Airworthiness Directives; Fokker Services B.V. Airplanes
We propose to supersede Airworthiness Directive (AD) 2008-05- 18 R1 for certain Fokker Services B.V. Model F.27 Mark 050, 200, 300, 400, 500, 600, and 700 airplanes. AD 2008-05-18 R1 currently requires revising the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness to incorporate new limitations for fuel tank systems. Since we issued AD 2008-05-18 R1, revised service information has been issued to update the Fuel Airworthiness Limitations Items (ALIs) and critical design configuration control limitations (CDCCLs) that address fuel tank system ignition sources. This proposed AD would require a new maintenance or inspection program revision to incorporate the revised ALIs and CDCCLs. This proposed AD would add certain airplanes to the applicability. We are proposing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 767-200, -300, and -400ER series airplanes. This proposed AD was prompted by multiple reports of un- commanded escape slide inflation. This proposed AD would require modifying the regulator valves of the forward entry door, forward service door, aft entry door, and aft service door, and as applicable, modifying the regulator valves of the mid entry door and mid service door. We are proposing this AD to prevent out-of-tolerance trigger mechanism components (sector and sear) in the regulator valves, which can produce insufficient trigger engagement and reduced pull force values, possibly leading to un-commanded deployment of the slide during normal airplane maintenance or operation, and could result in injury to passengers and crew, damage to equipment, and the slide becoming unusable in an emergency evacuation.
Airworthiness Directives; Dassault Aviation
We propose to adopt a new airworthiness directive (AD) for all Dassault Aviation Model FALCON 7X airplanes. This proposed AD was prompted by reports of multiple cases of ram air turbine (RAT) blade damage. This proposed AD would require deployment of the RAT, replacement of the RAT placard with a new RAT placard, and re-identification of the RAT. We are proposing this AD to prevent blade damage to the RAT which could prevent RAT deployment in flight during an emergency, possibly resulting in reduced control of the airplane.
Airworthiness Directives; Bombardier, Inc. Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2B16 (CL-604 Variant) airplanes. This proposed AD was prompted by a determination that certain maintenance tasks for the horizontal stabilizer trim actuator (HSTA) are inadequate. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate new airworthiness limitations for the HSTA. We are proposing this AD to detect and correct premature wear and cracking of the HSTA, which could result in failure of the HSTA and consequent loss of control of the airplane.
Confidential Business Information
This notice proposes to modify the existing procedures for the submission and processing of requests for confidential treatment. NHTSA is proposing that it will defer acting on requests for confidential treatment until it receives a FOIA request for the information, if the Agency decides that making a determination of confidentiality is necessary or if making a determination is in the public interest. In general, unless and until a determination is made, the information for which confidential treatment is requested will not be disclosed. To ensure that requests for confidential treatment will provide an adequate basis for deferred determinations, this notice also proposes that submitters affirmatively specify whether the materials for which confidential treatment is sought were voluntarily submitted and provide an adequate basis for their claim of voluntariness. The proposal also contains provisions addressing agency disposition of inadequate or incomplete requests to ensure that submitters comply with the requirements when making requests for confidential treatment. Additionally, to facilitate communication with those making requests for confidential treatment, this notice proposes that an electronic mail address be provided with all requests. NHTSA is also proposing to amend the regulation to provide submitters of confidential information with the option of submitting their requests for confidential treatment and the materials accompanying these requests electronically.
