Airworthiness Directives; Honeywell 

International Inc. Turboshaft Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for 

Honeywell International Inc. LTS101– 

600A–2, –3, –3A, and LTS101–700D–2 

turboshaft engines with certain power 

turbine governors (PTG) model AL– 

AB1, installed, that are marked with 

compliance symbol N or P, or with no 

compliance symbol, on the PTG 

identification plate. This AD requires 

initial and repetitive replacements of 

the affected PTGs. This AD was 

prompted by reports of two accidents 

where the engines suddenly lost power 

and the helicopters had to make 

emergency autorotation landings, 

leading to substantial damage to the 

helicopters. We are issuing this AD to 

prevent loss of engine power, leading to 

emergency autorotation landing and 

damage to the helicopter. 

DATES: This AD is effective November 

29, 2011. 

We must receive comments on this 

AD by December 29, 2011.

SUPPLEMENTARY INFORMATION: 

Discussion 

We received reports of two accidents 

where the engines suddenly lost power 

and the helicopters had to make 

emergency autorotation landings. 

Investigation revealed that PTG spool 

bearings, part number (P/N) 2523973 

Revision N and P/N 2523973 Revision 

P, could fail prematurely. PTGs with 

these affected spool bearings require 

repetitive replacements before the spool 

bearings wear out prematurely. This 

condition, if not corrected, could result 

in sudden engine power loss, the 

helicopter making an emergency 

autorotation landing, and substantial 

damage to the helicopter. 

FAA’s Determination 

We are issuing this AD because we 

evaluated all the relevant information 

and determined the unsafe condition 

described previously is likely to exist or 

develop in other products of the same 

type design. 

AD Requirements 

This AD requires initial and repetitive 

replacements of PTGs model AL–AB1, 

P/N 4–301–289–03, 4–301–289–05, 4– 

301–289–09, 4–301–101–16, and 4–301– 

101–18, that are marked with 

compliance symbol N or P, or with no 

compliance symbol, on the PTG 

identification plate. 

Interim Action 

We consider this AD interim action. If 

final action is later identified, we might 

consider further rulemaking then. 

FAA’s Justification and Determination 

of the Effective Date 

An unsafe condition exists that 

requires the immediate adoption of this 

AD. The FAA has found that the risk to 

the flying public justifies waiving notice 

and comment prior to adoption of this 

rule because of the premature failure of 

the affected PTGs. Therefore, we find 

that notice and opportunity for prior 

public comment are impracticable and 

that good cause exists for making this 

amendment effective in less than 30 

days. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety and 

was not preceded by notice and an 

opportunity for public comment. 

However, we invite you to send any 

written data, views, or arguments about 

this AD. Send your comments to an 

address listed under the ADDRESSES

section. Include the docket number 

FAA–2011–1159 and Directorate 

Identifier 2011–NE–34–AD at the 

beginning of your comments. We 

mstockstill on DSK4VPTVN1PROD with RULES

Federal Register / Vol. 76, No. 219 / Monday, November 14, 2011 / Rules and Regulations 70335 

specifically invite comments on the 

overall regulatory, economic, 

environmental, and energy aspects of 

this AD. We will consider all comments 

received by the closing date and may 

amend this 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 AD. 

Costs of Compliance 

We estimate that this AD will affect 

83 Honeywell International Inc. 

LTS101–600A–2, –3, –3A, and LTS101– 

700D–2 turboshaft engines, installed on 

helicopters of U.S. registry. We also 

estimate that it will take about 3 workhours to replace a PTG on each engine. 

Required parts would cost about $3,500 

per engine. The average labor rate is $85 

per work-hour. Based on these figures, 

we estimate the total cost of this AD for 

one PTG replacement to U.S. operators, 

to be $311,665. 

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 

This AD will not have federalism 

implications under Executive Order 

13132. This AD will 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 this AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Is not a ‘‘significant rule’’ under 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979), 

(3) Will not affect intrastate aviation 

in Alaska, and 

(4) 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.
