Full official abstract

The FAA adopts a new airworthiness directive (AD) for certain Raytheon Aircraft Company (Raytheon) Model B100 airplanes. This AD requires you to drill holes in the hot lip tube "B" nuts, tighten the "B" nuts to specified torque ranges, and secure the "B" nuts with safety wire. This AD is the result of reports of loose "B" nuts on the engine inlet that may loosen and permit a leak in the engine inlet anti-ice system. We are issuing this AD to detect and correct loose "B" nuts on the engine inlet, which could result in failure of the engine inlet anti-ice system and consequent ice buildup. This failure and ice buildup could lead to an engine's ingestion of ice with loss of engine power or loss of engine.
