Beechcraft 1900 Series Aeroplanes
AD/BEECH 1900/45 Engine Controls Cross Shaft 11/2004
Applicability: Raytheon (Formely Beech) model 1900, 1900C, and 1900D aeroplanes having serial numbers as detailed in Raytheon Aircraft Company Mandatory Service Bulletin No. SB 73–3634, dated September 2003.
Requirement: 1. Inspect the engine controls/cross shaft/pedestal for proper installation and carry out a torque check of the attach bolts, in accordance with Part I, Accomplishment Instructions of Raytheon Aircraft Company Mandatory Service Bulletin No. SB 73–3634.
2. If any improper installation or wrong torque is found during any inspection required by Requirement 1 of this Directive, correct the installation or torque in accordance with Part I, Accomplishment Instructions of Raytheon Aircraft Company Mandatory Service Bulletin No. SB 73–3634.
3. Unless previously accomplished modify the pedestal and replace the engine controls cross shaft hardware in accordance with Part II, Accomplishment Instructions of Raytheon Aircraft Company Mandatory Service Bulletin No. SB 73-3634.
Modification of the pedestal and replacement of the engine controls cross shaft hardware is the terminating action for the repetitive inspection and re-torque requirements specified in Requirement 1 of this Directive.
Note 1: FAA AD 2004-17-02 Amdt 39-13774 refers.
Note 2: The aeroplane maintenance manual also addresses the issues detailed in Requirements 1,2 and 3 of this Directive.
Compliance: For Requirement 1: Initially inspect within the next 50 hours time-in-service (TIS) after the effective date of this Directive, unless already done within the last 50 hours TIS, and thereafter at intervals not to exceed 100 hours TIS until the modification in Requirement 3 of this Directive is done.
For Requirement 2: Before further flight.
For Requirement 3: At the next scheduled Maintenance/inspection interval or 12 calendar months after the effective date of this Directive, whichever occurs later.
Beechcraft 1900 Series Aeroplanes
AD/BEECH 1900/45 (continued)
You may do this modification before this time as terminating action for the repetitive inspection and retorque requirements.
This Airworthiness Directive becomes effective on 28 October 2004.
Background: This Directive is the result of numerous reports of loose bolts on the pedestal attachment of the throttle/prop cross shaft assembly. The requirements detailed in this Directive are to detect and correct loose bolts not securing the pedestal cross shaft, which could result in limited effectiveness of the control levers. This failure could lead to an aborted takeoff.

Overview
The Airworthiness Directive (AD) AD/BEECH 1900/45 was enacted in 2004 by the Civil Aviation Safety Authority (CASA) under the Civil Aviation Safety Regulations 1998 (CASR). This AD was introduced to address safety concerns arising from reports of loose bolts on the pedestal attachment of the throttle/prop cross shaft assembly in Beechcraft 1900 Series Aeroplanes. The directive aims to ensure the proper installation and torque of the attach bolts to prevent issues that could lead to limited effectiveness of control levers and potentially result in an aborted takeoff. Compliance with this AD is mandatory for Raytheon (formerly Beech) model 1900, 1900C, and 1900D aeroplanes with specific serial numbers, as detailed in Raytheon Aircraft Company Mandatory Service Bulletin No. SB 73–3634.
Scope and Application
The Airworthiness Directive AD/BEECH 1900/45 applies specifically to Raytheon (formerly Beech) model 1900, 1900C, and 1900D aeroplanes with serial numbers detailed in Raytheon Aircraft Company Mandatory Service Bulletin No. SB 73–3634, dated September 2003. This directive mandates actions to correct an unsafe condition identified in the engine controls cross shaft, ensuring proper installation and torque of the attach bolts. The AD is issued by a delegate of the Civil Aviation Safety Authority under subregulation 39.1(1) of the Civil Aviation Safety Regulations 1998. The directive requires inspections and modifications to be carried out by operators of the specified aircraft models, with the modifications and inspections to be performed at specified intervals and before further flight if any issues are detected. The AD is effective from 28 October 2004 and outlines clear timelines for compliance, including an initial inspection within the next 50 hours time-in-service after the directive's effective date and subsequent inspections at intervals not exceeding 100 hours time-in-service until the specified modifications are completed.
Key Provisions
The main sections of the Airworthiness Directive (AD/BEECH 1900/45) detail the requirements for specific maintenance and modification actions on Raytheon (formerly Beech) model 1900, 1900C, and 1900D aeroplanes. These sections outline the specific actions that must be taken to ensure the safe operation of the aircraft. Firstly, under Requirement 1, the directive mandates that the engine controls cross shaft and pedestal be inspected for proper installation and that a torque check be conducted on the attach bolts in accordance with the instructions in Raytheon Aircraft Company Mandatory Service Bulletin No. SB 73–3634. Secondly, Requirement 2 specifies that if any improper installation or incorrect torque is detected during the inspection, corrective action must be taken in line with the same service bulletin. Thirdly, Requirement 3 requires the modification of the pedestal and replacement of the engine controls cross shaft hardware, again as per the instructions in the service bulletin. This modification serves as the terminating action for the repetitive inspection and re-torque requirements specified in Requirement 1.
The obligations imposed on the parties governed by this AD are clear and detailed. The directive requires that inspections and modifications be carried out in accordance with specific instructions from the Raytheon Aircraft Company Mandatory Service Bulletin No. SB 73–3634. The inspections must be performed within the first 50 hours time-in-service (TIS) after the AD's effective date, unless they have already been completed within the last 50 hours TIS. These inspections must then be conducted at intervals not exceeding 100 hours TIS until the modification in Requirement 3 is completed. Any necessary corrective actions under Requirement 2 must be taken before further flight. The modification under Requirement 3 must be performed at the next scheduled maintenance/inspection interval or within 12 calendar months from the AD's effective date, whichever is later. The AD allows for these modifications to be performed earlier as a terminating action for the repetitive inspection and re-torque requirements.
The consequences for non-compliance with this AD can be significant. Although specific penalties are not detailed in the text, non-compliance with airworthiness directives issued by the Civil Aviation Safety Authority (CASA) can lead to severe penalties under the Civil Aviation Act 1988 and Civil Aviation Regulations 1988 (CAR). These penalties can include fines, imprisonment, or both, depending on the severity of the non-compliance and its impact on aviation safety. Operators and owners of affected aircraft must ensure that they adhere to the AD's requirements to avoid potential legal and safety repercussions.
