| Issued: -- | To: NTSB | NTSB Safety Recommendation A-07-12 |
| Require that operational training in the Cessna 560 airplane emphasize the airplane flight manual requirements that pilots increase the airspeed and operate the deice boots during approaches when ice is present on the wings. |
| Issued: -- | To: NTSB | NTSB Safety Recommendation A-07-13 |
| Require that all pilot training programs be modified to contain modules that teach and emphasize monitoring skills and workload management and include opportunities to practice and demonstrate proficiency in these areas. |
| Issued: -- | To: NTSB | NTSB Safety Recommendation A-07-14 |
| Require manufacturers and operators of pneumatic deice boot-equipped airplanes to revise the guidance contained in their manuals and training programs to emphasize that leading edge deice boots should be activated as soon as the airplane enters icing conditions.
(This safety recommendation supersedes Safety Recommendation A-98-91) |
| Issued: -- | To: NTSB | NTSB Safety Recommendation A-07-15 |
| Require that all pneumatic deice boot-equipped airplanes certified to fly in known icing conditions have a mode incorporated in the deice boot system that will automatically continue to cycle the deice boots once the system has been activated. |
| Issued: -- | To: NTSB | NTSB Safety Recommendation A-07-16 |
| When the revised icing certification standards (recommended in Safety Recommendations A-96-54 and A-98-92) and criteria are complete, review the icing certification of pneumatic deice boot-equipped airplanes that are currently certificated for operation in icing conditions and perform additional testing and take action as required to ensure that these airplanes
fulfill the requirements of the revised icing certification standards.

| Issued: -- | To: NTSB | NTSB Safety Recommendation A-07-17 |
| Require modification of the Cessna 560 airplane’s stall warning system to provide a stall warning margin that takes into account the size, type, and distribution of ice, including thin, rough ice on or aft of the protected surfaces. |
| Issued: -- | To: NTSB | NTSB Safety Recommendation A-96-54 |
| Revise the icing criteria published in 14 Code of Federal Regulations Parts 23 and 25, in light of both recent research into aircraft ice accretion under varying conditions of liquid water content, drop size distribution, and temperature, and recent developments in both the design and use of aircraft. Also, expand the Appendix C icing certification envelope to
include freezing drizzle/freezing rain and mixed water/ice crystal conditions, as necessary. |
| Issued: -- | To: NTSB | NTSB Safety Recommendation A-98-92 |
| With the National Aeronautics and Space Administration and other interested avation organizations, conduct additional research to identify realistic ice accumulations, to include intercycle and residual ice accumulations and ice accumulations on unprotected surfaces aft of the deicing boots, and to determine the effects and criticality of such ice accumulations; further, the information developed through such research should be incorporated into aircraft certification requirements and pilot training programs at all levels. |
