Airworthiness Directives; Raytheon Aircraft Company Model 390 Airplanes
The FAA is adopting a new airworthiness directive (AD) to supersede AD 2006-02-51, which applies to certain Raytheon Aircraft Company Model 390 airplanes. AD 2006-02-51 currently requires you to inspect the left engine hydraulic pump outlet tube and the clamp; replace the clamp at each inspection; replace the hydraulic pump outlet tube immediately if any problem is found; and report the results of each inspection or replacement to the FAA. This AD is the result of several hydraulic pump outlet tube failures after issuance of AD 2006- 02-51, including failures on the right engine. This AD requires you to visually inspect the hydraulic pump outlet tube on both engines on a recurring basis and immediately replace the tube if damage is found. This AD also requires incorporation of an Airplane Flight Manual (AFM) change to not allow operation of an engine with its associated firewall hydraulic shutoff valve closed. In addition, this AD requires you to replace the hydraulic pump outlet tube if an engine is operated with its firewall hydraulic shutoff valve closed. We are issuing this AD to prevent failure of the hydraulic pump outlet tube and consequent leaking of hydraulic fluid. Such leakage could result in a fire. There is also a risk of loss of hydraulic system functions including normal gear extensions, speed brakes, roll spoilers, lift dump, and normal brakes.
Airworthiness Directives; Fokker Model F.28 Mark 0070 and 0100 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Fokker Model F.28 Mark 0070 and 0100 airplanes. This proposed AD would require inspecting the carbon-fiber reinforced plastic (CFRP) main landing gear (MLG) door to determine whether certain part numbers are installed. For airplanes having certain doors, this proposed AD would require inspecting the MLG outboard door for cracks, play, and loose sealant/bolts/nuts, and related investigative and corrective actions if necessary. This proposed AD would also require, for airplanes having certain doors, modifying the rod bracket attachment of the MLG outboard door. This proposed AD results from a report of a rod bracket of the MLG door detaching during flight. We are proposing this AD to detect and correct cracks in the rod bracket attachment bolts, which could result in the rod brackets detaching from the MLG door and blocking the proper functioning of the MLG.
Airworthiness Directives; Airbus Model A330 Airplanes and A340-200 and -300 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A330 airplanes and A340-200 and -300 series airplanes. For certain airplanes, this proposed AD would require inspecting to determine the part number of certain S4- and MZ-type spoiler servo-controls (SSCs). For certain other airplanes, this proposed AD would require inspecting to determine the part number of all SSCs. This proposed AD would also require replacing any affected SSC with a new SSC. This proposed AD results from a new load duty cycle defined by the manufacturer. Additional fatigue tests and calculations done on this basis indicated that the spoiler valve manifold of the S4- type SSCs, and, on certain airplanes, the maintenance cover of the MZ- type SSCs, may crack during its service life due to pressure impulse fatigue. We are proposing this AD to prevent fatigue cracking of certain SSCs, which could result in hydraulic leakage and consequent loss of SSC function and loss of the associated hydraulic system. These conditions could affect all three hydraulic systems, which could result in reduced controllability of the airplane.
Airworthiness Directives; Airbus Model A319, A320, and A321 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A319, A320, and A321 airplanes. This proposed AD would require installing spacer assemblies at the attachment points of the YZ-latches of the cargo loading system in the forward and aft cargo compartments, as applicable. This proposed AD results from tests that have shown that the attachment points of the YZ-latches of the cargo loading system fail under maximum loads. We are proposing this AD to prevent failure of the attachment points of the YZ-latches, which could result in unrestrained cargo causing damage to the fire protection system, hydraulic system, electrical wiring, or other equipment located in the forward and aft cargo compartments. This damage could adversely affect the continued safe flight of the airplane.
Airworthiness Directives; Fokker Model F.28 Mark 0070 and 0100 Airplanes
The FAA is revising an earlier NPRM for an airworthiness directive (AD) that applies to certain Fokker Model F.28 Mark 0070 and 0100 airplanes. The original NPRM would have superseded an existing AD that currently requires a one-time inspection of the sliding members in the main landing gear (MLG) for cracking and replacement of the sliding members with serviceable parts if necessary. The original NPRM proposed to require repetitive magnetic particle inspections of the sliding members of the MLG for cracking and corrective actions as necessary. The original NPRM resulted from inspection findings that have shown repetitive inspections are needed to establish fleet safety. This new action revises the original NPRM by correcting a certain part number in the applicability. We are proposing this supplemental NPRM to detect and correct fatigue cracking of the sliding member, which could result in possible separation of the MLG from the airplane and consequent reduced controllability of the airplane upon landing and possible injury to passengers.
Airworthiness Directives; Bombardier Model CL-600-2B16 (CL-604) Airplanes and Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes
The FAA is revising an earlier NPRM for an airworthiness directive (AD) that applies to certain Bombardier Model CL-600-2B16 (CL-604) airplanes and Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. These models may be referred to by their marketing designations as RJ100, RJ200, RJ440, CRJ100, CRJ200, CRJ440, and CL-65. The original NPRM would have superseded an existing AD that currently requires revising the Emergency Procedures section of the airplane flight manual (AFM) to advise the flightcrew of additional procedures to follow in the event of stabilizer trim runaway. The existing AD also requires revising the Abnormal Procedures section of the AFM to advise the flightcrew of procedures to follow in the event of MACH TRIM, STAB TRIM, and horizontal stabilizer trim malfunctions. The existing AD also requires revising the Normal section of the AFM to require a review of the location of certain circuit breakers and a functional check of the stabilizer trim system. In addition, the existing AD requires installing circuit breaker identification collars and provides an optional terminating action for the requirements of the AD. The original NPRM proposed to require doing the previously optional terminating action (installation of a new horizontal stabilizer trim control unit). The original NPRM resulted from a determination that the terminating action is necessary to address reports of uncommanded horizontal stabilizer trim motion. This new action revises the original NPRM by not allowing the removal of applicable temporary revisions (TRs) to the Emergency and Abnormal Procedures sections of the AFM and by adding the proposed requirement for certain airplanes to re-insert the applicable TRs of the Emergency and Abnormal Procedures sections of the AFM under certain conditions. We are proposing this supplemental NPRM to prevent horizontal stabilizer trim uncommanded motion, which could result in reduced controllability of the airplane.
Standard Instrument Approach Procedures; Miscellaneous Amendments
This amendment amends Standard Instrument Approach Procedures (SIAPs) for operations at certain airports. These regulatory actions are needed 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.
Modification of Class E Airspace; Creston, IA
This action amends Title 14 Code of Federal Regulations, part 71 (14 CFR 71) by modifying the Class E airspace area at Creston Municipal Airport, IA. An examination of controlled airspace for Creston, IA, revealed discrepancies in the legal description for the Class E airspace area. The intended effect of this rule is to provide controlled airspace of appropriate dimensions to protect aircraft executing Standard Instrument Approach Procedures (SIAP) to Creston Municipal Airport.
