Airworthiness Directives; Saab Model SAAB-Fairchild SF340A (SAAB/SF340A) and SAAB 340B Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated 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:
Airworthiness Directives; Boeing Model 747-100, -100B, -100B SUD, -200B, -200C, -300, -400, and -400D Series Airplanes; and Model 747SR Series Airplanes
The FAA withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD) for certain Boeing Model 747-100, -100B, -100B SUD, -200B, -200C, -300, -400, and -400D series airplanes; and Model 747SR series airplanes. The proposed AD would have required repetitive inspections of the forward corner reveal of the number 3 main entry doors (MEDs) for cracking, and corrective actions if necessary. Since the proposed AD was issued, we have received comments for the NPRM and new data showing other issues related to the unsafe condition. The data include reports that additional airplanes are affected by the identified unsafe condition; and that a ``sharp edge'' detail may be present on certain one-piece machined 6061 aluminum reveals, which could lead to fatigue cracking. We have determined from these data that the corrective actions proposed by the NPRM are inadequate for addressing the identified unsafe condition. We are considering requiring other rulemaking, which provides corrective actions for the identified unsafe condition. Accordingly, the proposed AD is withdrawn.
Airworthiness Directives; Airbus Model A300 Series Airplanes and Model A300-600 Series Airplanes
The FAA is revising an earlier NPRM for an airworthiness directive (AD) that applies to all Airbus Model A300 airplanes; and all Airbus Model A300 B4-601, A300 B4-603, A300 B4-620, A300 B4-622, A300 B4-605R, A300 B4-622R, A300 F4-605R, A300 F4-622R, and A300 C4-605R Variant F airplanes. The original NPRM would have required inspecting to determine the part number of the sliding rods of the main landing gear (MLG) retraction actuators. For MLG retraction actuators equipped with sliding rods having certain part numbers, the original NPRM would also have required inspecting for discrepancies, including but not limited to cracking, of the sliding rod; and performing corrective actions if necessary. The original NPRM resulted from a report of a failure of a sliding rod of the MLG retraction actuator before the actuator reached the life limit established by the manufacturer. This action revises the original NPRM by proposing to require the return of affected sliding rods to the manufacturer. We are proposing this supplemental NPRM to prevent failure of the sliding rod of the MLG retraction actuator, which could result in reduced structural integrity of the MLG.
Airworthiness Directives; McDonnell Douglas Model DC-9-81 (MD-81) and DC-9-82 (MD-82) Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain McDonnell Douglas Model DC-9-81 (MD-81) and DC-9-82 (MD-82) airplanes. This proposed AD would require, for certain airplanes, inspecting for cracking of the fuselage skin at the upper corners of the forward passenger doorjamb, installing or replacing doublers as applicable, and doing applicable repairs. This proposed AD results from reports of fatigue cracking in the fuselage skin at the upper corners of the forward passenger doorjamb. We are proposing this AD to prevent cracking of the fuselage skin at the upper corners of the forward passenger doorjamb, which could lead to loss of overall structural integrity of the airplane.
Airworthiness Directives; GROB-WERKE GMBH & CO KG Models G102 CLUB ASTIR III, G102 CLUB ASTIR IIIb, and G102 STANDARD ASTIR III Gliders
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated 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:
Airworthiness Directives; Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-300, 747-400, 747-400D, and 747SR Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-300, 747-400, 747-400D, and 747SR series airplanes. For certain airplanes, this proposed AD would require a material type inspection to determine if the lower forward corner reveal of the number 3 main entry doors (MEDs) is a casting. If the reveals are castings, this proposed AD would require repetitive inspection of the reveals for cracking, and corrective action if necessary. If the reveals are not castings, this proposed AD would require a detailed inspection of the reveals for a sharp edge and repetitive inspection of the reveals for cracking, and corrective action if necessary. For certain other airplanes, this AD would require only a detailed inspection of the reveals for a sharp edge and repetitive inspection of the reveals for cracking, and corrective action if necessary. For certain other airplanes, this AD would require repetitive inspection of the reveals for cracking only, and corrective action if necessary. This proposed AD results from reports of cracking and/or a sharp edge in the lower forward corner reveal of the number 3 MEDs. We are proposing this AD to detect and correct fatigue cracking of the lower forward corner reveal of the number 3 MEDs, which could lead to the door escape slide departing from the airplane when the door is opened and the slide is deployed, and consequent injuries to passengers and crew using the door escape slide during an emergency evacuation.
Airworthiness Directives; General Electric Company (GE) CF6-80C2 Series and CF6-80E1 Series Turbofan Engines
The FAA proposes to adopt a new airworthiness directive (AD) for GE CF6-80C2 series and CF6-80E1 series turbofan engines. This proposed AD would require installing doubler pads (deflectors) on stage 5 of certain LPT cases, or replacing those LPT cases with LPT cases that have the deflectors already installed. This proposed AD results from four events of hardware fragments, which liberated into the flowpaths and wore through LPT cases on CF6-80C2 and -80E1 series engines. We are proposing this AD to prevent an uncontained release of engine debris and loss of the structural integrity of the mount system that supports the engine. Loss of the mount system structural integrity could result in the engine separating from the airplane.
Aviation Safety Inspector Airport Access
Two rulemakings finalized several years ago removed regulatory language that implemented FAA Aviation Safety Inspector (ASI) statutory authority to access air operations areas, secured areas, and security identification display areas. This proposal reiterates and clarifies the authority of an ASI with the proper credentials to access air operations areas, secured areas, and security identification areas of an airport. The proposal would make sure ASIs have access to these areas of an airport so they can perform official duties in support of the FAA's safety mission.
