Special Conditions: Cessna Model 650 Airplanes; High-Intensity Radiated Fields (HIRF)
These special conditions are issued for Cessna Model 650 airplanes modified by Elliott Aviation Technical Product Development, Inc. These modified airplanes will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. The modification incorporates the installation of electronic flight display systems manufactured by Universal Avionics Systems Corporation. The electronic flight display systems perform critical functions. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for the protection of these systems from the effects of high-intensity radiated fields (HIRF). These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
Approval of Noise Compatibility Program Update for Lehigh Valley International Airport, Allentown, PA
The Federal Aviation Administration (FAA) announces its findings on the noise compatibility program submitted by the Lehigh- Northampton Airport Authority under the provisions of 49 U.S.C. (the Aviation Safety and Noise Abatement Act, hereinafter referred to as ``the Act'') and 14 CFR Part 150. These findings are made in recognition of the description of Federal and nonfederal responsibilities in Senate Report No. 96-52 (1980). On May 14, 2004 the FAA determined that the noise exposure maps submitted by the Lehigh- Northampton Airport Authority under Part 150 were in compliance with applicable requirements. On October 7, 2005, the FAA approved the Lehigh Valley International Airport's updated noise compatibility program. Most of the recommendations of the program update were approved. One program element relating to revised flight procedures for noise abatement was proposed by the airport operator and was approved in part, as a voluntary measure, and disapproved in part. Only one noise abatement element was disapproved for purposes of Part 150 pending submission of additional information needed to make an informed analysis. The Lehigh-Northampton Airport Authority has also requested under FAR Part 150, section 150.35(f), that FAA determine that the revised five-year forecast condition NEM submitted with the noise compatibility program and showing noise contours as a result of the implementation of the noise compatibility program is in compliance with applicable requirements of FAR Part 150. The FAA announces its determination that the revised five-year forecast condition NEW for the Lehigh Valley International Airport for the year 2008 submitted with the noise compatibility program is in compliance with applicable requirements of FAR Part 150 effective October 31, 2005. The documentation that constitutes the revised five-year forecast condition NEM as defined in Sec. Sec. 150.7 and 150.101(e) of Part 150 includes but is not limited to: Sections 2.2 and 2.3, Figure 3, and Table 3 in the NCP Update, and Figure 11 and Figures 36 through 45 in the NEM volume. The FAA has determined that this revised five-year forecast condition NEM and accompanying documentation are in compliance with applicable requirements.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170 Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170 airplanes. This AD requires repetitively replacing the low-stage check valve and associated seals of the right-hand engine bleed system. This AD results from a report that an engine shut down during flight due to the failure of the low-stage check valve to close. We are issuing this AD to prevent failure of the low-stage check valve, which could result in an engine shutting down during flight.
Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This AD requires revising the Airworthiness Limitations section of the Instructions for Continued Airworthiness of the Canadair Regional Jet Maintenance Requirements Manual by incorporating new procedures for repetitive detailed and special detailed inspections for cracking of the aft pressure bulkhead. This AD results from a fatigue test, which revealed cracking of the aft pressure bulkhead; subsequent in-service reports show that fatigue cracking has been found on other airplanes. We are issuing this AD to detect and correct cracking in the aft pressure bulkhead, which could result in reduced structural integrity and rapid decompression of the airplane.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135 Airplanes, and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain EMBRAER Model EMB-135 airplanes, and Model EMB-145, -145ER, - 145MR, -145LR, -145XR, -145MP, and -145EP airplanes. This AD requires modification of the logic of the steering system of the nose landing gear (NLG) wheel. This AD results from reports of the loss of directional control of the airplane on the ground after an internal failure of the NLG wheel steering system. We are issuing this AD to prevent failure of the NLG wheel steering system, which could result in reduced controllability of the airplane.
Airworthiness Directives; Learjet Model 23, 24, 24A, 24B, 24B-A, 24C, 24D, 24D-A, 24E, 24F, 24F-A, 25, 25A, 25B, 25C, 25D, and 25F Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Learjet Model 23, 24, 24A, 24B, 24B-A, 24C, 24D, 24D-A, 24E, 24F, 24F-A, 25, 25A, 25B, 25C, 25D, and 25F airplanes. This AD requires replacement of the spherical accumulator for the main hydraulic system with a new cylindrical accumulator. For certain airplanes, this AD also requires modification of the accumulator pressure gauge. This AD results from reports of the failure of two thrust reverser accumulators (which are similar to the main hydraulic system's spherical accumulator) and fatigue cracks found on four thrust reverser accumulators. We are issuing this AD to prevent failure of the spherical accumulator for the main hydraulic system, due to fatigue cracking on the threads, which could result in the loss of hydraulic power, damage to the surrounding airplane structure, and loss of airplane control. The failure of the accumulator could also result in injury to any persons in the surrounding area. The loss of hydraulic fluid could also leak onto a potential source of ignition and result in a consequent fire.
