FAA approves SmartStem for Part 135 pilots on all certified aircraft
LYNNWOOD, Wash – August 13, 2012 – Crane Aerospace & Electronics, a segment of Crane Co. (NYSE:CR), has announced that the Federal Aviation Administration (FAA) has issued a letter stating their legal opinion allowing the SmartStem® Wireless Tire Pressure Monitoring System to be used by Part 135 pilots to check tire pressure on all certified aircraft. There are presently no other products on the market that allow a Part 135 pilot to check their own tires.
“It is our opinion that pilots conducting part 135 operations may use the SmartStem to perform daily tire pressure checks as a pre-flight task if the system has been properly installed on the aircraft by means of an STC or other FAA approval," the FAA said in their letter to Crane, dated July 8, 2012.
SmartStem Tire Pressure Sensors are already certified for use on a variety of other business jets and Crane is in the process of certifying SmartStem on additional business, regional, and large commercial aircraft.
To fit an aircraft with SmartStem technology, the existing tire inflation valve stem is simply replaced with a special valve stem containing integral sensors. SmartStem communicates tire pressure, temperature, and other stored information wirelessly to a Handheld Reader without the use of an internal battery in the stem. Since this information is communicated wirelessly and does not require the removal of the valve cap, no gas is lost during routine tire pressure checks.
