Type: Rule
Date: 2021-02-24
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 727 series airplanes. This AD was prompted by a determination that excessive sealant coating on internal wing Structural Significant Items (SSIs) may not reveal cracks during inspections required by AD 98-11-03 R1. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate inspections that will give no less than the required damage tolerance rating (DTR) for certain SSIs of the wing. This AD also requires repetitive inspections for cracking of the affected SSIs and repair if necessary. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; De Havilland Aircraft of Canada Limited (Type Certificate Previously Held by Bombardier, Inc.) Airplanes
Document Number: 2021-03597
Type: Proposed Rule

Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede Airworthiness Directive (AD) 2015-17-08, which applies to certain Bombardier, Inc. Model DHC-8-400 series airplanes. AD 2015-17-08 requires installing new cable assemblies with a pull-down resistor. Since the FAA issued AD 2015-17- 08, a modification has been developed to address all known single point failures that could lead to runaway of the nose wheel steering (NWS) system. This proposed AD would require modifications to the NWS system. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2021-03595
Type: Proposed Rule
Date: 2021-02-24
Agency: Federal Aviation Administration, Department of Transportation
The FAA is revising an earlier proposal for certain The Boeing Company Model 767-200, -300, -300F, and -400ER series airplanes. This action revises the notice of proposed rulemaking (NPRM) by adding airplanes to the applicability and proposing to require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is proposing this airworthiness directive (AD) to address the unsafe condition on these products. Since these actions would impose an additional burden over that in the NPRM, the FAA is reopening the comment period to allow the public the chance to comment on these changes.

Agency: Federal Aviation Administration, Department of Transportation
The FAA is revising an earlier proposal to supersede Airworthiness Directives (AD) 2000-23-04 R1 and AD 2018-20-14, which apply to certain ATR-GIE Avions de Transport R[eacute]gional Model ATR42-500 airplanes. This action revises the notice of proposed rulemaking (NPRM) by including new or more restrictive airworthiness limitations. The FAA is proposing this AD to address the unsafe condition on these products. Since this action would impose an additional burden over those in the NPRM, the FAA is reopening the comment period to allow the public the chance to comment on these changes.
Airworthiness Directives; MHI RJ Aviation ULC (Type Certificate Previously Held by Bombardier, Inc.) Airplanes
Document Number: 2021-03589
Type: Proposed Rule
Date: 2021-02-24
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede Airworthiness Directive (AD) 2019-22-07, which applies to all MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, 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 2019-22-07 requires revising the existing airplane flight manual (AFM) to include a limitation and an abnormal operating procedure for the Automatic Flight Control System (AFCS). Since the FAA issued AD 2019-22-07, it was found that the limitation and abnormal operating procedure did not include reference to a certain mode. This proposed AD would require revising the existing AFM and adding airplanes to the applicability. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Bombardier, Inc., Airplanes
Document Number: 2021-03588
Type: Proposed Rule
Date: 2021-02-24
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for all Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This proposed AD was prompted by reports indicating that the left- and right-hand elevator torque tube bearings were contaminated with sand and corrosion, restricting free rotation. This proposed AD would require repetitive general visual inspections of the left- and right- hand elevator torque tube bearings for any sand, dust, or corrosion; repetitive functional tests of the elevator control system; and replacement of the elevator torque tube bearings if necessary. The FAA is proposing this AD to address the unsafe condition on these products.
