Bombardier Inc. Model Otter DHC-3 Airplanes
The FAA is revising Airworthiness Directive (AD) 2004-05-01, which applies to certain Bombardier Inc. (formerly deHavilland Inc.) Model Otter DHC-3 airplanes that have turbine engines installed per one of three supplemental type certificates (STC). AD 2004-05-01 currently prohibits you from operating any affected airplane with these engine and propeller configurations unless a new STC for an elevator servo-tab with a redundant control linkage is installed. The FAA has since evaluated concerns, comments, and technical information related to all three STC configurations. Based on that evaluation, we have determined that further evaluation is necessary for the STCs owned by Texas Turbines Conversions, Inc., and Canada Turbine Conversions, Inc. Therefore, we are removing reference to these STCs from the AD, and the AD will only apply to those Bombardier Inc. airplanes that incorporate STC No. SA3777NM (A.M.

This AD requires replacing certain serial-numbered (SN) cylinders supplied by ECi before further flight. This AD results from reports of 34 failures of cylinder heads marketed by ECi. We are issuing this AD to prevent loss of engine power due to cracks in the cylinder head and possible engine failure caused by separation of a cylinder head.

Hartzell Propeller Inc. Models HC-B5MP-3C/M10876K Propellers
The FAA is superseding an existing airworthiness directive (AD) for Hartzell Propeller Inc. Model HC-B5MP-3C/M10876K propellers, installed on Short Brothers Model SD3-60 airplanes. That AD currently requires initial and repetitive removal, disassembly, inspection, and rework if necessary of Hartzell Propeller Inc. Model HC-B5MP-3C/M10876K propellers until blades are replaced with new design blades, no later than March 31, 1988. This ad requires installation of new design blades before further flight, on Hartzell Propeller Inc. Models HC-B5MP-3C/ M10876K propellers. This AD supersedure is prompted by a review of all currently effective ADs, which found that AD 87-16-02 was not published in the Federal Register to make it effective to all operators, as opposed to just the operators who received actual notice of the original AD. We are issuing this AD to prevent propeller blade separation near the hub, which could result in engine separation from the airplane.

Goodrich Avionics Systems, Inc. TAWS8000 Terrain Awareness Warning System
The FAA supersedes Airworthiness Directive (AD) 2003-13-08, which currently applies to all Goodrich Avionics Systems, Inc. (Goodrich) TAWS8000 terrain awareness warning systems (TAWS) that are installed on airplanes. AD 2003-13-08 currently requires you to inspect the TAWS installation and remove any TAWS where both the TAWS and any other device are connected to the same baro set potentiometer. AD 2003- 13-08 also prohibits future installation of any TAWS8000 TAWS that incorporates hardware "Mod None", "Mod A", or "Mod B". This AD is the result of omitting from AD 2003-13-08 a provision that prohibits reconfiguring an installed TAWS8000 TAWS after it passes the inspection unless it incorporates hardware "Mod C". This AD retains the actions of AD 2003-13-08 and prohibits future installation or reconfiguration of any TAWS8000 TAWS that does not incorporate hardware "Mod C". We are issuing this AD to prevent the loading of the baro set potentiometer, which could result in an unacceptable altitude error. That condition could cause the pilot to make flight decisions that put the airplane in unsafe flight conditions.

NARCO Avionics Inc. AT150 Transponders
The FAA is adopting a new airworthiness directive (AD) for certain serial numbers (SNs) of NARCO Avionics Inc. AT150 transponders. This AD requires modification to the transponder by adding a resistor and transistor to the circuit board. This AD results from reports of AT150 transponders not recognizing and responding properly to Mode S interrogations from Mode S ground stations and Traffic Alert and Collision Avoidance System (TCAS-II) airborne equipment. We are issuing this AD to prevent loss of aircraft airspace separation and the possibility of mid-air collision.

BURKHARDT GROB LUFT-UND RAUMFAHRT GmbH & CO KG Models G103 Twin ASTIR, G103 TWIN II, G103 TWIN III ACRO, and G103 C Twin III SL Sailplanes
The FAA adopts a new airworthiness directive (AD) for certain BURKHARDT GROB LUFT-UND RAUMFAHRT GmbH & CO KG (Grob) Models G103 Twin ASTIR, G103 TWIN II, G103 TWIN III ACRO, and G103 C Twin III SL sailplanes. This AD requires you to replace the center of gravity (CG) release hook attachment brackets with brackets of improved design. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this AD to prevent abnormal or uncontrolled sailplane release due to cracked CG release hook attachment brackets. This condition could result in reduced or loss of sailplane control.

Glasflugel Models Mosquito and Club Libelle 205 Sailplanes
The FAA adopts a new airworthiness directive (AD) for all Glasflugel Models Mosquito and Club Libelle 205 sailplanes. This AD requires you to replace the rudder actuator arm with an improved design rudder actuator arm. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this AD to prevent the rudder attachment actuator arm from failing due to ground handling damage. This failure could eventually result in reduced or loss of sailplane control.

Schempp-Hirth Flugzeugbau GmbH Models Ventus-2a, Ventus-2b, Discus-2a, and Discus-2b Sailplanes
The FAA adopts a new airworthiness directive (AD) for all Schempp-Hirth Flugzeugbau GmbH (Schempp-Hirth) Models Ventus-2a, Ventus-2b, Discus-2a, and Discus-2b sailplanes. This AD requires you to inspect and modify the elevator mass balance. For Models Discus-2a and Discus-2b sailplanes only, this AD also requires you to replace the elevator pushrod. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this AD to detect and correct problems within the sailplane elevator control system before they lead to flutter and sailplane instability. This could eventually result in loss of sailplane control.

HPH s. r. o. Models Glasflügel 304CZ, 304CZ-17, and 304C Sailplanes
The FAA adopts a new airworthiness directive (AD) for certain HPH s. r. o. (HPH) Models Glasfl[uuml]gel 304CZ, 304CZ-17, and 304C sailplanes. This AD requires you to inspect to determine the airbrake handle attachment rivet material. This AD also requires you to replace any non-steel rivet with a steel rivet. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for the Czech Republic. We are issuing this AD to prevent the airbrake handle from becoming loose, which could result in failure of the airbrake control. This failure could lead to loss of control of the sailplane.
