Airworthiness Directives; the Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain the Boeing Company Model DC-9-10, DC-9-30, and DC-9-40 series airplanes. This proposed AD was prompted by an evaluation by the design approval holder (DAH) indicating that the aft pressure bulkhead web area is subject to widespread fatigue damage (WFD). This proposed AD would require modifying the aft pressure bulkhead. The modification includes inspecting for cracks around the rivet holes, and repair of any cracking. We are proposing this AD to prevent fatigue cracking of the aft pressure bulkhead, which could result in reduced structural integrity of the airplane.
Airworthiness Directives; Bombardier, Inc. Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model BD-700-1A10 airplanes. This proposed AD was prompted by a report that the manufacturer has determined that some completion centers used the heater/brake monitoring unit (HBMU) logic circuit to control the line voltage of the drain mast heaters. Since the drain mast heaters are connected in parallel with the number 2 pitot static (PS) probe heater circuit, a number 2 PS probe heater failure may not be detected by the fault monitoring capabilities of the HBMU. This proposed AD would require a modification of the air data probes and sensors. We are proposing this AD to detect and correct an unannunciated failure of two PS probe heaters, which could affect controllability of the airplane in icing conditions.

Twenty Fourth Meeting: RTCA Special Committee 213, Enhanced Flight Vision Systems/Synthetic Vision Systems (EFVS/SVS)
The FAA is issuing this notice to advise the public of the twenty fourth meeting of the RTCA Special Committee 213, Enhanced Flight Vision Systems/Synthetic Vision Systems (EFVS/SVS).
Special Conditions: Cirrus Design Corporation, Model SF50; Inflatable Three-Point Restraint Safety Belt With an Integrated Airbag Device
These special conditions are issued for the Cirrus Design Corporation (Cirrus), model SF50. This airplane will have novel and unusual design features associated with installation of an inflatable three-point restraint safety belt with an integrated airbag device at the pilot and co-pilot seats to include optional installations at other passenger seat locations. 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.
Pipeline Safety: Information Collection Activities
In compliance with the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.), this notice announces that the Information Collection Request abstracted below is being forwarded to the Office of Management and Budget (OMB) for review and comments. A Federal Register notice with a 60-day comment period soliciting comments on the following information collection was published on April 23, 2013, (78 FR 23972). PHMSA received one comment in response to that notice. PHMSA is publishing this notice to respond to the comment, provide the public with an additional 30 days to comment on the proposed revisions to the forms and the instructions, and announce that the revised information collection will be submitted to OMB for approval.
Information Collection Available for Public Comments and Recommendations
In accordance with the Paperwork Reduction Act of 1995, this notice announces the Maritime Administration's (MARAD's) intention to request extension of approval for three years of a currently approved information collection.
