Sometime in 2011 (we can’t be sure when), an airport worker hooked up an energized ground-power unit to a Cessna Citation CJ4 (525C), according to the FAA. The CJ4 was the first business jet certified with a lithium-ion main-ship battery.
Concorde Battery (Stand 2404) is exhibiting its range of improved lead-acid aircraft batteries. Although lead-acid is old battery technology, having been invented in 1859, it may be soon the only one available for aviation use. According to Concorde executives, nickel-cadmium batteries could be banned to protect worker health and lithium-ion models seem too hazardous for airborne applications.
The photo of a badly burned Apple iPhone that circulated after the phone caught fire during a Regional Express flight has raised important questions about lithium-ion battery safety among a wide aviation audience. The incident occurred after the Regional Express Saab 340B landed in Sydney, Australia, on Nov.
Bombardier Challenger 300 operators now have a choice of replacing the jet’s original nickel-cadmium main ship battery with a new Concorde RG-441 lead-acid battery. The FAA has awarded Concorde (Booth No. 2039) a supplemental type certificate (STC No. ST01488WI) for installation of the RG-441 lead-acid battery.
CRS Jet Spares is offering a new low-current/constant-voltage battery trickle charger that can be used to float-charge nicad and lead-acid mainship batteries. According to Armando Leighton Jr., the company’s CEO, the unit is a low-cost way to maintain the charge of batteries in storage or on aircraft so that fully charged batteries are available when needed.
Aircraft maintenance does not exactly move forward technologically at the speed of light. Instead, it appears the industry is in a constant state of making things incrementally better. A small innovation here, some modification to an existing procedure there, a reemphasis on the importance of service, and the result is that operators get better, faster, more cost-effective maintenance.
The FAA has approved eight valve-regulated sealed lead acid batteries
under Technical Standard Order C173 for Concorde Battery.
The TSO-approved models are Concorde’s RG-121 Series and RG-122 Series, emergency batteries for lighting, standby, avionics, fadec and backup power. Parts conforming to TSO C173 are approved for design and production.
Securaplane recently announced that CRS Jet Spares, a Securaplane mainship and emergency battery line distributor, has sold its 20,000th mainship battery. Securaplane emergency battery systems use Hawker sealed lead acid batteries instead of nicads and are either original or approved replacement equipment for most business jets.
The Hawker 43Ah steel case, sealed lead-acid battery has been STC’d for installation in the Embraer Brasilia. The unit was developed as a replacement for the factory-installed SAFT 4076-9 and 4078-10. It is already in use on the Bandeirante, Twin Otter and Dash 8.
