Part 136—commercial Air Tours and National Parks Air Tour Management

(j) Engine condition monitoring. (1) The certificate holder must establish an engine-condition monitoring program to detect deterioration at an early stage and to allow for corrective action before safe operation is affected. (2) This program must describe the parameters to be monitored, the method of data collection, the method of analyzing data, and the process for taking corrective action. (3) The program must ensure that engine limit margins are maintained so that a prolonged engine-inoperative diversion may be conducted at approved power levels and in all expected environmental conditions without exceeding approved engine limits. This includes approved limits for items such as rotor speeds and exhaust gas temperatures. (k) Oil consumption monitoring. The certificate holder must develop an engine oil consumption monitoring program to ensure that there is enough oil to complete each ETOPS flight. APU oil consumption must be included if an APU is required for ETOPS. The operator’s consumption limit may not exceed the manufacturer’s recommendation. Monitoring must be continuous and include oil added at each ETOPS departure point. The program must compare the amount of oil added at each ETOPS departure point with the running average consumption to identify sudden increases. (l) APU in-flight start program. If an APU is required for ETOPS, but is not required to run during the ETOPS portion of the flight, the certificate holder must have a program acceptable to the FAA for cold soak in-flight start and run reliability. (m) Maintenance training. For each airplane-engine combination, the certificate holder must develop a maintenance training program to ensure that it provides training adequate to support ETOPS. It must include ETOPS specific training for all persons involved in ETOPS maintenance that focuses on the special nature of ETOPS. This training must be in addition to the operator’s maintenance training program used to qualify individuals for specific airplanes and engines. (n) Configuration, maintenance, and procedures (CMP) document. The certificate holder must use a system to ensure compliance with the minimum requirements set forth in the current version of the CMP document for each airplane-engine combination that has a CMP. (o) Reporting. The certificate holder must report quarterly to the CHDO and the airplane and engine manufacturer for each airplane authorized for ETOPS. The report must provide the operating hours and cycles for each airplane. G135.2.9 Delayed compliance date for all airplanes. A certificate holder need not comply with this appendix for any airplane until August 13, 2008.
