2015-07-07: We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 777-200, -200LR, -300ER, and 777F series airplanes. This AD was prompted by a report of a jettison fuel pump that was shut off by the automatic shutoff system during the center tank fuel scavenge process on a short-range flight and a subsequent failure analysis of the fuel scavenge system. This AD requires making wiring changes, modifying certain power panels, installing electrical load management system 2 (ELMS2) software, and accomplishing a functional test. We are issuing this AD to prevent extended dry running of the jettison fuel pumps, which can be a potential ignition source inside the main fuel tanks, and consequent fuel tank fire or explosion in the event that the jettison pump overheats or has an electrical fault.
2015-07-04: We are adopting a new airworthiness directive (AD) for PILATUS Aircraft Ltd. Model PC-7 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 the potential for a spring on the air conditioning compressor clutch plate to shear the oil cooler inlet-hose due to the close routing of these parts without a protective cover. We are issuing this AD to require actions to address the unsafe condition on these products.
2005-19-04: The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A340-200 and -300 series airplanes. This AD requires revising the airplane flight manual to incorporate new procedures for the flightcrew to follow to correct miscalculation of the takeoff and accelerating or stopping distance of the airplane during a ferry flight under certain conditions. This AD results from a report that a software error could result in a miscalculation (underestimation) of the runway length necessary for takeoff in the case of a ferry flight with one engine not operating. We are issuing this AD to prevent this miscalculation, which, if combined with high takeoff weight, too-short runway length, and high altitude and temperature of the airport, could result in inability of the flightcrew to abort the takeoff in a safe manner, reduced controllability of the airplane, and runway overrun.
2015-06-06: We are adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model 4101 airplanes. This AD was prompted by a report of the failure, due to overheat, of a bracket on which the earth post (EP) for the generator and propeller de-ice systems is located. This AD requires an inspection of the affected EPs and attachment structure for damage, an inspection of the earth cables of the generator and propeller de-ice system for signs of overheating and arcing damage, a torque check of the affected EP stiff nuts, an electrical high current bonding check of the bracket, and corrective actions if necessary. We are issuing this AD to detect and correct an overheat failure of the EPs for the generator and propeller de-ice system, and possible degradation of the wing front spar cap and/or web, which could affect the structural integrity of the wing.
2005-17-13: The FAA is adopting a new airworthiness directive (AD) for all Short Brothers Model SD3-60 airplanes. This AD requires an inspection of the rudder for damage, an inspection of the balance weight attachment for discrepancies, an inspection of the rudder horn spar and cleats for cracking and corrosion, and corrective action if necessary. This AD results from events in which fatigue cracking was found on the rudder horn spar. We are issuing this AD to detect and correct cracking and corrosion of the rudder horn spar, which could lead to detachment of the mass balance weight of the rudder. The detachment of the mass balance weight could jam or restrict the movement of the rudder, which could result in reduced controllability of the airplane. Loss of a mass balance weight could also damage other parts of the airplane, which could result in reduced controllability of the airplane, or could result in an injury to a person or damage to property on the ground.

62-03-03: 62-03-03 NAVION: Amdt. 396 Part 507 Federal Register February 3, 1962. Applies to Navion, Navion A, B, D, E, F, and G Aircraft. Compliance required within the next 25 hours' time in service after the effective date of this AD and at each periodic inspection thereafter. The landing gear selector valve end fitting P/N 145-58145-3 (heat treated and non-heat treated) has a service history of failure during attempts to extend the gear. To preclude further difficulties: Inspect the gear actuating system in accordance with Navion Service Letter No. 81, dated March 31, 1961. Any defective parts found as a result of this inspection must be replaced prior to further flight. This supersedes AD 50-24-01. This directive effective March 6, 1962.
2015-02-02: We are adopting a new airworthiness directive (AD) for certain [[Page 5903]] Bombardier, Inc. Model CL-215-6B11 (CL-215T Variant), and CL-215-6B11 (CL-415 Variant) airplanes. This AD was prompted by a report that, during a routine inspection, corrosion was discovered on the lower bearing of the rudder upper torque tube. This AD requires applying grease to the bearing; doing a general visual inspection of the expelled old grease for any contaminants, metal wear, and indication of corrosion, and replacing the bearing if necessary; and revising the maintenance or inspection program, as applicable, to incorporate the rudder spring tab operational test and a check of the rudder spring tab operation into the daily inspection. We are issuing this AD to prevent corroded bearings, which could result in a partial or total loss of axial support.
