Special Conditions: Cirrus Design Corporation Model SF50 Airplane; Function and Reliability Testing; Withdrawal
The FAA is withdrawing a previously published notice granting special conditions for the Cirrus Design Corporation model SF50 airplane. We are withdrawing Special Condition No. 23-248-SC through mutual agreement with Cirrus Design Corporation.
Special Conditions: The Boeing Company, Model 717-200 Series Airplanes; Seats With Inflatable Lapbelts
These special conditions are issued for the Boeing Model 717- 200 series airplanes. These airplanes will have a novel or unusual design feature associated with seats with inflatable lapbelts. 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.
Petition for Exemption; Summary of Petition Received
This notice contains a summary of a petition seeking relief from specified requirements of Title 14, Code of Federal Regulations (14 CFR). The purpose of this notice is to improve the public's awareness of, and participation in, this aspect of the FAA's regulatory activities. Neither publication of this notice nor the inclusion or omission of information in the summary is intended to affect the legal status of the petition or its final disposition.
Airworthiness Directives; Eurocopter France (Eurocopter) Model Helicopters
We propose to supersede an existing airworthiness directive (AD) for Eurocopter Model AS350B, BA, B1, B2, C, D, and D1 helicopters and Model AS355E, F, F1, F2, and N helicopters with certain part- numbered tail gearbox (TGB) control levers installed. The existing AD currently requires repetitive visual inspections of the TGB control lever for a crack and replacing a cracked TGB control lever with an airworthy TGB control lever. Since we issued that AD, we have received reports of cracking on the opposite area of the TGB control lever. This proposed AD would retain the current requirements and would also require inspecting other areas of the TGB control lever not previously inspected and at additional inspection intervals. The proposed actions are intended to prevent failure of the TGB control lever, loss of tail rotor control, and subsequent loss of control of the helicopter.
Airworthiness Directives; Hawker Beechcraft Corporation (Type Certificate Previously Held by Raytheon Aircraft Company) Airplanes
We are adopting a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation (Type Certificate Previously Held by Raytheon Aircraft Company) Model BAe.125 Series 800A (including C-29A and U-125), and 800B airplanes; and Model Hawker 800 (including variant U-125A) and 800XP airplanes modified in accordance with a certain winglet supplemental type certificate. This AD requires revising the Limitations section of the airplane flight manual (AFM) and installing placards on the instrument panel. This AD was prompted by reports of several instances of severe vibration and wing/aileron oscillations. We are issuing this AD to prevent vibration and wing/aileron oscillations, which could cause structural damage or lead to divergent flutter, and result in loss of integrity of the wing, loss of control of the airplane, and in-flight breakup.
Proposed Establishment of Class E Airspace; Cleveland, TN
A notice of proposed rulemaking published in the Federal Register of March 6, 2013, to establish Class E airspace at Cleveland Regional Jetport, Cleveland, TN, is being withdrawn. Upon review, the FAA found that, for clarity, combining this proposed rulemaking with another proposal to amend existing airspace is necessary.
