Pipeline Safety: Information Collection Activities
In accordance with the Paperwork Reduction Act of 1995, PHMSA invites comments on two information collections that we will be submitting to the Office of Management and Budget (OMB) for renewal. The information collections relate to the pipeline integrity management requirements for gas transmission pipeline operators and the response plan requirements for operators of onshore oil pipelines. A Federal Register Notice with a 60-day comment period soliciting comments on the following information collection was published in the Federal Register on May 9, 2012, (77 FR 27279) under Docket No. PHMSA-2012-0094. No comments were received. The purpose of this notice is to allow the public an additional 30 days to submit comments to OMB on the information collection described below.
Airworthiness Directives; Piper Aircraft, Inc. Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Piper Aircraft, Inc. (type certificate previously held by The New Piper Aircraft Inc.) PA-28, PA-32, PA-34, and PA-44 airplanes. This proposed AD was prompted by reports of control cable assembly failures that may lead to failure of the horizontal stabilator control system and could result in loss of pitch control. This proposed AD would require inspections of the stabilator control system and replacement of parts as necessary. We are proposing this AD to correct the unsafe condition on these products.
Airworthiness Directives; Bombardier, Inc. Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-400 series airplanes. This proposed AD was prompted by cases of on-ground failure of the screw cap or end cap of hydraulic accumulators on other airplane models, resulting in high-energy impact damage to adjacent systems and structure. This proposed AD would require inspecting for a part number and replacing the affected parking brake hydraulic accumulator, and relocating the parking brake accumulator, on the subject airplanes. We are proposing this AD to prevent failure of the screw caps and/or end caps of the parking brake hydraulic accumulator, which could result in damage to the airplane's primary structures, with potential adverse effect on the airplane's controllability.
Alaskan Fuel Hauling as a Restricted Category Special Purpose Flight Operation
This notice of policy announces Alaskan fuel hauling as a restricted category special purpose operation under Title 14 of the Code of Federal Regulations (14 CFR) 21.25(b)(7), for aircraft type-certificated under 14 CFR 21.25(a)(1), for operations within the State of Alaska, to provide bulk fuel to isolated individuals or locations in the State of Alaska.
Standard Instrument Approach Procedures, and Takeoff Minimums and Obstacle Departure Procedures; Miscellaneous Amendments
This rule establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

Application of Key Lime Air Corporation for Commuter Authority
The Department of Transportation is directing all interested persons to show cause why it should not issue an order finding Key Lime Air Corporation fit, willing, and able, and awarding it a Commuter Air Carrier Authorization.
Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC- 9-83 (MD-83), DC-9-87 (MD-87), and MD-88 airplanes. This proposed AD was prompted by reports of fatigue cracks found in Stringer 11 at the outboard flap, inboard drive hinge at Station Xrs=164.000. This proposed AD would require repetitive inspections for cracks in Stringer 11, and a splice repair if necessary; and repetitive post-repair inspections, and repair if necessary. We are proposing this AD to detect and correct such cracking, which could result in the wing structure not supporting the limit load condition, which could lead to loss of structural integrity of the wing.

We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model MD-90-30 airplanes. This proposed AD was prompted by reports of fatigue cracks found in Stringer 11 at the outboard flap, inboard drive hinge at Station Xrs=164.000. This proposed AD would require repetitive inspections for cracks in Stringer 11, and a splice repair if necessary; and repetitive post-repair inspections, and repair if necessary. We are proposing this AD to detect and correct such cracking, which could result in the wing structure not supporting the limit load condition, which could lead to loss of the structural integrity of the wing.
Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-200 and -200C series airplanes. This proposed AD was prompted by a report of elevator vibration and bearing swage failures. This proposed AD would require, for certain airplanes, repetitive inspections for any discrepancies (such as a gap or a loose spacer) of the aft attach lugs for the elevator tab control mechanism, and replacement if necessary, and for other airplanes, contacting the FAA for inspection or repair instructions and doing the work specified in those instructions. We are proposing this AD to detect and correct discrepancies in the aft attach lugs for the elevator tab control mechanism, which could result in elevator and tab vibration. Consequent structural failure of the elevator or horizontal stabilizer could result in loss of structural integrity and loss of airplane control.
