Which system the reports file it under last ten years
Approved replacement parts 2 parts manufacturer approvals
A parts manufacturer approval (PMA) lets a company other than the aircraft's maker make a encoder and sell it as an approved part for the models named. These are the companies holding such approvals for a encoder:
Sources: the FAA's service difficulty reports since 1995 (a report is a part that failed and was fixed, as filed by an airline, repair station or owner; the count shows reporting as much as reliability) and the parts manufacturer approvals in the FAA's Dynamic Regulatory System. The part name is the reporters' and the approval holders' own words, reduced to the first plain words so that spellings meet.
