CAUTION: MANY ORIGINAL ELT INSTALLATIONS ARE INADEQUATE AS FAR AS UNIT LOCATION
AND SURFACE RIGIDITY ARE CONCERNED. BECAUSE OF THE CRITICAL FUNCTION AN
ELT PERFORMS, IT IS IMPORTANT THE INSTALLATION FOLLOWS THE INSTRUCTIONS
AND RECOMMENDATIONS HEREIN.
CAUTION: THE MOUNTING SURFACE MUST BE EXTREMELY RIGID; THEREFORE, MOUNTING AN
ELT DIRECTLY TO THE AIRCRAFT SKIN IS UNACCEPTABLE. MOUNTING THE ELT
DIRECTLY TO THE AIRCRAFT SKIN INDUCES “CRASH HIDING” VIBRATIONS AND
PROVIDES A VERY POOR MOUNTING SURFACE.
CAUTION: AVOID LOCATING THE ELT WHERE IT WILL BE SUBJECTED TO UNPROTECTED
EXPOSURE TO HARSH CHEMICAL FLUIDS SUCH AS DEICING COMPOUNDS. THESE
TYPES OF CHEMICAL FLUIDS CAN PROMOTE CRACKING AND FRACTURING OF THE
ELT MOUNTING FRAME AND HOUSING COMPONENTS BY DEGRADING THE
STRUCTURAL INTEGRITY OF THESE COMPONENTS. THESE SAME CHEMICAL AGENTS
MAY ALSO CAUSE CORROSION OF ELECTRICAL CONNECTIONS.
WARNING: AVOID LOCATING THE ELT IN SUCH A LOCATION WHERE IT MAY BE SUBJECT TO
FLYING OBJECTS OR AIRCRAFT STRUCTURAL PARTS THAT MAY IMPACT THE ELT
DURING AN AIRCRAFT CRASH. MOUNTING AN ELT IN A VULNERABLE AREA CAN
RESULT IN AN IMPACT BEYOND THE ELT'S TSO CRASH RATING OF 100G, CAUSING
DAMAGE AND PREVENTING CORRECT OPERATION DURING A POST-CRASH
ENVIRONMENT.
