Turboshaft and LTP101 Series 

Turboprop Engines 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

Honeywell International Inc. LTS101 

series turboshaft and LTP101 series 

turboprop engines with certain gas 

generator turbine discs installed. This 

proposed AD would require reducing 

the life limits for certain gas generator 

turbine discs. This proposed AD results 

from an error in a change to the 

engineering drawing for the gas 

generator turbine disc from which they 

manufactured 260 discs. We are 

proposing this AD to prevent rupture of 

the gas generator turbine disc, which 

could result in uncontained engine 

failure and damage to the aircraft. 

DATES: We must receive any comments 

on this proposed AD by November 24, 

2008. 

ADDRESSES: Use one of the following 

addresses to comment on this proposed 

AD.

Discussion 

Honeywell International Inc. has 

informed us that they manufactured 260 

gas generator turbine discs to an 

erroneous drawing change. Because of 

this, the gas generator turbine disc could 

rupture before reaching its published 

life limit. This condition, if not 

corrected, could result in uncontained 

engine failure and damage to the 

aircraft. 

Relevant Service Information 

We have reviewed and approved the 

technical contents of Honeywell 

International Inc. Service Bulletin (SB) 

LT 101–71–00–0002, Revision 25, dated 

August 31, 2007, that describes a 

reduced life limit and drawdown 

schedules for certain gas generator 

turbine discs and lists the serial 

numbers of those discs. 

Differences Between the Proposed AD 

and the Manufacturer’s Service 

Information 

Although the SB applies to all LTS101 

turboshaft engines and LTP101 

turboprop engines, this proposed AD 

would not apply to models LTS101– 

700D–2 and LTS101–850B–2 turboshaft 

engines because the affected discs are 

not eligible for installation on those 

engine models. We also revised the 

drawdown schedules in Table 1 of this 

proposed AD to make the grace periods 

consistent. 

FAA’s Determination and Requirements 

of the Proposed AD 

We have evaluated all pertinent 

information and identified an unsafe 

condition that is likely to exist or 

develop on other products of this same 

type design. We are proposing this AD, 

which would require removing any disc, 

part number (P/N) 4–111–015–14 that 

has a serial number (SN) listed in 

Appendix 1 of SB LT 101–71–00–0002, 

Revision 25, dated August 31, 2007, 

using the drawdown schedules 


sroberts on PROD1PC70 with PROPOSALS
Federal Register / Vol. 73, No. 187 / Thursday, September 25, 2008 / Proposed Rules 55457 

specified in Table 1 of this proposed 

AD. 

The proposed AD would require you 

to use the service information described 

previously to perform these actions. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 260 engines installed on 

aircraft of U.S. registry. We also estimate 

that it would take 1.0 work-hour per 

engine to perform the proposed actions, 

and that the average labor rate is $80 per 

work-hour. Required parts would cost 

about $8,000 per engine. Based on these 

figures, we estimate the total cost of the 

proposed AD to U.S. operators to be 

$2,100,800. 

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 have 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 that the proposed AD: 

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. Would not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this proposed AD. You may get a copy 

of this summary at the address listed 

under ADDRESSES.

SUPPLEMENTARY INFORMATION: The 

Commission’s July 21, 2008 Federal 

Register document seeks comments on 

the Rule’s costs, benefits, and 

effectiveness. The document seeks 

comments on whether the Rule should 

permit used car dealers to use a single 

bilingual Buyers Guide and, if so, on 

how to design a bilingual Buyers Guide. 

The document also asks for comments 

on the Buyers Guide’s pre-printed list of 

systems and major defects. In addition, 

the document solicits comments on 

whether the Rule should be revised to 

permit dealers to use alternative Buyers 

Guides when disclosing manufacturer’s 

warranties and other third-party 

warranties. 

On September 12, 2008, the 

Commission received a joint letter from 

Consumer Action, Consumers for Auto 

Reliability and Safety, the Consumer 

Federation of America, the National 

Association of Consumer Advocates, 

and the National Consumer Law Center 

requesting that the comment period be 

extended for sixty days. Among other 

reasons supporting the request, these 

organizations cite their need to conduct 

research to address the numerous 

questions raised in the Commission’s 

Federal Register document and changes 

that have occurred in the automotive 

marketplace and information 

technologies since the Commission last
