Notice of Decision; Gallatin County, MT, Request for Waiver
This document notifies the public that the Federal Aviation Administration has granted a waiver to Gallatin County, MT pursuant to 49 U.S.C. 40125(d). The waiver enables Gallatin County to contract for a public aircraft operation to conduct search and rescue operations without complying with the 90-day lease minimum required under 49 U.S.C. 40102(a)(41)(D).
Special Conditions: Bombardier Aerospace, Models BD-500-1A10 and BD-500-1A11 Series Airplanes; Automatic Speed Protection for Design Dive Speed
This action proposes special conditions for the Bombardier Aerospace Models BD-500-1A10 and BD-500-1A11 series airplanes. These airplanes will have a novel or unusual design feature associated with a reduced margin between design cruising speed, VC/ MC, and design diving speed, VD/MD, based on the incorporation of a high speed protection system that limits nose down pilot authority at speeds above VD/ MD. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed 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.
Airworthiness Directives; the Boeing Company Airplanes
We are revising an earlier proposed airworthiness directive (AD) for certain The Boeing Company Model 767-200, -300, -300F, and - 400ER airplanes. The NPRM proposed to require an inspection of the wing fuel tank access doors to determine whether impact-resistant access doors are installed in the correct locations, and to replace incorrectly installed doors with impact-resistant access doors. The NPRM also proposed to require an inspection for stencils and index markers on impact-resistant access doors, and application of new stencils or index markers if necessary. In addition, the NPRM proposed to require revising the maintenance program to incorporate changes to the airworthiness limitations section. The NPRM was prompted by reports indicating that a standard access door was located where an impact- resistant access door was required, and stencils were missing from some impact-resistant access doors. This action revises the NPRM by adding airplanes to the applicability. We are proposing this supplemental NPRM (SNPRM) to prevent foreign object penetration of the fuel tank from uncontained engine failure or tire debris, which could cause a fuel leak near an ignition source (e.g., hot brakes or engine exhaust nozzle), consequently leading to a fuel-fed fire. 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.
Special Conditions: Boeing Commercial Airplanes, Model 767-2C Airplane; Interaction of Fuel Systems and Structures
This action proposes special conditions for the Boeing Model 767-2C airplane. This airplane will have novel or unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. These design features include the addition of four body fuel tanks and a modified fuel management system that, directly or as a result of failure or malfunction, could affect the airplane's structural performance. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for these design features. These proposed 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.
Airworthiness Directives; Alexandria Aircraft LLC Airplanes
We propose to supersede Airworthiness Directive (AD) 75-20-06, which applies to certain Alexandria Aircraft LLC (type certificate previously held by Bellanca Aircraft Corp., Viking Aviation, Inc., and Bellanca, Inc.) Models 14-19-3A, 17-30, 17-30A, 17-31, 17-31A, 17- 31ATC, and 17-31TC airplanes. AD 75-20-06 requires repetitively inspecting the aft fuselage structure near the top of the vertical side tubing, which connects the horizontal stabilizer carry-through to the upper fuselage longeron, for cracks and installing the manufacturer's service repair kit as a terminating action for the repetitive inspections to repair any cracks found. Since we issued AD 75-20-06, we have determined that installing the service kit has not prevented cracks from occurring. We have also determined that all affected airplane serial numbers should be included in the Applicability section. This proposed AD would require continued repetitive inspections of the aft fuselage structure near the top of the vertical side tubing for cracks and making all necessary replacements of cracks parts. This proposed AD would also add additional serial number airplanes to the Applicability section. We are proposing this AD to correct the unsafe condition on these products.
Airworthiness Directives; the Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 airplanes. This proposed AD was prompted by reports of deficiencies in the flight control module (FCM) software. This proposed AD would require installing certain FCM software. We are proposing this AD to correct deficiencies in the FCM software, which, if not corrected, could prevent continued safe flight and landing.
Airworthiness Directives; The Boeing Company Airplanes
We propose to supersede Airworthiness Directive (AD) 2013-24- 13, which applies to certain The Boeing Company Model 737-100, -200, - 200C, -300, -400, -500, -600, -700, -700C, -800, and -900 series airplanes. AD 2013-24-13 currently requires replacing the pivot link assembly for certain airplanes, replacing the seat track link assemblies or modifying the existing seat track link assembly for certain airplanes, or modifying the existing seat track link assembly fastener for certain airplanes. AD 2013-24-13 also requires inspecting, changing, or repairing the seat track link assembly for certain other airplanes. Since we issued AD 2013-24-13, a paragraph reference was found to be mis-identified. This proposed AD would correct this paragraph reference. We are proposing this AD to prevent seat detachment in an emergency landing, which could cause injury to occupants of the passenger compartment and affect emergency egress.
