Summary of the Problem.
a. Testing of aircraft aircrew restraint system has revealed a potential for the Pacific--Scientific
manufactured restraint system adjusters to fail (slip) at high loads but below those designated in the
military specification, MIL--S--58095A. The adjusters' failure (slipping) may allow the seat occupant to
make contact with surrounding equipment or structure during an accident sequence. As such,
replacement assets will be provided to the applicable and appropriate facilities in direct exchange for the
subject items.
b. For manpower/downtime and funding impacts -- See paragraph 12.
c.
The purpose of this TB is to identify Pacific--Scientific Restraint Systems for recall items.
