Notice of proposed rulemaking (NPRM).

The Federal Aviation Administration (FAA) proposes to revise its regulations to substitute weather reports from the National Weather Service with weather reports prepared by FAA and other sources approved by the Administrator.

Therefore, this change is necessary to remove outdated references and to maintain weather awareness in the National Airspace System.
