Notice of availability and request for comments.


The FAA invites public comments on its proposed policy memorandum to improve the reporting processes of discrepancies discovered in the data used among persons directly involved in the certification of aircraft seats. This Notice also invites the public to comment on the proposed policy to standardize the resolution of discrepancies discovered on aircraft seats in relation to the minimum performance standard of the specific TSO.


Comments must be received by May 20, 2003.

In 2000, the FAA and industry formed a team to investigate and implement procedures to streamline the certification of aircraft seats. One area identified for improvement is the means of communicating discrepancies found on seats after the issuance of the TSO approval by the person or organization performing the seat certification/installation process. Currently, seat discrepancies were resolved in the most expeditious manner possible, but this process does not allow for the resolution of systemic problems. However, the proposed policy for reporting discrepancies discovered on aircraft seats will help to ensure that all stakeholders in the seat certification program are made aware of the problem so that root causes are readily identified and resolved in a standardized manner. Note that the development of the proposed process recognized that the discrepancies are discovered after the TSO approval, and that the type design status of the aircraft in which the seats are installed in taken into consideration. Ultimately, the proposed process clarifies steps that must be achieved before an aircraft is eligible for type design approval and identifies who is responsible for resolving the discrepancy.
