SERVICE DOCUMENTS
Six categories of Service Documents may be issued by TCM ranging from mandatory
(Category 1) to informational (Category 6). Definitions of the categories are listed below:
NOTE: Upon FAA approval, TCM service documents are published and available on
TCMLINK. Service Documents which contain updates to the Instructions for
Continued Airworthiness must be inserted in the affected manual until such time the
manual is revised to include the Service Document instructions or the Service
Document is cancelled or superseded. The Service Document cover page shall list
specific engine manuals affected by the Service Document’s changes to the
Instructions for Continued Airworthiness.
Category 1: Mandatory Service Bulletin (MSB)
Used to identify and correct a known or suspected safety hazard which has been incorporated in
whole or in part into an Airworthiness Directive (AD) issued by the FAA or have been issued at
the direction of the FAA by the manufacturer requiring compliance with an already-issued AD (or
an equivalent issued by another country’s airworthiness authority). May contain updates to
TCM’s Instructions for Continued Airworthiness to address a safety issue.
Category 2: Critical Service Bulletin (CSB)
This category identifies a condition that threatens continued safe operation of an aircraft,
persons or property on the ground unless some specific action (inspection, repair, replacement,
etc.) is taken by the owner or operator. Documents in this category are candidates for
incorporation into an FAA Airworthiness Directive. May contain updates to TCM’s Instructions for
Continued Airworthiness to address a safety issue.
Category 3: Service Bulletin (SB)
Information which the product manufacturer believes may improve the inherent safety of an
aircraft or aircraft component; this category includes the most recent updates to Instructions
for Continued Airworthiness.
Category 4: Service Information Directive (SID)
The manufacturer directs the owner/operator/mechanic in the use of a product to enhance
safety, maintenance or economy. May contain updates to TCM’s Instructions for Continued
Airworthiness in the form of maintenance procedures or specifications.
Category 5: Service Information Letter (SIL)
This category includes all information (not included in categories 1 through 4) that may be useful
to the owner/operator/technician. May contain updates to TCM’s Instructions for Continued
Airworthiness for optional component installations, which are not covered in the Applicable
Operator, Maintenance, or Overhaul Manuals.
Category 6: Special Service Instruction (SSI)
This category is used to address an issue limited to specific model and/or serial number
engines. TCM will distribute SSI notification directly to the affected engine’s owners. SSIs will not
be included in the general service document set but will be made available through TCM
Customer Service to owners of the affected engines only. An SSI may contain updates to the
Instructions for Continued Airworthiness applicable to the listed engines.
