Extension of Comment Period; 

Airplane and Engine Certification 

Requirements in Supercooled Large 

Drop, Mixed Phase, and Ice Crystal 

Icing Conditions 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM); extension of comment period. 

SUMMARY: This action extends the 

comment period for an NPRM that was 

published on June 29, 2010. In that 

document, the FAA proposed to amend 

the airworthiness standards applicable 

to certain transport category airplanes 

certified for flight in icing conditions 

and the icing airworthiness standards 

applicable to certain aircraft engines. 

The proposed regulations would 

improve safety by addressing 

supercooled large drop icing conditions 

for transport category airplanes most 

affected by these icing conditions, 

mixed phase and ice crystal conditions 

for all transport category airplanes, and 

supercooled large drop, mixed phase, 

and ice crystal icing conditions for all 

turbine engines. Bombardier Aerospace, 

an airframe manufacturer, and 

Turbomeca Groupe SAFRAN, an engine 

manufacturer, have requested an 

extension of the comment period from 

60 days to 120 days to allow time to 

adequately analyze the NPRM and 

prepare comments. 

DATES: The comment period for the 

NPRM published on June 29, 2010 (75 

FR 37311) was scheduled to close on 

August 30, 2010, and is extended until 

September 29, 2010.

Background 

On June 29, 2010, the FAA issued 

Notice No. 10–10, entitled ‘‘Airplane 

and Engine Certification Requirements 

in Supercooled Large Drop, Mixed 

Phase, and Ice Crystal Icing Conditions’’ 

(75 FR 37311, Docket No. FAA–2010– 

0636). Comments to that document were 

to be received on or before August 30, 

2010. 

By letter dated July 9, 2010, 

Bombardier Aerospace (Bombardier) 

advised that the comment period for 

NPRMs has typically been 90 days for 

proposed rule changes of far lesser 

significance and complexity. Given the 

potential impact of the rule, and the 

magnitude of the effort required to 

review it, Bombardier stated that the 

comment period should be 120 days 

instead of 60 days. By letter dated July 

26, 2010, Turbomeca Groupe SAFRAN 

(Turbomeca) also requested an 

extension to the comment period from 

60 days to 120 days, citing the same 

reasons as Bombardier. 

While the FAA concurs with 

Bombardier and Turbomeca’s 

assessments of the NPRM’s significance 

and complexity, we do not support 

extending the comment period for an 

additional 60 days. The NPRM went 

through the Aviation Rulemaking 

Advisory Committee (ARAC) process, 

which gave the aviation industry the 

opportunity to become familiar with the 

content of the NPRM. The ARAC 

working group that provided 

recommendations for the NPRM was 

comprised of members from the FAA, 

the European Aviation Safety Agency, 

and the aviation industry, including 

Bombardier. Because of the significant 

industry involvement in the rulemaking 

process for this NPRM, a 120-day 

comment period is not justified and 

would adversely impact the final 

rulemaking process. However, the FAA 

does support a 90-day comment period 

by adding an additional 30 days to the 

current comment period. A 90-day 

comment period is consistent with other 

recent rulemaking activities associated 

with aircraft icing. 

Absent unusual circumstances, the 

FAA does not anticipate any further 

extension of the comment period for 

this rulemaking. 

Extension of Comment Period 

In accordance with § 11.47(c) of Title 

14, Code of Federal Regulations, the 

FAA has reviewed Bombardier and 

Turbomeca’s petitions for extension of 

the comment period to Notice No. 10– 

10. Bombardier and Turbomeca have 

shown a substantive interest in the 

proposed rule and good cause for the 

extension. The FAA has determined that 

an extension of the comment period is 

consistent with the public interest, and 

that good cause exists for taking this 

action. 

Accordingly, the comment period for 

Notice No. 10–10 is extended until 

September 29, 2010. 

Issued in Washington, DC, on August 11, 

2010.

Proposed Amendment of Class D and 

Class E Airspace; Klamath Falls, OR 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: This action proposes to 

amend Class D and Class E airspace at 

Klamath Falls, OR. Decommissioning of 

the Merrill Non-Directional Radio 

Beacon (NDB) at Klamath Falls Airport 

has made this action necessary for the 

safety and management of Instrument 

Flight Rules (IFR) operations at the 

airport. This action also would adjust 

the geographic coordinates of the airport 

and a navigation aid, and would change 

the name of the airport. 

DATES: Comments must be received on 

or before September 30, 2010. 

ADDRESSES: Send comments on this
