Sometimes the best fire prevention you can come by in an aircraft is a good lock. Well, that’s how they think at Peerless Electronics, a New York electronics online distributor of heavy equipment and aerospace electronics components. For NBAA 2014 the company is featuring two aircraft locks that can help prevent electrical shorts. The S2329 Master Lock aircraft circuit breaker lock keeps pilots or maintenance personnel from resetting critical circuit breakers. It accommodates short or long circuit breakers. The S2029 aircraft ground power receptacle lock fits three- and six-prong power receptacles and prevents ground power plug insertion.
