See what customers are saying about SmartStem!
“If you saved the airplane from having a low tire and damaging it the payback
was instant… In our opinion SmartStem paid back instantly; it’s a safer
operation for us, it’s an easier operation.”
“I think it’s tremendous — from somebody who wasn’t very much sold on the idea
to a situation where I don’t know what we would do without it. I mean it is just
that much of a change for me and our operation.”

- Wayne Smith, Maintenance Manager, CommScope,
Hickory, NC
|
"We've had SmartStem installed in our Lear60 since November 2010. We've
incorporated tire pressure as a task we do as we pre-flight the airplane. We've
gone as long as two months without adding air to the tire, so that in itself
saves about $100 every time. I think one of the major benefits is the increased
safety that you get by the flight crew knowing what the condition of their tires
is."

“Prior to going to a continuous checking process, we were seeing our tires wear
out at around 150 to 175 cycles. We’ve now had main gear tires that have gone
293 cycles, operating in and out of a 3,500 foot runway."

- Jad Donaldson, Chief Pilot Avfuel Corporation, Ann Arbor, MI |
“The single most important thing to prevent over-deflection and tire-related
events is: Proper Tire Inflation. There are devices out there that that you can
use to make it easier. For example, Crane Aerospace & Electronics has SmartStem,
which is a temperature sensing valve stem with a wand for checking, makes it a
lot easier.”

- Keat Pruszenski, Engineer Retired from Michelin Aircraft Tires |
“The technology provides numerous benefits including reduced maintenance costs,
improved convenience, and automatic tracking of tire pressure checks – adding an
extra measure of safety and extending tire life. It is also designed to be
easily retrofitted on existing aircraft since it is compatible with all standard
tire maintenance equipment.”
- Dassault Falcon Jet Corp. Monday, October 29, 2012 - Dassault Falcon
Offers SmartStem® Wireless Tire Pressure System on Falcon 50 Aircraft
"All the negative aspects of using a tire gauge have been removed - things like
the loss of nitrogen when we check tire pressures, debris entering the stem when
you check it, or unseating the valve stem and having it not seat properly and
losing tire pressure that way.”
- Kevin Hanlon, Pilot Red River Resources, Phoenix, AZ

Is my aircraft model covered to allow for SmartStem
installation?
A complete
list of SmartStem certifications can be found on the
certification tab.
-
What is the basis of certification for my large commercial or regional aircraft?
For details of the certification basis please see the complete certifications
list located on the certification tab. Some of the aircraft are certified
through a type cert modification executed by the aircraft OEM. Other aircraft
are certified through an STC.
-
If my aircraft is covered under an FAA STC how do I know if an alternate
registration authority (EASA or Transport Canada) STC exists for my aircraft?
We are continuing to gain new
international certifications for our existing FAA STCs each day. For the latest
certification approvals please refer to the certifications tab. If you require
an STC from another authority, please contact us for the latest plans and
updates.
-
Do I need to replace the tires or have the wheel non-destructive tested
prior to installation of SmartStem sensors?
No! SmartStem can
be installed on any aircraft via detailed installation instructions. There is no
requirement to replace tires or NDT the wheels. Please refer to your wheel CMM
to determine the requirements for wheel rebalancing and whether or not it is
required following installation of SmartStem.

Yes. The HHR will read and store data from any aircraft with SmartStem
sensors installed.
-
How long does it typically take to install SmartStem on my
aircraft?
Approximately 2 hours, including nose wheel balancing
prior to placing the aircraft back in service. The aircraft will need to be
jacked up, nitrogen removed from the tires, stem removed, SmartStem installed, nitrogen
filled, nose wheel(s) balanced. Can also be performed during tire/wheel
servicing or replacement.
