AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

Rolls-Royce Corporation (RRC) AE 

3007A1/1, AE 3007A1/3, AE 3007A1, 

AE 3007A1E, AE 3007A1P, AE 3007A3, 

AE 3007C, and AE 3007C1 turbofan 

engines with a fan spinner part number 

(P/N) 23070964 or P/N 23078783, 

installed. This proposed AD would 

require replacement of the fan spinner. 

This proposed AD results from a report 

of a fan spinner releasing from an AE 

3007A turbofan engine, during flight. 

We are proposing this AD to prevent the 

fan spinner from releasing, which could 

result in injury, damage to the engine, 

and damage to the airplane. 

DATES: We must receive any comments 

on this proposed AD by August 24, 

2009.

addresses to comment on this proposed 

AD.

Discussion 

We received a report of a fan spinner 

releasing from an AE 3007A turbofan 

engine, during flight. After observing 

noise and vibration, the flight crew shut 

down the No. 1 engine and made an 

uneventful landing. Inspection of the 

No. 1 engine revealed a missing fan 

spinner and damage to the fan blades. 

Also noted was debris penetration 

through the forward engine cowl in 

three locations, and through the 

airplane outer skin in two locations. At 

the time of inspection, the No. 1 engine 

had accumulated 11,682 operating 

hours time-since-new, and 8,535 cyclesin-service-since-new. RRC then 

performed spin pit testing of the 

affected design fan spinner, and found 

a high stress concentration in the 12 bolt 

hole windows of the fan spinner. This 

stress concentration can potentially 

develop into low-cycle-fatigue cracks. 

This condition, if not corrected, could 

result in the fan spinner releasing, 

which could result in injury, damage to 

the engine, and damage to the airplane. 

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 replacement of the 

fan spinner, P/N 23070964 or P/N 

23078783. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 1,600 RRC AE 3007A series 

and AE 3007C series turbofan engines 

installed on airplanes of U.S. registry. 

We also estimate that it would take 

about one work-hour per engine to 

perform the proposed actions, and that 

the average labor rate is $80 per workVerDate Nov<24>2008 16:32 Jun 23, 2009 Jkt 217001 PO 00000 Frm 00003 Fmt 4702 Sfmt 4702 E:\FR\FM\24JNP1.SGM 24JNP1

hour. Required parts would cost about 

$12,943 per engine. Based on these 

figures, we estimate the total cost of the 

proposed AD to U.S. operators to be 

$20,836,800. 

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.

Airworthiness Directives; General 

Electric Company CF6–50C Series 

Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to revise 

an existing airworthiness directive (AD) 

for General Electric Company (GE) CF6– 

50C series turbofan engines. That AD 

currently requires reworking certain 

forward fan stator cases and installing a 

fan module secondary containment 

shield. This proposed AD would require 

the same actions but would eliminate a 

certain service bulletin from the 

compliance method. This proposed AD 

results from a review that shows that 

only one of the service bulletins 

referenced in the original AD is 

applicable as a compliance method. We 

are proposing this AD revision to 

prevent uncontained fan blade failures, 

which can result in separation of
