Compliance: For Group 1 aircraft: Within 100 hours time-in-service after 22 March 2001.
For Group 2 aircraft: Within 100 hours time in service after 20 March 2003, unless already accomplished.
The compliance time remains unchanged for aircraft affected by the original issue of this Directive.
This Amendment becomes effective on 20 March 2003.
Beechcraft 36 (Bonanza) Series Aeroplanes
AD/BEECH 36/48 Amdt 1 (Continued)
Background: The manufacturer has identified several instances of missing rivets on affected aircraft. These rivets must be present for the fuselage to carry the ultimate load and prevent critical structural failure, with loss of aircraft control.
Amendment 1 is issued in response to a new FAA AD which corrects aircraft applicability.
The original issue of this Airworthiness Directive became effective on 22 March 2001.

Overview
The Civil Aviation Safety Authority (CASA) introduced the Airworthiness Directive (AD) AD/BEECH 36/48, effective from 22 March 2001, to address the safety issue of missing rivets on Beechcraft 36 (Bonanza) Series Aeroplanes. This safety concern was identified by the manufacturer, who reported instances where missing rivets could result in critical structural failure, potentially leading to a loss of aircraft control. The AD was subsequently amended on 20 March 2003 to correct the aircraft applicability and update compliance timelines, reflecting a new Federal Aviation Administration (FAA) AD. The directive mandates inspections and necessary repairs to ensure the integrity and airworthiness of the affected aircraft, aligning with the overarching policy objective of maintaining high safety standards in aviation.
Scope and Application
The Airworthiness Directive (AD) AD/BEECH 36/48, issued by the Civil Aviation Safety Authority (CASA) under subregulation 39.1 (1) of the Civil Aviation Regulations 1998, applies specifically to Beechcraft 36 (Bonanza) Series Aeroplanes, identified by their serial numbers and model types. The directive mandates a comprehensive inspection of the right-hand fuselage rivets between fuselage stations (F.S.) 83.00 and F.S. 91.00 at water line (W.L.) 90.3 for all Group 1 and Group 2 aircraft. If missing rivets are detected, they must be replaced before any further flight. Group 1 aircraft must comply within 100 hours of time-in-service after 22 March 2001, while Group 2 aircraft must comply within 100 hours of time in service after 20 March 2003, unless the required action has already been undertaken. The AD extends its reach across the Commonwealth of Australia and is enforced by the Civil Aviation Safety Authority, with the directive being notified in the Commonwealth of Australia Gazette on 26 February 2003.
Key Provisions
The Airworthiness Directive (AD) issued under subregulation 39.1 (1) of the Civil Aviation Regulations 1998 (CAR 1998) specifically pertains to Beechcraft 36 (Bonanza) Series Aeroplanes. The directive (AD/BEECH 36/48 Amendment 1) focuses on addressing the issue of missing rivets between fuselage stations 83.00 and 91.00 at water line 90.3 on both Group 1 and Group 2 aircraft. The directive mandates inspections to be conducted in accordance with Raytheon Mandatory Service Bulletin SB 53-3341 Revision 1 or Revision 2 and the Bonanza Series Maintenance Manual. If any rivets are found to be missing, they must be installed before further flight.
The AD imposes specific obligations on the operators and maintainers of the affected aircraft. For Group 1 aircraft, the inspection must be carried out within 100 hours of time-in-service after 22 March 2001. For Group 2 aircraft, the inspection is required within 100 hours of time in service after 20 March 2003, unless the inspection has already been completed. Operators and maintainers must ensure compliance with these deadlines to maintain the airworthiness of the aircraft.
Failure to comply with the AD can result in serious consequences. The AD highlights that the absence of the required rivets poses a significant risk to the structural integrity of the fuselage, potentially leading to a loss of control of the aircraft. Non-compliance with the AD can be considered a breach of the CAR 1998, potentially leading to enforcement actions by the Civil Aviation Safety Authority (CASA). While the specific penalties are not detailed within the AD itself, breaches of aviation regulations can result in civil penalties, including fines, and criminal penalties, including imprisonment, depending on the severity and circumstances of the breach.
