Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule; request for 

comments. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for General 

Electric Company (GE) CF34–10E series 

turbofan engines. This AD requires 

removing the main fuel pump (MFP) 

inlet strainer from certain MFPs, 

installing a certain replacement flange 

as an interim repair, and performing 

initial and repetitive visual inspections 

of the main fuel filter. This AD results 

from three reports of release of the 

tripod support legs on the MFP inlet 

strainer, leading to engine in-flight 

shutdown. We are issuing this AD to 

prevent engine in-flight shutdown due 

to MFP malfunctions. 

DATES: This AD becomes effective 

October 16, 2006. The Director of the 

Federal Register approved the 

incorporation by reference of certain 

publications listed in the regulations as 

of October 16, 2006. 

We must receive any comments on 

this AD by November 28, 2006.

SUPPLEMENTARY INFORMATION: In August 

2006, we became aware of one report, 

and in September 2006, two reports of 

cracking and release of the tripod 

support legs on the MFP inlet strainer, 

leading to engine in-flight shutdown, on 

GE CF34–10E series turbofan engines. 

When the tripod support legs release, 

they travel downstream and impact 

against the MFP gear assembly. This 

causes the MFP to jam, interrupting fuel 

flow, which leads to engine flameout. 

Investigations are ongoing, and our 

preliminary determination is that the 

cause of failure is a manufacturing 

quality control problem with the MFP 

inlet strainers. Current field data shows 

that the failures are an infant mortality 

type of failure. This AD requires 

removing the low-time strainers first. 

This condition, if not corrected, could 

result in an engine in-flight shutdown 

due to MFP malfunctions. 

Relevant Service Information 

We have reviewed and approved the 

technical contents of GE Alert Service 

Bulletin (ASB) No. CF34–10E S/B 73–

A0011, dated September 15, 2006. That 

ASB describes procedures for removing 

the MFP inlet strainer, installing a 

certain replacement flange as an interim 

repair, and initial and repetitive visual 

inspections of the main fuel filter. 

FAA’s Determination and Requirements 

of This AD 

The unsafe condition described 

previously is likely to exist or develop 

on other GE CF34–10E series turbofan 

engines of the same type design. For 

that reason, we are issuing this AD to 

prevent engine in-flight shutdown due 

to MFP malfunctions. This AD requires: 

• Within 40 engine flight hours after 

the effective date of this AD, removing 

the MFP inlet strainer from the affected 

MFPs listed by serial number in GE ASB 

No. CF34–10E S/B 73–A0011, dated 

September 15, 2006; and 

• Within 150 engine flight hours after 

the effective date of this AD, removing 

all other MFP inlet strainers; and 

• Installing a certain replacement 

flange in all MFPs as an interim repair; 

and 

• Remarking the MFP part number 

from 2043M12P03 to 2043M12P04; and 

• Performing initial and repetitive 

visual inspections of the main fuel filter. 

You must use the service information 

described previously to perform the 

actions required by this AD. 

FAA’s Determination of the Effective 

Date 

Since an unsafe condition exists that 

requires the immediate adoption of this 

AD, we have found that notice and 

opportunity for public comment before 

issuing this AD are impracticable, and 

that good cause exists for making this 

amendment effective in less than 30 

days. 

Interim Action 

These actions are interim actions and 

we may take further rulemaking actions 

in the future. 

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 us any 

written relevant data, views, or 

arguments regarding this AD. Send your

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 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 the regulation: 

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. 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. 

We prepared a summary of the costs 

to comply with this AD and placed it in 

the AD Docket. You may get a copy of 

this summary at the address listed 

under ADDRESSES.

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Air Tractor, Inc. (Air Tractor) Models 

AT–802 and AT–802A airplanes. This 

AD requires you to repetitively inspect 

the attach angles on the firewall 

mounted hopper rinse tank shelf for 

damage and/or cracks and replace 

damaged and/or cracked attach angles 

with steel attach angles. Replacing the 

attach angles with steel attach angles 

terminates the repetitive inspection 

requirement. Reports of an 

uncommanded change in the engine 

power setting caused by separation of 

the hopper rinse tank shelf from the 

firewall prompted this AD. We are 

issuing this AD to detect and correct 

damage and/or cracks in the attach 

angles on the firewall mounted hopper 

rinse tank shelf, which could result in 

failure of the attach angles. This failure 

could lead to shelf movement under 

maneuver load and shifting of the 

engine power cables, which could result 

in an uncommanded engine power 

setting change. 

DATES: This AD becomes effective on 

November 3, 2006. 

As of November 3, 2006, the Director 

of the Federal Register approved the 

incorporation by reference of certain 

publications listed in the regulation.

SUPPLEMENTARY INFORMATION: 

Discussion 

On June 13, 2006, we issued a 

proposal to amend part 39 of the Federal 

Aviation Regulations (14 CFR part 39) to 

include an AD that would apply to 

certain Air Tractor Models AT–802 and 

AT–802A airplanes. This proposal was 

published in the Federal Register as a 

notice of proposed rulemaking (NPRM) 

on June 20, 2006 (71 FR 35398). The 

NPRM proposed to require you to 

repetitively inspect the attach angles on 

the firewall mounted hopper rinse tank 

shelf for damage and/or cracks and 

replace damaged and/or cracked attach 

angles. Replacing the attach angles with 

steel attach angles, part number 60568–

3, would terminate the proposed 

repetitive inspection requirement. 

Comments 

We provided the public the 

opportunity to participate in developing 

this AD. We received one comment from 

Carroll Communications. The comment 

is in reference to wind turbine radar 

interference. 

We determined the comment is not 

relevant to this AD. We are not changing 

the final rule AD action based on the 

comment. 

Conclusion 

We have carefully reviewed the 

available data and determined that air 

safety and the public interest require 

adopting the AD as proposed except for 

minor editorial corrections. We have 

determined that these minor 

corrections: 

• Are consistent with the intent that 

was proposed in the NPRM for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM. 

Costs of Compliance 

We estimate that this AD affects 219 

airplanes in the U.S. registry. 

We estimate the following costs to do 

the inspection: 

Labor cost Parts cost Total cost per 

airplane 

Total cost on U.S. 

operators 

1 work-hour × $80 an hour = $80 ....................... Not applicable ...................................................... $80 $80 × 219 = $17,520. 

We estimate the following costs to do 

any necessary replacements that will be 

required based on the results of the 

inspection. We have no way of 

determining the number of airplanes 

that may need this replacement: 

Labor cost Parts cost Total cost for each airplane 

3 work-hours × $80 an hour = $240 ............................................................................................ $105 $240 + $105 = $345. 

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 AD.
