Prohibition Against Certain Flights in the Simferopol (UKFV) Flight Information Region (FIR)
This action prohibits certain flight operations in a portion of the Simferopol (UKFV) Flight Information Region (FIR) by all U.S. air carriers; U.S. commercial operators; persons exercising the privileges of a U.S. airman certificate, except when such persons are operating a U.S.-registered aircraft for a foreign air carrier; and operators of U.S.-registered civil aircraft, except when such operators are foreign air carriers. The FAA finds this action to be necessary to prevent a potential hazard to persons and aircraft engaged in such flight operations.
Airworthiness Directives; the Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 777 airplanes. This proposed AD was prompted by reports of dual pitch rate sensor (PRS) failures, resulting in autopilot disconnects. This proposed AD would require an inspection to determine the PRS part number and replacement if necessary. We are proposing this AD to prevent a dual PRS failure that could cause an automatic disengagement of the autopilot and autoland, which may prevent continued safe flight and landing if disengagement occurs at low altitude and the flight crew is unable to safely assume control and execute a go-around or manual landing.
