Federal Aviation Administration December 17, 2015 – Federal Register Recent Federal Regulation Documents

The FAA hereby provides notice of intent to release approximately 20.05 acres at the Orlando Executive Airport, Orlando, FL from the conditions, reservations, and restrictions as contained in a Quitclaim Deed agreement between the FAA and the City of Orlando, dated August 9, 1961. The release of property will allow the City of Orlando to dispose of the property for other than aeronautical purposes. The property is located within the Southeast quandrant of the airport. The parcel is currently designated as non-aeronautical use. The property will be released of its federal obligations for municipal purposes. The fair market value of this parcel has been determined to be $3,880,000. Documents reflecting the Sponsor's request are available, by appointment only, for inspection at the Greater Orlando Aviation Authority at Orlando International Airport and the FAA Airports District Office.

The Federal Aviation Administration (FAA) is correcting a final rule published on October 1, 2015. In that rule, the FAA amended its certification procedures and marking requirements for aeronautical products and articles. This action corrects the effective date of the final rule to permit an earlier implementation of the rule's provisions that allow production approval holders to issue authorized release documents for aircraft engines, propellers, and articles. It also permits an earlier implementation date for production certificate holders to manufacture and install interface components, and provides earlier relief from the current requirement that fixed-pitch wooden propellers be marked using an approved fireproof method.

We propose to supersede Airworthiness Directive (AD) 2012-24- 06 for certain Saab AB, Saab Aeronautics (formerly known as Saab AB, Saab Aerosystems) Model 340A (SAAB/SF340A) and SAAB 340B airplanes. AD 2012-24-06 requires replacing the stall warning computer (SWC) with a new SWC, which provides an artificial stall warning in icing conditions, and modifying the airplane for the replacement of the SWC. Since we issued AD 2012-24-06, a determination was made that airplanes with certain modifications were excluded from the AD applicability and are affected by the identified unsafe condition and the SWC required by AD 2012-24-06 contained erroneous logic. This proposed AD would add airplanes to the applicability, and would add requirements to replace the existing SWCs with new, improved SWCs and modify the airplane for the new replacement of the SWC. We are proposing this AD to prevent natural stall events during operation in icing conditions, which could result in loss of control of the airplane.
