That AD currently requires repetitive inspections to detect fatigue cracking in the upper deck floor beams located at certain body stations, and repair, if necessary. This new AD lowers the threshold for the existing inspections and requires new repetitive inspections of previously repaired areas, and repair if necessary. This AD is prompted by the results of an additional detailed analysis that indicate fatigue cracks can initiate sooner than has previously been observed. We are issuing this AD to prevent failure of the upper deck floor beams at certain body stations due to fatigue cracking, which could result in rapid decompression and reduced controllability of the airplane.

Fairchild Aircraft, Inc. SA226 and SA227 Series Airplanes
The FAA is adopting a new Airworthiness Directive (AD) to supersede AD 99-06-02, which currently applies to certain Fairchild Aircraft (Fairchild) SA226 and SA227 series airplanes. AD 99-06-02 requires you to repetitively inspect the wing spar center web cutout on both wings for cracks between Wing Station (WS) 8 and WS 17.5. That AD also requires you to repair any area found cracked before further flight. The repair will eliminate the need for the repetitive inspections on that particular wing spar. Since that AD became effective, we have determined that we inadvertently omitted certain Model SA227-CC/DC airplane serial numbers from the applicability. This AD retains the actions of AD 99-06-02 and adds additional Model SA227- CC/DC airplanes to the Applicability section. The actions specified in this AD are intended to detect and correct fatigue cracking of the wing spar center web cutout area, which could result in structural failure of the wing spar. This could lead to loss of control of the airplane.

British Aerospace Model BAe 146 and Model Avro 146-RJ Series Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to certain British Aerospace Model BAe 146 and Model Avro 146-RJ series airplanes. That AD currently requires a one- time measurement of the thickness of the outer links on the side stays of the main landing gear (MLG), and related investigative and corrective actions as necessary; and provides for replacement of a thin outer link with a new or serviceable part in lieu of certain related investigative inspections. This new AD requires repetitive inspections for cracking of the outer links on the MLG side stays, and corrective actions if necessary. This new action also expands the applicability, provides for optional terminating action for the repetitive inspections, and reduces the repetitive inspection interval. This AD is prompted by new crack findings on airplanes not subject to the existing AD, and the determination that the profile gauge's slipping over the outer link profile is not a factor in the identified unsafe condition. We are issuing this AD to prevent cracking of the outer links of the MLG side stays, which could result in failure of a side stay and consequent collapse of the landing gear.

The FAA is superseding an existing airworthiness directive (AD) for General Electric Company (GE) CF34-8C1 series and CF34-8C5 series turbofan engines, with certain serial number (SN) master variable geometry (VG) actuators installed. That AD currently requires initial and repetitive reviews of the airplane Maintenance Data Computer (MDC) for master VG actuator fault messages, and if the MDC is inoperative, reviews of the Engine Indication and Crew Alerting System (EICAS) for fault messages. That AD also requires replacing actuators reported faulty by the Full Authority Digital Engine Control (FADEC). This ad requires those same actions, and expands the applicability to additional actuators by part number (P/N) and SN. This AD also prohibits installation of affected master VG actuators onto any CF34- 8C1 and CF34-8C5 engine after the effective date of this AD. This AD results from the need to add to the list of affected parts, master VG actuators made by parts manufacturer approval (PMA). We are issuing this AD to prevent dual-channel electrical signal faults in the VG master actuator, which will cause an uncommanded reduction of thrust to idle with a subsequent loss of the ability to advance thrust above idle, and which will result in a multiengine loss of thrust if dual- channel faults occur on more than one engine simultaneously.
