MARPA has released the latest revisions of the MARPA 1100 Standard and MARPA Continued Operation Safety (COS) guidance. These revisions improve both documents.
The MARPA 1100 Standard is a streamlined program for Parts Manufacturer Approval applications. It reflects a standard mechanism for compiling applications for FAA PMAs for non-safety-significant (NSS) aircraft parts. These are parts whose failure would have little or no effect on the continued safe flight and landing of an aircraft.
MARPA continues to work with the FAA to help develop corollary FAA guidance to explain to FAA employees the public safety benefits of the program, and to advise FAA employees on how to handle PMA applications properly prepared under the MARPA 1100 standard. The program will benefit both the FAA and the PMA manufacturing community by allowing the FAA to more quickly approve applications for NSS PMA parts and to focus its limited certification resources on more safety-sensitive issues.
MARPA COS guidance is designed to help PMA manufacturers implement an effective COS program to satisfy the need for PMA holders to be responsible for the continued operational safety of their aircraft parts. The MARPA COS program uses three philosophies — problem prevention, part monitoring, and problem response — to support operational safety of a manufactured part.
