Appendix 2 Page 1 (and 2) APPENDIX 2. EVOLUTION/OPTIMIZATION DEFINITIONS
a. Confidence Level. The likelihood that the overall fleet performance lies within the range specified by the sample fleet performance. The confidence level is usually expressed as a percentage.
b. Evolution/Optimization. Task performed through the management of data as a means to assure the continued applicability and effectiveness of the task, while improving the integrity of the process.
c. Line Maintenance. Routine check, inspection, and malfunction rectification performed en-route and at base stations during transit, turn-around, or night stop.
d. Nonmetallics. Any structural material made from fibrous or laminated components bonded together by a medium. Materials such as graphite epoxy, boron epoxy, fiberglass, kevlar epoxy, acrylics, and the like are nonmetallics. Nonmetallics include adhesives used to join other metallic or nonmetallic structural materials.
e. Non-Routine Task. A task is non-routine when it is not a planned/scheduled task coming from the operator’s/manufacturer’s maintenance program.
f. Pilot Report (PIREP). Suspected or known malfunctions or unsatisfactory conditions that are entered by the flightcrew into the aircraft log and require maintenance action.
g. Qualified Federal Aviation Administration (FAA) Maintenance Review Board (MRB) Chairperson. An airworthiness inspector with working knowledge of the MRB process must have system/structures training on particular aircraft and have Maintenance Steering Group—3rd Task Force (MSG-3) formal training.
h. Risk Management (RM). The systematic application of management policies, procedures, and practices to the tasks of identifying, analyzing, evaluating, treating, and monitoring risk.
i. Safety Management. The application of engineering and management principles, criteria, and techniques to optimize safety. It is an integrated and comprehensive engineering effort.
j. Structural Significant Item (SSI). Any detail, element, or assembly that contributes significantly to carrying flight, ground, pressure, or control loads, and whose failure could affect the structural integrity necessary for the safety of the aircraft.
k. Unscheduled Maintenance. Maintenance performed to restore an item to a satisfactory condition by correcting a known or suspected malfunction and/or defect.
Appendix 3 APPENDIX 3. POLICY AND PROCEDURES HANDBOOK (PPH) FORMAT This appendix intends to provide standardized and harmonized policy in the development of a PPH for a new product. It is encouraged that all industry applicants’ PPH documents be developed containing the same basic data and information, as applicable, to provide for a complete, consistent, and quality process. It is not required that existing PPHs be revised to meet these standards.
Regulatory authorities and industry experience have indicated that the following information is expected in each PPH, as applicable, for the successful latest version of the Maintenance Steering Group (MSG) process and development of a Maintenance Review Board Report (MRBR).
