Airworthiness Directives; Raytheon Aircraft Company Model 390 Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Raytheon Aircraft Company Model 390 airplanes. This proposed AD would require you to inspect the spigot bearing, part number (P/N) MS14104-16, for the proper position in the spigot fitting assembly and to install the wing spigot bearing retainer kit, P/N 390-4304-0001. This proposed AD results from two reports of the spigot bearing not being positioned flush with the fitting assembly, but protruding outside of the fitting assembly. We are proposing this AD to detect spigot bearings that are not positioned flush with the fitting assembly. This condition could result in the spigot bearing becoming disengaged from the fitting assembly, which could cause motion between the wing and the fuselage and degrade the structural integrity of the wing attachment to the fuselage. This could lead to wing separation and loss of control of the airplane.
Special Conditions; Avidyne Corporation, Inc.; Various Airplane Models; Protection of Systems for High Intensity Radiated Fields (HIRF)
These special conditions are issued to Avidyne Corporation, 55 Old Bedford Road, Lincoln, MA 01773, for a Supplemental Type Certificate for the models listed under the heading ``Type Certification Basis.'' This special condition includes various airplane models to streamline the certification process needed to improve the safety of the airplane fleet by fostering the incorporation of new technologies that can be certificated affordably under 14 CFR part 23. The airplanes listed under this multi-model approval will have novel and unusual design features when compared to the state of technology envisaged in the applicable airworthiness standards. These novel and unusual design features include the installation of the Entegra II Avionics System, consisting of: (2) Model 700-0003-( ) Integrated Flight Displays (IFD), (2) Model 700-00011-( ) Magnetometer/ OAT sensors, and (1) Model 700-00085-000 Keyboard/Controller. These components are all manufactured by Avidyne Corporation, Inc. The applicable regulations do not contain adequate or appropriate airworthiness 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 the airworthiness standards applicable to these airplanes.
Public Notice for a Change in Use of Aeronautical Property at Portland International Jetport, Portland, ME
The FAA is requesting public comment on the City of Portland's request to swap approx. 1.44 acres of aeronautical use property with the State of Maine. The parcels are located off Brickhill Avenue, South Portland, and were once part of the Maine Youth Center. The swap will straighten the property boundary allowing for both the City and State to develop both parcels to their maximum potential. The parcel to be conveyed to the Jetport will be used for aeronautical purposes. The parcel conveyed to the State will be used for automobile parking. The property was acquired under AIP Project No. 3-23-0038-54-2003. The disposition of proceeds from the disposal of airport property will be in accordance with FAA's Policy and Procedures Concerning the Use of Airport Revenue, published in the Federal Register on February 16, 1999.
Airworthiness Directives; Rolls-Royce plc RB211 Series Turbofan Engines
The FAA is superseding an existing airworthiness directive (AD) for Rolls-Royce plc (RR) RB211-22B series, RB211-524B, -524C2, - 524D4, -524G2, -524G3, and -524H series, and RB211-535C and -535E series turbofan engines with high pressure compressor (HPC) stage 3 disc assemblies, part numbers (P/Ns) LK46210, LK58278, LK67634, LK76036, UL11706, UL15358, UL22577, UL22578, and UL24738 installed. This AD requires removing from service certain disc assemblies before they reach their full published life if not modified with anticorrosion protection. This AD results from the manufacturer's reassessment of the corrosion risk on HPC stage 3 disc assemblies that have not yet been modified with sufficient application of anticorrosion protection. We are issuing this AD to prevent corrosion-induced uncontained disc failure, resulting in damage to the airplane.
Airworthiness Directives; Airbus Model A318, A319, A320, and A321 Airplanes
The FAA is superseding an existing airworthiness directive (AD) that applies to certain Airbus Model A319, A320, and A321 airplanes. The existing AD currently requires a one-time ultrasonic inspection for certain airplanes, and repetitive detailed inspections for all airplanes, for cracking in the forward lug of the support rib 5 fitting of both main landing gear (MLG), and repair if necessary. The existing AD also provides for optional terminating actions. This AD removes the requirement for the one-time ultrasonic inspection and reduces the compliance time and repetitive interval for the detailed inspection of all airplanes. This AD also adds certain Airbus Model A318 airplanes to the applicability. This AD continues to provide optional terminating action for certain airplanes, as well as other optional methods of complying with the AD's requirements. This AD results from a new crack that was found in the forward lug of the MLG support rib 5 fitting. We are issuing this AD to detect and correct cracking in the forward lug of the MLG, which could result in failure of the lug and consequent collapse of the MLG during takeoff or landing.
Airworthiness Directives; Viking Air Limited Model DHC-7 Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Viking Air Limited Model DHC-7 airplanes. This AD requires implementing a corrosion prevention and control program (CPCP) either by accomplishing specific tasks or by revising the maintenance inspection program to include a CPCP. This AD results from a determination that, as airplanes age, they are more likely to exhibit indications of corrosion. We are issuing this AD to prevent structural failure of the airplane due to corrosion.
Airworthiness Directives; Airbus Model A300 B4-600R and A300 F4-600R Series Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Airbus Model A300 B4-600R and A300 F4-600R series airplanes. That AD currently requires repetitive inspections for damage of the center tank fuel pumps and fuel pump canisters and replacement of any damaged parts, and mandates modification of the canisters of the center tank fuel pumps, which terminates the repetitive inspections. For certain airplanes, this new AD requires a one-time inspection of the attachment bolts of the outlet flange of the canisters of the center tank fuel pumps for bolts that are too short and do not protrude through the nut, and replacement of the bolts if necessary. This AD results from several reports that the attachment bolts for the canisters, modified by the requirements in the existing AD, are too short and do not fully protrude from the nuts. We are issuing this AD to prevent damage to the fuel pump and fuel pump canister, which could result in loss of flame trap capability and could provide a fuel ignition source in the center fuel tank.
