Document Title: Clarification for Non-TSO Functions in Seats
Summary: On June 6, 2014, the FAA issued Technical Standard Order (TSO)-C127b, Rotorcraft, Transport Airplane, and Small Airplane Seating Systems, that included new requirements for non-TSO functions. Based on the non-TSO criteria in TSO-C127b, there is confusion on how to comply with TSO-C127b. The intent of this policy is to clarify how the non-TSO function (NTF) policy applies to TSO seating systems.
