Airworthiness Directives; Bell Helicopter Textron Canada Helicopters
We propose to adopt a new airworthiness directive (AD) for Bell Helicopter Textron Canada (BHTC) Model 407 helicopters with certain tailboom assemblies installed. This proposed AD would require, at specified intervals, inspecting the tailboom assembly for a crack, loose rivet, or other damage. This proposed AD is prompted by a stress analysis of the tailboom skin that revealed high-stress-concentration areas are susceptible to skin cracking. This condition, if not detected, could result in a crack in the tailboom assembly, failure of the tailboom, and subsequent loss of control of the helicopter.
Airworthiness Directives; Eurocopter Deutschland GmbH Helicopters
We propose to adopt a new airworthiness directive (AD) for the Eurocopter Deutschland GmbH (Eurocopter) Model MBB-BK 117 C-2 helicopters. This proposed AD would require changing the direction of the bolt connecting the upper clevis bolt of a specific bellcrank in the main rotor assembly, repetitively inspecting the bearings in the bellcrank assemblies for correct staking, and replacing a bellcrank if a bearing is staked incorrectly. This proposed AD is prompted by improperly staked bellcrank bearings, which may cause the bellcrank to shift in the axial direction and cause chafing. The proposed actions are intended to prevent contact between the bolts on certain main rotor bellcranks, which could result in chafing and subsequent loss of control of the helicopter.
Fifth Meeting: RTCA Special Committee 227, Standards of Navigation Performance
The FAA is issuing this notice to advise the public of the fifth meeting of the RTCA Special Committee 227, Standards of Navigation Performance.
Airworthiness Directives; EADS CASA (Type Certificate Previously Held by Construcciones Aeronáuticas, S.A.) Airplanes
We are adopting a new airworthiness directive (AD) for all EADS CASA (Type Certificate previously held by Construcciones Aeron[aacute]uticas, S.A.) Model CN-235, CN-235-100, CN-235-200, and CN-235-300 airplanes. This AD was prompted by reports of incorrect electrical polarity connections on engine fire extinguishing discharge cartridges. This AD requires a one-time inspection to identify the correct polarity for each pair of electrical connectors on each engine fire extinguisher cartridge, and repair if necessary. We are issuing this AD to detect and correct incorrect polarity connections, which could prevent the actuation of the discharge cartridge in case of automatic fire detection or manual initiation during a potential engine fire, and could result in damage to the airplane and injury to passengers.
Airport Improvement Program
This notice announces the request for comments on the draft of FAA Order 5100-38D, Airport Improvement Program Handbook. When finalized, this Order will replace Order 5100-38C, Airport Improvement Program Handbook, issued on June 28, 2005. This update clarifies statutory requirements, including changes to the AIP statute from the recent FAA reauthorization.
Airworthiness Directives; Airbus Airplanes
We are adopting a new airworthiness directive (AD) for all Airbus Model A330-200 Freighter series airplanes; Model A330-200 and - 300 series airplanes; and Model A340-200 and -300 series airplanes. This AD was prompted by a report of a manufacturing defect in certain rods installed in the belly fairing, which could lead to cracks at the crimped end of the rod. This AD requires an inspection of the rods to determine the manufacturer; and for affected parts, an inspection for any cracking of the rods, and related investigative and corrective actions if necessary. We are issuing this AD to detect and correct cracking of the rods, which could result in rupture of rods that attach the belly fairing to the airframe, leading to separation of the belly fairing from the airframe, and consequent damage to airplane structure and airplane systems.
Airworthiness Directives; Airbus Airplanes
We are adopting a new airworthiness directive (AD) for all Airbus Model A310-203 airplanes. This AD was prompted by a report of an analysis that demonstrated a reduced fatigue life for the side link bolts, center sway link bolts, and thrust link bolts on the forward engine mounts. This AD requires repetitive replacement of those bolts. We are issuing this AD to prevent deterioration of the structural integrity of the bolts, which could result in possible damage to an engine or wing.
Airworthiness Directives; BAE SYSTEMS (OPERATIONS) LIMITED Airplanes
We are adopting a new airworthiness directive (AD) for all BAE SYSTEMS (OPERATIONS) LIMITED Model BAe 146, and Avro 146-RJ series airplanes. This AD was prompted by a report of loss of the end caps on the anti-icing piccolo tube of the wing leading edge. This AD requires a detailed inspection of the end caps on the anti-icing piccolo tube for lost or loose end caps, and replacing or repairing the end caps if necessary. We are issuing this AD to detect and correct lost and loose end caps on the anti-icing piccolo tube, and ice accretion on the wing leading edge or run-back ice, which could lead to a reduction in the stall margin on approach and loss of controllability of the airplane.
