Airworthiness Directives; Boeing Model 767-300 and -300F Series Airplanes
The FAA withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD) for certain Boeing Model 767-300 and -300F series airplanes. The proposed AD would have required a one- time operational test of the pilots' seat locks and the seat tracks to ensure that the seats lock in position and the seat tracks are aligned correctly; and re-alignment of the seat tracks, if necessary. Since the proposed AD was issued, we have received new data that the affected airplanes are included in the applicability of an existing AD that addresses the unsafe condition. Accordingly, the proposed AD is withdrawn.
Airworthiness Directives; General Electric Company CF6 Series Turbofan Engines
The FAA proposes to supersede an existing airworthiness directive (AD) for General Electric Company (GE) CF6-45/-50 series turbofan engines. That AD currently requires an initial and repetitive on-wing visual inspection of the side links of the five-link forward mount assembly for cracks, and replacement of the side links and pylon attachment bolts and inspection of the fail-safe bolt and platform lug if the side links are cracked. That AD also requires a shop-level refurbishment of the side links as a terminating action to the on-wing inspection program. This proposed AD would require inspecting and refurbishing the side link at every exposure of the side link. This proposed AD would also require the same actions on certain part number side links installed on CF6-80A turbofan engines. This proposed AD results from a report of a cracked side link. We are proposing this AD to prevent failure of the side links and possible engine separation from the airplane.
Airworthiness Directives; Pratt & Whitney JT8D Series Turbofan Engines
The FAA is superseding an existing airworthiness directive (AD) for Pratt & Whitney (PW) JT8D-1, -1A, -1B, -7, -7A, -7B, -9, -9A, -11, -15, -15A, -17, -17A, -17R, and -17AR series turbofan engines. That AD currently requires revisions to the engine manufacturer's time limits section (TLS) to include enhanced inspection of selected critical life- limited parts at each piece-part opportunity. This AD modifies the airworthiness limitations section of the manufacturer's manual and an air carrier's approved continuous airworthiness maintenance program to add an eddy current inspection. An FAA study of in-service events involving uncontained failures of critical rotating engine parts has indicated the need for mandatory inspections. The mandatory inspections are needed to identify those critical rotating parts with conditions, which if allowed to continue in service, could result in uncontained failures. We are issuing this AD to prevent critical life-limited rotating engine part failure, which could result in an uncontained engine failure and damage to the airplane.
Petitions for Exemption; Dispositions of Petitions Issued
Pursuant to FAA's rulemaking provisions governing the application, processing, and disposition of petitions for exemption, part 11 of Title 14, Code of Federal Regulations (14 CFR), this notice contains the disposition of certain petitions previously received. The purpose of this notice is to improve the public's awareness of, and participation in, this aspect of FAA's regulatory activities. Neither publication of this notice nor the inclusion or omission of information in the summary is intended to affect the legal status of any petition or its final disposition.
Public Notice for a Change in Use of Aeronautical Property at Cincinnati/Northern Kentucky International Airport, Hebron, KY
Under the provisions of title 49, U.S.C. Section 47153(c), the Federal Aviation Administration is requesting public comment on the Kenton County Airport Board's request to trade a portion (1.5 acres) of airport property to V.H. Florence, LLC for a portion (1.5 acres) of V.H. Florence, LLC property effectively changing the airport portion from aeronautical use to non-aeronautical use and changing the V.H. Florence, LLC from non-aeronautical use to an aeronautical use. The property is to be traded to V.H. Florence, LLC, Florence, Kentucky for a ``Walmart'' development project. The Kenton County Airport Board's 1.5 acres is located on the southern boundary of Cincinnati/Northern Kentucky International Airport; is a portion of a 238.774 acre parcel; and has no direct access except through adjoining airport property or adjacent V.H. Florence, LLC property, Boone County, Kentucky. The V.H. Florence, LLC's 1.5 acres is located on the southern boundary of Cincinnati/ Northern Kentucky International Airport; and has no direct access except through adjoining V.H. Florence, LLC property or adjacent airport property, Boone County, Kentucky.
