Plain English Summary

2/10 complexity

This safety order requires operators of agricultural aircraft to inspect seat harnesses for Pacific Scientific buckle PN 1101550 (and dash variants) and remove any affected buckles from service by 31 December 1989. Investigators found the buckle’s retaining toggle may fail under crash loads, risking pilot ejection. Affected units must be made airworthy by replacing the buckle or the entire harness with an approved alternative.
