The locking plates shown in the illustration are used in many marine applications. Which figure indicates the improper method for using these devices? GS-0156

Correct Answer: Option D — "C"

Figure C illustrates an improper installation where the locking plate tabs are not correctly bent or secured against the fastener flats. Proper locking plate application is mandatory under marine maintenance standards to prevent vibration-induced loosening of critical bolts, which could lead to catastrophic machinery failure at sea.
