Reason for Withdrawal 

The FAA is withdrawing Special 

Condition No. 23–245–SC because 

Cirrus elected to revise the model SF50 

certification basis to Amendment 23–62. 

The authority citation for this Special 

Condition withdrawal is 49 U.S.C. 

106(g), 40113 and 44701; 14 CFR 21.16 

and 21.17; and 14 CFR 11.38 and 11.19. 

Conclusion 

Withdrawal of this special condition 

does not preclude the FAA from issuing 

another notice on the subject matter in 

the future or committing the agency to 

any future course of action. 

Issued in Kansas City, Missouri on June 5, 

2013.

14 CFR Part 39

Airworthiness Directives; Engine 

Alliance Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Engine Alliance GP7270 and GP7277 

turbofan engines. This AD was 

prompted by damage to the highpressure compressor (HPC) stage 7–9 

spool caused by failure of the baffle 

plate feature on affected HPC stage 6 

disks. This AD requires initial and 

repetitive borescope inspections of the 

baffle plate feature and removal from 

service of the HPC stage 6 disk if the 

plate is missing material. This AD also 

requires mandatory removal from 

service of these HPC stage 6 disks at the 

next HPC module exposure. We are 

issuing this AD to prevent failure of the 

HPC stage 7–9 spool, uncontained 

engine failure, and damage to the 

airplane. 

DATES: This AD is effective July 19, 

2013.
