Airworthiness Directives: Rolls-Royce plc RB211-535 Turbofan Engines, 48084-48085 [05-16167]

Download as PDF 48084 Federal Register / Vol. 70, No. 157 / Tuesday, August 16, 2005 / Proposed Rules handlers. While assessments impose some additional costs on handlers, the costs are minimal and uniform on all handlers. Some of the additional costs may be passed on to producers. However, these costs would be offset by the benefits derived by the operation of the marketing order. In addition, the Committee’s meeting was widely publicized throughout the California kiwifruit industry and all interested persons were invited to attend the meeting and participate in Committee deliberations on all issues. Like all Committee meetings, the June 28, 2005, meeting was a public meeting and all entities, both large and small, were able to express views on this issue. Finally, interested persons are invited to submit information on the regulatory and informational impacts of this action on small businesses. This proposed rule would impose no additional reporting or recordkeeping requirements on either small or large California kiwifruit handlers. As with all Federal marketing order programs, reports and forms are periodically reviewed to reduce information requirements and duplication by industry and public sector agencies. USDA has not identified any relevant Federal rules that duplicate, overlap, or conflict with this rule. A small business guide on complying with fruit, vegetable, and specialty crop marketing agreements and orders may be viewed at: https://www.ams.usda.gov/ fv/moab.html. Any questions about the compliance guide should be sent to Jay Guerber at the previously mentioned address in the FOR FURTHER INFORMATION CONTACT section. A 20-day comment period is provided to allow interested persons to respond to this proposed rule. Twenty days is deemed appropriate because: (1) The 2005–06 fiscal period began on August 1, 2005, and the marketing order requires that the rate of assessment for each fiscal period apply to all assessable kiwifruit handled during such fiscal period; (2) the Committee needs to have sufficient funds to pay its expenses which are incurred on a continuous basis and; (3) handlers are aware of this action which was unanimously recommended by the Committee at a public meeting and is similar to other assessment rate actions issued in past years. List of Subjects in 7 CFR Part 920 Kiwifruit, Marketing agreements, Reporting and record keeping requirements. For the reasons set forth in the preamble, 7 CFR part 920 is proposed to be amended as follows: VerDate jul<14>2003 10:09 Aug 15, 2005 Jkt 205001 Ian Dargin, Aerospace Engineer, Engine Certification Office, FAA, Engine and 1.

AGENCY: SUMMARY: The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Model A300 B4–600 and A300 B4–600R series airplanes, and all Model A300 F4–605R airplanes. The existing AD currently VerDate jul<14>2003 10:09 Aug 15, 2005 Jkt 205001 requires repetitive inspections to detect cracks of certain attachment holes, installation of new fasteners, follow-on inspections or repair if necessary, and modification of the angle fittings of fuselage frame FR47. This proposed AD would revise certain inspection thresholds and intervals. This proposed AD would also add inspections to detect cracks of additional attachment holes. This proposed AD is prompted by reports of cracks found before the inspection thresholds in the existing AD and cracks found in nearby areas not inspected by the existing AD. We are proposing this AD to prevent fatigue cracking of the forward fitting of fuselage frame FR47, which could result in reduced structural integrity of the frame. We must receive comments on this proposed AD by September 15, 2005.

Airworthiness Directives: Rolls-Royce plc RB211-535 Turbofan 
Engines

AGENCY: Federal Aviation Administration, DOT.

ACTION: Proposed rule; withdrawal.

-----------------------------------------------------------------------

SUMMARY: The FAA is withdrawing a notice of proposed rulemaking (NPRM). 
That NPRM proposed a new airworthiness directive (AD) that applies to 
certain Rolls-Royce plc (RR) models RB211-535C-37, RB211-535E4-37, 
RB211-535E4-B-37, and RB211-535E4-B-75 turbofan engines. The NPRM had 
applied to those engines with radial drive steady bearing part number 
(P/N) LK76084 installed, with fewer than 3,000 engine operating hours 
on the bearing. That proposed action would have required initial and 
repetitive visual inspections of the engine oil scavenge filter for 
evidence of radial drive steady bearing failure. If after finding 
evidence, the proposed action would have required a visual inspection 
of the radial drive steady bearing for damage and evidence of bearing 
debris. Since we issued that NPRM, RR notified us that all at-risk 
radial drive steady bearings are removed from service. RR also notified 
us that remaining bearings in service are now well over the 3,000-
engine-operating-hour threshold and are no longer at risk. Accordingly, 
we withdraw the proposed rule.

FOR FURTHER INFORMATION CONTACT: Ian Dargin, Aerospace Engineer, Engine 
Certification Office, FAA, Engine and Propeller Directorate, 12 New 
England Executive Park, Burlington, MA 01803-5299; telephone (781) 238-

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39 
with a proposed airworthiness directive (AD). The proposed AD applies 
to Rolls-Royce plc (RR) models RB211-535C-37, RB211-535E4-37, RB211-
535E4-B-37, and RB211-535E4-B-75 turbofan engines. The proposed AD 
would have applied to those engines with radial drive steady bearing, 
P/N LK76084 installed, with fewer than 3,000 engine-operating-hours on 
the bearing. We published the proposed AD in the Federal Register on 
October 9, 2003, (68 FR 58291). That proposed action would have 
required initial and repetitive visual inspections of the engine oil 
scavenge filter for evidence of radial drive steady bearing failure. If 
evidence was found, that proposed action would have required a visual 
inspection of the radial drive steady bearing for damage and evidence 
of bearing debris. That proposed action was prompted by notification 
from the Civil Aviation Authority (CAA), which is the airworthiness 
authority for the U.K. The CAA notified us that an unsafe condition may 
exist on RR models RB211-535C-37, RB211-535E4-37, RB211-535E4-B-37, and 
RB211-535E4-B-75 turbofan engines. The unsafe condition had applied to 
those engines with radial drive steady bearing P/N LK76084 installed 
with fewer than 3,000 engine operating hours on the bearing. The CAA 
received reports of seven low time failures of radial drive steady 
bearings within a four-month period. These failures were not detected 
through routine magnetic chip detector monitoring because the failed 
bronze bearing cages are nonmagnetic, and the cage failure mode is 
rapid. The proposed actions intended to prevent a possible dual-engine 
in-flight shutdown caused by radial drive steady bearing failure.
    Since the issuance of that NPRM, RR notified us that all at-risk 
radial drive steady bearings are removed from service. RR also notified 
us that the remaining bearings in service are now well over the 3,000-
engine-operating-hour threshold and are no longer at risk.
    Upon further consideration, we hereby withdraw the proposed rule 
for the following reasons:
     After RR notifying us of the removal from service and 
bearing threshold information, stated previously.

     AD 2000-09-14 (65 FR 30527, May 12, 2000) and AD 2001-19-
05 (66 FR 49099, September 26, 2001) currently address the same radial 
drive steady bearing, P/N LK76084.
     AD 2000-09-14 and AD 2001-19-05 mandate replacing low-time 
bearings that are at risk.
    Withdrawal of this notice of proposed rulemaking constitutes only 
such action, and does not preclude the agency from issuing another 
notice in the future, nor does it commit the agency to any course of 
action in the future.
    Since this action only withdraws a notice of proposed rulemaking, 
it is neither a proposed nor a final rule. Therefore, Executive Order 
12866, the Regulatory Flexibility Act, or DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979) do not cover this 
withdrawal.
