2001-05-10: This amendment adopts a new airworthiness directive (AD), applicable to all McDonnell Douglas Model DC-10 and MD-11 series airplanes, and KC-10A (military) airplanes, that requires installation of thrust reverser interlocks on certain airplanes, inspections of the thrust reverser systems to detect discrepancies on certain other airplanes, and corrective actions, if necessary. This amendment is prompted by a determination that the current thrust reverser systems do not adequately preclude unwanted deployment of a thrust reverser. The actions specified by this AD are intended to prevent unwanted deployment of a thrust reverser, which could result in reduced controllability of the airplane.
79-07-02: 79-07-02 ESB WISCO, INCORPORATED: Amendment 39-3442. EXIDE AC 78M and WILLARD W 78M BATTERIES. Applies to those batteries manufactured during December 1978, January and February 1979, identified by the figures N-8, A-9, or B-9 stamped on either terminal post. They may be installed in, but not limited to, the following aircraft: Aero Commander 1960 on - various models, Bellanca 1959 on - various models, Callair 1964 on - various models, Champion 7 series models: 7GC, 7HC, etc., Enstrom F-28 series, possible other models, Helio All series, Lake Amphibian Model C-1 and LA-4, Navion Rangemaster and others, Piper Cherokee and Pawnee PA-28 and PA-25, but not limited to these models, Rockwell All models, Stinson All models, Wing Derringer models. Compliance is required as follows. Remove from service before next flight and replace with any approved battery of comparable rating. This amendment becomes effective April 3, 1979.
2007-17-02: We are adopting a new airworthiness directive (AD) to supersede AD 82-07-04, which applies to certain Allied Ag Cat Productions, Inc. (Ag Cat) G-164 series airplanes. AD 82-07-04 currently requires you to modify the fuel shut-off valve control by installing a new stop-plate. Since we issued AD 82-07-04, we have determined the need to add airplane models and serial numbers that were not previously included in the Applicability section. Consequently, this AD retains the actions of AD 82-07-04 and adds airplane models and serial numbers to the Applicability section. We are issuing this AD to prevent turning the fuel shut-off valve clockwise past the "ON'' position stop which, if not corrected, could allow the fuel valve to be rotated to an unplacarded "OFF'' position. This condition could lead to reduced fuel flow and consequent loss of engine power.
2019-18-03: The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 737 series airplanes, excluding Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This AD requires revising the existing maintenance or inspection program to remove text that allows the size of the thrust reverser upper locking actuator lock sensor target to be changed, and, for certain airplanes, performing repetitive integrity tests of the thrust reverser upper locking actuator. This AD was prompted by a report indicating that alteration of thrust reverser upper locking actuators in accordance with certain data in the Boeing aircraft maintenance manual (AMM) could delay or prevent detection of the failure of the locking mechanism of a thrust reverser upper locking actuator. The FAA is issuing this AD to address the unsafe condition on these products.
2001-05-09: This amendment adopts a new airworthiness directive (AD) for Bell Helicopter Textron Canada (BHTC) Model 430 helicopters that requires modifying the electrical system. This amendment is prompted by the loss of electrical power due to design deficiencies discovered during single-pilot Instrument Flight Rules (IFR) flight testing. The actions specified by this AD are intended to prevent loss of electrical power and subsequent loss of control of the helicopter.
79-02-02: 79-02-02 PIPER AIRCRAFT CORPORATION: Amendment 39-3398. Applies to Model PA-44-180, serial numbers 44-7995001 through 44-7995003, 44-7995005 through 44-7995023, 44-7995025 through 44-7995053, 44-7995055 through 44-7995064, 44-7995066, 67, 69, 71, 73, and 74 airplanes certificated in all categories. Compliance is required within the next 10 hours' time in service after the effective date of this AD unless already accomplished. To prevent fuel leakage due to a damaged fuel line, accomplish the following: (a) Remove the inspection plate (or plates) on the underside of the left and right wings, in the area of the electric fuel boost pump, inboard of the engine nacelle. (b) Inspect the fuel supply lines part number 86238-03 (Left and Right), where the line passes through the rib lightening hole, for damage due to interference with the hole flange. If a fuel supply line is damaged, replace it with a serviceable line. (c) Install a caterpillar grommet, part number 63976-34 (MS21266-1N) on the lower half of the rib lightening hole flange in both wings using a suitable cement to retain the grommet in position. (d) Position the fuel supply line to obtain a minimum clearance of .125 inch from the caterpillar grommet. (e) Reinstall the inspection plates on the left and right wings. (f) Make an appropriate maintenance record entry. (g) An alternate method of compliance may be approved by the Chief, Engineering and Manufacturing Branch, Federal Aviation Administration, Southern Region. NOTE: Piper Service Bulletin; 627, dated October 24, 1978, pertains to this subject. This amendment becomes effective January 24, 1979.
2007-16-15: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated 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: Cracks have been evidenced on the nose landing gear LH (left- hand) and RH (right-hand) hinge fittings due to stress corrosion on in-service aircraft. If undetected, they could lead to complete rupture of one or two of the fittings. The unsafe condition is collapse of the nose landing gear. We are issuing this AD to require actions to correct the unsafe condition on these products.
2001-05-07: This amendment supersedes airworthiness directive (AD) 2000-25-06, dated December 5, 2000, that is applicable to certain Pratt & Whitney (PW) PW4000 turbofan engines with the current design low pressure turbine (LPT) 4th stage air seal installed. That AD currently requires, based on engine model, replacement of the current design seal with a new design seal, or with a modified seal. This amendment adds the listing of certain engine serial numbers, to correct an error in the applicability section of AD 2000-25-06, for engines affected by PW Service Bulletin (SB) PW4 ENG 72-657, Revision 1, dated July, 19, 2000. This correction is prompted by comments received on AD 2000-25-06. The actions specified by this AD are intended to reduce stresses that could lead to LPT 4th stage air seal cracking, resulting in seal fracture, uncontained engine failure, and damage to the airplane.
2019-17-06: The FAA is adopting a new airworthiness directive (AD) for all Fokker Services B.V. Model F28 Mark 0070 and 0100 airplanes. This AD was prompted by reports of cracks on certain nose landing gear (NLG) turning tubes resulting from incorrectly applied repairs. This AD requires removing the affected parts and replacing them with serviceable parts. The FAA is issuing this AD to address the unsafe condition on these products.
2007-16-02: 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 airworthiness authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as keel beam rupture, which affects the structural integrity of the area. We are issuing this AD to require actions to correct the unsafe condition on these products.
