2021-12-10: The FAA is adopting a new airworthiness directive (AD) for Leonardo S.p.a. Model AB139 and AW139 helicopters with 3-stretcher kit part number 139084-501 installed. This AD was prompted by a report of a design deficiency which affects the primary stretcher unit of the 3- stretcher kit. This AD requires installing a placard on the primary stretcher. The FAA is issuing this AD to address the unsafe condition on these products.
2018-19-29: We are adopting a new airworthiness directive (AD) for all Airbus SAS Model A330-200 Freighter, -200, and -300 series airplanes; and Airbus SAS Model A340-200, -300, -500, and -600 series airplanes. This AD was prompted by a report of deficient fatigue performance of high strength steel used in forgings. Components made from the affected high strength steel are installed on the main landing gear (MLG), nose landing gear (NLG), and center landing gear (CLG). This AD requires identifying the part number and serial number of certain components installed on the MLG, NLG, and CLG; replacing affected parts; identifying the airplane's weight variant; and determining the applicable life limit for certain components installed on the MLG, NLG, and CLG. We are issuing this AD to address the unsafe condition on these products.
85-23-05: 85-23-05 BELL HELICOPTER TEXTRON, INC.: Letter issued November 8, 1985. Applies to all Bell Helicopter Model 214B and 214ST series helicopters certified in all categories that have collective sleeve part number 214-010-411-001 or -003 with serial number Al9-00001 through Al9-00738 or serial number A-1 through A-10 installed. Compliance is required before further flight after receipt of this AD, unless previously accomplished, and thereafter at 250 hour intervals. To prevent failure of the collective sleeve, accomplish the following: a. Before further flight after receipt of this priority letter AD, perform a magnetic particle inspection of the affected sleeves using the procedures described in Bell Alert Service Bulletin 214-84-26, dated March 12, 1984, or 214ST-84-17, dated March 12, 1984, as appropriate. NOTE: It is essential that the paint and primer be removed as described in the service bulletins prior to performing the magnetic particle inspection.b. Repeat the magnetic particle inspection every 250 hours time in service. c. If cracks are found, replace with serviceable parts. d. An alternative means of compliance or adjustment of the compliance time, which provides an equivalent level of safety, must be approved by the Manager, Helicopter Certification Branch, Aircraft Certification Division, FAA, Southwest Region. This airworthiness directive is effective upon receipt.
2006-22-11: 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 unsatisfactory initial elevator trim actuator greasing, which may lead to the icing of the elevator trim and generate an untrimmed nose-up attitude after an autopilot disconnection. We are issuing this AD to require actions to correct the unsafe condition on these products.
2006-22-02: The FAA is superseding an existing airworthiness directive (AD), which applies to certain Airbus Model A300-600 series airplanes. That AD currently requires an inspection for evidence of chafing between the hydraulic flexible hose and the ram air turbine (RAT) hub, and related investigative and corrective actions if necessary. This new AD extends the applicability to include all Model A300-600 series airplanes that are equipped with a certain RAT. This AD results from reports of holes in the RAT hub cover. We are issuing this AD to prevent a hole in the RAT hub cover. A hole in the RAT hub cover could allow water to enter the RAT governing mechanism, freeze during flight, and jam the governing mechanism. In addition, the metal particles that result from chafing between the hydraulic flexible hose and the RAT could mix with the lubricant grease and degrade the governing mechanism. In an emergency, a jammed or degraded RAT could result in its failure to deploy, loss of hydraulicpressure or electrical power to the airplane, and consequent reduced controllability of the airplane. DATES: This AD becomes effective December 1, 2006. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of December 1, 2006. On August 26, 2005 (70 FR 42267, July 22, 2005), the Director of the Federal Register approved the incorporation by reference of Airbus Service Bulletin A300-29-6054, Revision 01, excluding Appendix 01, dated November 4, 2004.
2018-19-25: We are adopting a new airworthiness directive (AD) for all Dassault Aviation Model FALCON 2000 airplanes. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD requires revising the maintenance or inspection program, as applicable, to incorporate new maintenance requirements and airworthiness limitations. We are issuing this AD to address the unsafe condition on these products.
2006-22-12: The FAA is superseding an existing airworthiness directive (AD) for Hartzell Propeller Inc. model HC-B5MP-3( )/M10282A( )+6 five- bladed propellers. That AD currently requires initial and repetitive torque check inspections on the mounting bolts on certain model Hartzell Propeller Inc. HC-B5MP-3( )/M10282A( )+6 five-bladed propellers, replacement of mounting bolts if necessary, and inspection and resurfacing of the engine and propeller mounting flanges if necessary. This AD requires the same actions but requires more detailed overhaul inspections and maintenance than the previous AD, AD 2004-21- 01. This AD also adds Hartzell Propeller Inc. HC-B5MP-3( )/M10876( )( )( )( ) five-bladed propellers to the applicability. This AD results from reports of fretting wear still occurring between the engine and propeller mounting flanges. The fretting wear results in loss of mounting bolt preload, causing failure of the mounting bolts. We are issuing this AD to prevent propeller separation from the airplane.
2000-10-18: This amendment supersedes an existing airworthiness directive (AD), applicable to certain Airbus Industrie Model A300, A300-600, and A310 series airplanes, that currently requires inspections to detect cracks in the lower spar axis of the pylons between ribs 6 and 7, and repair, if necessary. For certain Model A310 series airplanes, this amendment reduces the currently required inspection thresholds and intervals, and removes an option for a terminating modification. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent such fatigue cracking, which could result in reduced structural integrity of the engine pylon's lower spar, and possible separation of the engine from the airplane.
99-18-04: This amendment adopts a new airworthiness directive (AD), applicable to certain Dornier Model 328-100 series airplanes, that requires repetitive inspections to detect cracking of the support beam of the main landing gear (MLG) fairing, and a permanent repair, if necessary. This AD also requires installation of reinforcement parts for the longitudinal beam of the MLG fairing, which terminates the requirements of this AD. This amendment is prompted by the issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent cracking of the support beam of the MLG fairing, which could result in reduced structural integrity of the lower part of the MLG fairing, and consequent separation of part of the fairing from the airplane and possible damage to the airplane or injury to persons on the ground.
2018-19-21: We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 707 airplanes, and Model 720 and 720B series airplanes. This AD was prompted by fuel system reviews conducted by the manufacturer. This AD requires revising the maintenance or inspection program to include new airworthiness limitations. We are issuing this AD to address the unsafe condition on these products.
