REGULATORY TEXT:  
53-18-01 CESSNA: Applies to All Model T-50 Aircraft.

Compliance required by November 1, 1953.

As a result of reported failures of the outer bearing in the Goodrich Model 751A/M, G-3- 49A, 7.50-10 main gear assembly, each resulting in loss of a wheel, the following should be accomplished if the outer bearing has not been replaced since the airplane was converted from military to civil operation. If the outer bearing has been replaced subsequent to that time, compliance only with item 1 is required.

1. Not later than the date specified above, replace the 1 7/16-inch washer located between the axle nut and the inner bearing cone with a washer 1 7/8 inch outside diameter, 0.953 + 0.005 inch inside diameter and 0.093 + 0.005 inch thick manufactured from SAE 1010 or equivalent. This precautionary measure will not prevent bearing failure but may prevent the wheel from coming off the axle during landing in the event of a bearing failure.

2. At the time of item 1 and at every 100 hours of operation thereafter until the bearing is replaced, check wheel side movement, inspect bearing and replace bearing as necessary. Replacement should be accomplished with Timken Cone No. 07100 and Cup No. 07196 or an equivalent bearing.

(B.F. Goodrich Co. Service Bulletin No. 36, revised April 20, 1953, covers this same subject and supplies information for the fabrication of the new washer and for ordering proper replacement bearings.)
