Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2014-12260
Type: Proposed Rule
Date: 2014-05-28
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede Airworthiness Directive (AD) 2010-03- 05, which applies to all The Boeing Company Model 747-200C and -200F series airplanes. AD 2010-03-05 currently requires, for section 41 upper deck floor beam upper chords, an inspection for cracks of certain fastener holes, and corrective action if necessary; and repetitive replacements of the upper chords, straps (or angles), and radius fillers of certain upper deck floor beams and, for any replacement that is done, inspections for cracks, and corrective actions if necessary. Since we issued AD 2010-03-05, we have determined that the upper deck floor beams are subject to widespread fatigue damage (WFD), the existing inspection program is not sufficient to maintain an acceptable level of safety, and section 42 upper deck floor beam upper chords are subject to the unsafe condition. This proposed AD would add post- replacement inspections for section 41 and reduce certain compliance times. This proposed AD would also require repetitive inspections of section 42 upper deck floor beam upper chords, repetitive replacements of the upper chords, post-replacement inspections, and corrective action if necessary. We are proposing this AD to detect and correct cracking of the upper chords and straps (or angles) of the floor beams, which could lead to failure of the floor beams and consequent loss of controllability, rapid decompression, and loss of structural integrity of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2014-12258
Type: Proposed Rule
Date: 2014-05-28
Agency: Federal Aviation Administration, Department of Transportation
The FAA withdraws a notice of proposed rulemaking (NPRM) that would supersede certain existing airworthiness directives (ADs) for The Boeing Company Model 757-200, -200PF, and -200CB series airplanes. The NPRM proposed to require a determination of the type of trailing edge wedges of the leading edge slats, repetitive inspections on certain trailing edge wedges for areas of skin-to-core disbonding, and corrective actions if necessary; and proposed to revise the applicability of the existing ADs to include additional airplanes. The NPRM also provided an optional terminating action for the repetitive inspections. Since we issued the NPRM, we have determined that the manufacturer's service information is inadequate to accomplish the actions necessary to address the unsafe condition. Once the manufacturer has issued new service information to address the unsafe condition, we may issue new rulemaking action that positively addresses the unsafe condition identified in the NPRM. Accordingly, the NPRM is withdrawn.
Airworthiness Directives; Honeywell International Inc. Air Data Pressure Transducers
Document Number: 2014-12256
Type: Proposed Rule
Date: 2014-05-28
Agency: Federal Aviation Administration, Department of Transportation
We propose to rescind airworthiness directive (AD) 2012-26-15, which applies to certain Honeywell International Inc. air data pressure transducers as installed on various aircraft. AD 2012-26-15 requires doing various tests or checks of equipment having certain air data pressure transducers, removing equipment if necessary, and reporting the results of the tests or checks. As an option to the tests or checks, AD 2012-26-15 allows removal of affected equipment having certain air data pressure transducers. We issued AD 2012-26-15 to detect and correct inaccuracies of the pressure sensors, which could result in altitude, computed airspeed, true airspeed, and Mach computation errors. AD 2012-26-15 reported that these errors could reduce the ability of the flightcrew to maintain the safe flight of the aircraft and could result in consequent loss of control of the aircraft. Since we issued AD 2012-26-15, we have received new data indicating that the safety risk is lower than originally estimated.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2014-12254
Type: Proposed Rule
Date: 2014-05-28
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt 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 proposed 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 proposed AD would require inspections for cracking of the forward entry doorway and airstairs cutout, and corrective actions if necessary. This proposed AD also provides terminating action for the repetitive inspections. We are proposing 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.
Airworthiness Directives; Airbus Airplanes
Document Number: 2014-12251
Type: Proposed Rule
Date: 2014-05-28
Agency: Federal Aviation Administration, Department of Transportation
We are revising an earlier proposed airworthiness directive (AD) for all Airbus Model A318, A319, A320, and A321 series airplanes. The NPRM proposed to supersede AD 2011-14-06 and proposed revising the maintenance program. The NPRM was prompted by the determination that more restrictive limitations are necessary. This action revises the NPRM by revising the maintenance program to incorporate new limitations. We are proposing 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. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2014-12244
Type: Proposed Rule
Date: 2014-05-28
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-600 and -700 series airplanes. This proposed AD was prompted by reports of cracking in a bulkhead lower frame. This proposed AD would require a detailed and open hole high frequency eddy current (HFEC) inspection of the left- and right- side lower frame webs and inner chords for cracking, if necessary, and corrective actions and preventative modifications, if necessary. This proposed AD would also provide for optional terminating action for the repetitive inspections under certain conditions. We are proposing this AD to detect and correct cracking in a bulkhead lower frame web and inner chord, which could result in a severed frame and induced skin cracks, and lead to rapid decompression of the fuselage.
