2010-04-06: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: An in-flight engine shutdown incident was reported on an aircraft equipped with a TAE 125-01 engine. This was found to be mainly the result of a blockage of the scavenge oil gear pump due to a broken axial bearing of the turbocharger. The broken parts were sucked into the oil pump and caused seizure. With the pump inoperative, the separator overfilled, causing the engine oil to escape via the breather vent line. This caused a loss of oil that resulted in the engine overheating and subsequent shutdown. We are issuing this AD to prevent engine in-flight shutdown, possibly resulting in reduced control of the aircraft.
2001-15-24: This amendment adopts a new airworthiness directive (AD), applicable to certain Bombardier Model CL-600-2B16 series airplanes, that requires modification of the wiring for the internal fuel/defuel panel. The actions specified by this AD are intended to prevent the loss of engine and fuel indications essential for safe flight and landing. This action is intended to address the identified unsafe condition.
95-06-05: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 737-200 and -300 series airplanes. This action requires inspections to detect cracking of the fuselage frames at certain locations below the lower jamb of the upper deck main cargo door, and repair, if necessary. This amendment is prompted by reports of fatigue cracking in the fuselage frames at these locations. The actions specified in this AD are intended to prevent rapid decompression of the airplane due to fatigue cracking in the fuselage frames of the main deck cargo door.
2008-08-04: The FAA is superseding an existing airworthiness directive (AD), which applies to certain Airbus Model A318, A319, A320, and A321 airplanes. That AD currently requires repetitive inspections 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 optional terminating actions for certain airplanes, as well as other optional methods for complying with the inspection requirements of the existing AD. This new AD continues to require repetitive inspections for cracking in the forward lug of the support rib 5 fitting of the left and right MLG at new repetitive intervals in accordance with new service information, and repair or replacement of any cracked MLG fitting if necessary. This new AD also requires modification of the rib bushings of the left and right MLG, which would end the repetitive inspections. This AD results from cracks found in the forward lug of the MLG support rib 5 fitting.We are issuing this AD to prevent 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.
2020-12-12: The FAA is adopting a new airworthiness directive (AD) for all Yabor(atilde) Ind(uacute)stria Aeron(aacute)utica S.A. Model ERJ 170 airplanes and Model ERJ 190-100 STD, -100 LR, -100 ECJ, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes. This AD was prompted by reports of cracks discovered on the engine pylon inboard lower link lugs. This AD requires repetitive detailed inspections of the engine inboard and outboard engine pylon lower link lugs for cracking, and repair if necessary, as specified in an Ag(ecirc)ncia Nacional de Avia(ccedil)(atilde)o Civil (ANAC) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
2001-15-25: This amendment adopts a new airworthiness directive (AD), applicable to certain Raytheon Model Hawker 800XP series airplanes and certain Model Hawker 800 (U-125A military) airplanes, that requires a one-time inspection of an attachment bolt in the main landing gear (MLG) door system to determine whether the bolt's protruding threads have been peened; and corrective action, if necessary. The actions specified by this AD are intended to prevent the disconnection of the retaining hook (which holds the MLG door up and locked) from its means of actuation, which could result in a gear-up landing and possible injury to passengers and crew. This action is intended to address the identified unsafe condition.
95-06-07: This amendment supersedes an existing airworthiness directive (AD), applicable to Robinson Helicopter Company (RHC) Model R22 helicopters, that currently requires an initial dye penetrant inspection of the main rotor drive forward flexplate (flexplate), and repetitive visual inspections of certain installed flexplates. This amendment is prompted by three accidents reported by the airworthiness authority of Australia involving failure of the flexplate, located between the main rotor gearbox and clutch assembly. The actions specified by this AD are intended to prevent failure of the flexplate, failure of the main rotor drive system, and subsequent loss of control of the helicopter.
2008-08-01: The FAA is superseding three existing airworthiness directives (ADs) for McCauley Propeller Systems propeller models B5JFR36C1101/ 114GCA-0, C5JFR36C1102/L114GCA-0, B5JFR36C1103/114HCA-0, and C5JFR36C1104/L114HCA-0. Those ADs currently require fluorescent penetrant inspections (FPI) and eddy current inspections (ECI) of propeller blades for cracks, and if any crack indications are found, removing the blade from service. This AD requires the same initial inspections, but extends the compliance times and intervals, adds repetitive inspections, and mandates a life limit for the blades. This AD results from our determination that we must require repetitive inspections for cracks, and from reports of blunt leading edges of the propeller blades due to erosion. We are issuing this AD to detect cracks in the propeller blade that could cause failure and separation of the propeller blade and loss of control of the airplane, and to detect blunt leading edges on the propeller blades, which could cause airplane single engine climb performance degradation and could result in an increased risk of collision with terrain.
2001-15-32: This amendment adopts a new airworthiness directive (AD), applicable to certain Fokker Model F27 Mark 050 series airplanes. This action requires installation of a filler plate and a doubler to reinforce the area under the top antenna for the Traffic Collision Avoidance System (TCAS). This action is necessary to prevent cracking due to fatigue in the area under the antenna for the TCAS, which could result in reduced structural capability of the airplane. This action is intended to address the identified unsafe condition.
2020-13-08: The FAA is superseding Airworthiness Directive (AD) 2005-23-09 for all General Electric Company (GE) CF6-80E1A1, -80E1A2, -80E1A3, - 80E1A4, and -80E1A4/B model turbofan engines. AD 2005-23-09 required initial and repetitive fluorescent-penetrant inspections (FPI) of certain areas of high-pressure compressor (HPC) cases, part number (P/ N) 1509M97G07 and P/N 2083M69G03. This AD requires an update of the Airworthiness Limitations Section (ALS) of GE Engine Manual GEK99376 and the operator's existing continuous airworthiness maintenance program (CAMP). This AD was prompted by GE performed an updated lifing analysis on the HPC case. As a result, GE found additional locations on the cases requiring FPI, revised the inspection interval for performing FPI of the existing location, and added an additional P/N HPC case that requires inspection. The FAA is issuing this AD to address the unsafe condition on these products.
