Dornier 228

Airworthiness Directives; RUAG Aerospace Services GmbH (Type Certificate Previously Held by Dornier Luftfahrt GmbH) Airplanes

The FAA is superseding Airworthiness Directive (AD) 2007-02- 13, which applied to certain Dornier Luftfahrt GmbH (type certificate currently held by RUAG Aerospace Services GmbH) Model Dornier 228-212 airplanes. AD 2007-02-13 required inspecting the landing gear carbon brake assembly. This AD requires inspecting certain carbon brake assemblies and corrective actions if necessary. This AD was prompted by mandatory continuing airworthiness information (MCAI) issued by the European Union Aviation Safety Agency (EASA) to correct an unsafe condition on an aviation product. The MCAI identifies the unsafe condition as loose bolts and nuts on the landing gear carbon brake assembly. The FAA is issuing this AD to address the unsafe condition on these products.

Airworthiness Directives; Dornier Luftfahrt GmbH 228 Series Airplanes

This document adopts a new airworthiness directive (AD) that applies to all Dornier Luftfahrt GmbH (Dornier) 228 series airplanes that are equipped with pneumatic deicing boots. This AD requires revising the Airplane Flight Manual (AFM) to include requirements for activation of the airframe pneumatic deicing boots. This AD is the result of reports of in-flight incidents and an accident that occurred in icing conditions where the airframe pneumatic deicing boots were not activated. The actions specified by this AD are intended to assure that flightcrews activate the pneumatic wing and tail deicing boots at the first signs of ice accumulation. This action will prevent reduced controllability of the aircraft due to adverse aerodynamic effects of ice adhering to the airplane prior to the first deicing cycle.

Airworthiness Directives; Dornier Luftfahrt GmbH Models 228-100, 228-101, 228-200, 228-201, 228-202, and 228-212 Airplanes

This amendment adopts a new airworthiness directive (AD) that applies to certain Dornier Luftfahrt GmbH (Dornier) Models 228-100, 228-101, 228-200, 228-201, 228-202, and 228-212 airplanes. This AD requires modifying the logic in the failure detection circuits of the landing gear uplock switches. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. The actions specified by this AD are intended to prevent a false warning indication of landing gear failure because of the design of the landing gear warning system, which could result in incorrect actions from the pilot based on the warning indications.

Airworthiness Directives; Dornier Luftfahrt GmbH Models 228-100, 228-101, 228-200, and 228-201 Airplanes

This action confirms the effective date of Airworthiness Directive (AD) 98-06-13 which applies to Models 228-100, 228-101, 228- 200, and 228-201 airplanes equipped with certain main landing gear (MLG). AD 98-06-13 requires replacing the MLG axle assembly with an MLG axle assembly of improved design. This AD was the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. The actions specified in this AD are intended to prevent main landing gear failure, which, if not corrected, could result in loss of control of the airplane during landing operations.

Airworthiness Directives; Dornier Luftfahrt GmbH Models 228-100, 228-101, 228-200, and 228-201 Airplanes

This amendment adopts a new airworthiness directive (AD) that applies to all Dornier Luftfahrt GmbH (Dornier) Models 228-100, 228- 101, 228-200, and 228-201 airplanes equipped with certain main landing gear (MLG). This action requires replacing the MLG axle assembly with an MLG axle assembly of improved design. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. The actions specified in this AD are intended to prevent main landing gear failure, which, if not corrected, could result in loss of control of the airplane during landing operations.

Airworthiness Directives; Dornier Luftfahrt GMBH Models 228-100, 228-101, 228-200, 228-201, 228-202, and 228-212 Airplanes

This amendment adopts a new airworthiness directive (AD) that applies to all Dornier Luftfahrt GMBH (Dornier) Models 228-100, 228- 101, 228-200, 228-201, 228-202, and 228-212 airplanes. This AD requires amending the Limitations Section of the Dornier 228 Pilot's Operating Handbook (POH) to prohibit the positioning of the power levers below the flight idle stop while the airplane is in flight. This POH amendment will include a statement of consequences if the limitation is not followed. This AD results from numerous incidents and five documented accidents involving airplanes equipped with turboprop engines where the propeller beta was improperly utilized during flight. The actions specified by this AD are intended to prevent loss of airplane control or engine overspeed with consequent loss of engine power caused by the power levers being positioned below the flight idle stop while the airplane is in flight.

Airworthiness Directives; Dornier 228 Series Airplanes

This amendment adopts a new airworthiness directive (AD) that applies to all Dornier 228 series airplanes. This action requires revising the Airplane Flight Manual (AFM) to provide the flight crew with recognition cues for, and procedures for exiting from, severe icing conditions, and to limit or prohibit the use of various flight control devices. This amendment is prompted by results of a review of the requirements for certification of the airplane in icing conditions, new information on the icing environment, and icing data provided currently to the flight crews. The actions specified by this AD are intended to minimize the potential hazards associated with operating the airplane in freezing rain or freezing drizzle conditions by providing more clearly defined procedures and limitations associated with such conditions.
