AIRWORTHINESS DIRECTIVE
Beechcraft 33 Debonair · Airworthiness Directives
Overview
This Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority (CASA) addresses safety concerns related to the landing gear up-lock mechanism in Beechcraft 33 and 35-33 series aircraft. The directive outlines specific requirements to ensure the safe operation of these aircraft by addressing potential failures in the up-lock rollers that could lead to gear-up landings. The AD mandates inspections and replacements of certain components within specified time frames to mitigate risks associated with the landing gear system. Compliance with this directive is crucial for maintaining airworthiness and ensuring pilot and passenger safety.
- The AD applies to Beechcraft 33 and 35-33 series aircraft.
- Inspect up-lock rollers to determine if they are greasible within 100 hours TIS after the effective date.
- Replace any non-greasible up-lock rollers with greasible types.
- Lubricate the up-lock mechanism initially within 100 hours TIS and thereafter at intervals not exceeding 100 hours TIS.
- This AD became effective on 7 June 2007.

Applicability
The AD applies to various models of Beechcraft aircraft, specifically the 33 and 35-33 series, including models 35-33, 35-A33, 35-B33, 35-C33, E33, F33, G33, and others, covering serial numbers from CD-1 through CD-1256, CE-1 through CE-349, and CJ-1 through CJ-30.
Requirements
The directive requires several actions to be taken regarding the up-lock mechanism. These include determining if the up-lock rollers are greasible, replacing non-greasible rollers, installing hollow zerk-ended mounting bolts, and lubricating the up-lock mechanism. Specific instructions are provided in Beechcraft Service Instructions No. 0448-211.
Compliance
Compliance with the AD is required within specified time frames: actions must be completed within 100 hours time in service (TIS) after the effective date of the AD, and lubrication must be performed initially within 100 hours TIS and then at intervals not exceeding 100 hours TIS thereafter.
Background
The AD was prompted by an incident involving a Beechcraft Model 95-B55B where a seizure of the uplock rollers occurred. The directive aims to reduce the risk of gear-up landings caused by this issue.
Safety notes
- Failure to comply with the AD may result in unsafe landing gear conditions, increasing the risk of gear-up landings.

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 33 and 35-33 (Debonair/Bonanza) Series Aeroplanes AD/BEECH 33/45 Landing Gear Up-lock Mechanism 6/2007 Applicability: Beechcraft (Debonair/Bonanza) aircraft: Models 35-33, 35-A33, 35-B33, 35-C33, E33, F33, and G33 serial numbers CD-1 through CD-1256, inclusive; and Models 35-C33A, E33A, and F33A serial numbers CE-1 through CE-349, inclusive; and Models E33C and F33C serial numbers CJ-1 through CJ-30, inclusive. Requirement: Using the information contained in Beechcraft Service Instructions (SI) No. 0448-211 at any FAA approved revision status: 1. Determine if each up-lock roller is of the greasible type (one having a drilled and grooved inner race). 2. Replace any non-greasible up-lock roller (one having a solid inner race) with the greasible type. 3. Install hollow zerk-ended mounting bolts on the up-lock rollers. 4. Lubricate the up-lock mechanism. Note: FAA 2007-08-08 Amendment 39-15025 dated 06 April 2007 refers. FAA AD 2007-08-08 supersedes FAA AD 72-22-01 Amendment 39-1544. Compliance: 1. Unless already accomplished, within 100 hours time in service (TIS) after the effective date of this AD. 2. Before further flight, after the determination required by Requirement 1 of this AD. 3. Unless already accomplished, within 100 hours TIS after the effective date of this AD. 4. Unless already accomplished, initially within 100 plus/minus 10 hours TIS, and repetitively thereafter, at intervals not to exceed 100 plus/minus 10 hours TIS. This Airworthiness Directive becomes effective on 7 June 2007.
