This AD requires updating the software version of the yaw servo. The FAA is issuing this AD to address the unsafe condition on these products.

Airworthiness Directives; Hawker Beechcraft Corporation Models B300 and B300C (C-12W) Airplanes

We are adopting a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation Models B300 and B300C (C-12W) airplanes. This AD was prompted by an error found in the take-off speeds and field lengths published in the FAA-approved airplane flight manual. This AD requires a correction to the published data in the airplane flight manual and the pilot's operating handbook to ensure it corresponds with the published data in the pilot's checklist. This condition, if not corrected, could result in a pilot taking off from shorter runways than required by the airplane if the airplane loses an engine after takeoff decision speed (V<INF>1</INF>). This could result in the airplane running out of runway before take-off can be accomplished. We are issuing this AD to correct the unsafe condition on these products.

Airworthiness Directives; Hawker Beechcraft Corporation Models B200, B200GT, B300, and B300C Airplanes

We are superseding an existing airworthiness directive (AD) for the products listed above. That AD currently requires fabricating and installing a placard incorporating information that limits operation when there is known or forecast icing and requires replacing a section of the pneumatic supply tube for the tail deice system with a new tube of a different material. This AD requires fabricating and installing a placard incorporating information that limits operation when there is known or forecast icing and requires replacing the entire length of the pneumatic supply tube for the tail deice system with a new tube of a different material. This AD was prompted by reports of two failures of the pneumatic supply tube for the tail deice system outside the area covered by AD 2008-07-10. We are issuing this AD to prevent collapsed pneumatic supply tubes, which could result in failure of the tail deice boots to operate. This failure could lead to loss of control in icing conditions.

Airworthiness Directives; Hawker Beechcraft Corporation (Type Certificate Previously Held by Raytheon Aircraft Company) Models B300 and B300C Airplanes

We are adopting a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation (type certificate previously held by Raytheon Aircraft Company) Models B300 and B300C airplanes. This AD requires you to inspect the terminal board on the circuit card rack assembly to determine if the correct bus bar is installed and replace if necessary. This AD also requires you to do an operational check of the left and right pitot heat annunciators for proper operation and take corrective action as necessary. This AD results from reports of the left and right pitot heat annunciators not illuminating for an inoperative pitot heat condition. We are issuing this AD to detect and correct installation of an incorrect bus bar, which could result in failure of the pitot heat annunciators to illuminate. This failure could lead to the pilot being unaware that moisture has frozen on the pitot tube(s) and cause erroneous flight instrument indication.

Airworthiness Directives; Hawker Beechcraft Corporation (Type Certificate (TC) No. 3A20 and TC No. A24CE Formerly Held by Raytheon Aircraft Corporation and Beech) Models C90A, B200, B200C, B300, and B300C Airplanes

We are adopting a new airworthiness directive (AD) that supersedes AD 2006-23-02, which applies to certain Hawker Beechcraft Corporation (HBC) (Type Certificate (TC) No. 3A20 and TC No. A24CE formerly held by Raytheon Aircraft Corporation and Beech) Models C90A, B200, B200C, B300, and B300C airplanes. AD 2006-23-02 currently requires you to inspect the flight controls for improper assembly or damage, and if any improperly assembled or damaged flight controls are found, take corrective action. Since we issued AD 2006-23-02, we have determined the need to add airplane serial numbers that were not previously included in the applicability. Consequently, this AD retains the actions of AD 2006-23-02 and adds airplane serial numbers to the applicability. We are issuing this AD to detect and correct improperly assembled or damaged flight controls, which could result in an unsafe condition by reducing capabilities of the flight controls and lead to loss of control.

