The airworthiness directive
61-11-01 BRANTLY: Amdt. 288 Part 507 Federal Register May 23, 1961. Applies to All B-2 Helicopters.
Compliance required within the next 10 hours' time in service after effective date of this directive. A failure in the skid landing gear drag brace rod end bearing (Kahr Bearing Co. P/N HE-3SFN) occurred during ground handling resulting in collapse of the landing gear. This failure occurred through the area of the lubrication fitting.
To preclude the possibility of additional failures, check the shoulder dimension of the two (2) Kahr P/N HE-3SFN rod end bearings at the forward ends of the Brantly P/N B2-259-1 and B2-259-2 landing gear drag struts. If the dimension shown in the sketch is less than 0.5 inch, the part must be replaced before further flight with a new bearing, Brantly P/N B2-259-11, or an FAA approved equivalent.
(Brantly Service Bulletin No. 11 covers this subject. NOTE: Service Bulletin No. 11 refers to P/N B2-259-11 as "new type.")
This directive effective May 31, 1961.
