Narrative:

On oct/fri/04, I received a letter of investigation concerning a paperwork error on a B737-300. The letter reads: 'in reviewing the aircraft's flight/maintenance log page XXXX dated aug/thu/04 indicates you were the mechanic that signed for one of these discrepancies and you found the engine egt within the maintenance manual limits. However, there is no documentation as to what section of the maintenance manual was used to make the within 'maintenance manual limits' determination. It appears you may have performed maintenance contrary to the maintenance procedures manual and title 14 code of the federal regulations.' I have obtained a copy of the log page in question as well as a copy of the maintenance procedures manual section that pertains to the 'within maintenance manual limits,' both of which will be fixes with this report, continued on a copy of this page marked 2A chapter 05-08 paragraph G item 24C states, 'entries such as 'repaired,' 'ok for service,' within limits,' etc, are acceptable when accompanied by a description or manual reference of how the determination was made. I believe that the description in the action taken block of the log page describes how the determination was made, thereby satisfying chapter 05-08 paragraph G item 24C of the maintenance procedures manual.