Airworthiness Directives; Raytheon Aircraft Company Model B300 Airplanes

We are adopting a new airworthiness directive (AD) for certain Raytheon Aircraft Company (RAC) Model B300 airplanes. This AD requires you to modify the cabin passenger seats by installing a modification kit on each passenger seat, removing the existing technical standard order (TSO) label, and re-identifying each modified passenger seat assembly with a new part number. This AD results from the seats not meeting the ultimate load requirements of 14 CFR part 23 during structural testing of the seat with design changes. We are issuing this AD to prevent the passenger seats from failing during emergency landing conditions when high inertial loadings occur. Passenger seat failure may result in occupant injury.

Airworthiness Directives; Raytheon Aircraft Company Beech 100, 200, and 300 Series Airplanes

The FAA adopts a new airworthiness directive (AD) to supersede AD 93-25-07, which applies to Raytheon Aircraft Company (Raytheon) Beech 100, 200, and 300 series airplanes. AD 93-25-07 currently requires you to repetitively inspect the fuselage stringers for cracks and modify at certain times depending on the number of cracked stringers. This AD is the result of FAA's policy (since 1996) to not allow airplane operation when known cracks exist in primary structure. The fuselage structure is considered primary structure and operation is currently allowed for a certain period of time if less than five fuselage stringers are cracked. Consequently, this AD retains the inspection and modification requirements of AD 93-25-07, but requires you to repair any cracked fuselage stringers. We are issuing this AD to detect and correct any cracked fuselage stringers in the rear pressure bulkhead area, which could result in structural damage to the fuselage. This damage could lead to failure of the fuselage with potential loss of control of the airplane.

Airworthiness Directives; Raytheon Aircraft Company 90, 99, 100, 200, and 300 Series Airplanes

The FAA is adopting a new airworthiness directive (AD) to supersede (AD) 98-15-13, which applies to certain Raytheon Aircraft Company 90, 100, 200, and 300 series airplanes. This AD adds the Raytheon Beech 99 series to the applicability listed in AD 98-15-13. The compliance actions remain the same for those aircraft originally affected by AD 98-15-13. AD 98-15-13 currently requires you to check the airplane maintenance records from January 1, 1994, up to and including the effective date of that AD, for any MIL-H-6000B fuel hose replacements on the affected airplanes; inspecting any replaced rubber fuel hose for a spiral or diagonal external wrap with a red or orange- red stripe along the length of the hose with 94519 printed along the stripe; and replacing any MIL-H-6000B rubber fuel hose matching this description with an FAA-approved hose having a criss-cross or braided external wrap. We are issuing this AD to prevent fuel flow interruption, which could lead to uncommanded loss of engine power and loss of control of the airplane.

This amendment adopts a new airworthiness directive (AD) that applies to certain Raytheon Aircraft Company (Raytheon) 65, 90, 99, 100, 200, and 300 series, and Model 2000 airplanes. This AD requires you to install new exterior operating instruction placards for the airstair door and emergency exits. This AD is the result of Raytheon improving the visibility and understandability of the door operating instruction placards. This was done as a result of difficulty opening the emergency exits of a similar type design airplane. The actions specified by this AD are intended to assure that clear and complete operating instructions are visible for opening the airstair door and emergency exits. If the operating instructions are not visible or understandable, this could result in the inability to open the airstair door or emergency exits during an emergency situation.

Airworthiness Directives; Raytheon Aircraft Company Beech Models C90A, B200, B300, and 1900D Airplanes

This amendment adopts a new airworthiness directive (AD) that applies to all Raytheon Aircraft Company (Raytheon) Beech Models C90A, B200, B300, and 1900D airplanes. This AD requires replacing the landing gear hand pump for airplanes that had a pump within a certain serial number range installed at manufacture; and prohibits the future installation of any of these pumps on all of the affected airplanes. This AD is the result of information from the manufacturer of improper machining of the pump housing on certain landing gear emergency hand pumps on the affected airplanes. This resulted in an insufficient groove depth to retain a snap ring, which retains the check valve in its proper position within the housing. The actions specified in this AD are intended to detect any improperly machined landing gear emergency hand pumps, which, if not removed from service, could result in the inability to properly lower and lock the landing gear in the event of failure of the primary retraction/extension system.
