Airworthiness Directives; BAE SYSTEMS (OPERATIONS) LIMITED Airplanes
Document Number: 2012-5380
Type: Proposed Rule
Date: 2012-03-06
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain BAE SYSTEMS (OPERATIONS) LIMITED Model BAe 146 and Avro 146-RJ airplanes. This proposed AD was prompted by a report of a crack found on the left-hand sidewall well on the nose landing gear (NLG). This proposed AD would require performing a repetitive high frequency eddy current inspection of the stiffeners on the left-hand sidewall on the NLG gear bay for cracks, and repair or replace the sidewall if necessary. Replacing the sidewall with a certain sidewall part number constitutes a terminating action for the repetitive inspections. We are proposing this AD to detect and correct failure of the sidewall, which could result in consequent in-flight rapid decompression of the cabin and injury to the passengers.
Airworthiness Directives; BAE SYSTEMS (Operations) Limited Airplanes
Document Number: 2012-5379
Type: Proposed Rule
Date: 2012-03-06
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all BAE SYSTEMS (Operations) Limited Model 4101 airplanes. This proposed AD was prompted by reports of cracking found in the wing rear spar. This proposed AD would require a one-time detailed inspection for cracks, corrosion, and other defects of the rear face of the wing rear spar, and repair if necessary. We are proposing this AD to detect and correct cracking in the rear spar, which could propagate to a critical length, possibly affecting the structural integrity of the area and resulting in a fuel tank rupture, with consequent damage to the airplane and possible injury to its occupants.
Amendment of Class E Airspace; Springfield, TN
Document Number: 2012-5123
Type: Rule
Date: 2012-03-06
Agency: Federal Aviation Administration, Department of Transportation
This action amends Class E Airspace in the Springfield, TN area. Aydelotte Airport has been abandoned and controlled airspace is no longer needed. Airspace reconfiguration is necessary for the continued safety and airspace management of Instrument Flight Rules (IFR) operations within the Springfield, TN airspace area. This action also makes a minor adjustment to the geographic coordinates of the Springfield Robertson County Airport.
Airworthiness Directives; Bombardier, Inc. Airplanes
Document Number: 2012-4805
Type: Rule
Date: 2012-03-06
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2B16 (CL-604 Variant) airplanes. This AD was prompted by reports of the air-driven generator (ADG) failing to provide power during operational/function checks due to wires in the ADG power feeder cables being damaged. The damage was due to galvanic corrosion and inadequate silver-plating. This AD requires replacing ADG power feeder cables. We are issuing this AD to prevent galvanic corrosion on ADG power feeder cables, which could result in damage to the cable and consequently the cable may not be able to provide emergency electrical power to the airplane.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2012-4520
Type: Rule
Date: 2012-03-06
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP series airplanes. This AD requires inspections for scribe lines in affected lap and butt splices, wing-to-body fairing locations, and external repair and cutout reinforcement areas; and related investigative and corrective actions if necessary. This AD was prompted by reports of scribe lines found at lap joints and butt joints, around external doublers and antennas, and at locations where external decals had been cut. We are issuing this AD to detect and correct scribe lines, which can develop into fatigue cracks in the skin and cause sudden decompression of the airplane.
Airworthiness Directives; Bombardier, Inc. Airplanes
Document Number: 2012-4494
Type: Rule
Date: 2012-03-06
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Model DHC-8-102, -103, and -106 airplanes and Model DHC-8-200, -300, and -400 series airplanes. This AD was prompted by reports of cracking of the DHC-8 Series 100 rudder actuator mounting bracket. This AD requires modifying the mounting adapters of the power control unit (PCU). We are issuing this AD to prevent loss of both rudder PCU actuators which could result in free play of the rudder control surface and loss of controllability of the airplane.
