Document Type and Number:
Japanese Patent JP2016011752
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fault tolerance design realizing spark protection and spark containment at a fastener in a flammable zone in an aircraft structure, without the need to attach a cap seal to a head of the fastener.SOLUTION: An apparatus comprises a washer 320, a sleeve 302, and a fastener 300. The washer 320 has a first channel 318. The sleeve 302 has a second channel 314 and an expandable section. The sleeve 302 is positioned inside the first channel 318 in the washer 320.
