Airworthiness Directives; Boeing Model 747 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Boeing Model 747 airplanes. This proposed AD would require an inspection of the number (No.) 2 and No. 3 windows on the left and right sides of the airplane to determine their part numbers, and related investigative and corrective actions if necessary. This proposed AD results from loss of a No. 3 window in-flight. We are proposing this AD to detect and correct cracking in the fail-safe interlayer of certain No. 2 and No. 3 glass windows, which could result in loss of the window and consequent rapid loss of cabin pressure. Loss of the window could also result in crew communication difficulties or incapacitation of the crew.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170-100 LR, -100 STD, -100 SE, -100 SU, -200 LR, -200 STD, and -200 SU Airplanes and Model ERJ 190 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain EMBRAER Model ERJ 170-100 LR, -100 STD, -100 SE, -100 SU, - 200 LR, -200 STD, and -200 SU airplanes and Model ERJ 190 airplanes. This proposed AD would require inspecting to determine the part number and serial number of the deployment actuator of the ram air turbine (RAT) and related investigative and corrective actions if necessary. This proposed AD results from reports that the RAT may not fully deploy due to galling between the piston rod and gland housing of the deployment actuator. We are proposing this AD to prevent the RAT from failing to deploy, which could result in loss of control of the airplane during in-flight emergencies.
Airworthiness Directives; Airbus Model A318, A319, A320, and A321 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Model A318, A319, A320, and A321 airplanes. This proposed AD would require repetitive inspections of the operation of the main landing gear (MLG) door opening sequence to determine if a defective actuator is installed, and replacing any defective actuator with a new actuator. This proposed AD results from reports of slow operation of the MLG door opening/closing sequence due to a defective actuator. We are proposing this AD to detect and correct defective actuators of the MLG door, which could result in slow operation of the MLG door and consequent non-extension of the MLG during an emergency freefall operation.
Airworthiness Directives; Airbus Model A318, A319, A320, and A321 Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Airbus Model A318-100 and A319-100 series airplanes, Model A320-111 airplanes, and Model A320-200, A321- 100, and A321-200 series airplanes. The existing AD currently requires repetitive inspections of the upper and lower attachments of the trimmable horizontal stabilizer actuator (THSA) to measure for proper clearance and to detect cracks, damage, and metallic particles. The existing AD also requires corrective actions, if necessary, and reports of inspection findings. This proposed AD would shorten the repetitive interval for inspecting the upper THSA attachment. This proposed AD results from new test results on the secondary load path, which indicated the need to shorten the repetitive interval for inspecting the upper THSA attachment. We are proposing this AD to detect and correct failure of the THSA's primary load path, which could result in latent (undetected) loading and eventual failure of the THSA's secondary load path and consequent uncontrolled movement of the horizontal stabilizer and loss of control of the airplane.
