AD/BEECH 33/41
Amdt 1
Wing Bolt, Nut and Fitting 2/2002
Applicability: All models.
Requirement: 1. Remove and inspect wing bolts, washers, nuts and fittings in accordance with Beechcraft Shop Manual 33-590011-1C17 Section 4 or Maintenance Manual 36- 590001-9A17 Section 57-00-00.
2. Retire wing bolts, washers and nuts from service and replace with new hardware in accordance with Beechcraft Shop Manual 33-590011-1C17 Section 4 or Maintenance Manual 36-590001-9A17 Section 57-00-00. Render unserviceable all hardware retired.
Note: The bolt torque should be checked before replacement to confirm bolt has been torqued to correct value. If the torque value is incorrect, other maintenance action may be required.
Compliance: 1. Unless inspection has already been accomplished in accordance with the Requirement Document, initially inspect before 5 calendar years from initial installation, or within 100 hours time in service after 1 February 1996, whichever occurs later. Re-inspect at intervals not to exceed 5 calendar years.
2. Retire before 15 calendar years after initial installation, or within 100 hours time in service after 1 February 1996, whichever occurs later.
Where date of initial installation is unknown, the date of manufacture of the aircraft must be used for paragraphs 1 and 2.
This amendment becomes effective on 21 February 2002.
Background: This AD makes mandatory the inspection and replacement periods for the wing attachment hardware detailed in the Requirement Document.
Amdt 1 - Adds the Note to requirement 2 and adds the fittings as an item to be inspected when the wing bolts, washers and nuts are removed and inspected.

Eugene Paul Holzapfel
Delegate of the Civil Aviation Safety Authority 3 January 2002
The above AD is notified in the Commonwealth of Australia Gazette on 30 January 2002.
Overview
The Civil Aviation Safety Authority (CASA) issued the Airworthiness Directive (AD) AD/BEECH 33/41 Amendment 1 in 2002 to address safety concerns related to the wing bolt, nut, and fitting hardware of the Beechcraft 33 and 35-33 (Debonair/Bonanza) Series aeroplanes. This legislative instrument was enacted under the Civil Aviation Act 1988 to ensure that the specified aircraft parts are inspected and replaced at regular intervals to mitigate the risk of unsafe conditions. The directive revokes the previous AD AD/BEECH 33/41 and introduces new inspection and replacement requirements for the wing bolts, washers, nuts, and fittings, with the aim of ensuring the continued airworthiness of these aircraft by maintaining the integrity of their structural components.
Scope and Application
The Airworthiness Directive (AD) issued under the Civil Aviation Regulations 1998 (CAR 1998) pertains specifically to Beechcraft 33 and 35-33 (Debonair/Bonanza) Series Aeroplanes, applying to all models of these aircraft. The directive mandates the inspection, replacement, and retirement of wing bolts, washers, nuts, and fittings to address an identified unsafe condition. The AD applies to any person or entity involved in the maintenance, operation, or ownership of these aircraft within the Commonwealth of Australia. Compliance with the AD is mandatory, and failure to adhere to the specified inspection and replacement intervals can result in the aircraft being deemed unairworthy. The AD became effective on 21 February 2002, and its requirements must be met by all relevant parties in accordance with the timelines provided. The directive includes specific instructions for the inspection and replacement process, referencing the Beechcraft Shop Manual and Maintenance Manual for detailed procedures. The AD does not specify any exclusions or exemptions, implying that all affected aircraft must comply without exception. The application of the AD is further extended or restricted through subordinate instruments as necessary, ensuring that safety standards are consistently met across the aviation industry.
Key Provisions
This Airworthiness Directive (AD) issued under the Civil Aviation Regulations 1998 (CAR 1998) focuses on the maintenance and replacement of wing bolts, washers, nuts, and fittings for Beechcraft 33 & 35-33 (Debonair/Bonanza) Series Aeroplanes. According to section 1, the AD requires all models of the specified aircraft to undergo a mandatory inspection and replacement process for these critical components. The inspection and replacement must be carried out in accordance with the instructions provided in either the Beechcraft Shop Manual 33-590011-1C17 Section 4 or the Maintenance Manual 36-590001-9A17 Section 57-00-00. Additionally, all retired hardware must be rendered unserviceable. The AD also notes that the bolt torque should be checked before replacement to ensure it meets the correct value, with the potential need for additional maintenance if the torque is incorrect.
The AD imposes several obligations on the parties and entities it governs. Firstly, all models of the specified aircraft must undergo an initial inspection within five calendar years from the initial installation or within 100 hours of time in service after 1 February 1996, whichever occurs later. If the inspection has already been completed in accordance with the Requirement Document, this initial inspection is not required. The AD also mandates that the wing bolts, washers, and nuts be retired before 15 calendar years after the initial installation or within 100 hours of time in service after 1 February 1996, whichever occurs later. If the date of initial installation is unknown, the date of manufacture of the aircraft should be used. These obligations aim to ensure the ongoing airworthiness of the affected aircraft by addressing potential safety issues related to the wing attachment hardware.
Failure to comply with the provisions of this AD may result in various consequences. Although the text does not explicitly state the penalties for non-compliance, it is essential to note that the Civil Aviation Safety Authority (CASA) has the authority to enforce compliance with ADs. Non-compliance with ADs can lead to civil or criminal penalties, including fines and imprisonment, depending on the severity of the breach and any associated safety risks. It is crucial for aircraft operators and maintenance personnel to adhere to the requirements of this AD to maintain the airworthiness of the affected aircraft and avoid potential legal consequences.
