Raytheon Aircraft Corporation Beech Models 45 (YT-34), A45 (T-34A, B-45), and D45 (T-34B) Airplanes
The FAA is revising Airworthiness Directive (AD) 2001-13-18, which applies to Raytheon Aircraft Corporation (Raytheon) Beech Models 45 (YT-34), A45 (T-34A, B-45), and D45 (T-34B) airplanes. AD 2001-13-18 currently requires you to repetitively inspect the wing spar assembly for cracks and replace any wing spar assembly found cracked (unless the spar assembly has a crack indication in the filler strip where the direction of the crack is toward the outside edge of the filler strip). AD 2001-13-18 also requires you to report the results of the initial inspection and maintain the flight and operating restrictions required by AD 99-12-02 until the initial inspection is done. We approved alternative methods of compliance (AMOCs) to AD 2001-13-18. We have since determined that those AMOCs do not address all critical areas in the wing spar assemblies and should no longer be valid. We are issuing this revision to AD 2001-13-18 for the purpose of eliminating the AMOCs to AD 2001-13-18. The actions of this AD are intended to prevent wing spar failure caused by fatigue cracks in the wing spar assemblies and ensure the operational safety of the above-referenced airplanes.

Bombardier Inc. Model Otter DHC-3 Airplanes
The FAA adopts a new airworthiness directive (AD) for certain Bombardier Inc. (formerly deHavilland Inc.) Model Otter DHC-3 airplanes that have turbine engines installed per one of three supplemental type certificates (STC). This AD 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. This AD is the result of reports of the control rod to the elevator servo-tab system detaching from the elevator servo-tab, which caused the elevator servo-tab to flutter on airplanes with a turbine engine installed. We are issuing this AD to prevent a single failure of the elevator servo-tab system, which could cause severe tab flutter. This failure could lead to possible loss of control of the airplane.

Mitsubishi Heavy Industries, Ltd., MU-2B Series Airplanes
The FAA is revising Airworthiness Directive (AD) 2003-22-07, which applies to all Mitsubishi Heavy Industries, Ltd. (Mitsubishi) MU- 2B series airplanes. AD 2003-22-07 requires incorporating information into the Limitations Section of the Airplane Flight Manual (AFM) that requires pilot training before flight into known or forecast icing conditions after a certain date. AD 2003-22-07 resulted from the development of a new training video that includes information that is critical to safety of the MU-2B series airplanes. This AD revision is the result of the FAA incorrectly stating in the actions required by AD 2003-22-07 that on or before June 15, 2004 (the effective date of AD 2003-22-07), no person may serve as pilot-in-command (PIC) of a MU-2B series airplane in a flight into known or forecast icing conditions, unless the PIC has received the required training. Consequently, this AD will correct the actions required in AD 2003-22-07 to require those actions on or after June 15, 2004. We are issuing this AD to ensure that the Icing Awareness Training (IAT) requirement continues after June 15, 2004, in order to decrease the chance of icing-related incidents or accidents of the MU-2B series airplanes due to pilot error.

The Lancair Company Models LC40-550FG and LC42-550FG Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain The Lancair Company (Lancair) Models LC40-550FG and LC42-550FG airplanes. This AD requires you to repetitively inspect the fuel pressure transducer for evidence of chafing and measure the cross section diameter (as necessary). The AD also requires you to install a compliance kit at a time dependent on the outcomes of the inspections and measurement. Installation of the kit is terminating action for the repetitive inspection requirements. This AD is the result of several reports of the fuel pressure transducer wearing through at the threads where it attached to the fuel line. We are issuing this AD to detect and correct chafing and wear of the fuel pressure transducer, which could result in failure of the transducer threaded fitting with a resulting fuel leak. These fuel leaks could lead to engine power loss or fire.
