Federal Aviation Administration July 21, 2021 – Federal Register Recent Federal Regulation Documents

The FAA is adopting a new airworthiness directive (AD) for certain International Aero Engines AG (IAE) V2500 model turbofan engines. This AD was prompted by a review of investigative findings from an event involving an uncontained failure of a high-pressure turbine (HPT) 1st-stage disk that resulted in high-energy debris penetrating the engine cowling. This AD requires performance of an ultrasonic inspection (USI) of the HPT 1st-stage disk and HPT 2nd-stage disk and, depending on the results of the inspections, replacement of the HPT 1st-stage disk or HPT 2nd-stage disk with a part eligible for installation. The FAA is issuing this AD to address the unsafe condition on these products.

This action proposes to amend Class E airspace extending upward from 700 feet above the surface in Bangor, ME, by establishing airspace for Eastern Maine Medical Center Heliport, Bangor, ME, to accommodate new area navigation (RNAV) global positioning system (GPS) standard instrument approach procedures (SIAPs) serving this heliport. Also, while reviewing the Class E airspace extending upward from 700 feet above the surface at Bangor International Airport, the FAA determined an airspace modification, omitting the Bangor VORTAC, is required. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations in the area.
