The airworthiness directive
61-20-01 AUTO CRAT MANUFACTURING COMPANY SAFETY BELT: Amdt. 341 Part 507 Federal Register September 23, 1961. Applies to All Aircraft Equipped With Auto Crat Model BN 1-1700 Series Safety Belts.
Compliance required within the next 25 hours' time in service after the effective date of this AD.
It has been determined by static test that the Auto Crat safety belt Model BN 1-1700 assemblies manufactured under Technical Standard Order C22 standards do not meet the minimum strength requirements of this TSO. Accordingly, these belt assemblies must either be replaced with belt assemblies that conform to TSO-C22 standards, or be reworked to incorporate a steel frame buckle BN 1-2000AW supplied by Auto Crat, or equivalent. When this steel frame buckle is installed, the modified belt assembly becomes Model BN 1-2000, which meets the TSO requirements and shall be marked with the new model number.
(Auto Crat letters to various air carriers dated May 10, 1961, pertains to the same subject.)
This directive effective October 24, 1961.
