Notice of Request for Extension of Currently Approved Information Collection
The FHWA has forwarded the information collection request described in this notice to the Office of Management and Budget (OMB) to renew an information collection. We published a Federal Register Notice with a 60-day public comment period on this information collection on April 12, 2007. We are required to publish this notice in the Federal Register by the Paperwork Reduction Act of 1995.
Federal Motor Vehicle Safety Standards; Electronic Stability Control Systems; Correction
In April 2007, the agency published a final rule establishing a new Federal motor vehicle safety standard on electronic stability control (ESC) systems for light vehicles. As part of that rulemaking, the final rule notice stated that NHTSA had decided to defer the standard's requirements related to the ESC telltales and controls until the end of the phase-in period (i.e., until September 1, 2011). Accordingly, most of the paragraphs containing ESC telltale and control requirements were prefaced with the phrase ``as of September 1, 2011.'' However, that phrase was inadvertently omitted from two of the paragraphs setting forth ESC telltale and control requirements. These amendments correct this administrative error by adding the phrase ``as of September 1, 2011'' to those paragraphs.
Airworthiness Directives; Eclipse Aviation Corporation Model EA500 Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Eclipse Aviation Corporation (Eclipse) Model EA500 airplanes. This AD requires you to incorporate information into the Limitations section of the airplane flight manual (AFM) that will require operation only in day visual flight rules (VFR), allow only a VFR flight plan, and maintain operation with two pilots. This AD is being issued because of three instances of loss of primary airspeed indication due to freezing condensation within the pitot system. The loss of air pressure in the pitot system could cause the stall warning to become unreliable and the stick pusher, overspeed warning, and autopilot to not function. The concern is heightened by the aerodynamic characteristics of the Eclipse Model EA500 airplane, which relies on the stall warning and the stick pusher to alert the pilot prior to the loss of aircraft control. The standby airspeed is reliable and not affected by this failure mode. A temporary AFM revision prohibits operation in instrument meteorological conditions (IMC), requires two pilots, and limits the airspeed and altitude envelope if the event occurs in flight. The AFM limitations and FAA operational rules allow Model EA500 flight crews to file an instrument flight rule (IFR) flight plan even though the airplane is not approved for flight in IMC. This potentially causes an undue workload burden and confusion when the pilot has to refuse any instructions that take them into IMC. We are issuing this AD to prevent an unsafe condition when Air Traffic Control's (ATC's) ability to maintain traffic separation is compromised because an airplane on an IFR flight plan cannot accept a flight plan into IMC.
