NTSB Issues Two New Safety Alerts

The National Transportation Safety Board recently issued two new Aviation Safety Alerts (SA). SA-080 (https://www.ntsb.gov/safety/safety-alerts/Documents/SA-080.pdf) alerts pilots and mechanics to “stay in the groove” and check the integrity of aircraft ignition switches. The SA warns that over time, key-type ignition switches and associated keys can become worn such that it is possible to remove the key from a switch position other than the OFF position. This can result in switch positioning errors and an unintended engine start. An accompanying video is available here: https://youtu.be/JDnnXjNb2vc.

SA-081 (https://www.ntsb.gov/safety/safety-alerts/Documents/SA-081.pdf) reminds pilots of how critical it is to properly maintain engine failures in multi-engine aircraft, especially at low altitudes. The SA urges pilots to be thoroughly familiar with the recommended procedures and checklists for one engine inoperative operations — particularly the memory checklist items — in the airplane flight manual and pilot operating handbook. Be sure to also check out the FAA’s FlySafe fact sheet on Vmc (minimum control airspeed with critical engine inoperative) here: http://www.faa.gov/news/safety_briefing/2017/media/SE_Topic_17_05.pdf.
