Automotive Gasoline Supplemental Type
Certificate (STC)
Wayne Mulgrew used our STC and 91-octane automotive
gasoline in his Robinson R22 to set an FAI altitude record of
over 19,000 feet.
Click here to order your STC today, and see the fuel
savings and increased engine power and efficiency in your
helicopter. The STC pays for itself in less than 50 hours of
operation on autogas.
STCs are available for the R22, R44 and Schweizer 269C-1.
We have run up to 13 helicopters at a time on autogas and
have experienced no problems in nearly 26,000 hours of operation. And
we have never received malfunction reports from any customers or from the FAA.
Approvals: Use of automotive gasoline under the
provisions of these STCs is approved by the FAA (EASA approvals pending).
Automotive fuel has the following advantages for the
helicopter operator:
- Smoother operation: no pedal twitch on hover
(no plug fouling).
- More power available due to better combustion
efficiency.
- Lower fuel consumption (approximately 0.5 to 1
gph less) due to better efficiency.
- Hover at approximately 1” lower manifold
pressure due to better engine efficiency.
- Longer spark plug life due to absence of lead
fouling.
- Approximately $15-$30/hr. lower operating cost
when compared to 100LL.
- Universal availability of 91-octane automotive
gasoline.
- No hesitation in engine acceleration during
power recovery.
- Allows the use of anti-icing isopropyl alcohol for
sub-freezing winter operations.
