Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2018-22278
Type: Proposed Rule
Date: 2018-10-16
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This proposed AD was prompted by reports of cracking in the frame web, frame integral inboard chord, and fail-safe chord on multiple airplanes in multiple locations below the passenger floor, in addition to an evaluation by the design approval holder (DAH) indicating that certain fuselage frame splices are subject to widespread fatigue damage (WFD). This proposed AD would require repetitive inspections of certain fuselage upper frames, side frames, fail-safe chords, inboard chords, frame webs, and stringers; an inspection for the presence of repairs in certain inspections zones and open tooling holes; and applicable on-condition actions. We are proposing this AD to address the unsafe condition on these products.

Airworthiness Directives; Bombardier, Inc., Airplanes
Document Number: 2018-22154
Type: Rule
Date: 2018-10-16
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This AD was prompted by a report of cracking at the fastener holes of the left- hand-side support bracket of the elevator bell crank for the control linkage in the vertical stabilizer. This AD requires an eddy current inspection on certain support brackets of the elevator bell crank for any cracking at the fastener holes, a measurement to confirm that the fastener hole diameters are within tolerance, and replacement with a new support bracket of the elevator bell crank if necessary. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; ATR-GIE Avions de Transport Régional Airplanes
Document Number: 2018-22153
Type: Rule
Date: 2018-10-16
Agency: Federal Aviation Administration, Department of Transportation
We are superseding Airworthiness Directive (AD) 2006-07-26, which applied to all ATR-GIE Avions de Transport R[eacute]gional Model ATR42 airplanes. AD 2006-07-26 required a one-time inspection to detect discrepancies (e.g., cracking, loose/sheared fasteners, distortion) on the left-hand and right-hand wings, of the outer wing box upper skin and upper rib feet, and repair if necessary. Since we issued AD 2006- 07-26, after initial findings had suggested the cracking was isolated to a few airplanes, we received reports of cracking in these same areas on other Model ATR42 airplanes. This AD requires repetitive inspections to detect discrepancies on the left-hand and right-hand wings, of the outer wing box upper skin and upper rib feet, and repair if necessary. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2018-22152
Type: Rule
Date: 2018-10-16
Agency: Federal Aviation Administration, Department of Transportation
We are superseding Airworthiness Directive (AD) 2015-09-07, which applied to all The Boeing Company Model 787 airplanes. AD 2015- 09-07 required a repetitive maintenance task for electrical power deactivation. This AD requires installing new software for the generator control unit (GCU). This AD also removes certain airplanes from the applicability. This AD was prompted by the determination that a Model 787 airplane that has been powered continuously for 248 days can lose all alternating current (AC) electrical power due to the GCUs simultaneously going into failsafe mode. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus SAS Airplanes
Document Number: 2018-22147
Type: Rule
Date: 2018-10-16
Agency: Federal Aviation Administration, Department of Transportation
We are superseding Airworthiness Directive (AD) 2017-16-07, which applied to certain Airbus SAS Model A330-200, A330-200 Freighter, A330-300, A340-500, and A340-600 series airplanes; and Model A340-313 airplanes. AD 2017-16-07 required inspection of the fuselage bulk cargo door frames at specific locations, and corrective action if necessary. This AD requires new inspections of certain attachment holes for residual surface treatment and cracking, and corrective action if necessary; and provides an optional terminating action for the inspections. This AD also revises the applicability to add certain airplanes and remove others. This AD was prompted by a determination that only airplanes having certain manufacturer serial numbers (MSNs) are affected by tartaric sulfuric anodizing (TSA)/chromic acid anodizing (CAA) surface treatment in the door fitting attachment holes, and that airplanes having certain MSNs were excluded. This AD is intended to complete certain mandated programs intended to support the airplane reaching its limit of validity (LOV) of the engineering data that support the established structural maintenance program. We are issuing this AD to address the unsafe condition on these products.

Agency: Federal Aviation Administration, Department of Transportation
We are superseding Airworthiness Directive (AD) 2012-22-10, which applied to certain Bombardier, Inc., Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes, Model CL-600-2D24 (Regional Jet Series 900) airplanes, and Model CL-600-2E25 (Regional Jet Series 1000) airplanes. AD 2012-22-10 required repetitive inspections to determine that cotter pins are installed at affected wing-to-fuselage attachment joints and replacement if necessary. This AD retains the initial inspection of the wing-to-fuselage attachment joints, and removes the repetitive inspections of all but the forward keel beam attachment joint. This AD also changes the repetitive inspection interval for the forward keel beam attachment joint. This AD was prompted by a determination that additional nuts of the forward keel beam attachment joint should be inspected, and that repetitive inspections of certain wing-to-fuselage attachment joints are not necessary. We are issuing this AD to address the unsafe condition on these products.
