TABLE 1—ADDITIONAL BORESCOPE

INSPECTION CRITERIA—Continued 

If the engine has 

experienced: 

Then borescope 

inspect: 

(2) A shift in the 

smoothed EGT 

trending data that 

exceeds 18° F (10° 

C), but is less than 

or equal to 36° F 

(20° C).

Within 10 cycles. 

(3) A shift in the 

smoothed EGT 

trending data that 

exceeds 36° F (20° 

C).

Before further flight. 

(4) A flightcrew reported vibration determined to be 

caused by the highpressure rotor (N2).

Within 10 cycles from 

the report. 

Actions Required for Engines With Damaged 

HPT Rotor Blades 

(i) Remove the engine before further flight 

if the engine fails the borescope inspection in 

paragraph (f), (g), or (h) of this AD. 

(j) Before returning the engine to service, 

fluorescent penetrant inspect the inner 

diameter surface forward cone body (forward 

spacer arm) of the LPT rotor stage 3 disk. If 

a crack is found or if a circumferential band 

of fluorescence appears, permanently remove 

the disk from service. 

EGT System Checks 

(k) Inspect the turbine midframe (TMF) 

liner for clocking and subsequent damage to 

the EGT probes, within 50 cycles from the 

effective date of this AD or before 

accumulating 750 CSLI of the TMF liner for 

clocking, whichever occurs later. You can 

find further guidance about TMF liner 

inspections in Table 2 of this AD. 

(l) Thereafter, inspect the TMF liner for 

clocking and subsequent damage to the EGT 

probes within every 750 CSLI. You can find 

further guidance about TMF liner inspections 

in Table 2 of this AD. 

(m) If the engine shows TMF liner clocking 

resulting in wear through 100% of the wall 

thickness of the thermocouple guide sleeve, 

remove the engine and repair the TMF and 

any damage to the EGT probes before further 

flight. You can find further guidance about 

TMF liner inspections in Table 2 of this AD. 

(n) Check the resistance of the EGT system 

within 50 cycles from the effective date of 

this AD or before accumulating 750 cyclessince-the-last-resistance check of the EGT 

system, whichever occurs later. You can find 

further guidance about the EGT resistance 

check in Table 2 of this AD. 

(o) Thereafter, check the resistance of the 

EGT system within every 750 CSLI. You can 

find further guidance about EGT resistance 

checks in Table 2 of this AD. 

(p) Repair or replace any EGT system 

component that fails this check, before 

further flight. You can find further guidance 

about the EGT resistance check in Table 2 of 

this AD. 

Definitions 

(q) For the purposes of this AD, an EGT 

above redline is a confirmed over 

temperature indication that is not a result of 

EGT system error. You can find further 

guidance about troubleshooting EGT above 

redline in Table 2 of this AD. 

(r) For the purposes of this AD, a shift in 

the smoothed EGT trending data is a shift in 

a rolling average of EGT that can be 

confirmed by a corresponding shift in the 

trending of fuel flow or fan speed/core speed 

relationship. You can find further guidance 

about evaluating EGT trend data in GE 

Company Service Rep Tip 373 ‘‘Guidelines 

For Parameter Trend Monitoring.’’

SUPPLEMENTARY INFORMATION: 

History 

On Thursday September 3, 2009, the 

FAA amended Title 14 Code of Federal 

Regulations (14 CFR) part 71, to 

establish Class E airspace upward from 

700 ft. above the surface and from 1,200 

ft. above the surface at two privately 

owned heliport facilities at Oooguruk, 

AK (74 FR 45554). The two heliports 

were named ‘‘Oooguruk Drill Site 

Helipad’’ and ‘‘Oooguruk Tie-in 

Helipad’’. Subsequent to publication, the 

FAA gained further knowledge that the 

two heliports are actually named 

‘‘Pioneer Heliport’’ and ‘‘Oooguruk 

Island Heliport’’ and should be 

associated with the town of Nuiqsut (the 

closest nearby). This administrative 

action is being taken without public 

comment as it is a simple administrative 

change only, and will not affect the 

defined controlled airspace other than 

by name change and minor edit to 

unnecessary exclusion wording. The 

airspace exclusion currently associated 

with Restricted Area 2204 is 

unnecessary. Class E and Restricted 

airspace are mutually exclusive, so the 

exclusion wording is being removed. 

Class E controlled airspace extending 

upward from 700 ft. and 1,200 ft. above 

the surface in the Pioneer and Oooguruk 

Island Heliport areas are removed and 

established by this action. 

The Class E airspace areas designated 

as 700/1,200 ft. transition areas are 

published in paragraph 6005 of FAA 

Order 7400.9T, Airspace Designations 

and Reporting Points, signed August 27, 

2009, and effective September 15, 2009, 

which is incorporated by reference in 14 

CFR 71.1. The Class E airspace 

designations listed in this document 

will be published subsequently in the 

Order. 

The Rule 

This amendment to 14 CFR part 71 

establishes Class E airspace extending 

700 and 1,200 feet above the surface at 

Pioneer and Oooguruk Island Heliports, 

AK. 

The FAA has determined that this 

regulation only involves an established 

body of technical regulations for which 

frequent and routine amendments are 

necessary to keep them operationally 

current. It, therefore—(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); and (3) does not 

warrant preparation of a regulatory 

evaluation as the anticipated impact is 

so minimal. Since this is a routine 

matter that will only affect air traffic 

procedures and air navigation, it is 

certified that this rule will not have a 

significant economic impact on a 

substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act. 

The FAA’s authority to issue rules 

regarding aviation safety is found in 

Title 49 of the United States Code. 

Subtitle 1, Section 106 describes the 

authority of the FAA Administrator. 

Subtitle VII, Aviation Programs, 

describes in more detail the scope of the 

agency’s authority. 

This rulemaking is promulgated 

under the authority described in 

Subtitle VII, Part A, Subpart 1, Section 

40103, Sovereignty and use of airspace. 

Under that section, the FAA is charged 

with prescribing regulations to ensure 

the safe and efficient use of the 

navigable airspace. This regulation is 

within the scope of that authority 

because it creates Class E airspace 

sufficient in size to contain aircraft 

executing instrument procedures for the 

two heliports at Pioneer Heliport, AK, 

and Oooguruk Island Heliport, AK, and 

represents the FAA’s continuing effort 

to safely and efficiently use the 

navigable airspace.

Adoption of the Amendment 

In consideration of the foregoing, the 

Federal Aviation Administration

14 CFR 71.1 of Federal Aviation 

Administration Order 7400.9T, Airspace 

Designations and Reporting Points, 

signed August 27, 2009, and effective 

September 15, 2009, is amended as 

follows:
