Instructions of RR Alert Service Bulletin 

(ASB) RB.211–72–AE362, dated May 7, 

2004, and the inspection schedule in 

Table 1 of this AD, perform an initial 

borescope inspection of the high 

pressure-and-intermediate pressure 

(HP–IP) turbine internal and external oil 

vent tubes for coking and carbon 

buildup as follows: 

(1) Insert an 8 mm diameter flex 

borescope to see if it will pass along the 

full length of the vent tube into the 

bearing chamber. 

(2) If the vent tube prevents an 8 mm 

diameter flex borescope from passing 

along the full length of the tube into the 

bearing chamber, repeat the action using 

a 6 mm flex borescope. 

(3) If the 6 mm diameter flex 

borescope passes through to the bearing 

chamber, continue using the engine in 

service, and perform the repetitive 

inspections in this AD at the required 

intervals specified in Table 2 of this AD. 

(4) If the vent tube prevents the 6 mm 

diameter flex borescope from passing 

along the full length of the tube into the 

bearing chamber, remove the engine 

from service within 10 cycles-since-last 

inspection (CSLI).

TABLE 1.—INITIAL INSPECTION SCHEDULE

If the engine or the 05 module: Then initially inspect: 

Has reached the threshold life of 15,000 hours time-since new (TSN) 

or reached the threshold life of 3,000 cycles-since-new (CSN) on the 

effective date of this AD.

Within 1,000 hours time-in-service (TIS) or 200 cycles-in service (CIS) 

after the effective date of this AD, whichever occurs first.

inspection schedule in Table 2 of this 

AD, perform repetitive borescope 

inspections of the HP–IP turbine 

internal and external oil vent tubes for 

coking and carbon buildup.

TABLE 2.—REPETITIVE INSPECTION SCHEDULE

If at the previous inspection, before any cleaning was performed: Then: 

(1) There was no coking and carbon buildup of a visible thickness; or 

an 8 mm diameter flex borescope could pass along the full length of 

the internal vent tube into the bearing chamber.

Reinspect within 6,000 hours time-since-last-inspection (TSLI) or within 

1,200 cycles-since-last-inspection (CSLI), whichever occurs first. 

(2) The coking or carbon buildup prevented an 8 mm diameter flex 

borescope from passing through the internal vent tube, but a 6 mm 

diameter flex borescope could pass along the full length of the internal vent tube into the bearing chamber.

Reinspect within 1,500 hours TSLI or within 300 CSLI, whichever occurs first. 

(3) The coking or carbon buildup prevented the 6 mm diameter flex 

borescope from passing through the full length of the internal vent 

tube and into the bearing chamber.

Remove the engine from service within 10 CSLI.

The Proposal 

The FAA is considering an 

amendment to 14 CFR part 71 to 

establish Class E airspace at McGregor, 

MN, for McGregor/Isedor Iverson 

Airport. Controlled airspace extending 

upward from 700 feet or more above the 

surface of the earth is needed to contain 

aircraft executing instrument approach 

procedures. The area would be depicted 

on appropriate aeronautical charts. 

Class E airspace areas extending upward 

from 700 feet or more above the surface 

of the earth are published in paragraph 

6005 of FAA Order 7400.9M dated 

August 30, 2004, and effective 

September 16, 2004, which is 

incorporated by reference in 14 CFR 

71.1. The Class E designation listed in 

this document would be published 

subsequently in the Order. 

The FAA has determined that this 

proposed regulation only involves an 

establishment body of technical 

regulations for which frequent and 

routine amendments are necessary to 

keep them operationally current. 

Therefore this, proposed regulation—(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 proposed rule will 

not have a significant economic impact 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act.

The Proposed Amendment 

Accordingly, pursuant to the 

authority delegated to me, the Federal 

Aviation Administration proposes to

1963 Comp., p. 389.

§ 71.1 [Amended]

2. The incorporation by reference in 

14 CFR 71.1 of the Federal Aviation 

Administration Order 7400.9M,
