First STC For Lithium Nanophosphate Batteries Granted For 30
Aircraft
The FAA has awarded an Approved Model List (AML) Supplemental
Type Certificate (STC) to Mid-Continent Instruments for the
company's MD835 Lithium Emergency Power Supply. Company officials
announced the award Tuesday.
The MD835 Emergency Power Supply is the first Lithium
Nanophosphate battery to be AML STC approved by the FAA for use in
Part 23 aircraft. This TSO C179 certified battery supplies 24.5 VDC
power for critical and standby equipment and maintains full
capacity by recharging during normal flight operations. The AML STC
includes a list of 30 aircraft, including the Beechcraft King Air
90, 200 and 300 series, Beech 1900, Beechcraft Premier and Cessna
Citation 501, 525A and B models.
"This is a great accomplishment by the Mid-Continent Instruments
team of engineers who worked on this project using state-of-the-art
technology," said Tom Genovese, director of sales. "It gives owners
of these aircraft an easy-to-install, lower-cost-of-ownership
option for their standby battery requirements."
As a direct replacement for the legacy lead-acid-powered L-3
PS-835, Mid-Continent Instruments' MD835 standby battery utilizes
the same mounting rack, wire harness and flight deck ARM/OFF/TEST
switch. This new design weighs in at 4.8 pounds - more than 8
pounds lighter than competing products. Maintenance intervals for
the MD835 are only every two years, compared with legacy lead-acid
designs' yearly capacity check. And with a life expectancy of 10
years, the MD835 easily outlasts the typical lead-acid battery's
three-year replacement schedule.
The MD835 standby battery is one in the
company's new line of True Blue Power products, which the company
says are designed and manufactured by Mid-Continent Instruments.
Current production includes aircraft inverters and emergency power
supplies, to be followed by batteries.
Mid-Continent Instruments' MD835 Emergency Power Supply is
currently available from approved avionics dealers and the
following Mid-Continent Instruments distributors: Adams Aviation
Supply Co., Avionics International Supply, Dallas Avionics, EDMO
Asia Pacific Pty. Ltd., EDMO Distributors, Global Aviation + Piper
Parts GmbH, Hawker Pacific Pty. Ltd., Merrill Field Instruments,
North American Distributors Inc., Precision Avionics &
Instruments, Precision Heliparts Inc. and Sun Aviation.
