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.
Peerless Electronics is now distributing the full line of Master Lock aviation safety products, including the new aircraft circuit breaker lockout/tagouts. The S2329 Master Lock aircraft circuit breaker lockout prevents accidental re-energizing of an electrical system by locking a circuit breaker in the “off” position. They assist in FAA and OSHA compliance for lockout/tagout (aircraft LOTO) systems. S2329’s universal fit accommodates long or short aircraft circuit breakers, with or without collars and with three- and six-prong power receptacles.
The FAA has issued a notice of proposed rulemaking on an airworthiness directive (AD) for the Dassault Falcon 50 slat system. It is prompted by an intermittent indication of slat activity caused by chafing of the electrical wiring.
Three business aircraft manufacturers have selected Astronics Advanced Electronic Systems EmPower dual-use AC/USB outlets for passengers and crew. The dual-use 1295-8-XX outlet provides both a 115-VAC, 60-Hz and a 5-VDC, 2.1-amp USB socket, which can be used simultaneously. The 115 VAC socket accepts plugs from more than 155 countries and features a third ground to the aircraft structure. Internal LEDs make the plugs easy to find in a dark cabin or cockpit, and status lights indicate whether power is available for each socket.
Newly issued airworthiness directive AD 2013-03-07 for the Hawker 400A was prompted by a report that the cockpit wiring for the 5-volt direct current (DC) system on the aircraft is undersized and does not have adequate circuit protection for the smaller gauge wire. The directive, which is effective as of March 19, requires installation of an in-line fuse in the 5-volt DC system for each of the five instrument lighting control power supplies.
The FAA has issued an Airworthiness Directive for the AgustaWestland A109S requiring the modification of the electrical power distribution system to carry a higher electrical load. It was prompted by an electrical failure that resulted from inadequate functioning of the 35 amperes “Batt Bus” circuit breaker.
The FAA plans to issue Airworthiness Directive FAA-2012-1111 to address wiring issues on the Beechjet 400A. The AD was prompted by a report that the wiring for the five-volt direct-current system is undersized and does not have adequate circuit protection for the smaller-gauge wire. This proposed AD would require installing an in-line fuse in the five-volt DC system for each of the five instrument lighting control power supplies.
The FAA is adopting a new Airworthiness Directive–2012-CE-026-AD–for 35 Hawker Beechcraft C90GTi King Air twin turboprops. This AD was prompted by reports of incorrect gauge wires used in certain wiring bundles for the cockpit electrical power for backlighting and instrument panel components. This AD requires replacing the incorrect wiring bundles, inspecting associated wiring bundles and components for heat damage, and taking all necessary corrective actions. The new AD becomes effective Nov. 27, 2012.

New Part 121 regulations require significant electrical wiring interconnect systems (EWIS) training for technicians and inspectors. Global Jet Services has developed the Practical Aircraft Wiring course for Group 1 (Maintenance Personnel-Repairs), Group 2 (Inspection Personnel) and Group 4 (Maintainers-removal & installation of equipment).
