Service Bulletin Index

Looking for the latest service bulletins? Our Service Bulletin Index allows you to search for new and previously issued service bulletins based on compliance codes, engine family and model, and more.
Spare Parts Bulletin Index

Our Spare Parts Bulletin Index allows you to search for new and previously issued bulletins about basic part number changes that allow our service centers to incorporate newly identified components into an engine unit. With several options by which to search (including by bulletin number, engine family and more) finding the information you seek has never been easier.
Service Information Letter Index

Looking for the latest P&WC-approved maintenance techniques and procedures? Check out our Service Information Letter Index that contains an archived history of issued letters, including the latest ones for help maintaining our products to the highest standard.
Revision Status Report

The revision date in the Technical Publications Status Report reflects the technical cut-off date for information incorporated into that specific revision. When a publication such as a Maintenance Manual, Illustrated Parts Catalog or other document, does not reflect the revision level stated in the Technical Publications Status Report, a current revision will be distributed.
Service Bulletin Compliance Codes

Please note the Service Bulletin (SB) compliance codes provided on our corporate website come from Service Information Letter SIL GEN-030 which is the master source for SB compliance codes information. In case of a discrepancy, SIL GEN-030 prevails.
