Proposed Amendment of Class E Airspace, Belfast, ME
This action proposes to amend Class E airspace extending upward from 700 feet above the surface at Belfast Municipal Airport, Belfast, ME, to accommodate airspace reconfiguration due to the decommissioning of the Belfast non-directional radio beacon and cancellation of the NDB approach. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at this airport. This action also would update the geographic coordinates of this airport.
Airworthiness Directives; The Boeing Company Airplanes
We propose to remove AD 93-14-19, which applies to certain The Boeing Company Model 767-200 and -300 series airplanes. AD 93-14-19 requires inspections for disbonding of the trailing edge wedge of the leading edge slat; and repair, if necessary. Since we issued AD 93-14- 19, an updated stability and control analysis showed that the worst- case scenario of a trailing edge wedge disbond in-flight would not adversely affect the controllability of the airplane. Accordingly, we propose to remove AD 93-14-19.
Airworthiness Directives; Airbus Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A318 series airplanes; Model A319 series airplanes; Model A320 series airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, -232, -251N, -253N, and -271N airplanes. This proposed AD was prompted by a revision of an airworthiness limitation item (ALI) document, which requires more restrictive maintenance requirements and airworthiness limitations. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate new maintenance requirements and airworthiness limitations. We are proposing this AD to address the unsafe condition on these products.
