Federal Aviation Administration June 28, 2011 – Federal Register Recent Federal Regulation Documents

The Federal Aviation Administration proposes to rule and invite public comment on the release of land at the Lehigh Valley International Airport, Allentown, Pennsylvania under the provisions of Section 47125(a) of Title 49 United States Code (U.S.C.). The parcel is a generally north/south rectangular property whose south end of the parcel is located at the north end of Lynnwood Dr. The property is currently vacant land, under agricultural production, and is maintained to protect airspace surfaces of 14 CFR 77.19. The requested release is for the purpose of permitting the Airport Owner to convey title of 14.496 Acres as open space dedication to meet the conditions of an existing zone change (Resolution 07-08), and the Subdivision and Land Development Ordinance of Hanover Township in Northampton County, Pennsylvania. This release will enable the airport to implement the Noise Land Reuse Plan approved by the FAA on May 10, 2010. Documents reflecting the Sponsor's request are available, by appointment only, for inspection at the Airport Manager's office and the FAA Harrisburg Airport District Office.

We propose to supersede an existing airworthiness directive (AD) that applies to certain TCM and R-RM series reciprocating engines. The existing AD currently requires replacement of certain magnetos if they fall within the specified serial number (S/N) range, inspection of the removed magneto to verify that the stop pin is still in place, and, if the stop pin is not in place, inspection of the engine gear train, crankcase, and accessory case. Since we issued that AD, we became aware of an error in the previous AD applicability in the range of magneto S/ Ns affected, and of the need to include certain engines made by R-RM, under license of TCM. This proposed AD would correct the range of S/Ns affected, require the same replacement and inspections, and would add R-RM C-125, C-145, O-300, IO-360, TSIO-360, and LTSIO-520-AE series reciprocating engines to the applicability. We are proposing this AD to correct the unsafe condition on these products.
