Compliance: Required as indicated, unless already accomplished. To preclude the possibility of propeller governor failure, accomplish the following: 1) Unless previously accomplished, prior to further flight, drain the Rust Ban Preservative Oil installed by the airplane manufacturer and refill with SAE 30 or SAE 50 straight mineral oil or the type and grade of oil recommended by the engine manufacturer. 2) If the airplane has less than 25 hours' total time in service, prior to further flight, remove the propeller governor and replace with a new or serviceable P/N A210490 propeller governor. 3) Aircraft may be flown to a place where the AD can be accomplished in accordance with FAR 21.197 providing the propeller governor is found to govern engine RPM properly during pre-flight runup. Beechcraft Service Instruction No. 0765-254 pertains to this subject. This amendment becomes effective October 3, 1975, to all persons except those to whom it was made effective earlier by air mail letter issued September 15, 1975.
2015-06-07: We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-100, 737-200, 737-200C, 737-300, 737-400, and 737-500 series airplanes. This AD was prompted by reports of cracking in the lower corners of the forward entry doorway and the upper corners of the airstairs cutout. This AD requires inspections for cracking of the forward entry doorway and airstairs cutout, and corrective actions if necessary. This AD also provides terminating action for the repetitive inspections. We are issuing this AD to detect and correct cracks in the lower corners of the forward entry door cutout and the upper corners of the airstairs cutout, which could progress and result in an inability to maintain cabin pressurization.
2015-06-05: We are adopting a new airworthiness directive (AD) for all Airbus Model A300 and A310 series airplanes, and certain Model A300 B4- 600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes). This AD was prompted by a review of certain repairs, which revealed that the structural integrity of the airplane could be negatively affected if those repairs are not re-worked. This AD requires an inspection to identify certain repairs, and corrective action if necessary. We are issuing this AD to detect and correct certain repairs on the floor cross beams flange. If those repairs are not reworked, the structural integrity of the airplane could be negatively affected.
76-02-07: 76-02-07 PRESTOLITE: Amendment 39-2500. Applies to Prestolite ALV-9400 through ALV-9410 series gear driven alternators. For aircraft having Prestolite ALV-9400 through ALV-9410 series alternators with more than 100 hours time in service compliance is required within the next 25 hours time in service after the effective date of this AD unless already accomplished within the last 75 hours time in service, and thereafter at intervals not to exceed 100 hours time in service from the last check. To detect defective alternator slip ring end bearings and minimize the probability of in-service failures, accomplish the following: Remove the slip ring end bearing cover by using a small sharp chisel, knife blade, or screwdriver to pry it out of the alternator slip ring head. Care must be taken not to damage the end head or bearing cover. If the bearing cover is damaged during removal it must be replaced. Without further disassembly visually inspect the bearing and shaftend for discoloration or any sign of overheating or wear. Pay particular attention to the bearing inner and outer race. If there is any sign of overheating or an indication that the rotor shaft has been turning in the inner race or the outer race has been turning in the end head, the alternator must be removed and repaired. If the rotor shaft has been turning in the bearing inner race, the rotor and bearing must be replaced. If the bearing outer race has been turning in the end head, the bearing and end head must be replaced. Check the bearing grease for any sign of overheating or contamination such as dirt, or metal filings. If the grease is a dark brown or black color, or is so contaminated, the alternator must be removed and the bearing replaced. If the bearing shows no sign of discoloration, overheating, wear, or contamination, the bearing only (not the entire cavity) should be filled with Chevron BRB#2 or Chevron SRI#2 grease or an equivalent approved by Chief, Engineering and Manufacturing Branch, Great Lakes Region. At this time we are not aware of an equivalent lubricant for this application. NOTE: Refer to Continental Service Bulletin No. TCM M75-30 for further information concerning this subject. The checks required by this AD may be performed by the pilot. Operators who have not kept records of hours time in service on individual alternators shall substitute aircraft hours time in service in lieu thereof. This amendment becomes effective February 2, 1976.
2015-05-02: We are superseding Airworthiness Directive (AD) 2014-23-15 for all Airbus Model A318, A319, A320, and A321 series airplanes. AD 2014- 23-15 required revising the maintenance or inspection program to incorporate new, more restrictive airworthiness limitations. This new AD retains the requirement to revise the maintenance or inspection program and removes a conflicting requirement. This AD was prompted by a determination that certain limitations required by AD 2014-23-15 conflict with limitations required by another AD. We are issuing this AD to prevent fatigue cracking, accidental damage, or corrosion in principal structural elements, and possible failure of certain life limited parts, which could result in reduced structural integrity of the airplane.
2015-04-08: We are superseding Airworthiness Directive (AD) 2014-06-08 for certain Bombardier, Inc. Model DHC-8-100, -200, and -300 series airplanes. AD 2014-06-08 required repetitive functional checks of the nose and main landing gear, and corrective actions if necessary; and also provided optional terminating action modification for the repetitive functional checks. This new AD requires a terminating action modification. This AD was prompted by a report that the emergency downlock indication system (EDIS) had given a false landing gear down- and-locked indication and a determination that a terminating action modification is necessary to address the identified unsafe condition. We are issuing this AD to detect and correct a false down-and-locked landing gear indication, which, on landing, could result in possible collapse of the landing gear.
2015-06-02: We are adopting a new airworthiness directive (AD) for GA 8 Airvan (Pty) Ltd Model GA8-TC320 airplanes. This AD results from [[Page 14811]] 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 missing required engine mount fire seal washers, which could reduce the engine retention capability in the event of a fire. We are issuing this AD to require actions to address the unsafe condition on these products.
