• In 2017, the FAA implemented amendment 23-64 to part 23 airworthiness standards for normal category airplanes • This briefing will address: 1. Reasons for change 2. Characteristics of performance- based rules 3. Key aspects of amendment 23- 64 4. Means of compliance to part 23 5. Consensus standards and ASTM International 6. Additional Under current 14 CFR Part 23, airplanes are certified in one or more of the following categories: normal, utility, acrobatic, and commuter. Classification primarily depends upon the types of maneuvers to be performed, number of seats, number of engines, and maximum certificated takeoff weight. 13. Will the FAA continue to certify airplanes in Sec. 23.221 Spinning. [(a) Normal category airplanes.A single-engine, normal category airplane must be able to recover from a one-turn spin or a three-second spin, whichever takes longer, in not more than one additional turn after initiation of the first control action for recovery, or demonstrate compliance with the optional spin resistant requirements of this section.

(1) The airplane is assumed to be subjected to symmetrical vertical gusts in level flight. The resulting limit load factors must correspond to the conditions determined as follows: (i) Positive (up) and negative (down) gusts of 50 f.p.s. at V C must be considered at altitudes between sea level and 20,000 feet.