Airworthiness Directives; Airbus Model A319-100 Series Airplanes, Model A320-111 Airplanes, Model A320-200 Series Airplanes, and Model A321-100 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A319-100 series airplanes, Model A320-111 airplanes, Model A320-200 series airplanes, and Model A321-100 series airplanes equipped with any additional center tank (ACT). This AD requires identifying the part number of the ACT and, for certain ACTs, replacing the outer ACT manhole cover and seal. This AD results from reports of an ACT fuel transfer failure due to air leakage around the seal of the outer manhole covers of the ACTs. We are issuing this AD to prevent this leakage, which could result in fuel or fuel vapor leaking into the cargo compartment, and consequent increased risk of a fire in the cargo compartment.
Airworthiness Directives; Saab Model SAAB 2000 Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Saab Model SAAB 2000 airplanes. This AD requires modifying the manual feather-and-unfeather system for the propellers to make the design of the system more robust. This AD results from reports of in- flight engine shutdown caused by uncommanded operation of the feather pump of the propeller. We are issuing this AD to prevent uncommanded feathering of the propeller, which could result in the shutdown of an engine during flight and consequent reduced controllability of the airplane.
Airworthiness Directives; Airbus Model A319-100, A320-200, and A321-100 and -200 Series Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Airbus Model A319-100, A320-200, and A321-100 and -200 series airplanes. That AD currently requires modification of the telescopic girt bar of the escape slide/raft assembly, and follow-on actions. This new AD requires a new modification of the telescopic girt bar and the installation of placards on the modified girt bars, which terminates the repetitive functional tests required by the existing AD. This AD results from development of a new, improved modification. We are issuing this AD to prevent failure of the escape slide/raft to deploy correctly, which could result in the slide being unusable during an emergency evacuation and consequent injury to passengers or airplane crewmembers.
Airworthiness Directives; Airbus Model A300 B4-600 and A300 B4-600R Series Airplanes; and A300 F4-605R and A300 C4-605R Variant F Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to all Airbus Model A300 B4-600 and A300 B4-600R series airplanes, and all Model A300 F4-605R airplanes. That AD currently 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 new AD revises certain inspection thresholds and intervals. This new AD also adds inspections to detect cracks of additional attachment holes. This AD results from 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 issuing this AD to prevent fatigue cracking of the forward fitting of fuselage frame FR47, which could result in reduced structural integrity of the frame.
Airworthiness Directives; Learjet Model 23, 24, 24A, 24B, 24B-A, 24D, 24D-A, 24E, 24F, 25, 25A, 25B, 25C, 25D, and 25F Airplanes Modified by Supplemental Type Certificate SA1731SW, SA1669SW, or SA1670SW
The FAA is adopting a new airworthiness directive (AD) for certain Learjet Model 23, 24, 24A, 24B, 24B-A, 24D, 24D-A, 24E, 24F, 25, 25A, 25B, 25C, 25D, and 25F airplanes. This AD requires removing the thrust reverser accumulator, and making the thrust reverser hydraulic system and the thrust reversers inoperable. This AD results from reports of the failure of two thrust reverser accumulators. We are issuing this AD to prevent failure of the thrust reverser accumulators, due to fatigue cracking on the female threads, which could result in the loss of hydraulic power and damage to the surrounding airplane structure.
Airworthiness Directives; Airbus Model A330-200 and A330-300 Series Airplanes; and Model A340-200 and A340-300 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Airbus Model A330-200 and A330-300 series airplanes; and Model A340-200 and A340-300 series airplanes. This AD requires an accelerated schedule of repetitive testing of the elevator servo control loops, and corrective actions if necessary. This AD results from reports of failed elevator servo controls due to broken guides. We are issuing this AD to ensure proper functioning of the elevator servo controls. Failure of the elevator servo controls during certain phases of takeoff could result in an unannounced loss of elevator control and consequent reduced controllability of the airplane.
