JohnRich 4 #1 July 15, 2008 Tell me about the "fire warning" lights in an DHC-6 Otter. Do they often come on falsely, when there really isn't a fire in the engine? If the plane is on the ground and a fire warning light comes on for one of the engines, and you don't see flames and smoke, is there anything you can practically do to verify that there really is a problem, before dumping the fire extinguisher bottle into the engine? The fire extinguisher bottle costs $4,000 to replace, plus the engine has to be cleaned and checked out by an A&P before going back into service. Does the fire bottle just spray CO2, or is it a powdered mixture? Quote Share this post Link to post Share on other sites

From there it's just a quick visual inspection and then a judgement call from the pilot. Quote Does the fire bottle just spray CO2, or is it a powdered mixture? Most aviation extinguishers are halon based. Note: I'm not a pilot. So these are my best guesses. Quote Share this post Link to post Share on other sites
