For Immediate Release

Securaplane has received PMA for installation of its ST3000 Wireless 
Smoke Detection System on Boeing 737-300 series aircraft 
for "D" to "C" class lower cargo compartment upgrade
 

On November 30, 1998, Securaplane received a Parts Manufacturer Approval 
(PMA) for its ST3000 Wireless Smoke Detection System for installation on 
Boeing 737-300 aircraft for "D" to "C" class lower cargo compartment 
upgrade.

The Securaplane wireless smoke detection system reduces installation 
time considerably from wired systems.  It can be installed on the 
aircraft during an overnight (approximately 80-100 man hours), 
significantly reducing major aircraft downtime compared to hardwired 
systems. Other advantages include comparative low cost and fast 
replacement of sensor heads or batteries (less than 10 minutes) and 
reduced weight (50-75 lbs. over a wired system).

Securaplane's wireless fire detection system eliminates single point 
failures associated with wired systems and, if desired allows monitoring 
when the aircraft is unmanned, down to the individual sensor head.  This 
system also allows wireless maintenance diagnostics external to the 
aircraft.  The Securaplane system will also provide maintenance with 
specific component status in plain English on an alphanumeric readout.

Wireless smoke detection contracts include Southwest Airlines, as well 
as UPS, Airborne Express, DHL, Emery Worldwide (J.F.A.T. Joint Freighter 
Airline Team), and Sun Country Airlines.

Securaplane is a designer and manufacturer of emergency power systems, 
main aircraft battery chargers, electronic aircraft security systems in 
addition to wireless aircraft smoke detection/reporting equipment. 
Securaplane is based in Tucson, Arizona.
