Airworthiness Directives; Fokker Model F27 Mark 050 Airplanes

Mon, Dec 12 2005 11:00:00 GMT

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 inflight 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; Pratt & Whitney PW4000 Series Turbofan Engines

Mon, Dec 12 2005 11:00:00 GMT

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 piecepart 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 400094'' engine models. This AD also adds the PW4062A engine to the applicability. An FAA study of inservice 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 lifelimit

The FAA is superseding an existing airworthiness directive (AD) for

Pratt & Whitney (PW) JT8D1, 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 piecepart 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 inservice 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 lifelimited rotating engine part failure, which could resu

Airworthiness Directives; Raytheon Aircraft Company, Model 390, Premier 1 Airplanes

Mon, Dec 12 2005 11:00:00 GMT

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 interferenceradio frequency interference (EMIRFI) 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 EMIRFI 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

Mon, Dec 12 2005 11:00:00 GMT

The FAA adopts a new airworthiness directive (AD) for certain Shadin ADC2000 air data computers (ADC) installed on airplanes. This AD requires you to replace affected ADC2000 units with a modified unit. This AD results from reports that certain ADC2000 units display incorrect altitude information on the Electronic Flight Information System (EFIS) to the pilot. We are issuing this AD to prevent ADC2000 units, part numbers (P/Ns) 962830A1S8, 962830A2S8, and 962830A3 S8, 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.

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

Mon, Dec 12 2005 11:00:00 GMT

The FAA is superseding an existing airworthiness directive (AD) for Dowty Propellers Type R321/482F/8, R324/482F/9, R333/482 F/12, and R334/482F/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 20052012. 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.

Standard Instrument Approach Procedures, Weather Takeoff Minimums; Miscellaneous Amendments

Mon, Dec 12 2005 11:00:00 GMT

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; Boeing Model 767-300 and -300F Series Airplanes

Mon, Dec 12 2005 11:00:00 GMT

The FAA withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD) for certain Boeing Model 767300
[[Page 73393]]
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 realignment 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

Mon, Dec 12 2005 11:00:00 GMT

The FAA proposes to supersede an existing airworthiness directive (AD) for General Electric Company (GE) CF645/50 series turbofan engines. That AD currently requires an initial and repetitive onwing visual inspection of the side links of the fivelink forward mount assembly for cracks, and replacement of the side links and pylon attachment bolts and inspection of the failsafe bolt and platform lug if the side links are cracked. That AD also requires a shoplevel refurbishment of the side links as a terminating action to the onwing 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 CF680A 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.
