AIRWORTHINESS DIRECTIVE
For the reasons set out in the background section, the CASA delegate whose signature appears below issues the following Airworthiness Directive (AD) under subregulation 39.1 (1) of CAR 1998. The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.
Beechcraft 200 (Super King Air) Series Aeroplanes
AD/BEECH 200/68 KA-33 Cooling Blower 8/2001
Applicability: Beech Model B200, serial numbers BB-1314, BB-1449 through BB-1692 inclusive, equipped with Collins EFIS-84 System.
Requirement: 1. Install an in-line fuse holder, part number (P/N) HHJ-A, and install a one ampere slow-blow fuse, P/N MDL1, in the fuse holder, in accordance with either Raytheon Mandatory Service Bulletin SB 34-3269, issued January 2000 or Revision 1, revised October 2000.
2. Remove the fuse P/N GMW-1 from the Avionics Junction Box and install a new fuse P/N GMW-3, in accordance with either SB 34-3269 or SB 34-3269 Revision 1.
Note: FAA AD 2001-11-03 Amdt 39-12244 refers.
Compliance: For Requirement 1 - Within the next 600 hours time-in-service after the effective date of this Directive or the next six calendar months after the effective date of this Directive, whichever occurs first.
For Requirement 2 - Within the next 600 hours time-in-service after the effective date of this Directive or the next six calendar months after the effective date of this Directive, whichever occurs first.
This Airworthiness Directive becomes effective on 9 August 2001.
Background: The United States Federal Aviation Administration has received several reports of blower motors failing, seizing, smoking, and producing a burning odour that enters the cabin and passenger compartment. These events are the result of the blower motor having circuit protection of more than one ampere. This level of circuit protection does not prevent the blower motor from smoking and creating a burning odour should it fail or seize.

AD/BEECH 200/68 (Continued)
This Directive introduces measures intended to protect the blower motor circuit and reduce the possibility of emission of smoke or a burning odour into the cockpit or passenger compartment.

The above AD is notified in the Commonwealth of Australia Gazette on 11 July 2001.
Overview
The Airworthiness Directive (AD) AD/BEECH 200/68, issued on 8 August 2001 by the Civil Aviation Safety Authority (CASA), addresses safety concerns regarding the cooling blower system in Beechcraft 200 (Super King Air) Series aeroplanes, specifically models B200 with serial numbers BB-1314, BB-1449 through BB-1692 inclusive, equipped with the Collins EFIS-84 System. The directive was enacted in response to multiple reports of blower motor failures, seizing, smoking, and burning odours entering the cabin and passenger compartment, which were attributed to inadequate circuit protection. This AD aims to mitigate these risks by requiring the installation of specific fuses and components to safeguard the blower motor circuit and prevent the emission of smoke or burning odours into the cockpit or passenger compartment. Compliance with the directive must be achieved within 600 hours of time-in-service or six calendar months from the effective date, whichever comes first.
Scope and Application
The Airworthiness Directive (AD) AD/BEECH 200/68 issued by the Civil Aviation Safety Authority (CASA) applies specifically to Beechcraft Model B200 aeroplanes, serial numbers BB-1314, BB-1449 through BB-1692 inclusive, that are equipped with Collins EFIS-84 System. This AD mandates specific actions to address safety concerns associated with the aircraft's cooling blower system, as identified by reports of blower motor failures. The requirement outlined in the AD includes the installation of a one ampere slow-blow fuse in an in-line fuse holder, as well as the replacement of a particular fuse within the Avionics Junction Box, both of which are to be carried out in accordance with specified service bulletins. Compliance with these requirements must be achieved within 600 hours of time-in-service or six calendar months from the effective date of the AD, whichever is sooner. This directive is applicable on a national level within Australia and was issued to ensure the safety of the mentioned aircraft models by mitigating potential hazards associated with blower motor failures.
Key Provisions
The Airworthiness Directive (AD) specified in AD/BEECH 200/68 (section 1) applies to Beech Model B200 aircraft with serial numbers BB-1314, BB-1449 through BB-1692 inclusive, that are equipped with the Collins EFIS-84 System (section 2). The AD requires the installation of an in-line fuse holder, part number HHJ-A, and a one ampere slow-blow fuse, part number MDL1, in accordance with either Raytheon Mandatory Service Bulletin SB 34-3269, issued January 2000 or Revision 1, revised October 2000 (section 3(1)). Additionally, the AD mandates the removal of the fuse part number GMW-1 from the Avionics Junction Box and the installation of a new fuse part number GMW-3, again in accordance with either SB 34-3269 or SB 34-3269 Revision 1 (section 3(2)). The compliance period for both requirements is within the next 600 hours time-in-service after the effective date of this Directive or the next six calendar months after the effective date of this Directive, whichever occurs first (section 4).
Operators and owners of the specified Beechcraft 200 (Super King Air) Series Aeroplanes must ensure that the actions outlined in the AD are carried out within the stipulated compliance period. This involves installing the specified in-line fuse holder and one ampere slow-blow fuse and replacing the existing fuse in the Avionics Junction Box with the new fuse. Failure to comply with these requirements could result in the aircraft being deemed unairworthy, which would prevent it from operating legally until the necessary actions are taken.
Failure to comply with the requirements of this Airworthiness Directive may result in civil or criminal consequences. The Civil Aviation Safety Authority (CASA) may take enforcement actions against operators or owners who fail to adhere to the AD. This could include fines, the suspension or revocation of an operator's certificate, or other regulatory actions. The exact penalties and consequences will depend on the specific circumstances of the non-compliance and the discretion of the CASA delegate.
