As Spring gets into full swing, you may notice some unusual visitors around the hangar.  There will be two different types of Cicadas emerging at the same time this year.   Not only are these insects loud and annoying, but they can also cause damage to your aircraft.

Bombardier has issued Advisory Wire AW000-02-0005 Rev 01 that effects all Learjet, Challenger and Global model aircraft.

It has been reported the insects are attracted to the running APU and will swarm around the tail of the aircraft. The insects are then ingested into the APU inlet (see next page) and may cause damage. The reports are also citing the issues with the air-conditioning packs and ducting, causing cooling issues, odors and in some cases debris coming out of the vents and into the cabin. The ingestion of the bugs has caused damage to the combustion sections such that the APUs will have to be sent out for repair/overhaul.
