Department of Transportation May 9, 2017 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Bombardier, Inc., Airplanes
Document Number: 2017-09325
Type: Proposed Rule
Date: 2017-05-09
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede Airworthiness Directive (AD) 2014-25- 01, for certain Bombardier, Inc., Model DHC-8-400 series airplanes. AD 2014-25-01 currently requires modifying the nose landing gear (NLG) trailing arm and installing a new pivot pin retention mechanism. Since we issued AD 2014-25-01, we have received reports of discrepancies of a certain bolt at the pivot pin link, resulting in corrosion of the bolt. This proposed AD would instead require modifying the NLG shock strut assembly. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Bombardier, Inc. (Type Certificate Previously Held by Canadair Limited) Airplanes
Document Number: 2017-09324
Type: Proposed Rule
Date: 2017-05-09
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-215-6B11 (CL-415 Variant) airplanes. This proposed AD was prompted by a report indicating that an oxygen bottle was found loose while the clamp strap was in the locked position. This proposed AD would require modification of the clamp strap and installation of additional shims, as applicable, to the flight crew's oxygen bottle retaining structures. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Dassault Aviation Airplanes
Document Number: 2017-09323
Type: Rule
Date: 2017-05-09
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for all Dassault Aviation Model FAN JET FALCON airplanes; all Model FAN JET FALCON SERIES C, D, E, F, and G airplanes; and all Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes. This AD was prompted by a determination that inspections for discrepancies of the fuselage bulkhead are necessary. This AD requires repetitive inspections for discrepancies of the fuselage bulkhead, and repair if necessary. We are issuing this AD to address the unsafe condition on these products.
Special Conditions: Gulfstream Aerospace LP, Model Gulfstream 200 Airplane; Non-Rechargeable Lithium Battery Installations
Document Number: 2017-09320
Type: Rule
Date: 2017-05-09
Agency: Federal Aviation Administration, Department of Transportation
These special conditions are issued for non-rechargeable lithium battery installations on the Gulfstream Aerospace LP (GALP) Model Gulfstream 200 airplane, as modified by Gulfstream Aerospace Corporation (Gulfstream). Non-rechargeable lithium batteries are a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
Special Conditions: Bombardier Aerospace Inc., Model CL-600-2E25 Airplane; Non-Rechargeable Lithium Battery Installations
Document Number: 2017-09319
Type: Rule
Date: 2017-05-09
Agency: Federal Aviation Administration, Department of Transportation
These special conditions are issued for non-rechargeable lithium battery installations on the Bombardier Aerospace Inc. (Bombardier) Model CL-600-2E25 airplane. Non-rechargeable lithium batteries are a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
MU-2B Series Airplane Training Requirements Update; Correction
Document Number: 2017-09316
Type: Rule
Date: 2017-05-09
Agency: Federal Aviation Administration, Department of Transportation
The FAA is correcting a final rule published on September 7, 2016. In that rule, the FAA amended its regulations to relocate and update the content of SFAR No. 108 to the newly created subpart N of part 91 in order to improve the safety of operating the Mitsubishi Heavy Industries (MHI) MU-2B series airplane. This document corrects two errors in the codified text of the final rule.
Airworthiness Directives; Dassault Aviation Airplanes
Document Number: 2017-08829
Type: Rule
Date: 2017-05-09
Agency: Federal Aviation Administration, Department of Transportation
We are superseding Airworthiness Directive (AD) 2013-03-12 for all Dassault Aviation Model MYSTERE-FALCON 50 airplanes. AD 2013-03-12 required revising the maintenance program to incorporate certain maintenance requirements and airworthiness limitations. This AD requires revising the maintenance or inspection program, as applicable, to incorporate new or revised maintenance requirements and airworthiness limitations. This AD was prompted by issuance of a revision to the airplane maintenance manual (AMM) that introduces new or more restrictive maintenance requirements and/or airworthiness limitations. We are issuing this AD to address the unsafe condition on these products.
