Note 1: The actions required by paragraph 

(g) of this AD may be done by inserting a 

copy of Bombardier TR 2A–49 and TR 2A– 

50, both dated November 17, 2009, into the 

Appendix A of Part 2 of the Bombardier CL– 

600–2B19 MRM. When these TRs have been 

included in Appendix A of Part 2 of the 

general revisions of the MRM, the general 

revisions may be inserted in the MRM, 

provided that the relevant information in the 

general revision is identical to that in 

Bombardier TR 2A–49 and TR 2A–50, both 

dated November 17, 2009. 

(1) For Task Number C36–20–133–03, the 

initial compliance time is before the 

accumulation of 15,000 total flight hours or 

within 7 months after the effective date of 

this AD, whichever occurs later. 

(2) For Task Number C30–10–133–01, the 

initial compliance time is before the 

accumulation of 15,000 total flight hours on 

the piccolo tube or within 7 months after the 

effective date of this AD, whichever occurs 

later. 

FAA AD Differences 

Note 2: This AD differs from the MCAI 

and/or service information as follows: No 

differences. 

Other FAA AD Provisions 

(h) The following provisions also apply to 

this AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, New York Aircraft 

Certification Office (ACO), ANE–170, FAA, 

has the authority to approve AMOCs for this 

AD, if requested using the procedures found 

in 14 CFR 39.19. Send information to ATTN:

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM); rescission. 

SUMMARY: We propose to rescind an 

airworthiness directive (AD) for the 

products listed above. The existing AD, 

AD 98–09–27, resulted from aircraft 

certification testing which revealed that 

stresses on the thrust reverser hinge 

were higher than had been anticipated 

during engine certification, and the 

United Kingdom Civil Aviation 

Authority, issuing AD 008–03–97. 

Since we issued AD 98–09–27, we 

discovered that its requirements were 

duplicated in airplane-level AD 2001– 

09–14, issued by the FAA Transport 

Airplane Directorate. This proposal to 

rescind the engine-level AD allows the 

public the opportunity to comment on 

the FAA’s determination of the 

duplication of requirements in another 

AD, before we rescind the engine-level 

AD. 

DATES: We must receive comments on 

this proposed AD by December 30, 

2010. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Portal: Go to 

http://www.regulations.gov, and follow 

the instructions for sending your 

comments electronically.

Discussion 

On April 23, 1998, the FAA Engine & 

Propeller Directorate issued engine AD 

98–09–27 (63 FR 24911, May 6, 1998). 

On April 30, 2001, the FAA Transport 

Airplane Directorate issued airplane AD 

2001–09–14 (66 FR 23838, May 10, 

2001). Those ADs both require the same 

initial and repetitive visual inspections 

of Rolls-Royce plc RB211–Trent 768 and 

772 series turbofan engine thrust 

reverser hinge lugs and attachment ribs 

for cracks, and, if necessary, removal 

from service and replacement with 

serviceable parts. 

Since we issued engine AD 98–09–27 

and airplane AD 2001–09–14, we 

determined that duplicate ADs to 

address the same unsafe condition were 

unnecessary. 

FAA’s Determination and Requirements 

of This Proposed AD Rescission 

We are proposing this AD rescission 

of AD 98–09–27 because we evaluated 

all information and determined that two 

FAA ADs with the same requirements 

are not necessary. 

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 determined that this proposed AD 

rescission would not have federalism 

implications under Executive Order 

13132. This proposed AD rescission 

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 this proposed rescission of a 

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 regulatory evaluation 

of the estimated costs to comply with 

this proposed AD rescission and placed 

it in the AD docket. 

List of Subjects in 14 CFR Part 39

Powered by Pratt and Whitney 4000 or 

General Electric CF6–80C2 Series 

Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Model 747–200B, –300, –400, –400D, 

and –400F series airplanes. This 

proposed AD would require an 

inspection to determine the part number 

of the door and to determine if the 

correct mid-pivot access door is 

installed, and the installation of a 

marker on the mid-pivot access door, 

and if necessary, repetitive ultrasonic 

inspections for cracking of the midpivot bolt assembly and eventual 

replacement of the mid-pivot bolt 

assembly. This proposed AD results 

from a report that the left and right 

spring beam mid-pivot bolt assembly 

access doors for the No. 1 strut were 

inadvertently installed in the incorrect 

position during strut modification. We 

are proposing this AD to detect and 

correct incorrectly installed mid-pivot 

bolt assemblies on the spring beam on 

the outboard struts. Incorrectly installed 

bolt assemblies could lead to fatigue 

cracking and consequent fracturing of 

the mid-pivot bolt assembly, which 

could lead to loss of the spring beam 

load path and the possible separation of 

a strut and engine from the airplane 

during flight. 

DATES: We must receive comments on 

this proposed AD by December 30, 

2010.
