Welcome to Boeing distribution, formerly Aviall

Ontic Engineering® Altitude Clearance Memory Device 310-4

Ontic
Part # 310-4=N1

 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

 

 

Applicability:  Boeing 737-600, 737-700, 737-800, 737-900, 737-900ER, and BBJ
