Airworthiness Directives; Airbus Airplanes Republication
Document Number: R1-2018-09280
Type: Rule
Date: 2018-05-15
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Airbus Model A318 series airplanes and Model A319 series airplanes; all Model A320-211, -212, -214, -216, -231, -232, and -233 airplanes; and all Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. This AD was prompted by an evaluation by the design approval holder (DAH) indicating that the holes of the upper cleat to upper stringer attachments at certain areas of the left- and right-hand wings are subject to widespread fatigue damage (WFD). This AD requires modifying the holes of the upper cleat to upper stringer attachments at certain areas of the left- and right-hand wings. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2018-10299
Type: Proposed Rule
Date: 2018-05-15
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede Airworthiness Directive (AD) 2010-25- 06, which applies to certain The Boeing Company Model 737-200, -300, - 400, and -500 series airplanes. AD 2010-25-06 requires repetitive inspections for cracking of certain fuselage frames and stub beams, and corrective actions if necessary. AD 2010-25-06 also provides for an optional repair, which terminates the repetitive inspections. For airplanes on which a certain repair is done, AD 2010-25-06 also requires repetitive inspections for cracking of certain fuselage frames and stub beams, and corrective actions if necessary. Since we issued AD 2010-25-06, additional cracking was found in areas not covered by the inspections. This proposed AD would retain the actions required by AD 2010-25-06 and would expand the inspection area. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Airplanes
Document Number: 2018-10298
Type: Proposed Rule
Date: 2018-05-15
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A319-115 and -132 airplanes, and Model A320-214, - 216, -232, and -233 airplanes. This proposed AD was prompted by a report indicating that certain modified airplanes do not have electrical ground wires on the fuel level sensing control unit (FLSCU), which adversely affects the fuel gravity feeding operation. This proposed AD would require modification of the FLSCU wiring. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Airplanes
Document Number: 2018-10214
Type: Rule
Date: 2018-05-15
Agency: Federal Aviation Administration, Department of Transportation
We are superseding Airworthiness Directive (AD) 2016-23-01, which applied to all Airbus Model A310 series airplanes. AD 2016-23-01 required repetitive detailed inspections for cracking around the fastener holes in certain areas of the wing top skin panels, supplemental repetitive ultrasonic inspections for cracking around the fastener holes in certain other areas of the wing top skin panels, and repair if necessary. This AD adds an inspection and modification of the fastener holes of the wing top skin panels at a certain area. This AD also includes terminating action for certain inspections. This AD was prompted by an evaluation by the design approval holder (DAH) which indicates that the wing top skin panel fastener holes at a certain area are also subject to widespread fatigue damage (WFD). We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2018-10213
Type: Proposed Rule
Date: 2018-05-15
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede Airworthiness Directive (AD) 2017-16- 05, which applies to certain The Boeing Company Model 737-600, -700, - 700C, -800, -900, and -900ER series airplanes. AD 2017-16-05 requires a one-time detailed visual inspection for discrepancies in the Krueger flap bullnose attachment hardware, and related investigative and corrective actions if necessary. Since we issued AD 2017-16-05, we received a report of a missing no. 2 Krueger flap bullnose hinge bolt from an airplane that was not included in the applicability of AD 2017- 16-05. This proposed AD would add airplanes and an additional inspection to determine if any Krueger flap no. 1, 2, 3, or 4 has been replaced, and related investigative and corrective actions. Since this is a rotable parts issue, the applicability of this AD has been expanded beyond the airplanes listed in the related service bulletin to include all airplanes on which a Krueger flap bullnose may be installed. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus
Document Number: 2018-10211
Type: Proposed Rule
Date: 2018-05-15
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A350-941 airplanes. This proposed AD was prompted by an inspection on the production line that revealed evidence of paint peeling on the forward and aft cargo frame forks around the hook bolt hole. This proposed AD would require a detailed visual inspection for any deficiency of the frame forks around the hook bolt hole on certain forward and aft cargo doors and applicable corrective actions. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2018-10209
Type: Proposed Rule
Date: 2018-05-15
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede Airworthiness Directive (AD) 2016-13- 16, which applies to all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. AD 2016-13-16 requires an inspection or records check to determine if affected horizontal stabilizers are installed, related investigative actions, and, for affected horizontal stabilizers, repetitive inspections for any crack of the horizontal stabilizer rear spar upper chord, and corrective action if necessary. Since we issued AD 2016-13-16, we have determined that clarification of inspection areas and serial number information of the horizontal stabilizer is necessary. Therefore, this proposed AD would retain the requirements of AD 2016-13-16, with revised service information that clarifies the inspection areas and serial number information of the horizontal stabilizer. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Pacific Aerospace Limited Airplanes
Document Number: 2018-10025
Type: Rule
Date: 2018-05-15
Agency: Federal Aviation Administration, Department of Transportation
We are superseding Airworthiness Directive (AD) 2018-03-15 for Pacific Aerospace Limited Model 750XL airplanes. 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 reports of finding abrasion damage behind the instrument panel caused by ventilation hose chafing. We are issuing this AD to require actions to address the unsafe condition on these products.

We are issuing this AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2018-09865
Type: Rule
Date: 2018-05-15
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-200B, 747-300, and 747-400 series airplanes. This AD requires replacing certain low-pressure oxygen flex- hoses with new non-conductive low-pressure oxygen flex-hoses in the gaseous passenger oxygen system in airplanes equipped with therapeutic oxygen. This AD also requires a general visual inspection of the low- pressure passenger oxygen system to ensure there is minimum clearance of the oxygen system components from adjacent structure and systems. This AD was prompted by reports of low-pressure flex-hoses of the flightcrew oxygen system that burned through due to inadvertent electrical current from a short circuit. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2018-09864
Type: Rule
Date: 2018-05-15
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This AD was prompted by reports indicating additional cracking in the inspar upper skin at wing buttock line (WBL) 157 and in the skin at two holes common to the rear spar in the same area, and rear spar web cracks were also noted on both wings. Subsequent inspections revealed that the right rear spar upper chord was almost completely severed and the left rear spar upper chord was completely severed. Additional reports identified cracking in the main landing gear (MLG) beam forward support fitting. This AD requires the installation of standard-size fasteners for a certain configuration and inspections for any crack in certain locations of the rear spar. We are issuing this AD to address the unsafe condition on these products.
