Federal Aviation Administration May 24, 2013 – Federal Register Recent Federal Regulation Documents

This action proposes to amend Class D airspace at Rickenbacker International Airport, Columbus, OH. Changes to the airspace description are necessary due to the closure of South Columbus Airport. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) operations for standard instrument approach procedures at the airport. The airport name and geographic coordinates would also be updated.

In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval for to renew an information collection. Feedback from surveys to be conducted under this generic information collection will be used in the prevention of runway collisions and in the medication of the severity and frequency of runway incursions.

The FAA is issuing this notice to advise the public of the thirteenth meeting of the RTCA Special Committee 222, Inmarsat AMS(R)S

This action modifies Class E airspace at Portland-Hillsboro Airport, Portland-Hillsboro, OR, to accommodate aircraft departing and arriving under Instrument Flight Rule (IFR) operations at the airport. Also, the geographic coordinates are updated for the airport. This action, initiated by the biennial review of the Portland-Hillsboro airspace area, improves the safety and management of IFR operations at the airport.

We are adopting a new airworthiness directive (AD) for Eurocopter Deutschland GmbH (ECD) Model MBB-BK 117 C-2 helicopters. This AD requires revising the operating limitations to prohibit flights under instrument flight rules (IFR) or under night visual flight rules (VFR) when the autotrim is inoperative. The actions of this AD are intended to prevent a workload situation whereby stabilizing the helicopter in flight would be difficult if not impossible, resulting in possible loss of helicopter control.

We are superseding an existing airworthiness directive (AD) for all The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. That AD currently requires repetitive inspections to detect cracking of the lower corners of the door frame and cross beam of the forward cargo door, and corrective actions if necessary. That AD also requires eventual modification of the outboard radius of the lower corners of the door frame and reinforcement of the cross beam of the forward cargo door, which terminates the existing repetitive inspections. This new AD revises the compliance times for the preventive modification; adds certain inspections for cracks in the number 5 cross beam of the forward cargo door; and adds inspections of the number 4 cross beam if cracks are found in the number 5 cross beam, and corrective actions if necessary. For certain airplanes, this new AD also adds a one-time inspection for airplanes previously modified or repaired, and a one-time inspection of the reinforcement angle for excessive shimming or fastener pull-up, and corrective actions if necessary. This AD was prompted by additional reports of fatigue cracking in the radius of the lower frames and in the lower number 5 cross beam of the forward cargo door. We are issuing this AD to prevent fatigue cracking of the lower corners of the door frame and number 5 cross beam of the forward cargo door, which could result in rapid depressurization of the airplane.
