2020-17-05: The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Deutschland GmbH Model MBB-BK 117 D-2 helicopters. This AD was prompted by the discovery that certain longitudinal trim actuators, lateral trim actuators, and yaw trim actuators, which are certified for installation on MBB-BK 117 C-2 helicopters, were erroneously listed as eligible for installation on MBB-BK 117 D-2 helicopters. This AD requires removing the affected parts from service and prohibits installing the affected parts on MBB- BK 117 D-2 helicopters. The FAA is issuing this AD to address the unsafe condition on these products.
68-08-07: 68-08-07 LOCKHEED: Amendment 39-585. Applies to Model 1329 Airplanes, Serial Numbers 5001 through 5092, 5094 through 5096. Compliance required as indicated. Recent calibration of several airplanes has revealed a difference in the airspeed and altimeter system static position error from the values presented in the AFM. These differences are in excess of tolerances which can be accepted as normal deviation from an Airplane Flight Manual calibration curve. To detect similar discrepancies, the following is required unless the system has previously been calibrated in accordance with the referenced manufacturer's instructions. Within the next 100 hours' time in service after the effective date of this AD, calibrate the pitot static system in accordance with the instructions given in Lockheed-Georgia Service Bulletin 329-250, Section 2a through 2p, or later FAA approved revision; or in an equivalent manner approved by the Chief, Engineering and Manufacturing Branch, FAA Southern Region. This amendment becomes effective April 19, 1968.
48-06-03: 48-06-03 NAVION: Applies to All models Equipped With Hartzell Propeller Blade Models 8428, 8428C, 8428R Having Serial Numbers Below 61000. Compliance required by April 15, 1948. Examine all Model 8428, 8428C, and 8428R blades having Serial Numbers below 61000 in bright daylight or strong artificial light on the front face in the area approximately 4 inches outboard of the blade clamp. Any fillers used in the blade will be discernible to the naked eye. If fillers are found in this area, the paint should be carefully removed and the fillers removed from the blade. Defects that can be eliminated by removing material to form a shallow saucer not over 1/8 inch at its deepest point, 3/8 inch in width overall, and 1 inch in length overall, should be repaired. Following removal of the defects, the area from which paint has been removed should be repainted and the propeller rebalanced before being returned to service. Blades having defects that cannot be repaired by the above methodor by methods described in the applicable portions of CAM 18, should be returned to the propeller manufacturer. The exact location and the extent of rework necessary to remove any defect should be recorded in the log book. Areas having maximum material removed may not have additional material removed for subsequent injuries.
2002-11-05 R1: The FAA is adopting a new airworthiness directive (AD) to revise AD 2002-11-05, which applies to certain Air Tractor, Inc. (Air Tractor) AT-400 series and Models AT-501, AT-802, and AT-802A airplanes. AD 2002-11-05 establishes a safe life for the wing lower spar cap. Since we issued AD 2002-11-05, we have received reports of cracks found prior to the established safe life on AT-400 series airplanes and on Model AT-802A airplanes. We are issuing separate AD actions for AT-400 series and Models AT-802 and AT-802A airplanes to address the unsafe condition of those airplanes. This AD retains the actions required in AD 2002-11-05 for Model AT-501 airplanes and removes AT-400 series and Models AT-802 and AT-802A airplanes from the applicability of AD 2002-11-05.
2003-13-11: The FAA is adopting a new airworthiness directive (AD) for Pratt & Whitney (PW) PW4074, PW4074D, PW4077, PW4077D, PW4090, and PW4090-3 turbofan engines with high pressure compressor (HPC) rear cases, part numbers (P/Ns) 55H425-01, 55H385-01, and 56H396-01 installed. This AD requires initial and repetitive visual or fluorescent penetrant inspections (FPI) of the J flange on the HPC rear case, and removal from service of the rear case based on certain inspection results. This AD is prompted by reports of cracks propagating from bolt holes in the HPC rear case J flange, and reports of high-cycle HPC rear cases exhibiting cracks propagating into the shell wall. The actions specified in this AD are intended to prevent fracturing and rupturing of the HPC rear case, resulting in uncontained engine failure.
2001-24-11: This amendment adopts a new airworthiness directive (AD) that is applicable to all Raytheon Model Beech 400, 400A, and 400T series airplanes, Model Mitsubishi MU-300 airplanes, and Model Beech MU-300-10 airplanes. This action requires revising the Emergency Procedures Section of the Airplane Flight Manual to ensure the flightcrew is advised of in-flight procedures in the event of loss of airspeed indication. Such loss of airspeed indication and the resulting adverse effects on certain connecting systems could result in reduced controllability of the airplane.
2006-10-03: The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A319-100 and A320-200 series airplanes, and Model A320-111 airplanes. This AD requires modifying the wiring to the fuel pump control of the center fuel tank. This AD results from reports that the low-pressure warning for the fuel pumps of the center fuel tank has come on in flight. We are issuing this AD to ensure that the fuel pumps do not run while dry, which could result in a potential ignition source inside the center fuel tank, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.

(c) Install coils P/N H27-958 bearing yellow inspection stamp symbols other than those listed under (b) above or an equivalent approved by Chief, Engineering and Manufacturing Branch, FAA, Southern Region. (d) This airworthiness directive affects only coils with the green plastic covering and does not affect: (1) Taped coils. (2) Those covered in black plastic. (3) Those bearing inspection stamps of any type or color (other than those listed under (b) above). (4) Those bearing no inspection stamp. The compliance time may be adjusted up to a maximum of 10 hours to coincide with aircraft annual or 100-hour scheduled inspections. (American Industrial Sales Bulletin dated November 1, 1968, pertains to this same subject.) Effective May 1, 1969. Revised June 24, 1969.
2020-16-02: The FAA is adopting a new airworthiness directive (AD) for Pilatus Aircraft Ltd. Models PC-6, PC-6/350, PC-6/350-H1, PC-6/350-H2, PC-6/A, PC-6/A-H1, PC-6/A-H2, PC-6/B-H2, PC-6/B1-H2, PC-6/B2-H2, PC-6/ B2-H4, PC-6/C-H2, PC-6/C1-H2, PC-6-H1, and PC-6-H2 airplanes. 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 rudder shaft assemblies with incorrect rivet configurations. The FAA is issuing this AD to address the unsafe condition on these products.
99-19-07: This amendment adopts a new airworthiness directive (AD), applicable to certain Gulfstream American (Frakes Aviation) Model G-73 (Mallard) and G-73T series airplanes, that requires revising the Airplane Flight Manual (AFM) to include requirements for activation of the airframe pneumatic deicing boots. This amendment is prompted by reports of inflight incidents and an accident that occurred in icing conditions where the airframe pneumatic deicing boots were not activated. The actions specified by this AD are intended to ensure that flightcrews activate the pneumatic wing and tail deicing boots at the first signs of ice accumulation. This action will prevent reduced controllability of the aircraft due to adverse aerodynamic effects of ice adhering to the airplane prior to the first deicing cycle.
