Airworthiness Directives; BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model BAe 146 and Model Avro 146-RJ airplanes. This proposed AD would require calculating the current life of each lift spoiler jack, and eventually replacing each lift spoiler jack. This proposed AD results from a review of all system components as part of the life-extension program for the affected airplanes that indicated the fatigue life limit of certain lift spoiler jacks cannot be extended from the current life limit. We are proposing this AD to prevent failure of the lift spoiler jack, and consequent increased drag and uncommanded roll inputs, which could reduce the flightcrew's ability to control 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 proposes to supersede an existing airworthiness directive (AD) that applies to all EMBRAER Model EMB-135 airplanes and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes. The existing AD requires repetitive inspections of the pitot static heating relay K0057 and corrective actions if necessary. The existing AD also requires doing a terminating modification, which ends the repetitive inspections. This proposed AD would remove the existing repetitive inspections and instead would require a one-time detailed inspection for damage of the relay, relay socket, and silicone gasket; applicable corrective actions; and a new action to modify and re- identify the relay socket. This proposed AD would also revise the existing terminating modificationreplacing/rerouting the windowsill drain hosesinto two parts, each with a different, reduced compliance time. This proposed AD results from a report of smoke in the cockpit. We are proposing this AD to prevent ignition of a windowsill drain hose by an overheated relay, which could cause fire and smoke in the cockpit.
Special Federal Aviation Regulation No. XX-Mitsubishi MU-2B Series Airplane Special Training, Experience, and Operating Requirements
The FAA is proposing a Special Federal Aviation Regulation (SFAR) applicable to the Mitsubishi MU-2B series airplane that would create new pilot training, experience, and operating requirements. Following an increased accident and incident rate in the MU-2B series airplane, the FAA conducted a safety evaluation of the MU-2B series airplane and found that changes in the training and operating requirements for that airplane are needed. These proposed regulations would mandate additional operating requirements and improve pilot training for the MU-2B series airplane.
Airworthiness Directives; BAE Systems (Operations) Limited Model BAe 146 Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain BAE Systems (Operations) Limited Model BAe 146 airplanes. This AD requires repetitive inspections to measure the depth of chafing or scoring in the skin along the full length of the wing-to-fuselage fairing from forward to aft ends at the contact between the seal and fuselage, and related investigative/corrective actions if necessary. This AD results from a report of chafing in this area. We are issuing this AD to detect and correct such chafing or scoring, which could result in reduced structural integrity of the fuselage.
Airworthiness Directives; Rolls-Royce Corporation Models 250-C30, 250-C40, and 250-C47 Series Turboshaft Engines
The FAA is adopting a new airworthiness directive (AD) for Rolls-Royce Corporation (RRC) models 250-C30, 250-40, and 250-C47 series turboshaft engines with a third-stage turbine wheel, part number (P/N) 6898663 or P/N 23065843 installed, or a fourth-stage turbine wheel, P/N 6892764 or P/N 23066744, installed. This AD adds an additional life limit for third- and fourth-stage turbine wheels. This AD results from analysis by RRC of failures of third-stage turbine wheels. We are issuing this AD to prevent loss of power, possible engine shutdown, or uncontained engine failure.
Airworthiness Directives; Airbus Model A319, A320, and A321 Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A319, A320, and A321 airplanes. This AD requires an inspection to determine if the stiff part of the girt and girt bar position of the forward left-hand and right-hand passenger doors is incorrect, and repair if necessary. This AD results from cases of girt bar disengagement from the floor fitting during deployment tests of slide rafts at the forward passenger doors. We are issuing this AD to prevent disengagement of the telescopic girt bar from the airplane when the door is opened in emergency situations, which could result in the inability to open the passenger door and to use the escape slide/raft at that door during an emergency evacuation of the airplane.
Airworthiness Directives; Airbus Model A310 Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Airbus Model A310 airplanes. This AD requires revising the Limitations section of the airplane flight manual by incorporating restrictions for high altitude operations. This AD results from several incidents of pitch oscillations with high vertical loads that occurred during turbulence at high altitudes. We are issuing this AD to prevent pitch oscillations during turbulence, which could result in reduced controllability of the airplane.
Airworthiness Directives; Boeing Model 747 Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 747 airplanes. That AD currently requires inspections to detect disbonding, corrosion, and cracking at the longitudinal rows of fasteners in the bonded skin panels in section 41 of the fuselage, and repair, if necessary. This new AD adds airplanes to the applicability, and requires new inspections of airplanes that may have Alodine-coated rivets installed. This AD results from a report of cracking discovered in a skin lap joint that was previously inspected using the eddy current method. We are issuing this AD to prevent rapid decompression of the airplane due to disbonding and subsequent cracking of the skin panels.
Airworthiness Directives; Bombardier Model DHC-8-102, -103, and -106 Airplanes, and Model DHC-8-200 and DHC-8-300 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model DHC-8-102, -103, and -106 airplanes, and Model DHC-8-200 and DHC-8-300 series airplanes. This AD requires performing a one-time general visual inspection for non-conforming chain links of chain assemblies of the elevator trim system and gust lock system, and corrective actions if necessary. This AD also requires temporary revisions to the airplane flight manuals of the affected airplanes, which describe procedures for elevator trim checks. This AD results from reports of several failures of the elevator trim chain, due to hydrogen embrittlement. We are issuing this AD to prevent breakage of the elevator trim chain, which would prevent the actual position of the elevator trim tab from being annunciated to the flightcrew. Attempting to adjust the trim tab from the full nose up or full nose down position with a broken trim chain could result in misleading information relative to takeoff trim settings and consequent loss of control on takeoff.
