Case Study: an international airline prevents auxiliary power unit damage with SpotSee ShockLog Cellular GL

International Airline prevents 13G APU damage with SpotSee

An international airline was facing a recurring issue where the auxiliary power units (APUs) on their airplanes were being damaged in-flight. The cause and timing of these destructive impacts were unknown, leading to concerns that the APU enclosure's design was defective. The airline partnered with SpotSee and used their ShockLog Cellular GL impact monitor to investigate the problem.

SpotSee's solution involved mounting the ShockLog Cellular GL to the APU enclosure and setting its threshold to 9G. The device immediately provided data upon landing, revealing that a 13G impact occurred in the z-axis during each landing, which was 4G beyond the APU's specification. This discovery enabled the airline to write a more robust product specification and create an improved mounting solution for their APUs.
