Subject: Learjet 40 Temporary Flight Manual Change The following summary describes the highlights of this temporary flight manual change. PERFORMANCE NOISE LEVELS Revises noise levels summary material, noise charts for some performance codes, and certified noise levels description. NOTICE This Flight Manual Temporary Change is approved by the FAA on behalf of the European Aviation Safety Agency (EASA), using the bilateral arrangement between the FAA and EASA. This Flight Manual Temporary Change was prepared in accordance with European requirements. Reference approval number 10050353, dated 1 September 2014. TFM 2012-07 <Change #> Highlights-1 TEMPORARY FLIGHT MANUAL CHANGE Publications Affected: Learjet 40 AFM — FM-132 Learjet 40 AFM — FM-132 (Metric) Description of Change: Replace NOISE LEVELS (Section V). Filing Instructions: Insert the appropriate page of this temporary change, according to performance code, in the affected AFM adjacent to the pages containing NOISE LEVELS (Section V) and retain until further notice. Record this change in the “Log of Temporary Flight Manual Changes” at the front of the AFM. Replace the NOISE LEVELS section of Performance with the appropriate page according to performance code: FAA APPROVED DATE for MARGARET KLINE, MANAGER AIRCRAFT CERTIFICATION OFFICE FEDERAL AVIATION ADMINISTRATION WICHITA, KANSAS TFM 2012-07 Page 1 of 2 Performance Data NOISE LEVELS The following noise levels comply with 14 CFR Part 36, Appendix B (Stage 4) maximum noise level requirements and were obtained by analysis of approved data from noise tests conducted under the provisions of Part 36, Amendment 36-28. The noise measurement and evaluation procedures used to obtain these noise levels are considered by FAA to be equivalent to the Chapter 4 noise level required by the International Civil Aviation Organization (ICAO) in Annex 16, Volume 1, Appendix 2, Amendment 7, effective March 21, 2002. No determination has been made by the Federal Aviation Administration that the noise levels in this manual are or should be acceptable or unacceptable for operation at, into, or out of any airport. These noise values are stated for reference conditions of standard atmospheric pressure at sea level, 25°C ambient temperature, 70% relative humidity, and zero wind. CERTIFIED NOISE LEVELS Flyover and lateral noise levels were determined at the maximum takeoff weights listed below, 137 KIAS climb speed, 8° flaps, and anti-ice systems off. The flyover noise level includes an engine power cutback to a thrust that allows level flight in the event of an engine failure. Landing approach noise levels were determined for a three degree glide slope with gear down, maximum landing weights listed below, approach speed of 133 KIAS, and 40° flaps. The noise levels established in compliance with 14 CFR Part 36, Appendix B (Stage 4) are: NOISE LEVEL IN EPNdB CONDITION ACTUAL MAXIMUM ALLOWABLE 85.1 94 73.7 89 93.4 98 Lateral 20,350 lb (9231 kg) Flyover 20,350 lb (9231 kg) Approach 19,200 lb (8709 kg) Page 2 of 2 EFFECTIVITY B TFM-2012-07 Performance Data NOISE LEVELS The following noise levels comply with 14 CFR Part 36, Appendix B (Stage 4) maximum noise level requirements and were obtained by analysis of approved data from noise tests conducted under the provisions of Part 36, Amendment 36-28.
