Cessna Service Letter SEL-24-03

Description: HET has discovered that a group of HET p/n ASG12000 (Cessna p/n 9910592) alternators may have an interference condition between the drive end housing and the slip ring end housing. This condition may prevent proper retention of the stator assembly, which may allow the stator to contact rotating components. Moderate to severe contact may disable the alternator.

Compliance: Recommended: This service letter should be accomplished at the next oil change or annual-type inspection, whichever occurs first.
