The airworthiness directive
61-16-03 BRANTLY: Amdt. 317 Part 507 Federal Register August 4, 1961. Applies to All B-2 Helicopters Prior to Serial No. 104.
Compliance required within the next 25 hours' time in service after the effective date of this AD.
Three accidents have resulted from the restriction of collective control due to interference by the seat. This interference is caused by improper seat installation which allows the seat to slide forward of its normal position. To minimize the possibility of restriction to the collective control by the seat, all Brantly B-2 helicopters prior to Serial No. 104 shall have the left hand seat angle at the rear of each seat modified to incorporate seat safety brackets, Brantly P/N 163-22 or equivalent.
(Brantly Service Bulletin No. 13, dated June 8, 1961, pertains to this same subject.)
