Ensure that airplane flight manuals of airplanes equipped with CF34-1 or CF34-3 engines clearly state the minimum airspeed required for engine core rotation and that, if this airspeed is not maintained after a high power, high altitude sudden engine shutdown, a loss of in-flight restart capability as a result of core lock may occur.

Issued: 20-NOV-2006 | To: FAA | A-06-72 |
Require that operators of CRJ-100, -200, and -440 airplanes include in airplane flight manuals the significant performance penalties, such as loss of glide distance and increased descent rate, that can be incurred from maintaining the minimum airspeed required for core rotation and windmill restart attempts.

Issued: 20-NOV-2006 | To: FAA | A-06-73 |
Review the design of turbine-powered engines (other than the CF34-1 and CF34-3, which are addressed in Safety Recommendation A-06-70) to determine whether they are susceptible to core lock and, for those engines so identified, require manufacturers of airplanes equipped with these engines to perform high power, high altitude sudden engine shutdowns and determine the minimum airspeed to maintain sufficient core rotation so that all methods of in-flight restart can be accomplished. (Open - Acceptable Response) |
Issued: 20-NOV-2006 | To: FAA | A-06-74 |
For those airplanes with engines that are found to be susceptible to core lock (other than the CF34-1 and CF34-3, which are addressed in Safety Recommendation A-06-71), require airplane manufacturers to incorporate information into airplane flight manuals that clearly states the potential for core lock; the procedures, including the minimum airspeed required, to prevent this condition from occurring after a sudden engine shutdown; and the resulting loss of in-flight restart capability if this condition were to occur. (Open - Acceptable Response) |
Issued: 20-NOV-2006 | To: FAA | A-06-75 |
Require manufacturers to determine, as part of 14 Code of Federal Regulations Part 25 certification tests, if restart capability exists from a core rotation speed of 0 indicated rpm after high power, high altitude sudden engine shutdowns. For those airplanes determined to be susceptible to core lock, mitigate the hazard by providing design or operational means to ensure restart capability. (Open Acceptable Alternate Response) |
Issued: 20-NOV-2006 | To: FAA | A-06-76 |
Establish certification requirements that would place upper limits on the value of the minimum airspeed required and the amount of altitude loss permitted for windmill restarts. (Open - Acceptable Response) |
Issued: 23-JAN-2007 | To: FAA | A-07-1 |
Work with members of the aviation industry to enhance the training syllabuses for pilots conducting high altitude operations in regional jet airplanes. The syllabuses should include methods to ensure that these pilots possess a thorough understanding of the airplanes performance capabilities, limitations, and high altitude aerodynamics. (Open - Acceptable Response) |
Issued: 23-JAN-2007 | To: FAA | A-07-10 |
Require that all 14 Code of Federal Regulations Part 121 operators establish Safety Management System programs. (Closed - Acceptable Action) |
Issued: 23-JAN-2007 | To: FAA | A-07-11 |
Strongly encourage and assist all regional air carriers operating under 14 Code of Federal Regulations Part 121 to implement an approved Aviation Safety Action Program and an approved Flight Operational Quality Assurance program. (Closed - Acceptable Action) |
Issued: 23-JAN-2007 | To: FAA | A-07-2 |
Determine whether the changes to be made to the high altitude training syllabuses for regional jet airplanes, as requested in Safety Recommendation A-07-1, would also enhance the high altitude training syllabuses for all other transport-category jet airplanes and, if so, require that these changes be incorporated into the syllabuses for those airplanes. (Open - Acceptable Response) |
Issued: 23-JAN-2007 | To: FAA | A-07-3 |
Require that air carriers provide their pilots with opportunities to practice high altitude stall recovery techniques in the simulator during which time the pilots demonstrate their ability to identify and execute the appropriate recovery technique. (Open - Acceptable Response) |
Issued: 23-JAN-2007 | To: FAA | A-07-4 |
Convene a multidisciplinary panel of operational, training, and human factors specialists to study and submit a report on methods to improve flight crew familiarity with and response to stickpusher systems and, if warranted, establish training requirements for stickpusher-equipped airplanes based on the findings of this panel. (Closed - Unacceptable Action/Superseded) |
Issued: 23-JAN-2007 | To: FAA | A-07-5 |
Verify that all Canadair regional jet operators incorporate guidance in their double engine failure checklist that clearly states the airspeeds required during the procedure and require the operators to provide pilots with simulator training on executing this checklist. (Closed - Acceptable Action) |
Issued: 23-JAN-2007 | To: FAA | A-07-6 |
Require regional air carriers operating under 14 Code of Federal Regulations Part 121 to provide specific guidance on expectations for professional conduct to pilots who operate nonrevenue flights. (Open Acceptable Alternate Response) |
Issued: 23-JAN-2007 | To: FAA | A-07-7 |
For those regional air carriers operating under 14 Code of Federal Regulations Part 121 that have the capability to review flight data recorder (FDR) data, require that the air carriers review FDR data from nonrevenue flights to verify that the flights are being conducted according to standard operating procedures. (Open Acceptable Alternate Response) |
Issued: 23-JAN-2007 | To: FAA | A-07-8 |
Work with pilot associations to develop a specific program of education for air carrier pilots that addresses professional standards and their role in ensuring safety of flight. The program should include associated guidance information and references to recent accidents involving pilots acting unprofessionally or not following standard operating procedures.
