Overview

Ontic Memory Wheel The Ontic memory wheel has been newly designed with increased reliability to help prevent smoke release.  The new design insulates the power input terminals using a mylar film fitted at the interior base of the unit, while potting the bottom area with a high viscosity potting material. Boeing recommends operators replace the existing (310-1, 310-2 and 310-3) memory wheels with P/N 310-4 to improve reliability and help prevent smoke release.  See Boeing Service Letter 737-SL-33-073
