Plain English Summary

4/10 complexity

This Airworthiness Directive requires operators of specified Beechcraft 33/35 (Debonair/Bonanza) aeroplanes to inspect the landing-gear up‑lock rollers, replace any solid (non‑greasable) rollers with greasible types, fit hollow zerk‑ended mounting bolts, and begin recurring lubrication per Beechcraft Service Instructions. Initial replacement/inspection actions must occur within about 100 hours time‑in‑service, with lubrication repeated at roughly 100±10 hour intervals.

It affects owners/operators of the listed models and serial numbers, who must fund parts, labour and the ongoing maintenance to reduce the risk of gear‑up landings from roller seizure.

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 numbersCD-1 through CD-1256, inclusive; andModels 35-C33A, E33A, and F33A serial numbers CE-1 through CE-349, inclusive; andModels 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.

Background:	This AD results from a recent incident involving a Beechcraft Model 95-B55B(T-42A) airplane where a seizure of the uplock rollers occurred. The Requirements of this AD are aimed at decreasing the possibility of gear-up landings caused by seizure of the up-lock rollers.
