The airworthiness directive
61-20-03 RUSSELL MANUFACTURING COMPANY SAFETY BELT: Amdt. 337 Part 507 Federal Register September 20, 1961. Applies to All Aircraft Equipped With Rusco Model RM23 P/N SB1709 Safety Belts Manufactured From October 1959, through June 1960, and Equipped With D-832B Buckles.
Compliance required with the next 25 hours' time in service after the effective date of this directive.
Service difficulties with Rusco Model RM23, P/N SB1709, safety belt assemblies manufactured from October 1959, through June 1960, have been reported wherein the buckle cam does not securely grip the webbing thereby causing the assembly to slip.
In order to determine the airworthiness of these belts, a minimum tensile load of 100 pounds must be applied to the belt assembly. If the webbing slips through the buckle as a result of this test, the belt must be considered unairworthy and replaced with an airworthy belt assembly conforming to TSO-C22 standards prior to further flight.
(Russell Manufacturing Company Bulletin No. 61-5 covers this same subject.)
This directive effective October 20, 1961.
