Federal Aviation Administration June 17, 2013 – Federal Register Recent Federal Regulation Documents

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.

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.

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Federal Register of March 6, 2013, to establish Class E airspace at Cleveland Regional Jetport, Cleveland, TN, is being withdrawn.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.
