Privacy Act of 1974; System of Records Notice
Pursuant to the Privacy Act of 1974, the Department of Transportation proposes to add a new system of records titled Vehicle and Driver Research, Test, and Evaluation Records. This system maintains records collected in support of, or during the conduct of, research, development, test, and evaluation activities conducted by the Research and Innovative Technology Administration. This new system will be added to the Department's inventory of record systems.
Submission of U.S. Carrier and Airport Tarmac Delay Contingency Plans to Department of Transportation for Approval
The FAA Modernization and Reform Act of 2012 requires covered U.S. carriers and U.S. airports to submit to the Secretary of Transportation for review and approval tarmac delay contingency plans on or before May 14, 2012. The U.S. Department of Transportation's Office of Aviation Enforcement and Proceedings (Enforcement Office) will be establishing an electronic submission system to enable covered airlines and airports to submit the required plans through the World Wide Web. The Enforcement Office plans to issue another notice within 45 days that will provide information on how covered carriers and airports can submit these required plans. Submissions of the plans should not be made prior to that date to ensure proper review and recording.
Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 757 airplanes. This proposed AD was prompted by fuel system reviews conducted by the manufacturer. This proposed AD would require modifying the fuel quantity indication system (FQIS) wiring or fuel tank systems to prevent development of an ignition source inside the center fuel tank. We are proposing this AD to prevent ignition sources inside the center fuel tank, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
Airworthiness Directives; General Electric Company (GE) Turbofan Engines
We are adopting a new airworthiness directive (AD) for all GE CF6-80C2 model turbofan engines, including engines marked on the engine data plate as CF6-80C2B7F1. This AD was prompted by a report of a supplier shipping a batch of nonconforming No. 3 bearing packings that had incorrect cooling holes and by subsequent reports of nonconforming No. 3 bearing packings being installed on engines in service. This AD requires a one-time inspection of the No. 3 bearing packing for an incorrect cooling hole size and, if it is found nonconforming, removing the packing and removing certain engine rotating life-limited parts (LLPs), if they were operated with unacceptable rotor bore cooling flow for a specified number of cycles. We are issuing this AD to prevent an uncontained failure of the high-pressure compressor (HPC) rotor or the low-pressure turbine (LPT) rotor, or both, which could cause damage to the airplane.
Airworthiness Directives; BRP-Powertrain GmbH & Co KG Rotax Reciprocating Engines
We are adopting a new airworthiness directive (AD) for BRP- Powertrain GmbH & Co KG Rotax 912 S2, 912 S3, and 914 F2 reciprocating engines. This AD requires performing a one-time inspection of the oil system for leaks and a torque check of the oil pump attachment bolts, and if leaks are detected, performing a one-time inspection of the oil pump and engine valve train, on certain serial number (S/N) BRP- Powertrain GmbH & Co KG Rotax 912 S2, 912 S3, and 914 F2 reciprocating engines. This AD was prompted by the discovery that during engine production, some engines may not have had the oil pump attachment bolts torqued to specification. We are issuing this AD to prevent oil leaks, which could result in an in-flight engine shutdown and forced landing.
Airworthiness Directives; Pratt & Whitney Division Turbofan Engines
We are adopting a new airworthiness directive (AD) for all Pratt & Whitney PW4050, PW4052, PW4056, PW4060, PW4060A, PW4060C, PW4062, PW4062A, PW4152, PW4156, PW4156A, PW4158, PW4160, PW4460, PW4462, and PW4650 turbofan engines, including models with any dash number suffix. This AD was prompted by an engine overspeed event that occurred during taxi and resulted in a high-pressure compressor surge and tailpipe fire. This AD requires replacing Pratt & Whitney fuel metering units (FMUs), part numbers (P/Ns) 53T335 (HS 801000-1), 55T423 (HS 801000-2), and 50U150 (HS 801000-3) at the next shop visit after the effective date of this AD. We are issuing this AD to prevent engine overspeed on these engines, which could result in an uncontained engine failure and damage to the airplane.
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.
