98-05-15: This amendment adopts a new airworthiness directive (AD) that applies to SIAI Marchetti, S.r.1 Models SF600 and SF600A airplanes. This action requires revising the FAA-approved Airplane Flight Manual (AFM) to specify procedures that would prohibit flight in severe icing conditions (as determined by certain visual cues), limit or prohibit the use of various flight control devices while in severe icing conditions, and provide the flight crew with recognition cues for, and procedures for exiting from, severe icing conditions. This AD is prompted by the results of a review of the requirements for certification of these airplanes in icing conditions, new information on the icing environment, and icing data provided currently to the flight crew. The actions specified by this AD are intended to minimize the potential hazards associated with operating these airplanes in severe icing conditions by providing more clearly defined procedures and limitations associated with such conditions.
98-05-10: This amendment adopts a new airworthiness directive (AD) that is applicable to Robinson Helicopter Company (Robinson) Model R44 helicopters. This action requires replacing the aluminum elbows that connect the oil cooler lines to the engine accessory case with steel elbows. This amendment is prompted by two reports of cracks that were discovered in aluminum elbows. The actions specified in this AD are intended to prevent failure of either the 45 degree or 90 degree aluminum elbows that connect the oil lines from the oil cooler to the engine accessory case, which would cause loss of engine oil, resulting in an engine failure and a subsequent forced landing.

2012-12-03: We are superseding an existing airworthiness directive (AD) for all Rolls-Royce plc (RR) models RB211-Trent 970-84, 970B-84, 972- 84, 972B-84, 977-84, 977B-84, and 980-84 turbofan engines. That AD currently requires inspecting the intermediate-pressure (IP) shaft rigid coupling splines for wear resulting in rearward movement of the IP turbine. This AD requires the same inspections, and new inspections based on possible changes in wear rate. This AD was prompted by RR identifying wear beyond engine manual limits on the abutment faces of the splines. RR also determined that an additional IP shaft rigid coupling configuration requires inspection. We are issuing this AD to detect wear on the abutment faces of the splines, which could result in loss of disc integrity, an uncontained failure of the engine, and damage to the airplane.
2005-13-39: The FAA is superseding an existing airworthiness directive (AD), which applies to Airbus Model A321 series airplanes. That AD currently requires revising the Limitations section of the airplane flight manual to include an instruction to use Flap 3 for landing when performing an approach in conditions of moderate to severe icing, significant crosswind (i.e., crosswinds greater than 20 knots, gust included), or moderate to severe turbulence. This new AD requires replacing existing elevator and aileron computers (ELACs) with ELACs having either L83 or L91 software, as applicable, which terminates the requirements of the existing AD. This AD also requires a related concurrent action. In addition, this AD revises the applicability by removing airplanes with these ELAC software standards incorporated in production. This AD is prompted by issuance of mandatory continuing airworthiness information by a civil airworthiness authority. We are issuing this AD to prevent roll oscillationsduring approach and landing in certain icing, crosswind, and turbulent conditions, which could result in reduced controllability of the airplane.
75-05-07: 75-05-07 KING RADIO CORPORATION: Amendment 39-2100. Applies to Model KCS-55 Pictorial Navigation System (magnetic stabilized compass) units, specifically the Gyro Model KG-102 ( ), Part Number 060-0011-0, Serial Numbers 1000 to 1999 and all serial numbers preceded by the letter "P" and Indicator Models KI-525 ( ), Part Number 066-3029-00/01, Serial Numbers 1000 to 1999 and all serial numbers preceded by the letter "P". The Model KCS-55 systems may be installed on various types of aircraft. Compliance: Required as indicated, unless already accomplished. A) Within the next 25 hours' time in service after the effective date of this AD, check the aircraft compass system installed or the aircraft permanent maintenance record to determine if the KCS-55 pictorial navigation system is installed on the aircraft. B) If, as a result of determination required in Paragraph A of this AD, a KCS-55 pictorial navigation system is installed, check the indicator KI-525 ( ) to determineif the serial number falls within those noted in the applicability statement and if the unit has been modified and identified as Mod 1. Also, check the KG 102 gyro and determine if the serial number falls within those noted in the applicability statement and that the unit has been modified and identified as Mod 6. If both units are so identified with the modification number, make an appropriate entry in the aircraft records indicating compliance with this AD. C) If as a result of the determinations required by Paragraphs A and B of this AD unmodified KCS-55 Pictorial Navigation System units are installed, prior to further flight, install a placard on the instrument panel in clear view of the pilot which indicates: "KCS-55 PICTORIAL NAVIGATION SYSTEM IS NOT TO BE USED FOR PRIMARY HEADING OR IFR FLIGHT IF IT IS SOLE GYROSCOPIC HEADING SOURCE" and operate the aircraft in accordance with this limitation. D) On or before November 15, 1975, replace any KCS-55 pictorial navigation system units which fall within the Part Number and Serial Number designations set forth in the applicability statement with modified units which are identified in accordance with King Alert Service Bulletins KI 525-1 and KG 102-6 dated January 2, 1975, or subsequent revisions, as Mod 1 and Mod 6 respectively. When this paragraph has been complied with, Paragraph C of this AD is no longer applicable. E) Any alternative means of compliance with this AD must be approved by the Chief, Engineering and Manufacturing Branch, FAA, Central Region. This amendment becomes effective February 28, 1975.

2012-13-03: We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This AD was prompted by a report of a ground fire which was fed by oxygen escaping from a damaged third crew person oxygen line and had started in the vicinity of an electrical panel. This AD requires replacing and changing the routing of the flexible oxygen hose of the third crew person oxygen line and modifying the entrance compartment assembly. We are issuing this AD to prevent the possibility of damage to the third crew person oxygen line and of an oxygen-fed fire in the airplane.