Standard Instrument Approach Procedures, Weather Takeoff Minimums; Miscellaneous Amendments
This amendment establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) and/or Weather Takeoff Minimums for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, addition of new obstacles, or changes in air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.
Airworthiness Directives; Pratt & Whitney PW4000 Series Turbofan Engines
The FAA is superseding an existing airworthiness directive (AD) for Pratt & Whitney (PW) PW4000 series turbofan engines. That AD currently requires revisions to the engine manufacturer's time limits section (TLS) to include enhanced inspection of selected critical life- limited parts at each piece-part opportunity. This AD modifies the airworthiness limitations section of the manufacturer's manuals and an air carrier's approved continuous airworthiness maintenance program by adding eddy current inspections for front compressor hubs installed in PW 4000-94'' engine models. This AD also adds the PW4062A engine to the applicability. An FAA study of in-service events involving uncontained failures of critical rotating engine parts has indicated the need for mandatory inspections. The mandatory inspections are needed to identify those critical rotating parts with conditions, which if allowed to continue in service, could result in uncontained failures. We are issuing this AD to prevent critical life-limited rotating engine part failure, which could result in an uncontained engine failure and damage to the airplane.
Airworthiness Directives; Dowty Propellers Type R321/4-82-F/8, R324/4-82-F/9, R333/4-82-F/12, and R334/4-82-F/13 Propeller Assemblies
The FAA is superseding an existing airworthiness directive (AD) for Dowty Propellers Type R321/4-82-F/8, R324/4-82-F/9, R333/4-82- F/12, and R334/4-82-F/13 propeller assemblies. That AD currently requires initial and repetitive ultrasonic inspections of propeller hubs, part number (P/N) 660709201. This AD requires the same initial and repetitive ultrasonic inspections, but makes some needed corrections. This AD results from comments received on AD 2005-20-12. We are issuing this AD to prevent propeller hub failure due to cracks in the hub, which could result in loss of control of the airplane.
Airworthiness Directives; Fokker Model F27 Mark 050 Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to all Fokker Model F27 Mark 050 series airplanes. The existing AD currently requires using a torque wrench to repetitively tighten the screws for the attachment of the leading edges of the elevators, rudder, and ailerons. This new AD requires the same actions as those of the existing AD, but with reductions in the intervals for repetitive actions. This AD also requires modifying the elevator, rudder, and aileron leading edge attachments with additional locking devices. This AD results from a report of an in-flight vibration caused by a loose leading edge section of the elevator. We are issuing this AD to prevent binding of the flight controls caused by loose attachment screws, which could result in reduced controllability of the airplane.
Airworthiness Directives; Raytheon Aircraft Company, Model 390, Premier 1 Airplanes
The FAA adopts a new airworthiness directive (AD) for certain Raytheon Aircraft Company (Raytheon), Model 390, Premier 1 airplanes. For certain airplanes, this AD requires you (unless already done) to replace the plastic cover over the air conditioning motor module with a metallic cover and modify the air conditioning compressor motor module electromagnetic interference-radio frequency interference (EMI-RFI) filter located under the cover and reidentify the module part number. For all airplanes, the AD limits future installations of the cover for the air conditioner and the air conditioning compressor motor module. This AD results from reports that the plastic cover over the air conditioning motor module was found melted or burned and that the overheating of the EMI-RFI filter assembly located under the cover caused this damage. We are issuing this AD to prevent the melting or burning of the plastic cover. The burning of the plastic cover could result in a fire.
Airworthiness Directives; Shadin ADC-2000 Air Data Computers
The FAA adopts a new airworthiness directive (AD) for certain Shadin ADC-2000 air data computers (ADC) installed on airplanes. This AD requires you to replace affected ADC-2000 units with a modified unit. This AD results from reports that certain ADC-2000 units display incorrect altitude information on the Electronic Flight Information System (EFIS) to the pilot. We are issuing this AD to prevent ADC-2000 units, part numbers (P/Ns) 962830A-1-S-8, 962830A-2-S-8, and 962830A-3- S-8, configurations B, C, and D, from displaying incorrect altitude information. This could cause the flight crew to react to this incorrect flight information and possibly result in an unsafe operating condition.
