7.4 Annual Test
An annual test must be performed annually as described by FAR 91.207d
7.5 Corrosion Inspection
Emerging Lifesaving Technologies ELT is designed and tested to the highest environmental
testing standards. The unit is made out of a specially designed polycarbonate that is resistant to
the harshest applications in aviation today. The unit is sealed and should not allow moisture or
most chemicals or fluids to infiltrate the system.
Regular (annual) inspections should be made of the outside of the units. While it is very unlikely,
IF ANY deterioration or corrosion is found, a more detailed inspection is warranted. Return the
unit to the manufacturer for inspection.
Special Inspection during Battery Replacement
During routine battery replacement, an inspection should be made inside the battery cavity for
signs of corrosion or any residue that is out of place. Should any be found contact the
manufacturer for further instructions.
