Airworthiness Directives; Dassault Aviation Airplanes
The FAA withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 7X airplanes. The proposed AD would have required revising the maintenance program to incorporate a limitation that reduced time between overhauls, and required an initial overhaul, of the direct current (DC) generator (bearings). Since the proposed AD was issued, we have received new data that confirm the identified unsafe condition is not sufficient to warrant issuance of an AD. Accordingly, the proposed AD is withdrawn.
Airworthiness Directives; Bombardier, Inc. Airplanes
We propose to adopt a new airworthiness directive (AD) for all Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This proposed AD was prompted by a report that the safe life limit and inspection requirements for the horizontal stabilizer trim actuator (HSTA) attachment pins and trunnions were not listed in the Airworthiness Limitations Section of the maintenance program. This proposed AD would require inspecting the trunnions and upper and lower pins for gouges, scratches, and corrosion, and replacing if necessary; and adding serial numbers and new part numbers to certain trunnions, and upper and lower pins. This proposed AD would also require revising the maintenance program to incorporate the information specified in certain temporary revisions of the limitations section. We are proposing this AD to detect and correct cracking, gouges, scratches, and corrosion of the HSTA attachment pins and trunnions, which could result in failure of these pins and trunnions and consequent disconnection of the horizontal stabilizer and subsequent loss of controllability of the airplane.
Establishment of Restricted Areas R-5402, R-5403A, R-5403B, R-5403C, R-5403D, R-5403E, and R-5403F; Devils Lake, ND
This action establishes restricted area airspace within the Devils Lake Military Operations Area (MOA), overlying Camp Grafton Range, in the vicinity of Devils Lake, ND. The new restricted areas permit realistic training in modern tactics to be conducted at Camp Grafton Range while ensuring the safe and efficient use of the National Airspace System (NAS) in the Devils Lake, ND, area. Unlike restricted areas which are designated under Title 14 Code of Federal Regulations (14 CFR) part 73, MOAs are not regulatory airspace. However, since the restricted areas overlap the Devils Lake East MOA, the FAA is including a description of the Devils Lake East MOA change in this rule. The MOA change described herein will be published in the National Flight Data Digest (NFDD).
