2017 Aircraft Fuel Senders AML STC PRESS RELEASE

Bend, OR  March 15th 2017

Tractor Fuel senders need not apply, CiES Inc. announces that the best-selling TSO’d digital

and aircraft specific fuel quantity senders are now approved for STC installation in

most Cessna, Piper, Beech, Mooney & Maule aircraft. 

CiES TSO'd CC284022 Series  &  FAA STC SA02511SE

CiES is a new technology for measuring fuel quantity in aircraft.  The CiES patented fuel sender technology is a digital non-contact method designed exclusively for aircraft and the aircraft operating environment.    We replace existing senders that were sourced from the automotive or agricultural field that have been a mainstay in general aviation aircraft.   

CiES is the general aviation industry overwhelming choice for fuel quantity senders,  over 1,750 aircraft in the field, already fly with CiES digital fuel quantity sensing systems.  CiES fuel quantity systems are included on all new Cirrus Aircraft SR20, SR22, SR50 Jet, Quest Kodiak, Vulcanair P68, Tecnam, Gippsland GA10, CAIGA with more to be added in the coming months. 

CC284022 Series Fuel quantity senders have amassed over 580,000 hours of operation in OEM aircraft and have an outstanding record of near zero in service removals with over 12,000 senders fielded.  CiES has the experience and capability to insure that GA aircraft fuel quantity can and will be accurate in the aircraft of the future.

​Scott Philiben, CiES President, said “For years, pilots of type certificated aircraft have suffered with marginal fuel quantity systems.  These systems in many aircraft are repurposed fuel senders and gauges for agricultural equipment.  The current situation with these systems has gotten so bad that many pilots don’t trust or rely on the their fuel quantity instrument.  When you sit back and look at all the work arounds pilots now use to replace what should be quality fuel instrumentation something really had to be done.   Pilots are relying on work arounds such as calibrated sticks and warning timers that basically are still resulting in 3 to 4 fuel related accidents per week.    The plain truth  is that aircraft fuel quantity systems were really crying out for an new and better technology.”

Last year, in discussions with the FAA Small Aircraft Directorate, CiES illustrated how our technology could easily replace older failing fuel quantity indication.  The FAA, interested in bringing newer technology was aware of our success in OEM applications and the fit form and function capability of our design and opened the door for an AML retrofit STC. 

“said Melvin Johnson, FAA Small Aircraft Directorate Manager “I’m really encouraged that CiES has made the effort in getting an AML STC done.  Helping the GA fleet have accurate and dependable fuel indication will definitely have an impact on safety.”

The CiES digital fuel quantity system utilizes an advanced technology sensor system that allows repeatable accurate measurement of fuel in aircraft tank.  This patented sensor system allows fuel measurements down to a change in fuel level to less than 0.03 of an inch.   This measurement represents much less than 10 ths of a gallon of AVGAS or Jet A.  The non-contact measurement method insures a lifetime of trouble-free operation providing stable, consistent fuel level output.

The initial STC allows the CiES to replace the existing aircraft fuel quantity senders in:

Beech  33, 35, 36, 55, 58
Cessna 150, 152, 170, 172, 175 177, 177RG, 180, 182, 185, 206, 207, 210
Vulcanair P68
Cirrus  SR20 SR22  Fuel & TKS
Gippsland GA8                                
Piper PA22,PA23, PA24, PA28, PA30, PA31, PA32, PA39, PA44
Pilatus PC 6
American ChampionFairchild 24


More aircraft approvals are expected to follow shortly. 

​Founded in 2010, CiES’s  mission is to create the best aircraft systems for aviation and other high value markets.   With an
