INTRODUCTION

To assure the availability of the most up-to-date information concerning Honeywell gas turbine engines, a full range of technical publications are maintained current and distributed to each user. These publications are periodically updated by means of a revision or reissue to incorporate new methods and equipment. In addition, as the need arises, supplementary data is published containing recommended procedures, equipment modernization or general information in the form of manuals, service bulletins, service letters, maintenance alert notices and operating information letters.

This GTE Index is a listing of current publications for the LT 101, T53, and T55 engine models. This GTE Index is updated weekly on Honeywell's Technical Publications website: http://portal.honeywell.com/wps/portal/aero. Hardcopies are printed and distributed quarterly. Copies of documents, including this GTE Index, may be ordered through Honeywell's website at: http://portal.honeywell.com/wps/portal/aero or by contacting Mr. Jeff Tormanen at:
