2006-09-12: The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A300-600, A310-200, and A310-300 series airplanes. This AD requires modifying the forward outflow valve of the pressure regulation subsystem. This AD results from a report of accidents resulting in injuries occurring on in-service airplanes when crewmembers forcibly initiated opening of passenger/crew doors against residual pressure, causing the doors to rapidly open. In these accidents, the buildup of residual pressure in the cabin was caused by the blockage of the outflow valve by an insulation blanket. We are issuing this AD to prevent an insulation blanket or other debris from being ingested into and jamming the forward outflow valve of the pressure regulation subsystem, which could lead to the inability to control cabin pressurization and adversely affect continued safe flight of the airplane.
95-26-13: This amendment supersedes Airworthiness Directive (AD) 76-25-06, which currently requires replacing oil cooler hoses on The New Piper Aircraft, Inc. (Piper) Model PA28-140 airplanes, and inspecting for a minimum clearance between the oil cooler hose assemblies and the front exhaust stacks and adjusting if proper clearance is not obtained. This action maintains the clearance inspection and oil cooler hose replacements, requires this inspection and these replacements to be repetitive, and extends the applicability to include PA32 series and other PA28 series airplanes. It also provides the option of installing approved TSO-C53a, Type D oil cooler hose assemblies as terminating action for the repetitive inspection requirement. Numerous incidents/accidents caused by oil cooler hose rupture or failure on the affected airplanes prompted this action. The actions specified by this AD are intended to prevent these oil cooler hoses from failing or rupturing, which could result in engine stoppage and subsequent loss of control of the airplane.
99-01-19: This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A320 series airplanes, that requires repetitive inspections to detect fatigue cracking in certain areas of the fuselage; and corrective action, if necessary. This amendment also provides for an optional terminating action for the repetitive inspections.

2019-01-03: We are superseding Airworthiness Directive (AD) 2016-18-01, which applied to certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. AD 2016-18-01 required repetitive lubrication of the forward and aft trunnion pin assemblies of the right and left main landing gears (MLGs); repetitive inspection of these assemblies for corrosion and chrome damage, and related investigative and corrective actions if necessary; and installation of \n\n((Page 3291)) \n\nnew or modified trunnion pin assembly components, which terminated the repetitive lubrication and repetitive inspections. Since we issued AD 2016-18-01, we have determined that rotable parts were not addressed in that AD, and it is therefore necessary to include all airplanes of the affected models in the applicability. This AD retains the requirements of AD 2016-18-01, adds airplanes to the applicability, and prohibits the installation of a MLG or MLG trunnion pin assembly under certain conditions. We are issuing this AD to address the unsafe condition on these products.

Box 3707, Seattle, Washington 98124-2207. This service bulletin may be examined at the FAA, Northwest Mountain Region, 17900 Pacific Highway South, Seattle, Washington, or the Seattle Aircraft Certification Office, 9010 East Marginal Way South, Seattle, Washington. \n\n\tThis amendment becomes effective April 11, 1986.
2018-23-04: We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model DHC-8-102, -103, and -106 airplanes; Model DHC- 8-200 series airplanes; and Model DHC-8-300 series airplanes. This AD was prompted by a report that a certain modification to the auto relight system is incompatible with a certain beta lockout system modification and could result in de-activation of the auto ignition feature of the No. 2 engine. This AD requires an inspection of the auto ignition system and applicable rectification. We are issuing this AD to address the unsafe condition on these products.
97-06-10: This amendment supersedes Airworthiness Directive (AD) 91-14-14, which currently requires repetitively inspecting the main landing gear (MLG) "A" frame assemblies for cracks on Raytheon Aircraft Company (Raytheon) Model 76 airplanes (formerly referred to as Beech Model 76 airplanes), and replacing any assembly found cracked. AD 91-14-14 resulted from reports of fatigue cracks developing on the MLG "A" frame assemblies of the affected airplanes. Raytheon has developed improved design MLG "A" frame assemblies, and the Federal Aviation Administration (FAA) has determined that Model 76 airplanes with an improved design "A" frame assembly installed on both the left and right MLG should be exempt from AD 91-14-14. This action retains the requirement of repetitively inspecting the MLG "A" frame assemblies for cracks and replacing any cracked "A" frame assembly only for those Model 76 airplanes that do not have the improved design parts installed. The actions specified by this ADare intended to prevent MLG failure because of a cracked "A" frame assembly, which could result in loss of control of the airplane during landing operations.
2019-02-04: We are superseding Airworthiness Directive (AD) 2018-22-05, which applied to Engine Alliance (EA) GP7270, GP7272, and GP7277 turbofan engines with a certain high-pressure turbine (HPT) case installed. AD 2018-22-05 required removal of affected HPT stator cases (HPT cases) from service and their replacement with a part eligible for installation. This AD retains these requirements, reduces the compliance times for the removal and replacement of certain HPT cases, and identifies additional affected parts that must be removed and replaced. This AD was prompted by the discovery of a quality escape at a manufacturing facility involving unapproved welds on HPT cases. Subsequent additional findings suggested the need for an updated risk analysis, resulting in reduced compliance times for those parts and the identification of additional affected parts. We are issuing this AD to address the unsafe condition on these products.
98-21-02: This amendment supersedes an existing airworthiness directive (AD), applicable to certain Fokker Model F27 Mark 100, 200, 300, 400, 500, 600, and 700 Rough Field Version (RFV) series airplanes, that currently requires inspection of the main landing gear (MLG) legs to determine if parts are missing or damaged, and modification, if necessary; and periodic measurements of the extension of each MLG shock absorber sliding member. That AD also provides for the accomplishment of a certain modification as optional terminating action for the periodic measurements. This amendment requires accomplishment of the previously optional terminating action, and revises the applicability of the existing AD to add an airplane model. 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 loss of the MLG sliding member, which could result in reduced structural integrity of the MLG.
2019-02-01: We are superseding Airworthiness Directive (AD) 2018-16-07, which applied to certain General Electric Company (GE) GEnx turbofan engines. AD 2018-16-07 required removal and replacement of affected high-pressure turbine (HPT) stator cases (HPT cases). This AD retains those requirements, but reduces certain compliance times. This AD was prompted by the discovery of a quality escape at a manufacturing facility and a determination that the compliance time for the removal and replacement of certain HPT cases must be reduced. We are issuing this AD to address the unsafe condition on these products.
